OBJECTIVE: To investigate the effectiveness of Flow-through bridge anterolateral thigh flap transplantation in the treatment of complex calf soft tissue defects. METHODS: The clinical data of the patients with complicated calf soft tissue defects, who were treated with Flow-through bridge anterolateral thigh flap (study group, 23 cases) or bridge anterolateral thigh flap (control group, 23 cases) between January 2008 and January 2022, were retrospectively analyzed. All complex calf soft tissue defects in the two groups were caused by trauma or osteomyelitis, and there was only one major blood vessel in the calf or no blood vessel anastomosed with the grafted skin flap. There was no significant difference between the two groups in general data such as gender, age, etiology, size of leg soft tissue defect, and time from injury to operation ( P>0.05). The lower extremity functional scale (LEFS) was used to evaluate the sufferred lower extremity function of the both groups after operation, and the peripheral blood circulation score of the healthy side was evaluated according to the Chinese Medical Association Hand Surgery Society's functional evaluation standard for replantation of amputated limbs. Weber's quantitative method was used to detect static 2-point discrimination (S2PD) to evaluate peripheral sensation of the healthy side, and the popliteal artery flow velocity, toenail capillary filling time, foot temperature, toe blood oxygen saturation of the healthy side, and the incidence of complications were compared between the two groups. RESULTS: No vascular or nerve injury occurred during operation. All flaps survived, and 1 case of partial flap necrosis occurred in both groups, which healed after free skin grafting. All patients were followed up 6 months to 8 years, with a median time of 26 months. The function of the sufferred limb of the two groups recovered satisfactorily, the blood supply of the flap was good, the texture was soft, and the appearance was fair. The incision in the donor site healed well with a linear scar, and the color of the skin graft area was similar. Only a rectangular scar could be seen in the skin donor area where have a satisfactory appearance. The blood supply of the distal limb of the healthy limb was good, and there was no obvious abnormality in color and skin temperature, and the blood supply of the limb was normal during activity. The popliteal artery flow velocity in the study group was significantly faster than that in the control group at 1 month after the pedicle was cut, and the foot temperature, toe blood oxygen saturation, S2PD, toenail capillary filling time, and peripheral blood circulation score were significantly better than those in the control group ( P<0.05). There were 8 cases of cold feet and 2 cases of numbness on the healthy side in the control group, while only 3 cases of cold feet occurred in the study group. The incidence of complications in the study group (13.04%) was significantly lower than that in the control group (43.47%) ( χ ²=3.860, P=0.049). There was no significant difference in LEFS score between the two groups at 6 months after operation ( P>0.05). CONCLUSION Flow-through bridge anterolateral thigh flap can reduce postoperative complications of healthy feet and reduce the impact of surgery on blood supply and sensation of healthy feet. It is an effective method for repairing complex calf soft tissue defects.

OBJECTIVE: To investigate the short-term effectiveness of transverse antecubital incision in the treatment of failed closed reduction of Gartland type Ⅲ supracondylar humeral fractures (SHFs) in children. METHODS: Between July 2020 and April 2022, 20 children with Gartland type Ⅲ SHFs who failed in closed reduction were treated with internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision. There were 9 boys and 11 girls with an average age of 3.1 years (range, 1.1-6.0 years). The causes of injuries were fall in 12 cases and fall from height in 8 cases. The time from admission to operation ranged from 7 to 18 hours, with an average of 12.4 hours. The healing of the incision and the occurrence of complications such as nerve injury and cubitus varus were observed after operation; the elbow flexion and extension range of motion after removing the gypsum, after removing the Kirschner wire, and at last follow-up were recorded and compared, as well as the elbow flexion and extension and forearm rotation range of motion at last follow-up between healthy and affected sides; the Baumann angle was measured on the X-ray film, and the fracture healing was observed. At last follow-up, the effectiveness was evaluated according to the Flynn elbow function evaluation criteria. RESULTS: All incisions healed by first intention, and there was no skin necrosis, scar contracture, ulnar nerve injury, and cubitus varus. Postoperative pain occurred in the radial-dorsal thumb in 2 cases. The gypsum was removed and elbow flexion and extension exercises were started at 2-4 weeks (mean, 2.7 weeks) after operation, and the Kirschner wire was removed at 4-5 weeks (mean, 4.3 weeks). All the 20 patients were followed up 6-16 months, with an average of 12.4 months. The fracture healing time was 4-5 weeks, with an average of 4.5 weeks, and there was no complication such as delayed healing and myositis ossificans. The flexion and extension range of motion of the elbow joint gradually improved after operation, and there were significant differences between the time after removing the gypsum, after removing the Kirschner wire, and at last follow-up ( P<0.017). There was no significant difference in the flexion and extension of the elbow joint and the forearm rotation range of motion between the healthy and affected sides at last follow-up ( P>0.05). There was no significant difference in Baumann angle between the time of immediate after operation, after removing the Kirschner wire, and at last follow-up ( P>0.05). According to Flynn elbow function evaluation standard, 16 cases were excellent and 4 cases were good, the excellent and good rate was 100%. CONCLUSION The treatment of Gartland type Ⅲ SHFs in children with failed closed reduction by internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision has the advantages of complete soft tissue hinge behind the fracture for easy reduction and wire fixation, small incision, less complications, fast fracture healing, early functional recovery, reliable reduction and fixation, and can obtain satisfactory results.

