目的:探讨经口径路手术切除咽旁间隙巨大良性肿瘤的可行性。方法:采用经口径路切除6例患者咽旁间隙巨大良性肿瘤,其中气管切开3例。结果:6例肿瘤均顺利完整摘除,术后恢复良好,无并发症。其中神经纤维瘤2例,神经鞘膜瘤2例,多形性腺瘤2例。随访20个月～5年,无复发。结论:术前影像学检查对咽旁间隙良性肿瘤的诊断和治疗有重要价值,尤其可以了解肿瘤范围及其与颈内动静脉的毗邻关系。在此基础上选择合适患者行咽旁间隙巨大良性肿瘤切除术是可行的。
Objective: To investigate the feasibility of trans-pharyngeal resection of giant benign tumor of parapharyngeal space. Methods: 6 cases of parapharyngeal gigantic benign tumors were resected by transoral approach, including 3 tracheotomy. Results: All the 6 tumors were successfully and completely removed, and recovered well without complications. Including 2 cases of neurofibroma, nerve sheath tumor in 2 cases, pleomorphic adenoma in 2 cases. Follow-up of 20 months to 5 years, no recurrence. Conclusion: Preoperative imaging examination of the parapharyngeal space benign tumor diagnosis and treatment of great value, in particular, can understand the extent of the tumor and its adjacent relationship with the internal carotid artery and vein. On this basis, select the appropriate patients parapharyngeal space gigantic benign tumor resection is feasible.
