目的介绍逆行颊肌黏膜瓣一期修复经鼻内镜切除鼻腔内翻性乳头状瘤术后创面的方法。方法应用鼻内镜经鼻孔完整切除鼻腔内翻性乳头状瘤,采用患侧面动脉前颊支为蒂的逆行颊肌黏膜瓣,经口鼻隧道转移到鼻腔,一期修复肿瘤切除术后创面。结果共治疗3例,术后颊肌黏膜瓣全部完全成活,无并发症发生。结论逆行颊肌黏膜瓣用于修复侵及鼻阈的鼻腔内翻性乳头状瘤切除术后创面,解决了继发鼻腔瘢痕挛缩狭窄的问题。与鼻内镜下肿瘤切除手术同期完成,提高了手术质量,减少了需二期手术矫正继发畸形的可能性。本手术不仅可以修复各种鼻腔肿物切除术后创面,预防鼻腔瘢痕性狭窄形成,而且可以用于治疗既往已经形成的鼻腔瘢痕性狭窄。
Objective To introduce a retrograde buccal mucosal flap for repair of nasal endoscopic nasal inverted papilloma after surgery. Methods Nasal endoscopic transnasal resection of nasal inverted papilloma was performed. The retrobulbar buccal mucosal flap pedicled with the anterior cheek of the lateral arteries was transplanted to the nasal cavity through the nose and mouth tunnel, and the wounds were resected after the tumor resection. Results A total of 3 cases were treated. Buccal mucosal flap completely survived without complications. Conclusions The retrograde buccal mucosal flap is used to repair the nasal inverted papilloma after wound invasion, which solves the problem of secondary nasal scar contracture. With endoscopic resection of the tumor completed the same period, improve the quality of surgery and reduce the need for secondary surgery to correct the possibility of secondary deformity. The operation can not only repair a variety of nasal cavity resection wounds to prevent the formation of nasal cicatricial stenosis, and can be used to treat previously formed nasal scar stenosis.
