Abstract:

Objective: To explore the feasibility and efficacy of the clinical application of transoral endoscopy in the posterior parapharyngeal space. Methods: The clinical data of 2 patients underwent transoral endoscopic nerve sheath tumor resection in the posterior parapharyngeal space were retrospectively analyzed, including clinical symptoms, signs, imaging examinations, pathological types, postoperative complications and their management, and the feasibility of the surgical route was analyzed. Results: The tumors were completely resected in both patients. There was no recurrence at 2 years of follow-up. Postoperative complications included: One patient developed Horner's syndrome postoperatively; one patient developed postoperative unilateral vocal fold paralysis. Conclusion: Transoral endoscopic surgery for resection of parapharyngeal space tumors is a good minimally invasive route with less bleeding, which is safe and controlled, without cervicofacial incision. However, the long-term efficacy still needs to be further verified by a large number of surgical cases.

摘要：

目的: 探讨经口内镜的咽旁后间隙临床应用的可行性及疗效。方法: 通过回顾性分析2例接受经口内镜下咽旁后间隙神经鞘瘤切除术患者的临床资料，包括临床症状、体征、影像学检查、病理类型、术后并发症及其处理，分析手术路径的可行性。结果: 2例患者肿瘤被完整切除，随访2年均未复发。1例颈交感干来源的神经鞘瘤术后出现Horner综合征；1例迷走神经来源的神经鞘瘤术后出现单侧声带麻痹。结论: 经口内镜下手术切除咽旁间隙肿瘤的方法出血少、安全可控，并且面颈部无切口，是良好的微创路径，但长期疗效仍需大量手术病例加以进一步验证。
