Reconstruction of the thoracic tracheal defects with portions of deepithelialized myocutaneous flaps after resection of a large tumor

Objective： To study the possibility of using portions of deepithelialized myocutaneous flaps to the reconstruction of thoracic tracheal defects after resection of a large tumor. Methods： From June 2007 to June 2012, five cases of defects of the thoracic trachea were reconstructed by applying portions of deepithelialized myocutaneous flaps. The patients were 27-61 years old with 4 male cases and 1 female. The cervical trachea ranged in diameter from 4-8.5 cm with circumferences of approximately 1/3-2/5 of the bronchial circumference. Results： M1 five patients with thoracic tracheal defects after resection of a large tumor were cured of portions of deepithelialized myocutaneous flaps, with no tracheal stricture remaining and vomica successfully eliminated. During the first 1 to 3 months after the operation, bronchoscopy showed that the tracheal lumens were smooth, and the visible skin of the musculocutaneous flaps became gray and exhibited a small amount of white discharge. Conclusions： Despite this being a small series and short follow-up, this thoracic tracheal reconstruction with portions of deepithelialized myocutaneous flaps shows encouraging preliminary results and could be an alternative to other methods for the treatment of carefully selected patients with thoracic tracheal defects.

Experiences of repairing large defect on adominal wall with artificial mesh and myocutaneous flap

Objective： To evaluate the results of repairing large defect on abdominal wall with artificial meshes（expansible polytetrafluoroethylene, e-PTFE and Composix Mesh）. Methods： Four cases with large defect of abdominal wall caused by abdominal wall tumors or injuries were repaired with artificial meshes and myocutaneous flaps. Results： The cases were followed up 7 months to 2.5 years with no complications such as incisional hernia, bowel adhesion and exposure of the prosthetic materials. Conclusion： The combined use of artificial meshes contained e-PTFE and myocutaneous flaps is a reliable and effective method for repairing large defect on abdominal wall.

Repair of stricture of cervical esophagus with platysma myocutaneous flaps

Objective To observe the effect of repairing stricture of the cervical esophagus with platysma myocutaneous flaps.Methods Fifteen patients with stricture of the cervical esophagus were treated by repair with platysma myocutaneous flaps. The causes of stricture included anastomotic stenosis of the cervical esophagus after colon graft transplantation due to esophageal caustic injury (12 patients), anastomotic stenosis after stomach transposition due to resection of the upper esophageal cancer (2), and stricture caused by limited erosive injury of the cervical esophagus (1). The lengths of stricture were about 3.5 -4.5 cm. The stricture was incised longitudinally. The platysma myocutaneous flaps about 4 cm-5 cm×6 cm-7 cm were resected and were transposed to repair the stricture. Results All flaps survived and no death or serious complications occurred after operation. All patients gained normal functions in swallowing food.Conclusion Repairing stricture of the cervical esophagus with platysma myocutaneous flaps is simple, safe and effective.

Nasal sill reconstruction with the Abbe flap after skin cancer resection:A case report

Local flaps are widely known as the best option for partial nasal reconstructions depending on donor tissue laxity,vascularization,and defect shape and size.The nasolabial flap is used more often in the nasal sill.For larger defects,greater tissue mobilization with larger scars or free flaps is required.Historically,the Abbe flap has been used for lip reconstruction in patients with cleft lip deformities.It allows less retraction than other local flaps or skin grafts in patients with large defect sizes and great defect depths.This study reported on the application of the Abbe flap for nasal sill reconstruction on a 71-year-old female patient with nasal sill basal cell carcinoma who had undergone resection surgery with a posterior lip switch operation with satisfactory results.The application of the Abbe flap could be considered in patients with multiple previous surgeries and at risk for necrosis.

Extensive full-thickness eyelid reconstruction with rotation flaps through "subcutaneous tunnel" and palatal mucosal grafts

· AIM: To reconstruct the extensive full-thickness defects of eyelids is a challenge for the plastic surgeon because of their complex anatomy and special functions.This article presents and discusses an improved surgical technique in which the orbicularis oculi myocutaneous flap is rotated through a "subcutaneous tunnel" in conjunction with a palatal mucosal graft employed for lining.·METHODS: Data from 22 eyes with extensive full-thickness eyelid defects from various causes between2009 and 2013 were analyzed in this study. After the different layers of eyelid were separated completely, a temporally based orbicularis oculi myocutaneous flap was designed following fishtail lines and was mobilized,leaving the base of the pedicle intact with a submuscular tissue attachment. The flap was then rotated through a "subcutaneous tunnel" to the defect, and the donor site was closed primarily. Posterior lamellar reconstruction was performed with a mucosal graft harvested from the hard palate.·RESULTS: All the flaps were survived without any healing problems. There was no corneal irritation, flap contraction, or significant donor-site morbidity in the follow-up period. The incision scars were almost invisible.The defects were repaired completely, and the evaluations showed satisfactory function and appearance.·CONCLUSION: This technique is an improved singlestage operation and can be applied to repair large, full-thickness eyelid defects from various causes. With our method, the functional and aesthetic results can be obtained in either the upper or lower eyelids.