OBJECTIVE: To explore the effectiveness of folded transverse superficial epigastric artery perforator flap in repairing the large penetrating defect after buccal carcinoma resection. METHODS: Between January 2019 and June 2021, 12 patients with buccal squamous cell carcinoma were treated. There were 6 males and 6 females with an average of 66.9 years (range, 53-79 years). The pathological stage was T3a-T4b, and the preoperative mouth opening was (3.08±0.46) cm. The disease duration ranged from 6 to 24 months, with an average of 15 months. After buccal carcinoma radical resection and neck lymph node dissection, the penetrating defects in size of 8 cm×6 cm to 16 cm×8 cm and in depth of 0.5-1.5 cm were remained. The transverse superficial epigastric artery perforator flap in size of 8 cm×6 cm to 14 cm×8 cm were harvested and folded to repair the penetrating defects. The donor site was sutured directly. RESULTS: All 12 skin flaps survived after operation, and the wounds healed by first intention. No internal or external fistula complications occurred. All incisions at the recipient site healed by first intention. All patients were followed up 12-18 months (mean, 14 months). There was no obvious abnormality in the color and texture of the flap, the oral and facial appearances were symmetrical, and there was no obvious swelling in the cheek. At last follow-up, the patient's mouth opening was (2.89±0.33) cm, which was not significantly different from that before operation ( t=1.879, P=0.087). The subjective satisfaction scores of 12 patients were 6-8 points, with an average of 7.3 points. Significant scars remained at the donor site but concealed in location. CONCLUSION The folded transverse superficial epigastric artery perforator flap can be used as a surgical method for repairing large penetrating defects after the buccal carcinoma resection, with a good recovery of facial appearance and oral function.

OBJECTIVE: To investigate the effectiveness of joystick technique assisted closed reduction and cannulated screw fixation in the treatment of femoral neck fracture. METHODS: Seventy-four patients with fresh femoral neck fractures who met the selection criteria between April 2017 and December 2018 were selected and divided into observation group (36 cases with closed reduction assisted by joystick technique) and control group (38 cases with closed manual reduction). There was no significant difference in gender, age, fracture side, cause of injury, Garden classification, Pauwels classification, time from injury to operation, and complications (except for hypertension) between the two groups ( P>0.05). The operation time, intraoperative infusion volume, complications, and femoral neck shortening were recorded and compared between the two groups. Garden reduction index was used to evaluate the effect of fracture reduction, and score of fracture reduction (SFR) was designed and was used to evaluate the subtle reduction effect of joystick technique. RESULTS: The operation was successfully completed in both groups. There was no significant difference in operation time and intraoperative infusion volume between the two groups ( P>0.05). All patients were followed up 17-38 months, with an average of 27.7 months. Two patients in the observation group received joint replacement due to failure of internal fixation during the follow-up, and the other patients had fracture healing. Within 1 week after operation, the Garden reduxtion index of the observation group was better than the control group; the SFR score of the observation group was also higher than that of the control group; the proportion of femoral neck shortening within 1 week after operation and at 1 year after operation in the observation group were lower than those in the control group. The differences of the above indexes between the two groups were significant ( P<0.05). CONCLUSION The joystick technique can improve the effectiveness of closed reduction of femoral neck fractures and reduce the incidence of femoral neck shortening. The designed SFR score can directly and objectively evaluate the reduction effect of femoral neck fracture.

