Individualized design of facial artery perforator flap for reconstruction of soft tissue defects in the midface / 中华医学美学美容杂志

Objective@#To explore the clinical application of individualized design of facial artery perforator flap for the repair of midfacial defect caused by tumor resection.@*Methods@#From January 2015 to January 2018, a total of 36 cases of midfacial defect were repaired by individualized designed facial artery. Flaps were designed and harvested according to the location and size of the midfacial defect resulted from tumor resection, including propeller flaps, droplet flaps and swallowtail-shape flaps. Flap size was between 1.3 cm × 1.6 cm and 2.0 cm × 4.2 cm with the donor site being sutured in the first stage.@*Results@#During the 6 months to 3 years of postoperative follow-up, no tumor recurred. All the 36 cases of individualized designed facial artery perforator flaps survived well. Furthermore, flaps being designed according to the wound defect had a good appearance, the flaps matched the color and texture of the surrounding skin and had a favorable appearance. Besides, flaps had a certain degree of sensory recovery while there was no obvious scarring presented in the donor area.@*Conclusions@#Individualized design of facial artery perforator flap has great advantages of simple and flexible, easy manipulation, reliable flap blood flow and minimal donor injury, which render it valuable for clinical application.

Long-term efficacy of intense pulsed light on epilation / 中华医学美学美容杂志

Objective To evaluate the long-term effects and safety of an intense pulsed light (IPL) in the treatment of epilation.Methods 159 patients received treatment with a non-coherent IPL because of unwanted facial and body hair.116 cases were followed up by means of phone call or letters.The average follow-up time was 38 months.Results Overall,36 (31.0％) patients were very satisfied,53 (45.7％) were satisfied and 27 (23.3％) remained unsatisfied with the outcome of lightassisted hair removal.The non-coherent intense pulsed light satisfactorily removed unwanted dark hair.Hair-free periods from weeks to years could be observed.Besides,the satisfaction was not related with the colour of the skin.Conclusions Hair removal by a non-coherent intense pulsed light is an effective and safe method for long-term epilation of unwanted hair.

Clinical evaluation of spontaneous rupture of the finger extensors / 中国矫形外科杂志

[Objective]To investigate the etiology,pathological characteristic and therapeutic effect of spontaneous rupture of the finger extensors.[Method]Twelve patients were included in this research group.Eight cases were diagnosed as spontaneous rupture of the extensor pollicis long(EPL) and were repaired by transfer of the extensor indicis proprius(EIP).Three cases were spontaneous double rupture of the the ring and small finger extensors.The distal stump of the ring finger extensor was woven into the middle finger extensor and the EIP was transferred to reconstruct the extensor digiti quinti.There was one case of spontaneous triple rupture of the the middle,ring finger and small finger extensors.Transplantation of frozen allogenic extensors was utilized.[Result]The finger extensor rupture occurred after either rheumatic arthritis or distal radius fracture.The former pathological examination showed that the tenosynovitis and chronic inflammation of tendons accompanying with localized necrosis was dominant,while tendon fiber rupture played an important role in the latter.All patients achieved 100% of good results and no recurrent rupture occurred.[Conclusion]The inflammation invasion or attrition in the fracture site was a patological basis to cause spontaneous rupture of finger extensors.The EPI transposition was a reliable option to reconstruct the EPL.It is suggested that allogenic tendon transplantation be applied in the case of multiple ruptures of the extensor tendons.

Combined transplantation using frozen allogenic composite tissues of finger and autogenous second toe / 中华显微外科杂志

Objective To investigate the clinical result of reconstructed thumbs and fingers using frozen allogeneic composite tissues of fingers and autogenous toe Methods Fifty thumbs and fingers were reconstructed in 24 patients (25 hands) by allogeneic composite tissues of finger wrappoed by free neurovascular big toe nail skin flap and combined transplantation with autogenous second toe 15 patients were followed up for 4 years in average with examination in the ambulant clinic, communication and X ray photography to evaluate the clinical effect Results Recovered sensory function of the reconstructed fingers as well as good opposition function were seen There were Charcot's like arthrosis of allogeneic MP and arthroclisisof IP in 2 cases The postoperative gait of the doner's feet was normal The site of grafted skin on big toe was rubbed easily in 4 cases and the valgus hallexo of the doner's foot were seen in 3 cases, the plantaris callus in 2 cases Postoperative immunological rejection didn't elicit The junction between implanted allo phalangen tendon and autophalanges tendon were reliably healed Conclusions This operation gives reconstructed more fingers without sacrificing more toes for patients The walking function of donor foot is good The antigenicity of allogeneic grafts could be abated after preservation under 30℃ or frozen dried
