OBJECTIVE:
To investigate the clinical application of high-frequency color Doppler ultrasound (HFCDU) in detecting perforators in the deep adipose layers for harvesting super-thin anterolateral thigh flap (ALTF).
METHODS:
Between August 2019 and January 2023, 45 patients (46 sides) with skin and soft tissue defects in the foot and ankle were treated, including 29 males and 16 females, aged from 22 to 62 years, with an average of 46.7 years. The body mass index ranged from 19.6 to 36.2 kg/m 2, with an average of 23.62 kg/m 2. The causes of injury included traffic accident injury in 15 cases, heavy object crush injury in 20 cases, mechanical injury in 8 cases, heat crush injury in 1 case, and chronic infection in 1 case. There were 20 cases on the left side, 24 cases on the right side, and 1 case on both sides. After thorough debridement, the wound size ranged from 5 cm×4 cm to 17 cm×11 cm. All patients underwent free super-thin ALTF transplantation repair. HFCDU was used to detect the location of the perforators piercing the deep and superficial fascia, as well as the direction and branches of the perforators within the deep adipose layers before operation. According to the preoperative HFCDU findings, the dimensions of the super-thin ALTF ranged from 6 cm×4 cm to 18 cm×12 cm. The donor sites of the flaps were directly sutured.
RESULTS:
A total of 55 perforators were detected by HFCDU before operation, but 1 was not found during operation. During operation, a total of 56 perforators were found, and 2 perforators were not detected by HFCDU. The positive predictive value of HFCDU for identifying perforator vessels was 98.2%, and the sensitivity was 96.4%. Among the 54 perforators accurately located by HFCDU, the orientation of the perforators in the deep adipose layers was confirmed during operation. There were 21 perforators (38.9%) traveled laterally and inferiorly, 12 (22.2%) traveled medially and inferiorly, 14 (25.9%) traveled laterally and superiorly, 5 (9.3%) traveled medially and superiorly, and 2 (3.7%) ran almost vertically to the body surface. Among the 54 perforators accurately located by HFCDU, 35 were identified as type 1 perforators and 12 as type 2 perforators (HFCDU misidentified 7 type 2 perforators as type 1 perforators). The sensitivity of HFCDU in identifying type 1 perforators was 100%, with a positive predictive value of 83.3%. For type 2 perforators, the sensitivity was 63.2%, and the positive predictive value was 100%. The surgeries were successfully completed. The super-thin ALTF had a thickness ranging from 2 to 6 mm, with an average of 3.56 mm. All super-thin ALTF survived, however, 1 flap experienced a venous crisis at 1 day after operation, but it survived after emergency exploration and re-anastomosis of the veins; 1 flap developed venous crisis at 3 days after operation but survived after bleeding with several small incisions; 3 flaps had necrosis at the distal edge of the epidermis, which healed after undergoing dressing changes. All 45 patients were followed up 6-18 months (mean, 13.6 months). Three flaps required secondary defatting procedures, while the rest had the appropriate thickness, and the overall appearance was satisfactory.
CONCLUSION
Preoperative application of HFCDU to detect the perforator in the deep adipose layers can improve the success and safety of the procedure by facilitating the harvest of super-thin ALTF.

OBJECTIVE:
To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back.
METHODS:
Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage.
RESULTS:
All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients' daily life were not affected, and linear scar was left in the donor site.
CONCLUSION
The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.

OBJECTIVE:
To summarize the effectiveness of the temporal island flap pedicled with the perforating branch of zygomatic orbital artery for repairing defects after periocular malignant tumor resection.
METHODS:
Between January 2015 and December 2020, 15 patients with periocular malignant tumors were treated. There were 5 males and 10 females with an average age of 62 years (range, 40-75 years). There were 12 cases of basal cell carcinoma and 3 cases of squamous carcinoma. The disease duration ranged from 5 months to 10 years (median, 2 years). The size of tumors ranged from 1.0 cm×0.8 cm to 2.5 cm×1.5 cm, without tarsal plate invasion. After extensive resection of the tumors, the left defects in size of 2.0 cm×1.5 cm to 3.5 cm×2.0 cm were repaired with the temporal island flap pedicled with the perforating branch of zygomatic orbital artery via subcutaneous tunnel. The size of the flaps ranged from 3.0 cm×1.5 cm to 5.0 cm×2.0 cm. The donor sites were separated subcutaneously and sutured directly.
RESULTS:
All flaps survived after operation and the wounds healed by first intention. The incisions at donor sites healed by first intention. All patients were followed up 6-24 months (median, 11 months). The flaps were not obviously bloated, the texture and color were basically the same as the surrounding normal skin, and the scars at recipient sites were not obviously. There was no complication such as ptosis, ectropion, or incomplete closure of the eyelids and recurrence of tumor during follow-up.
CONCLUSION
The temporal island flap pedicled with the perforating branch of zygomatic orbital artery can repair the defects after periorbital malignant tumors resection and has the advantages of reliable blood supply, flexible design, and good morphology and function.

