Medial canthoplasty surgically fuses the upper and lower lids medial to the puncta. The authors modified the procedure by inserting a temporary lacrimal stent in order to avoid kinking and scar contracture of the canaliculi.
A medial canthoplasty successfully corrected lower eyelid laxity in 14 patients with the following conditions: (1) exposure and/or neurotrophic keratitis with medial ectropion and/or retraction of the lower eyelid (11 patients), and (2) inability to retain a prosthesis because of lower eyelid ectropion and contracture of the inferior conjunctival fornix (3 anophthalmic patients).
All patients had a satisfactory cosmetic result despite minimal vertical and horizontal narrowing of the palpebral fissure. Complications included partial wound dehiscence and pyogenic granuloma.
The modified medial canthoplasty described in this article corrects medial ectropion with minimal cosmetic deformity.
内眦成形术通过手术将泪点内侧的上睑和下睑融合。作者通过插入临时泪道支架对该手术进行了改良，以避免泪小管扭结和瘢痕挛缩。
14例患者接受内眦成形术成功矫正了下睑松弛，这些患者存在以下情况：（1）伴有下睑内侧睑外翻和/或退缩的暴露性和/或神经营养性角膜炎（11例患者），以及（2）因下睑睑外翻和下结膜穹窿挛缩而无法佩戴义眼（3例无眼球患者）。
尽管睑裂在垂直和水平方向上仅有轻微变窄，但所有患者的美容效果均令人满意。并发症包括部分伤口裂开和化脓性肉芽肿。
本文所述的改良内眦成形术可矫正内侧睑外翻，且美容畸形最小。
