OBJECTIVE: To evaluate the effect and summarize the characteristics of different treatment methods in repairing zygomatic defect. METHODS: A total of 37 patients with zygomatic defect were reviewed in the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from August 2012 to August 2019. According to the anatomical scope of defect, the zygomatic defects were divided into four categories: Class 0, the defect did not involve changes in zygomatic structure or continuity, only deficiency in thickness or projection; Class Ⅰ, defect was located in the zygomatic body or involved only one process; Class Ⅱ, a single defect involved two processes; Class Ⅲa, referred to a single defect involving three processes and above; Class Ⅲb, referred to zygomatic defects associated with large maxillary defects. The etiology, defect time, defect size and characteristics of zygomatic defects, the repair and reconstruction methods, and postoperative complications were collected and analyzed. Postoperative computed tomography (CT) data were collected to evaluate the outcome of zygomatic protrusion. Chromatographic analysis was used to assess the postoperative stability. RESULTS: Among the causes of defects, 25 cases (67.57%) were caused by trauma, and 11 cases (29.73%) were of surgical defects following tumor resection. We performed autologous bone grafts in 19 cases, 6 cases underwent vascularized tissue flap, 5 cases underwent external implants alone, and 7 cases underwent vascularized tissue flap combined with external implants. After the recovery of the affected side, the average difference of the zygomatic projection between the navigation group and the non-navigation group was 0.45 mm (0.20-2.50 mm) and 1.60 mm (0.10-2.90 mm), with a significant difference (P=0.045). Two patients repaired with titanium mesh combined with anterolateral thigh flap had obvious deformation or fracture of titanium mesh; 2 patients with customized casting prosthesis had infection after surgery and fetched out the prosthesis finally. CONCLUSION Autologous free grafts or alloplastic materials may be used in cases without significant structural changes. Pedicle skull flap or vascularized bone tissue flap is recommended for zygomatic bone defects with bone pillar destruction, chronic inflammation, oral and nasal communication or significant soft tissue insufficiency. Titanium mesh can be used to repair a large defect of zygomatic bone, and it is suggested to combine with vascularized bone flap transplantation.

Objective: To evaluate the effect of trifoliate flap design of radial forearm flap in reconstruction of defects after mouth floor cancer resection. Methods: From June 2016 to December 2019, 12 patients with defect after resection of mouth floor cancer were treated with trifoliate flap design of radial forearm flap. All of these patients were T2 stage, included 9 well-differentiated squamous cell carcinoma (SCC) and 3 moderate differentiated SCC. The defect size ranged from 8.0 cm×6.0 cm to 5.0 cm×4.5 cm after resection of tumor and neck dissection. All defects were repaired with trifoliate flap design of radial forearm flap. The flap size ranged from 8.0 cm×2.0 cm to 4.0 cm×1.5 cm, the donor site was sutured directly on Z plasty. Results: All flaps completely survived well. Both the wound and the donor site were stage Ⅰ healing. With the average follow-up of 38.6 months, the swallowing and speech function were satisfactory. Conclusions: Trifoliate flap design of radial forearm flap can effectively repair the postoperative defect of mouth floor cancer, and the donor site can be directly sutured on Z plasty. This technique can avoid forearm scar caused by skin grafting and the formation of the second donor site.