Phalloplasty following penectomy for penile cancer

Objective:Penile reconstruction or phalloplasty following penectomy can be offered where the functional penile length is inadequate for a man to void while standing or to have sexual intercourse.Phalloplasty is usually staged due to the complex surgical techniques required.This narrative review describes the technical concepts and summarises the contemporary outcomes following phalloplasty in this challenging cohort.Methods:A retrospective review of the English literature was performed between January 1946 till November 2021.The data were synthesised and complemented by the expert opinion of the authors with 20 years of experience in this field.The flaps are ideally designed with an integrated urethra or alternatively,a further free flap urethroplasty can be offered.Phallo-plasty is further complicated following penectomy by scarring from the previous surgery and the potential loss of structures that would normally be present at the recipient site.Results:There are limited published data with a total of 19 men recorded in the literature.Only the radial artery forearm free flap and anterolateral thigh flap have been described in this cohort of patients.Functional outcomes including standing micturition,sensation in the neo-phallus,and the ability to orgasm are good.Overall quality of life and satisfaction was also good despite the high risk for long-term complications of the neophallus and donor site.Conclusion:Phalloplasty following penectomy requires microsurgical transfer of a free flap or a pedicled flap to reconstruct a neophallus.An erectile device is inserted at a later stage to facilitate sexual intercourse,if desired.Surgical scarring from penectomy and the potential loss of vasculature that would normally be present at the recipient site may further complicate reconstruction.Surgical and functional outcomes are acceptable based on the limited published experience to date.

Quadratus femoris muscle pedicle bone flap transplantation in the treatment of femoral neck fracture for Chinese young and middle-aged patients： A systematic review and meta-analysis

Purpose： To compare the efficacy of quadratus femoris muscle pedicle bone flap transplantation combined with hollow compression screw fixation versus AO hollow compression screw fixation in the treatment of femoral neck fracture for Chinese young and middle-aged patients. Methods： Case-controlled studies （CCTs） were used to compare the two operative methods in the treatment of femoral neck fractures. Data were retrieved from the Cochrane Library, Pubmed Database, CNKI, Chinese Biomedical Database. Wanfang Data published during the period of January 2005 to December 2014. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical Software Revman S.0 was used for data-analysis. Results： Eight articles were included in the meta-analysis. The results showed that there was statistical significance in the rate of fracture healing [OR = 5.43, 95% CI （2.89, 10.20）, p 〈 0.05], the rate of good function of hip joint [OR=5.12, 95% CI （3.21, 8.17）, p 〈 0.05], the rate of femoral head necrosis [OR = 4.21, 95% CI （2.02, 8.76）, p 〈 0.05], the time of fracture healing [WMD = -46.85, 95% CI （-65.13, -28.56）, p 〈 0.05] between the two groups. Conclusions： For the treatment of femoral neck fractures, the transplantation of quadratus femoris muscle pedicle bone flap combined with hollow compression screw; fixation is superior to the AO hollow compression screw fixation in terms of the rate; of fracture healing, the rate of good function of hip joint, the rate of femoral head： necrosis and the time of fracture healing.

Natural History of Seroma Following the Immediate Latissimus Dorsi Flap Method of Breast Reconstruction

Background： The latissimus dorsi （LD） flap procedure remains a popular and useful breast reconstrtlction tool in China and Western countries, and donor site seroma formation is the main complication. This study was conducted in Chinese patients to determine whether stable cases of seromas would resolve without treatment. Methods： A retrospective review of 45 consecutive cases of immediate breast reconstruction with LD flap from April 2012 to February 2017 was conducted. The scope of the seroma was demarcated with a marker pen, and cases that remained stable over time （i.e. the size of the seroma did not increase） were observed without treatment. The measured outcomes included the incidence ofseromas, the volume and duration of postoperative wound drainage, and other demographic characteristics. Results： Twenty-four patients （53.3%） developed a seroma at the donor site. Of these, 21 patients （87.5%） did not require treatment, and the seroma resolved over time. The mean duration of a sustained serol-na was 6.8 ± 1.4 weeks （range： 4-9 weeks）. Conclusions： This study observed the scope and progression of the seromas and found that seromas at the LD donor sites resolved over time without treatnlent.
