颏下皮瓣修复头颈肿瘤术后缺损的临床研究

目的 探讨颏下皮瓣在头颈肿瘤切除后组织缺损修复中的应用。方法 对口颊癌、硬腭癌、软腭癌、唇癌、舌癌及下咽癌切除后的组织缺损，用颏下皮瓣进行了一期修复。结果 18例头颈肿瘤病人中，14例皮瓣全部成活，2例腭部修复皮瓣部分裂开坏列，2例腭部修复皮瓣全部坏死。结论 颏下皮瓣在修复头颈肿瘤术后缺损中，具有操作方便，成活率高等特点，但在腭部修复中，易出现裂开坏死。

Clinical study of submental flaps repairing after resecting head and neck neoplasms

Objective To explore the application of submental flaps in repairing tissue defect after head and neck neoplasm resection. Methods Submental flaps have been used to repair defect after resecting head and neck neoplasms, such as tongue neoplasms, buccal mucosa neoplasms, palate neoplasms, lip neoplasms and hypopharynx neoplasms. Results Fourteen submental flaps were alive in 18 patients with head and neck neoplasms. Two submental flaps were partly necrosis in 2 patients with palate neoplasms. Two submental flaps were necrosis in 2 patients with palate neoplasms. Conclusion Submental flaps are easily obtained and kept alive in repairing head and neck defect, but submental flaps are easily necrosis in repairing palate defect.