Objective: To explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

Objective: To investigate the clinical effects of free transplantation of expanded ilioinguinal flaps in the reconstruction of severe scar contracture after extensive burns. Methods: A retrospective observational study was conducted. From August 2017 to October 2021, 7 patients with severe scar contracture deformity caused by extensive burns were hospitalized in Tongren Hospital of Wuhan University & Wuhan Third Hospital, including 5 males and 2 females, aged 26-65 years, with scar area of 20 cm×4 cm-34 cm×14 cm. In the first stage, the rectangular skin and soft tissue expander (hereinafter referred to as the expander) with rated capacity of 500-600 mL were embedded above the inguinal ligament, and then normal saline was injected after stitch removal for expansion to meet the needs of repair surgery. In the second stage, the scar was removed by surgical excision to correct the deformity and release the adhesion and contracture; after the removal of the expanders, the expanded ilioinguinal free flaps were harvested. When a larger flap was needed, the paraumbilical perforator flap was harvested at the same time, and the flaps were transplanted to the secondary wound after scar resection. The number of embedded expanders, the total amount of injected normal saline, the expansion time, the complications of skin and soft tissue expansion, the number, area, thickness, and anastomotic vascular pedicles of the expanded ilioinguinal flaps being resected, the type of flaps used, the repair method of flap donor sites, and the survival of flaps after operation were observed and recorded. The long-term repair effect and donor site condition were followed up. At the last follow-up, the patients' satisfaction with the curative effect of each surgical site was investigated according to the grade 5 score of Likert scale. Results: A total of 10 expanders were embedded in 7 patients, of which 4 patients had 1 each and 3 patients had 2 each. The total volume of normal saline injected was 800-1 800 (1 342±385) mL, and the expansion time was 4-24 (11±5) months. One patient had the expander exposed due to infection after the expander being inserted, while the other patients had no complications of skin and soft tissue expansion. Totally 10 expanded ilioinguinal flaps with the area of 22 cm×6 cm-36 cm×16 cm ((326±132) cm²) and the thickness of 0.6-1.1 (0.77±0.16) cm were harvested. Among the 10 expanded ilioinguinal flaps, 5 were pedicled with the superficial circumflex iliac artery, 3 with the superficial abdominal artery with relatively large caliber, 1 with the common trunk of the superficial circumflex iliac artery and the superficial abdominal artery, and 1 flap was anastomosed with the superficial circumflex iliac artery and bridged the superficial abdominal artery for intra-arterial supercharge. Unilateral expanded ilioinguinal flap combined with ipsilateral paraumbilical perforator flap were harvested in 4 cases, bilateral expanded ilioinguinal flaps were harvested in 1 case, and unilateral expanded ilioinguinal flap was harvested in 2 cases. Except for 1 case being transplanted with autologous split-thickness scalp to repair the flap donor site after combined resection of bilateral expanded ilioinguinal flaps, the donor sites of the other patients were sutured directly. All the flaps survived after operation without tip necrosis or wound residue. Follow-up for 3-30 (15±10) months showed that the flap was soft and not bloated, the function and appearance of the recipient area were significantly improved compared with those before operation, and the appearance of the donor sites was good. At the last follow-up, the patients' satisfaction with the treatment effect of the surgical site scored 4-5 (4.5±0.4). Conclusions: The expanded ilioinguinal flap can be obtained in a large area. It has the advantages of rich blood supply, less damage to the donor site, concealed location, and being convenient to be resected and transplanted in combination with the paraumbilical perforator flap. It is suitable for the clinical reconstruction and treatment of severe scar contracture deformity after extensive burns.

Objective: To explore the clinical effects of three-dimensional printed preformed titanium mesh combined with latissimus dorsi muscle flap free transplantation in the treatment of wounds with skull defect after radical surgery of squamous cell carcinoma in the vertex. Methods: A retrospective observational study was conducted. From January 2010 to December 2019, 5 patients with squamous cell carcinoma in the vertex accompanied with skull invasion who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the Second Affiliated Hospital of Air Force Medical University, including four males and one female, aged 50 to 65 years. The original lesion areas ranged from 5 cm×4 cm to 15 cm×8 cm. The titanium mesh was prefabricated via three-dimensional technic based on the result the scope of skull resection predicted with computerized tomography three-dimensional reconstruction before surgery. During the first stage, the soft tissue defect area of scalp (8 cm×7 cm to 18 cm×11 cm) after tumor enlargement resection was repaired with the preformed titanium mesh, and the titanium mesh was covered with latissimus dorsi muscle flap, with area of 10 cm×9 cm to 20 cm×13 cm. The thoracodorsal artery/vein was anastomosed with the superficial temporal artery/vein on one side. The muscle ends in the donor site were sutured together or performed with transfixion, and then the skin on the back were covered back to the donor site. On the 10th day after the first-stage surgery, the second-stage surgery was performed. The thin intermediate thickness skin graft was taken from the anterolateral thigh to cover the latissimus dorsi muscle flap. The duration and intraoperative blood loss of first-stage surgery were recorded. The postoperative muscle flap survival after the first-stage surgery and skin graft survival after the second-stage surgery was observed. The occurrence of complications, head appearance, and recurrence of tumor were followed up. Results: The average first-stage surgery duration of patients was 12.1 h, and the intraoperative blood loss was not more than 1 200 mL. The muscle flaps in the first-stage surgery and the skin grafts in the second-stage surgery all survived well. During the follow-up of 6-18 months, no complications such as exposure of titanium mesh or infection occurred, with good shape in the recipient sites in the vertex, and no recurrence of tumor. Conclusions: Three-dimensional printed preformed titanium mesh combined with latissimus dorsi muscle flap free transplantation and intermediate thickness skin graft cover is an effective and reliable method for repairing the wound with skull defect after extended resection of squamous cell carcinoma in the vertex. This method can cover the wound effectively as well as promote both recipient and donor sites to obtain good function and appearance.