OBJECTIVE: To evaluate the effectiveness of neurovascular staghorn flap for repairing defects in fingertips. METHODS: Between August 2019 and October 2021, a total of 15 fingertips defects were repaired with neurovascular staghorn flap. There were 8 males and 7 females with an average age of 44 years (range, 28-65 years). The causes of injury included 8 cases of machine crush injury, 4 cases of heavy object crush injury, and 3 cases of cutting injury. There were 1 case of thumb, 5 cases of index finger, 6 cases of middle finger, 2 cases of ring finger, and 1 case of little finger. There were 12 cases in emergency, and 3 cases with finger tip necrosis after trauma suture. Bone and tendon exposed in all cases. The range of fingertip defect was 1.2 cm×0.8 cm to 1.8 cm×1.5 cm, and the range of skin flap was 2.0 cm×1.5 cm to 2.5 cm×2.0 cm. The donor site was sutured directly. RESULTS: All flaps survived without infection or necrosis, and the incisions healed by first intention. All patients were followed up 6-12 months, with an average of 10 months. At last follow-up, the appearance of the flap was satisfactory, the wear resistance was good, the color was similar to the skin of the finger pulp, and there was no swelling; the two-point discrimination of the flap was 3-5 mm. One patient had linear scar contracture on the palmar side with slight limitation of flexion and extension, which had little effect on the function; the other patients had no obvious scar contracture, good flexion and extension of the fingers, and no dysfunction. The finger function was evaluated according to the total range of motion (TAM) system of the Hand Surgery Society of Chinese Medical Association, and excellent results were obtained in 13 cases and good results in 2 cases. CONCLUSION The neurovascular staghorn flap is a simple and reliable method to repair fingertip defect. The flap has a good fit with the wound without wasting skin. The appearance and function of the finger are satisfactory after operation.

Complex ventral hernia refers to a large hernia that is complicated by a series of concurrent conditions. Change in intra-abdominal pressure is one of the main pathways through which various factors exert an impact on perioperative risk and postoperative recurrence. Taking abdominal pressure reconstruction as the core, the treatment strategy for complex abdominal hernia can be formulated from three aspects: improving patients' tolerance, expanding abdominal cavity volume, and reducing the volume of abdominal contents. Improving patients' tolerance includes abdominal wall compliance training and progressive preoperative pneumoperitoneum. To expand the volume of the abdominal cavity, implanting hernia repair materials, component separation technique, autologous tissue transplantation, component expend technique, and chemical component separation can be used. Initiative content reduction surgery and temporary abdominal closure may be performed to reduce the volume of abdominal contents. For different cases of complex ventral hernia, personalized treatment measures can be safely and feasibly adopted depending on the condition of the patients and the intra-abdominal pressure situation.

Objective: To evaluate the efficacy of supraclavicular fasciocutaneous island flap (SIF) for repairing the defect of parotid or auricle regions after tumor resection. Methods: From February 2019 to June 2021, 12 patients (11 males and 1 female, aged 54-77 years old), of whom 4 with parotid adenoid cystic carcinoma and 8 with auricular basal cell carcinoma underwent reconstruction surgery for postoperative defects in the parotid gland area and auricular area with SIF in the Department of Otorhinolaryngology Head and Neck Surgery, the Second Xiangya Hospital of Central South University and their clinical data were retrospectively analyzed. Size of the SIF, time for harvesting SIF, neck lymph node dissection and postoperative complications were recorded. Results: The flap areas were (6-9) cm × (8-13) cm, and the harvesting time for SIF ranged from 40 to 80 min, averaging 51.7 min. The donor sites were directly closed. All patients underwent ipsilateral levels Ⅰ-Ⅲ neck dissection, with 4 cases undergoing additional level Ⅳ neck dissection and 2 cases undergoing level Ⅳ-Ⅴ neck dissection. Of the 12 SIF, 10 were completely survival and 2 had flap arterial crisis with partial flap necrosis, in addition, 1 had donor site wound dehiscence. With follow-up of 10-42 months, there were no tumor recurrences in 10 patients, 1 patient was lost to follow-up at 10 months postoperatively, and 1 patient experienced local tumor recurrence at 11 months after surgery and died 15 months later. Conclusion: SIF is an easily harvested flap with good skin features matching the skin in parotid and auricle regions and less damage to donor site, and this flap has no need for microvascular anastomosis technique. SIF is feasible and effective for repairing defects in parotid and auricle area.

