摘要
OBJECTIVE: To introduce the applied anatomy of pedicled buccal fat pad (BFP) graft and a series of histological changes in the healing process of BFP as an uncovered pedicled graft. 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.
目的为了解带蒂颊脂垫组织瓣的应用解剖及无覆盖颊脂垫移植愈合过程中组织学变化.方法通过动物实验,对颊脂垫移植后的愈合过程进行了组织学观察,并对临床采用该组织瓣修复口腔内缺损30例进行观察.结果动物实验及临床观察发现,口腔内无覆盖带蒂颊脂垫移植后,在4-8周创面完全上皮化,8～ 10周再生的粘膜变得光滑,呈粉红色,类似于正常口腔粘膜.结论该组织瓣解剖恒定,易获取,供区与受区近,供区隐蔽,不影响外观及功能,为修复口腔内软组织缺损提供了一种好方法.
