Reconstruction of nasal defects can be a difficult task if large amounts of nasal mucosa are missing. We have found the inferior turbinate mucosal flap to be a reliable and effective flap in a series of 16 patients undergoing nasal reconstruction or repair of septal perforations. Most of these patients had insufficient mucosa to use traditional flaps harvested from the nasal floor or the lateral nasal wall. Eight patients underwent reconstruction of septal perforations, 9 patients underwent nasal reconstruction of large nasal defects after tumor extirpation, and 1 patient underwent closure of a palatal fistula. Six of the septal perforations were closed completely and 3 were reduced in size by 50%. All 11 turbinate flaps used for nasal reconstruction (2 patients had bilateral flaps) survived. Two flaps underwent mild superficial epidermolysis without flap necrosis or exposure of overlying cartilage grafts. The turbinate flap is based anteriorly and provides large amounts of well-vascularized mucosa. The turbinate is rotated anteriorly and bivalved and the conchal bone is removed to increase the dimensions of the flap. The flap is sometimes staged to allow transfer of mucosa to distant sites, such as the septum, the nasal ala, and the nasal wall. An anatomical dissection of 10 turbinate flaps on 5 fresh cadaver specimens demonstrated an average flap size of 4.97 cm2. The average length of the flap was 2.83 cm, which is sufficient length to reach the nasal dorsum. A description of the surgical technique and the vascular supply of this flap will be discussed.
如果大量鼻黏膜缺失,鼻缺损的修复可能是一项艰巨的任务。我们发现在一系列16例接受鼻重建或鼻中隔穿孔修复的患者中,下鼻甲黏膜瓣是一种可靠且有效的皮瓣。这些患者中的大多数鼻黏膜不足,无法使用从鼻底或鼻侧壁获取的传统皮瓣。8例患者接受了鼻中隔穿孔修复,9例患者在肿瘤切除后对大的鼻缺损进行了鼻重建,1例患者进行了腭裂瘘修补。6例鼻中隔穿孔完全闭合,3例穿孔面积缩小50%。所有用于鼻重建的11个鼻甲瓣(2例患者使用双侧皮瓣)均存活。2个皮瓣出现轻度浅表表皮松解,未发生皮瓣坏死或覆盖软骨移植物暴露。鼻甲瓣以前方为蒂,可提供大量血运良好的黏膜。将鼻甲向前旋转并二分,去除鼻甲骨质以增加皮瓣面积。有时可分阶段进行皮瓣转移,以便将黏膜转移到远处部位,如鼻中隔、鼻翼和鼻壁。对5个新鲜尸体标本上的10个鼻甲瓣进行解剖显示,皮瓣平均面积为4.97平方厘米。皮瓣平均长度为2.83厘米,足以到达鼻背。本文将讨论该皮瓣的手术技术及血供情况。
