To report the surgical technique and functional outcomes of the medial canthoplasty for the treatment of exposure keratopathy.
PATIENTS/METHODS: An IRB approved, retrospective review of patients who underwent medial canthoplasty for exposure keratopathy was performed. Patient demographics, reported symptoms, and clinical examination findings were collected and analyzed from pre-operative and follow-up visits.
The study included 73 consecutive cases in which the medial canthoplasty was performed in patients with exposure keratopathy. The average follow-up period was 7.9 months (median: 4.7 months; range: 1-150 months). Complete or partial improvement in ocular symptoms (dryness; pain/irritation; tearing) was achieved in 95% (69/73). Clinically, 85% (41/48) of patients demonstrated a post-operative reduction in lagophthalmos and 90% (60/67) showed improvement in ocular surface findings. Complications were rare (1/73) and reversal of medial canthoplasty was not required in any case.
The medial canthoplasty appears to be a safe and effective technique to narrow the palpebral fissure, provide lower eyelid support, and improve keratopathy. It is an uncomplicated procedure that may be considered for the treatment of exposure keratopathy caused by facial paralysis and lower eyelid malposition.
报告内侧眦成形术治疗暴露性角膜炎的手术技术和功能结果。
患者/方法：对因暴露性角膜炎而行内侧眦成形术的患者进行了一项 IRB 批准的回顾性研究。收集并分析了患者术前和随访时的人口统计学资料、报告的症状和临床检查结果。
本研究包括 73 例连续病例，这些患者因暴露性角膜炎而行内侧眦成形术。平均随访时间为 7.9 个月（中位数：4.7 个月；范围：1-150 个月）。95%（69/73）的患者眼部症状（干燥、疼痛/刺激、流泪）完全或部分改善。临床方面，85%（41/48）的患者术后睑裂闭合不全减轻，90%（60/67）的患者眼表情况改善。并发症罕见（1/73），无 1 例需要逆转内侧眦成形术。
内侧眦成形术似乎是一种安全有效的技术，可缩小睑裂、提供下眼睑支撑，并改善角膜病变。该手术操作简单，对于因面神经麻痹和下眼睑位置异常引起的暴露性角膜炎，可考虑采用该术式。
