Blepharoplasty is one of the most common aesthetic procedures done today. The protruding fat and lid-cheek junction are the most conspicuous signs of aging that need attention. During zygomatic reduction by an intraoral approach we found occasionally that the orbital fat can be exposed through the perforated periosteum at the inferior obital rim. We therefore developed a new blepharoplasty procedure using an oral approach. Seventeen patients aged from 26 to 38 years, of whom six had had a previous unsuccessful blepharoplasty and one had a history of injury to the lower lid, were studied. The operation was done under an infraorbital nerve block and local anaesthesia through an intraoral incision at the upper vestibular groove. The periosteum was raised on the surface of the maxilla to the infraorbital rim, and the infraorbital nerve preserved. The periosteum and the orbital septum were incised along the whole length of the infraorbital rim. The fat that was exposed through the incision was either removed or preserved and fixed to the outer soft tissue with sutures. Cosmetic results were good and the oral incision healed without infection. Six patients developed numbness in the infraorbital region, five of whom recovered within 3 months; the other recovered by 6 months postoperatively.
睑成形术是当今最常见的美容手术之一。突出的脂肪和睑颊交界处是最明显的衰老迹象，需要引起注意。在经口内途径进行颧骨缩小术时，我们偶尔发现眶脂肪可通过眶下缘的穿孔骨膜暴露。因此，我们开发了一种新的经口途径睑成形术。对17例年龄在26至38岁之间的患者进行了研究，其中6例曾有过不成功的睑成形术，1例有下睑受伤史。手术在眶下神经阻滞和局部麻醉下，通过上颌前庭沟的口内切口进行。骨膜在颧骨表面向上掀起至眶下缘，保留眶下神经。沿眶下缘全长切开骨膜和眶隔。通过切口暴露的脂肪要么被切除，要么被保留并用缝线固定在外层软组织上。美容效果良好，口内切口愈合无感染。6例患者出现眶下区域麻木，其中5例在3个月内恢复；另1例在术后6个月恢复。
