Neoplasms, small or large, adjacent to the punctum can create a dilemma as to their removal and its repair. Punctal stenosis, total closure, and punctal ectropion are complications that can occur after surgery. Punctal complications can cause epiphora with secondary chronic blepharoconjunctivitis and skin excoriation due to chronic rubbing or wiping off of tears by the patient. This report will discuss carbon dioxide laser excision of neoplasms adjacent to the punctum. This laser approach provides a bloodless field, minimal postoperative pain, and good postoperative appearance without scar formation. Smaller adjacent lesions cause no punctal abnormality. Larger lesions adjacent to the punctum which have already caused ectropion did not worsen the ectropion postoperatively.
无论是小肿瘤还是大肿瘤，位于泪小点附近都会给其切除及修复带来难题。泪小点狭窄、完全闭合以及泪小点外翻是手术后可能出现的并发症。泪小点并发症可导致溢泪，并继发慢性睑缘结膜炎，以及因患者长期擦拭眼泪而造成皮肤擦伤。本报告将探讨二氧化碳激光切除泪小点附近肿瘤的方法。这种激光治疗方法术野无血、术后疼痛轻微，且术后外观良好，不会形成瘢痕。较小的相邻病变不会导致泪小点异常。已经导致外翻的较大泪小点附近病变在术后并未使外翻情况恶化。