Objective: To explore the effects of expanded frontal-parietal pedicled flap in reconstructing cervical scar contracture deformity in children after burns. Methods: A retrospective observational study was conducted. From January 2015 to December 2020, 18 male children with cervical scar contracture deformity after burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, aged 4 to 12 years, including 10 cases with degree Ⅱ cervical scar contracture deformity and 8 cases with degree Ⅲ scar contracture deformity, and were all reconstructed with expanded frontal-parietal pedicled flap. The surgery was performed in 3 stages. In the first stage, a cylindrical skin and soft tissue expander (hereinafter referred to as expander) with rated capacity of 300 to 500 mL was placed in the frontal-parietal region. The expansion time was 4 to 6 months with the total normal saline injection volume being 2.1 to 3.0 times of the rated capacity of expander. In the second stage, expander removal, scar excision, contracture release, and flap transfer were performed, with the flap areas of 18 cm×9 cm to 23 cm×13 cm and the secondary wound areas of 16 cm×8 cm to 21 cm×11 cm after scar excision and contracture release. After 3 to 4 weeks, in the third stage, the flap pedicle was cut off and restored. The rated volume of placed expander, total normal saline injection volume, type of vascular pedicle of flap, survival of flap and reconstruction of scar after the second stage surgery were recorded. The neck range of motion and cervico-mental angle were measured before surgery and one-year after surgery. The appearance of neck, occurrence of common complications in the donor and recipient sites of children, and satisfaction of children's families for treatment effects were followed up. Data were statistically analyzed with paired sample t test. Results: All the patients successfully completed the three stages of operation. The rated volume of implanted expander was 300 mL in 6 children, 400 mL in 9 children, and 500 mL in 3 children, with the volume of normal saline injection being 630 to 1 500 mL. The type of vascular pedicle of flap was double pedicle in 13 cases and was single pedicle in 5 cases. All the flaps in 17 children survived well, and the secondary wounds after neck scar excision and contracture release were all reconstructed in one procedure. In one case, the distal blood supply of the single pedicled flap was poor after the second stage surgery, with necrosis of about 2.5 cm in length. The distal necrotic tissue was removed on 10 days after the operation, and the wound was completely closed after the flap was repositioned. In the follow-up of 6 months to 3 years post operation, the cervical scar contracture deformity in 18 children was corrected without recurrence. The flap was not bloated, the texture was soft, and the appearances of chin and neck were good. The range of motion of cervical pre-buckling, extension, left flexion, and right flexion, and cervico-mental angle in one year after operation were improved compared with those before operation (with t values of 43.10, 22.64, 27.96, 20.59, and 88.42, respectively, P<0.01). The incision in the frontal donor site was located in the hairline, the scar was slight and concealed. No complication such as cranial depression was observed in expander placement site, and the children's families were satisfied with the result of reconstruction. Conclusions: Application of expanded frontal-parietal pedicled flap in reconstructing the cervical scar contracture deformity in children after burns can obviously improve the appearance and function of neck, with unlikely recurrence of postoperative scar contractures, thus it is an ideal method of reconstruction.