Objective: To investigate the feasibility of only surgical resection for nasal vestibular squamous cell carcinoma and the efficacy of perforator flap of ipsilateral nasolabial sulcus in repairing postoperative defects. Methods: The clinical data of 8 cases with squamous cell carcinoma of the nasal vestibule who admitted to Department of Facial Plastic and Reconstructive Surgery, Eye & ENT Hospital, Fudan University were analyzed, including 6 males and 2 females, aged from 38 to 75 years. The tumor of the nasal vestibule was eradicated in time after making definite diagnosis of lesions, then the perforators flap of the ipsilateral nasolabial sulcus was used for repairment, without performing further chemotherapy or radiotherapy after surgery. The tumor recurrence, facial appearance, nostril form, donor area scar, nasal ventilation function, and cutaneous sensation were evaluated after surgery. Descriptive analysis was used in this research. Results: There were 2 cases of stage T1 and 6 cases of stage T2 in 8 cases. After 32 to 45 months of following-up, no recurrence accurred and all the flaps survived well. However, there was about 2 mm necrosis of the transplanted flap in the lateral foot of the alar in one case, which was healed well by carrying out wound care after 10 d. And the dark color flap was occurred in another case, showing the flap's backflow trouble, yet it was improved with addressing timely during 5 d postoperation. Pincusion-like deformity of the transplanted flap occurred in 4 cases (50%), which subsided gradually after 6 months. The morphology of the anterior nostril was altered in 4 cases (50%), but there was no ventilation trouble and no need for addressment in any case. The postoperative facial appearance was rated as excellentor good with hidden scar in the donor site, and the sensation of the transplanted flaps was indistinct from the surrounding tissue after 3 months. Conclusions: Surgical resection of nasal vestibular squamous cell carcinoma with tumor stage T1-2 is a feasible treatment. And it is the one of the best reconstructive methods of the perforator flap of the ipsilateral nasolabial sulcus to repair the deformities after the surgery.

In the field of plastic and reconstructive surgery, the loss of organs or tissues caused by diseases or injuries has resulted in challenges, such as donor shortage and immunosuppression. In recent years, with the development of regenerative medicine, the decellularization-recellularization strategy seems to be a promising and attractive method to resolve these difficulties. The decellularized extracellular matrix contains no cells and genetic materials, while retaining the complex ultrastructure, and it can be used as a scaffold for cell seeding and subsequent transplantation, thereby promoting the regeneration of diseased or damaged tissues and organs. This review provided an overview of decellularization-recellularization technique, and mainly concentrated on the application of decellularization-recellularization technique in the field of plastic and reconstructive surgery, including the remodeling of skin, nose, ears, face, and limbs. Finally, we proposed the challenges in and the direction of future development of decellularization-recellularization technique in plastic surgery.

OBJECTIVE: To conduct anatomical study on the iliac crest chimeric tissue flap and summarize its effectiveness of clinical application in repairing limb wounds. METHODS: Latex perfusion and anatomical study were performed on 6 fresh adult cadaver specimens with 12 sides, to observe the initial location, distribution, quantity, and direction of the common circumflexa iliac artery, the deep circumflexa iliac artery, and the superficial circumflexa iliac artery, and to measure their initial external diameter. Between December 2020 and September 2022, the iliac crest chimeric tissue flap repair was performed on 5 patients with soft tissue of limbs and bone defects. There were 3 males and 2 females, with an average age of 46 years (range, 23-60 years). Among them, there were 3 cases of radii and skin soft tissue defects and 2 cases of tibia and skin soft tissue defects. The length of bone defects was 4-8 cm and the area of skin soft tissue defects ranged from 9 cm×5 cm to 15 cm×6 cm. The length of the iliac flap was 4-8 cm and the area of skin flap ranged from 12.0 cm×5.5 cm to 16.0 cm×8.0 cm. The donor sites were directly sutured. RESULTS: Anatomical studies showed that there were 10 common circumflex iliac arteries in 5 specimens, which originated from the lateral or posterolateral side of the transition between the external iliac artery and the femoral artery, with a length of 1.2-1.6 cm and an initial external diameter of 0.8-1.4 mm. In 1 specimen without common circumflexa iliac artery, the superficial and deep circumflex iliac arteries originated from the external iliac artery and the femoral artery, respectively, while the rest originated from the common circumflex iliac artery. The length of superficial circumflex iliac artery was 4.6-6.7 cm, and the initial external diameter was 0.4-0.8 mm. There were 3-6 perforator vessels along the way. The length of deep circumflex iliac artery was 7.8-9.2 cm, and the initial external diameter was 0.5-0.7 mm. There were 3-5 muscular branches, 4-6 periosteal branches, and 2-3 musculocutaneous branches along the way. Based on the anatomical observation results, all iliac crest chimeric tissue flaps were successfully resected and survived after operation. The wounds at recipient and donor sites healed by first intention. All patients were followed up 8-24 months, with an average of 12 months. The tissue flap has good appearance and soft texture. X-ray film reexamination showed that all the osteotomy healed, and no obvious bone resorption was observed during follow-up. CONCLUSION The common circumflex iliac artery, deep circumflex iliac artery, and superficial circumflex iliac artery were anatomically constant, and it was safe and reliable to use iliac crest chimeric tissue flap in repairing the soft tissue and bone defects of limbs.
