目的:探讨颏下动脉带蒂皮瓣在下咽恶性肿瘤切除术后修复中的应用。方法:梨状窝鳞状细胞癌患者5例,均为男性,年龄49~70岁,平均年龄61.2岁。其中4例行选择性颈淋巴结清扫术、完整切除肿瘤并保留部分喉功能,将设计好的颏下动脉带蒂皮瓣向下拉至下咽缺损部位进行修复。另1例为梨状窝癌手术后吻合口狭窄的患者,裂开狭窄部位后,利用颏下动脉带蒂皮瓣进行修复。皮瓣大小从7 cm×3 cm~8 cm×5 cm。结果:5例患者手术均获成功,颏下皮瓣成活,供区切口Ⅰ期愈合,术后7~36 d顺利拔除气管套管及胃管。随访10~28个月,患者咽部皮瓣生长良好,言语及吞咽功能满意,颈部瘢痕隐蔽。结论:颏下动脉带蒂皮瓣血供好,易取材,成活率高,是修复下咽恶性肿瘤切除术后缺损的有用材料。
Objective: To investigate the application of submental artery pedicle flap in the repair of pharyngeal malignant tumor. Methods: Five cases of squamous cell carcinoma of the pear-shaped pit were all male, aged from 49 to 70 years, with an average age of 61.2 years. Among them, 4 patients underwent selective cervical lymph node dissection, complete resection of the tumor and retention of some laryngeal function, the designed submental artery pedicle flap was pulled down to the hypopharyngeal defect site for repair. The other one case of pear-shaped nest cancer patients with anastomotic stenosis, split the stenosis site, the use of submental artery pedicled flap for repair. Flap size from 7 cm × 3 cm to 8 cm × 5 cm. Results: All the 5 cases were operated successfully, and the submental flaps survived. The wounds were healed by first intention. Tracheal tube and gastric tube were successfully removed at 7 ~ 36 days after operation. Follow-up 10 to 28 months, the patient’s pharyngeal flap growth well, speech and swallowing satisfactory, hidden neck scars. CONCLUSION: The submental artery pedicle flap provides good blood supply and is easy to take and has high survival rate. It is a useful material to repair the defect after resection of hypopharyngeal malignant tumor.
