Abstract

The main function of the eyelids is to support and protect the globe. The lower eyelid and medial canthus are often the location of malignant tumors that can be locally aggressive and require disfiguring surgeries. Chronic epiphora often appears in cases of inadequate reconstruction in this location and can require secondary procedures. We report four cases of medial canthus repair after tumor removal with loss of the inferior canaliculus. The ipsilateral superior canaliculus was removed before being transposed into the lower eyelid. This simple method allows for complete canalicular reconstruction. It obviates the need for artificial material and its potential associated complications. It has the advantage of a one-step eyelid and canalicular reconstruction and prevents epiphora after tumor resection.

摘要

眼睑的主要功能是支撑和保护眼球。下眼睑和内眦常是恶性肿瘤的好发部位,这些肿瘤可能具有局部侵袭性,需要进行毁容性手术。在此部位重建不足的病例中,慢性泪溢常常出现,可能需要二次手术。我们报告了4例肿瘤切除后内眦修复且下泪小管缺失的病例。同侧上泪小管在转位至下眼睑之前被切除。这种简单的方法可实现泪小管的完全重建。它避免了使用人工材料及其潜在的相关并发症。它具有一步完成眼睑和泪小管重建的优点,并可防止肿瘤切除后出现泪溢。