Objective To compare the image quality of three high-resolution dynamic MRI methods for evaluating the motion of temporomandibular joint disc and condyle. Methods Twenty-five patients with suspected temporomandibular joint disorders were examined by single-shot fast spin-echo (SSFSE),fast imaging employing steady-state acquisition (FIESTA),and spoiled gradient echo (SPGR) on the oblique sagittal position.Two radiologists performed subjective and objective evaluation on the images with double-blind method.The subjective evaluation included the signal intensity of mandibular condyle,articular disc,soft tissue around articular disc,and lateral pterygoid muscle,the contrast between articular disc and condyle,the contrast between articular disc and surrounding soft tissue,condylar motion,and disc movement.The objective evaluation indexes included image signal intensity,signal-to-noise ratio (SNR),and contrast-to-noise ratio (CNR).The subjective and objective indexes of the image quality were compared between the three sequences. Results The SSFSE sequence had lower signal intensity of articular disc and higher signal intensity of condyle and surrounding soft tissue than FIESTA and SPGR sequences (all P<0.001).The SPGR sequence showed higher signal intensity of lateral pterygoid muscle than the SSFSE and FIESTA sequences (P=0.017,P<0.001).Among the three sequences,SSFSE sequence showed the clearest articular disc structure (χ2=41.952,P<0.001),the strongest contrast between articular disc and condyle (χ2=35.379,P<0.001),the strongest contrast between articular disc and surrounding soft tissue (χ2=27.324,P<0.001),and the clearest movement of articular disc (χ2=44.655,P<0.001).SSFSE and FIESTA sequences showed higher proportion of disc displacement and reduction than SPGR sequence (all P<0.001).The CNR (χ2=21.400,P<0.001),SNR (χ2=34.880,P<0.001),and condyle signal intensity (F=337.151,P<0.001) demonstrated differences among SSFSE,FIESTA,and SPGR sequences.The CNR of SSFSE sequence was higher than that of FIESTA sequence (P<0.001),while it had no significant difference between SSFSE and SPGR sequences (P=0.472).In addition,the SSFSE sequence had higher SNR and signal intensity than FIESTA and SPGR sequences (all P<0.001). Conclusion The best image quality can be observed from SSFSE sequence where both the structure and movement of temporomandibular joint are well displayed.Therefore,SSFSE is preferred for the examination of temporomandibular joint movement.

Chinese Journal of Traumatology 2023;26(1):60-62
Post-burn contractures are common entities seen in developing countries. There are multiple reasons for the development of contractures, most are preventable. In extensive contractures, a strategic plan is necessary to release all contractures and yet not antagonize post-operative positions. It is also necessary to be cost-effective and minimize the number of surgeries needed. Conventionally the release sequence in extensive burn contractures is proximal to distal. In this case report, we discuss an unusual sequence where we released distal contractures before the proximal to achieve optimum results. A 3-year-old child with post-burn contracture of hand, wrist, elbow, and axilla was treated in 2 stages, with the release of wrist contracture and cover with pedicled abdominal flap in the first stage and division of pedicled flap with the release of axilla and elbow contracture in the second stage. Thus, the release of all contractures was achieved without antagonizing post-operative positions and minimized the number of surgeries. A case-based approach may be crucial in making a strategic surgical plan to minimize the rehabilitation phase, rather than following known dictums.