Objective: To investigate the functional outcomes and postoperative complications of Cheng's GIRAFFE reconstruction after proximal gastrectomy. Methods: A descriptive case series study was conducted. Clinical data of 100 patients with adenocarcinoma of the esophagogastric junction who underwent Cheng's GIRAFFE reconstruction after proximal gastrectomy in Cancer Hospital of University of Chinese Academy of Sciences (64 cases), Zhejiang Provincial Hospital of Chinese Medicine (24 cases), Lishui Central Hospital (10 cases), Huzhou Central Hospital (1 case) and Ningbo Lihuili Hospital (1 case) from September 2017 to June 2021 were retrospectively analyzed. Of 100 patients, 64 were males and 36 were females; the mean age was (61.3 ± 11.1) years and the BMI was (22.7±11.1) kg/m(2). For TNM stage, 68 patients were stage IA, 24 were stage IIA and 8 were stage IIB. Postoperative functional results and postoperative complications of radical gastrectomy with Giraffe reconstruction were analyzed and summarized. Gastroesophageal reflux disease questionnaire (RDQ) score and postoperative endoscopy were used to evaluate the occurrence of reflux esophagitis and its grade (grade N, grade A, grade B, grade C, and grade D from mild to severe reflux). The continuous data conforming to normal distribution were expressed as (mean ± standard deviation), and those with skewed distribution were presented as median (Q1, Q3). Results: All the 100 patients successfully completed R0 resection, including 77 patients undergoing laparoscopic surgery and 23 patients undergoing laparotomy. The Giraffe anastomosis time was (38.6±14.0) min; the blood loss was (73.0±18.4) ml; the postoperative hospital stay was 9.5 (8.2, 13.0) d; the hospitalization cost was (6.0±0.3) ten thousand yuan. Fourteen cases developed perioperative complications (14.0%), including 7 cases of pleural effusion or pneumonia, 3 cases of anastomotic leakage, 2 cases of gastric emptying disorder, 1 case of gastrointestinal hemorrhage and 1 case of anastomotic stenosis, who were all improved and discharged after symptomatic management. Patients were followed up for (33.3±1.6) months. Eight patients were found to have reflux symptoms by RDQ scale six months after surgery, and 11 patients (11/100,11.0%) were found to have reflux esophagitis by gastroscopy, including 6 in grade A, 3 in grade B, and 2 in grade C. All the patients could control their reflux symptoms with behavioral guidance or oral PPIs. Conclusion: Cheng's GIRAFFE reconstruction has good anti-reflux efficacy and gastric emptying function; it can be one of the choices of reconstruction methods after proximal gastrectomy.

Objective: To investigate the clinical effects of free peroneal artery perforator flaps in repairing forefoot skin and soft tissue defect wounds assisted with three-dimensional computed tomography angiography (3D-CTA). Methods: A retrospective observational study was conducted. From March 2017 to September 2019, 15 patients with skin and soft tissue defect wounds in the forefoot were treated in the Department of Burn and Plastic Surgery of Yidu Central Hospital of Weifang, including 12 males and 3 females, with age of 18-60 years. The wound area on admission was 3.0 cm×3.0 cm-9.0 cm×8.0 cm. The 3D-CTA examination before operation was performed to select the peroneal artery perforating vessels with appropriate length of vascular pedicle and good blood perfusion. According to the wound area and the perforating vessels of the peroneal artery located by 3D-CTA, the peroneal artery perforator flaps of 3.5 cm×3.5 cm-9.5 cm×8.5 cm carried with lateral sural cutaneous nerve was designed and cut, and the nerve was anastomosed with the nerve of the wound. The wound in the donor site of the flap was directly sutured or covered with medium-thickness skin graft from the thigh. The consistencies of type, diameter, and perforating position of perforating vessel of the peroneal artery detected by 3D-CTA before the operation with those of the actual measurement during operation were observed. The length of time for flap cutting and the survival of the flap after operation were recorded. During follow-up of 12 months after the operation, the patients were instructed to evaluate the foot function according to the Maryland foot function score standard, and the wound healing in the donor area and the occurrence of complications affecting the motor function of limb were observed. Data were statistically analyzed with paired sample t test. Results: The types of peroneal artery perforating vessels in patients measured during the operation were septocutaneous perforator of 12 cases, musculocutaneous perforator of 2 cases, and musculomuscular septal perforator of 1 case, which were consistent with those measured by preoperative 3D-CTA. The diameter of the peroneal artery perforating vessel measured by preoperative 3D-CTA was (1.38±0.17) mm, which was close to (1.40±0.19) mm measured during the operation (t=0.30, P>0.05). The horizontal distance from the starting point of the perforating vessel to the outer edge of the shank was (42±6) mm, and the vertical distance from the starting point of the perforating vessel to the level of the lateral ankle tip was (219±14) mm measured by preoperative 3D-CTA, which were respectively close to (43±6) and (221±15) mm of intraoperative measurement (with t values of 0.46 and 0.38, respectively, P>0.05). The length of time for cutting flap was (31±6) min. All flaps survived post operation without vascular crisis. During follow-up of 12 months after the operation, the foot function was evaluated as excellent in 11 cases, good in 3 cases, and fair in 1 case, the donor site wound healed well, the scar was not noticeable with no contracture, and the motor function of joints was not affected. Conclusions: Free peroneal artery perforator flap is one of the effective methods to reconstruct skin and soft tissue defect wounds in the forefoot, and the risk of surgery can be reduced when the anatomical location of the perforating vessels is confirmed by 3D-CTA.

