Objective: To investigate the effectiveness of modified kite flap in repair of soft tissue defect after divided nevus of lateral canthus excision.
Methods: Between October 2010 and April 2018, 20 children (20 eyes) with divided nevus of lateral canthus were admitted. There were 13 boys and 7 girls, with an average age of 7.9 years (mean, 4-14 years). There were 11 cases of moderate range lesions (maximum diameter, 1.5-2.0 cm) and 9 cases of small range lesions (maximum diameter, <1.5 cm). After excising the divided nevus of lateral canthus, the area of soft tissue defect ranged from 0.72 to 3.23 cm2。The modified kite flap was used to reconstruct the structure and shape of lateral canthus.
Results: There were 16 cases of mixed nevus and 4 cases of intradermal nevus. The flaps survived and the incisions healed by the first intention. The patients were followed up 12-22 months (mean, 13.6 months). There was no malformation, valgus, exposure keratitis, or obvious scar. No malignant transformation occurred or nevus recurred during follow-up. At last follow-up, the effectiveness was rated as excellent in 16 cases, good in 3 cases, and poor in 1 case.
Conclusion: The modified kite flap can repair the soft tissue defect after excising the divided nevus of lateral canthus, and obtain the good appearance and function of lateral canthus.
目的: 探讨采用改良风筝皮瓣修复外眦分裂痣切除后皮肤软组织缺损的疗效。.
方法: 2010 年 10 月—2018 年 4 月，收治 20 例（20 眼）外眦分裂痣患儿。男 13 例，女 7 例；年龄 4～14 岁，平均 7.9 岁。中度范围病变（最大直径 1.5～2.0 cm）11 例、小范围病变（<1.5 cm）9 例。外眦分裂痣切除后，遗留皮肤软组织缺损面积 0.72～3.23 cm2。切取改良风筝皮瓣修复缺损，重建外眦结构与形态。.
结果: 病理检查显示混合痣 16 例、皮内痣 4 例。术后皮瓣均成活，切口 Ⅰ 期愈合。患儿均获随访，随访时间 12～22 个月，平均 13.6 个月。外眦无畸形、外翻，无暴露性角膜炎发生，瘢痕形成不明显，随访期间无恶变和复发。末次随访时，疗效评价为优 16 例、良 3 例、差 1 例。.
结论: 改良风筝皮瓣修复外眦分裂痣切除后皮肤软组织缺损，外眦外观及功能均恢复较好。.
