无覆盖颊脂垫在口腔局部黏膜缺损即刻修复中的应用

Immediate reconstruction of mucous membrane defect with uncovered buccal fat pad

目的 :探讨口腔局部黏膜缺损的修复方法。方法 :采用带蒂无覆盖颊脂垫组织修复 5 0例口腔局部黏膜不同部位缺损 ,其中颊部缺损 2 0例 ,软腭及上后牙槽区缺损 18例 ,磨牙后区缺损 5例 ,口腔上颌窦瘘 5例 ,咽侧缺损 2例。结果 :创口 2～ 3周均I期愈合 ,转移修复无覆盖颊脂垫全部成活 ,4～ 6周完全上皮化。结论 :颊脂垫组织位于口内 ,解剖恒定 ,易于切取 ,供区隐蔽 ,不影响美观及功能 。

Objective:To investigate the reconstruction of mucous membrane defects.Methods:Fifty mucous membrane defects in different parts were repaired with the pedicled uncovered buccal fat pad graft.The defects of 20 cases were in the buccal area,18 cases in the soft palate and posterior-superior alveolar process,5 cases in the molar backside,2 cases in the pharynx and 5 cases in the oroantral fistula.Results:All the uncovered buccal fat pads survived.The wound took about 2-3 weeks to heal and its surface became epithelialiced after 4-6 weeks.Conclusions:As the nocovered buccal fat pad is located in the mouth,it is easy to excise and the operation can be completed by only one incision.It has the advantages of good appearance and minimal functional loss.It is a simply and useful method for immediate reconstruction of local mucous membrane defects.
