下颌骨外旋入路切除咽及咽旁间隙肿瘤

目的：探讨咽及咽旁间隙肿瘤切除的最佳入路。方法：采用下颌骨外旋入路切除咽及咽旁间隙肿瘤12例，其中鼻咽部肿瘤2例，口咽，喉咽部肿瘤5例，咽旁间隙肿瘤5例。对其中的3例恶性肿瘤同期行颈淋巴结清扫术，对咽部缺损明显的3例行前臂游离皮瓣修复2例，胸大肌皮瓣修复1例。结果：12例病变均获得彻底的切除。疗效满意，未见明显的功能受损及严重的并发症。结论：下颌骨外旋入路切除咽及咽旁间隙肿瘤，具有视野开阔，操作安全方便，便于修复缺损，后遗畸形轻微等特点。特别适用于咽及咽旁间隙特殊病变如血管瘤的切除。

Resection of Pharyngeal and Parapharyngeal Space Tumors by Mandibular Swing Approach

Objective: To find a better approach for the resection of pharyngeal and parapharyngeal space (PPS) tumors. Methods: 12 cases of pharyngeal and parapharyngeal space tumors were thoroughly resected via mandibular swing approaches. Among the cases, 2 were nasopharyngeal tumors, 5 oropharyngeal and laryngopharyngeal tumors and 5 PPS tumors.3 cases had neck node dissections.3 cases of severe pharyngeal defects were reconstructed. Results: The tumors in the 12 cases were thoroughly resected without obvious functional defects or severe complications. Conclusion: This procedure provides good exposure of pharynx and PPS,facilitating reconstruction.It is safe and leaves minimal morbidity.
