METHODS: The healing processes of BFP are demonstrated via uncovered pedicled grafts on rabbits in histological examination. Uncovered buccal fat pads were used to repair soft tissue defects in rabbit oral cavities. RESULTS: The uncovered buccal fat pads showed complete epithelialization of their oral surfaces at 6 to 8 weeks after surgery and were slowly replaced by fibrous tissue. CONCLUSIONS: Advantages of the pedicled buccal fat pad graft include an anatomic region that is consistent and easy to excise. The operation can be performed in one incision, affecting neither appearance nor function of the area. Use of the buccal fat pad provides a good reconstruction of soft tissue defects in the mouth.展开更多

Methods: Twenty-two flap reconstructions were performed to treat soft-tissue defect of 22 patients with open tibial fracture Type IIIB (Gustilo) from 1993 to 1998. The cases were analyzed and discussed retrospectively after follow up of 12-61 months. Results: The size of the flap ranged from 6.6 cm 2 to 28.18 cm 2 and the rate of flap failure was 13.6%. Besides, 3 partial necrosis and 2 postoperative infections occurred in this series. Conclusions: For soft tissue defect of delayed open tibial fracture Type IIIB, flap reconstruction is still an optimal option. The experiences we obtained are ① to design a triangular skin extension or a small Z-plasty over the pedicle to reduce the flap tension; ② to select a unilateral external fixation to provide convenience for any secondary manipulation; and ③ to use serial debridement to diminish flap failure.展开更多
