Abstract：
Extensive resections of advanced stage oral cavity cancers can sometimes lead to significant through and through buccal defects with compromise of the oral commissure/lips. Post free flap reconstruction, such patients often require a secondary delayed commissuroplasty to assist with improved oral function and quality of life. In current literature, limited methods exist for free flap commissuroplasty with some key limitations, particularly their negative impact on buccal sulcus or oral vestibule. Our technique of the triangular cheek flap commissuroplasty allows the surgeon to reconstruct a neo-commissure without compromising the oral vestibular depth or decreasing mouth opening. Through this pictorial essay we describe a detailed surgical technique for secondary reconstruction of the oral commissure.
摘要：
晚期口腔癌的广泛切除有时会导致明显的贯穿和贯穿口腔缺损，并损害口腔连合/嘴唇。游离皮瓣重建后，这些患者通常需要二次延迟连缝成形术，以帮助改善口腔功能和生活质量。在当前的文学中,游离皮瓣连缝成形术的方法有限，有一些关键的局限性，特别是它们对颊沟或口腔前庭的负面影响。我们的三角形颊瓣联合成形术技术使外科医生能够重建新连合，而不会损害口腔前庭深度或减少张口。通过这篇图片文章，我们描述了一种用于二次重建口腔连合的详细手术技术。
