球周麻醉在下睑眼袋整复术中的应用

Joint application of retrobulbar block anesthesia and peribulbar tumescent anesthesia in lower blepharoplasty

目的:探讨在眼袋整复术中合理有效地眶脂切除麻醉方法。方法:在打开眶隔或眼睑囊筋膜前,采用不同于眼科的特殊的球周麻醉,既有效的麻醉了下睑眶脂感觉神经,又增加眶脂容积压力,有助于眶隔脂肪的释放切除。结果:观察78例(156眼),其中行皮肤入路者56例,结膜入路者22例。取脂过程中患者疼痛减轻,取脂更为简便。随访6个月～1年,77例未见眼袋复现,1例有轻微复眼袋复现。结论:在眼袋整复术中,采用特殊的球周麻醉方法应用于眶脂切除效果良好。

Objective To introduce an effective anesthesia technique for orbital fat removal in lower blepharoplasty. Methods Before opening orbital septum or capsulopalpebral fascia, with the application of special peribulbar anesthesia differentiated from traditional peribulbar tumescent anesthesia in lower blepharoplasty,the sensory nerve of orbital fat were effective anesthetized,and the volume pressure in orbit rose. Orbital fat could be removal more easily. Results 78 cases （156 eyes） were observed,of which 56 skin incisal cases and 22 transconjunctival cases. The pain when orbital fat were removed was alleviated.And orbital fat removal was facilitated. After 6- 12 months＇follow-up,no eye bag reappeared except 1 case. Conclusions The application of special peribulbar anesthesia in lower blepharoplasty could make orbital fat removal more effective.
