Tumors of the rostral maxilla that involve both the oral mucosa and the dermis or subdermis of the dorsolateral muzzle provide unique challenges for the oromaxillofacial surgeon. Traditionally described approaches to such lesions may involve an intraoral incision that extends and involves the upper lip to envelope the involved dermis of the dorsolateral muzzle. However, such an approach unnecessarily resects upper lip tissue resulting in a large defect that likely requires advanced skin flaps or grafts for reconstruction. Such flaps are technically challenging and introduce potential for significance postoperative complications. In this article, we provide a detailed description a combined intra- and extraoral approach that allows for composite resection of tumors of the rostral maxilla that also involve the dorsolateral muzzle. The described technique allows for excellent intraoperative visualization and provides a superior cosmetic outcome that minimizes postoperative complications. In addition, we describe our experience utilizing the technique in three clinical cases.
累及口腔黏膜以及口鼻背外侧真皮或皮下组织的上颌骨前部肿瘤，给口腔颌面外科医生带来了独特的挑战。传统上针对此类病变的手术方法可能包括经口内切口，该切口延伸至上唇，以覆盖口鼻背外侧受累的真皮组织。然而，这种方法会不必要地切除上唇组织，导致较大的缺损，这可能需要采用先进的皮瓣或植皮进行重建。此类皮瓣技术要求高，且会带来显著的术后并发症风险。在本文中，我们详细描述了一种联合口内和口外的手术方法，该方法可对累及口鼻背外侧的上颌骨前部肿瘤进行复合切除。所描述的技术可在术中提供良好的视野，并能实现卓越的美容效果，同时将术后并发症降至最低。此外，我们还介绍了在三个临床病例中应用该技术的经验。