Objective: To explore the clinical effects of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns. Methods: A retrospective observational study was conducted. From May 2018 to April 2021, 12 male patients with thumb destructive defects caused by electrical burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, aged 27 to 58 years, including 10 cases with degree Ⅲ thumb defect and 2 cases with degree Ⅳ thumb defect after thorough debridement. The thumb was reconstructed with free hallux-nail flap combined with composite tissue flap of the second phalangeal bone, joint, and tendon with skin island. The donor site of hallux-nail flap was covered with artificial dermis in the first stage and performed with continuous vacuum sealing drainage, and covered with medium-thickness skin graft from the groin site in the second stage. The donor site in the second toe was filled and fixed with iliac bone strips. The survival of reconstructed thumb was observed 1 week after the reconstruction surgery, the survival of skin graft in the donor site of hallux-nail flap was observed 2 weeks after skin grafting, and the callus formation of the reconstructed thumb phalanx and the second toe of the donor foot was observed by X-ray 6 weeks after the reconstruction surgery. During the follow-up, the shape of reconstructed thumb was observed and the sensory function was evaluated; the function of reconstructed thumb was evaluated with trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association; whether the interphalangeal joints of the hallux and the second toe were stiff, the scar hyperplasia of the foot donor site, and whether the walking and standing functions of the donor feet were limited were observed. Results: One week after the reconstruction surgery, all the reconstructed thumbs of the patients survived. Two weeks after skin grafting, the skin grafts in the donor site of hallux-nail flap of 11 patients survived, while the skin graft in the donor site of hallux-nail flap of 1 patient was partially necrotic, which was healed completely after 10 days' dressing change. Six weeks after the reconstruction surgery, callus formation was observed in the reconstructed thumb and the second toe of the donor foot of 10 patients, the Kirschner wires were removed; while callus formation of the reconstructed thumb was poor in 2 patients, and the Kirschner wires were removed after 2 weeks of delay. During the follow-up of 6 to 24 months, the shape of reconstructed thumb was similar to that of the healthy thumb, the discrimination distance between the two points of the reconstructed thumb was 7 to 11 mm, and the functional evaluation results were excellent in 4 cases, good in 6 cases, and fair in 2 cases. The interphalangeal joints of the hallux and the second toe of the donor foot were stiff, mild scar hyperplasia was left in the donor site of foot, and the standing and walking functions of the donor foot were not significantly limited. Conclusions: The application of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns adopts the concept of reconstruction instead of repair to close the wound. It can restore the shape and function of the damaged thumb without causing great damage to the donor foot.

Acromioclavicular joint (ACJ) injury is a common shoulder injury. There are various techniques of ACJ reconstruction. Superficial infection after ACJ reconstruction is not an uncommon complication. However, osteomyelitis post ACJ reconstruction has never been highlighted as a possible complication. Our patient is a 31-year-old male who sustained a Rockwood 5 ACJ dislocation and had anatomical ACJ reconstruction with autogenous gracilis and semitendinosus graft. Our technique involved the anatomical reconstruction of the ACJ and the coracoclavicular ligament with the usage of two bioscrews and the temporary stabilisation of the ACJ with two k-wires. As in any orthopaedic surgery, infection is often disastrous especially when the surgery involves implants. It can be disastrous with high morbidity to the patient as well as a costly complication to treat. Therefore, we wish to highlight this case as despite its rarity, osteomyelitis can be devastating to the patient and should be prevented if possible.
