The application of pedicle orbital fat flap for the correction of lacrimal groove and palpebromalar groove deformity in the middle-aged and old people

目的探讨中老年人泪槽和睑颊沟畸形的整复方法。方法1996至2011年，采用经皮眶脂肪释放、带蒂眶脂肪瓣充填的方法矫正中老年泪槽畸形伴或不伴睑颊沟畸形426例，其中初次手术者372例，二次手术者54例。362例术后获得3—24个月的随访观察。结果362例随访者中，283例泪槽和睑颊沟畸形完全矫正，79例畸形明显改善；2例二次手术者，由于术前有严重的下睑凹陷，泪槽畸形纠正不满意。结论经皮眶脂肪释放，带蒂眶脂肪瓣充填的方法，可以有效矫正中老年人泪槽和睑颊沟畸形。

Objective To explore the effective techniques for correction of lacrimal groove and palpebromalar groove deformity in the middle-aged and old people. Method The lacrimal groove and palpebromalar groove deformity was corrected by the techniques of transcutaneous orbital fat releasing and pedicle orbital fat flap filling. From 1996 to 2011, 426 patients, aged from 35 to 72 （ average, 48 ） , were treated by the techniques. Among them, 54 patients had underwent the surgical treatment before this operation. 362 patients were followed up for 3-24 months. Results Completely correction was achieved in 283 patients, obvious improvement in 79 patients. The result was not satisfied in 2 patients with severe deformity who had surgical treatment before. Conclusion The lacrimal groove and palpebromalar groove deformity can be effectively corrected by transcutaneous orbital fat releasing and pedicle orbital fat flap in the middle-aged and old people.
