The aim of this study was to analyse the results of treatment following reconstruction of intraoral soft tissue using a nasolabial flap, with particular consideration of functional aspects.
In 26 patients (over a period of 10 years), the intraoral repair of the defect was carried out in the anterior floor of the mouth, 19 have received a unilateral and seven a bilateral nasolabial flap. The defects were caused by resection of squamous cell carcinomas (T1-T2) of the intraoral mucosa in 24 cases and osteoradionecrosis with soft tissue loss in two cases.
Complications of local wound healing were observed in three cases. In 23 patients the subsequent prosthetic rehabilitation was successful and allowed a return of masticatory function. In the other three cases, a secondary operation for flap remodelling would have been preferred, but the patients declined these operations.
The nasolabial flap for replacement of soft tissue in the floor of the mouth represents a functional and aesthetically satisfactory alternative to reconstruction by microsurgically anastomosed flaps in cases with defects of up to 5 x 5 cm in size, especially in older, medically compromised patients who are therefore of poorer surgical risk.
本研究旨在分析使用鼻唇瓣修复口腔内软组织后的治疗结果，尤其关注功能方面。
在26例患者中（历时10年），口腔底部前部缺损的修复采用鼻唇瓣，其中19例接受单侧鼻唇瓣，7例接受双侧鼻唇瓣。缺损原因包括24例口腔黏膜鳞状细胞癌（T1-T2）切除，2例放射性骨坏死伴软组织缺损。
3例出现局部伤口愈合并发症。23例患者随后的修复康复成功，恢复了咀嚼功能。另外3例患者，本更倾向于进行瓣重塑二次手术，但患者拒绝了这些手术。
对于口腔底部软组织缺损大小达5×5cm的病例，尤其是年龄较大、存在医学问题且手术风险较高的患者，鼻唇瓣替代口腔底部软组织是一种功能和美学上令人满意的替代显微外科吻合瓣重建的方法。