Objective: To explore the clinical effects of island posterior femoral composite tissue flaps in the repair of sinus cavity pressure ulcers in the areas of ischial tuberosity and greater trochanter. Methods: The retrospective observational study was conducted. From December 2018 to December 2021, 23 patients with sinus cavity pressure ulcers in the areas of ischial tuberosity and greater trochanter who met the inclusion criteria were admitted to Ganzhou People's Hospital, including 16 males and 7 females, aged 45 to 86 years. The size of pressure ulcers in ischial tuberosity ranged from 1.5 cm×1.0 cm to 8.0 cm×5.0 cm, and the size of pressure ulcers in greater trochanter ranged from 4.0 cm×3.0 cm to 20.0 cm×10.0 cm before debridement. After treatment of underlying diseases, debridement and vacuum sealing drainage for 5 to 14 days were performed. All the wounds were repaired by island posterior femoral composite tissue flaps, with area of 4.5 cm×3.0 cm-24.0 cm×12.0 cm, pedicle width of 3-5 cm, pedicle length of 5-8 cm, and rotation radius of 30-40 cm. Most of the donor site wounds were sutured directly, and only 4 donor site wounds were repaired by intermediate thickness skin graft from the contralateral thigh. The survival of composite tissue flaps, wound healing of the donor and recipient sites and the complications were observed. The recurrence of pressure ulcers, and the appearance and texture of flaps were observed during follow-up. Results: A total of 32 wounds in 23 patients were repaired by island posterior femoral composite tissue flaps (including 3 fascio subcutaneous flaps, 24 fascial flaps+fascio subcutaneous flaps, 2 fascial flaps+fascial dermal flaps, 2 fascial flaps+fascio subcutaneous flaps+femoral biceps flaps, and one fascial flap+fascio subcutaneous flap+gracilis muscle flap). Among them, 31 composite tissue flaps survived well, and a small portion of necrosis occurred in one fascial flap+fascio subcutaneous flap post surgery. The survival rate of composite tissue flap post surgery was 96.9% (31/32). Twenty-nine wounds in the recipient sites were healed, and 2 wounds were torn at the flap pedicle due to improper postural changes, and healed one week after bedside debridement. One wound was partially necrotic due to the flap bruising, and healed 10 days after re-debridement. Thirty-one wounds in the donor sites (including 4 skin graft areas) were healed, and one wound in the donor site was torn due to improper handling at discharge, and healed 15 days after re-debridement and suture. The complication rate was 12.5% (4/32), mainly the incision dehiscence of the flap pedicle and the donor sites (3 wounds), followed by venous congestion at the distal end of flap (one wound). During the follow-up of 3 to 24 months, the pressure ulcers did not recur and the flaps had good appearance and soft texture. Conclusions: The island posterior femoral composite tissue flaps has good blood circulation, large rotation radius, and sufficient tissue volume. It has a high survival rate, good wound healing, low skin grafting rate in the donor site, few postoperative complications, and good long-term effect in the repair of sinus cavity pressure ulcers in the areas of ischial tuberosity and greater trochanter.

Objective: To investigate the anatomical classification of adductor magnus perforator flap and its application in head and neck reconstruction. Methods: From January 2017 to January 2020, Hunan Cancer Hospital treated 27 cases of oral tumor patients (15 cases of tongue cancer, 9 cases of gingival cancer and 3 cases of buccal cancer), including 24 males and 3 females, aged 31-56 years old. The course of disease was 1-12 months. Secondary soft tissue defects with the sizes of 5.0 cm × 3.5 cm to 11.0 cm × 8.0 cm were left after radical resection of the tumors, and were repaired with free adductor magnus perforator flaps. The flaps based on the origing locations of perforator vessels were divided into three categories: ① intramuscular perforator: vessel originated between the gracilis muscle and the adductor magnus or passed through a few adductor magnus muscles; ② adductor magnus middle layer perforator: vessel run between the deep and superficial layers of adductor magnus; ③ adductor magnus deep layer perforator: vessel run between the deep layer of adductor magnus and the semimembranous muscle. Descriptive analysis was used in this research. Results: Perforator vessels of adductor magnus were found in all cases, with a total of 62 perforator branches of adductor magnus. The anatomical classification of the perforator vessels was as follows: 12 branches for class ①, 31 branches for class ② and 19 branches for class ③. The vascular pedicles of the free adductor major perforator flaps included type ① for 3 cases, type ② for 16 cases and type ③ for 8 cases. All 27 flaps survived and the donor sites were closed directly. In 18 cases, the perforator arteries and the venae comitan were respectively anastomosed with the superior thyroid arteries and veins. In 9 cases, the pedicle arteries and the venae comitan were respectively anastomosed with the facial arteries and veins. Follow up for 12-40 months showed that the appearances of the flaps and the swallowing and language functions of patients were satisfactory, apart from linear scars were left in the donor sites with no significant affect on the functions of thigh. Local recurrence occurred in 3 cases and radical surgeries were performed again followed by repairs with pedicled pectoralis major myocutaneous flaps. Cervical lymph node metastasis occurred in 2 cases and cervical lymph node dissection was performed again. Conclusions: The adductor magnus perforator flap has soft texture, constant perforator vessel anatomy, flexible donor location and harvesting forms, and less damage to the donor site. It is an ideal choice for postoperative reconstruction in head and neck tumors.

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.

10.Dental implant treatment in vascularized bone flaps after jaw reconstruction.
West China Journal of Stomatology 2023;41(2):123-128
Jaw defects caused by various reasons often seriously affect appearance and function. The goal of the treatment of oral and maxillofacial tumors should include the cure of the tumor and the restoration of premorbid function. The development of microsurgery and digital surgery technology has promoted the development of jaw reconstruction with vascularized free bone flap. Good appearance and improved predictability could be obtained with the help of preope-rative visual design. How to rehabilitate occlusal function on the reconstructed jaw and improve the quality of life of patients has become an important research direction. This article discusses the challenge of jaw reconstruction, the selection of vascularized bone flap, the choice of implant timing, the treatment of peri-implant soft tissue, and the influence of radiotherapy on implants after jaw reconstruction.
