Objective: To explore the application of endoscopy and clinical effect of endoscopic resection of benign tumor in infratemporal fossa. Methods: The clinical data of 11 patients with benign tumors in infratemporal fossa admitted to the Department of Otorhinolaryngology Head and Neck Surgery and Skull Base Surgery of the Affiliated Hospital of Qingdao University from January 2016 to September 2018 were retrospectively analyzed. There were 6 males and 5 females, with the age ranging from 11 to 63 years old. The main clinical manifestations were pharyngeal foreign body sensation, submaxillary pain, maxillofacial numbness and tongue numbness. Imaging examination showed that the tumor was round and had a clear boundary with the surrounding tissue. All the patients underwent endoscopic surgery. Appropriate surgical approach was selected according to the location of the tumor and its relationship with the internal carotid artery. The endoscopic surgical approaches included trans-oropharyngeal approach in 7 cases, trans-lateral pterygomandibular raphe approach in 1 case and trans-medial pterygomandibular raphe approach in 3 cases. The pathological results, prognosis, complications and relapse of patients were summarized through descriptive statistics. Results: The tumors were completely resected under endoscope in all patients, and there was no significant complication occurred after surgery. The average pain VAS score was 3.1 after surgery and average hospital stay was 5.9 d. The postoperative pathological diagnoses consisted of 6 cases of pleomorphic adenoma, 4 cases of neurilemmoma and 1 case of basal cell adenoma. All patients were followed up regularly from 6 to 39 months without recurrence of tumor. Conclusion: Endoscopic resection of benign tumors in infratemporal fossa has the advantages of minimal damage, rapid recovery, few complications, and definite curative effect, which can be used as an important alternative for surgical treatment of benign tumors.
目的： 探讨内镜在颞下窝良性肿瘤切除术中的应用及临床疗效。 方法： 回顾性分析青岛大学附属医院耳鼻咽喉头颈外科、鼻颅底外科2016年1月至2018年9月采用内镜手术治疗的11例颞下窝良性肿瘤患者的临床资料,其中男6例，女5例，年龄11~63岁。患者主要临床表现为咽部异物感、颌下疼痛、颌面部麻木和舌麻木等。影像学检查提示肿瘤类圆形，与周围组织边界清楚。所有患者均采用单纯内镜手术，根据肿瘤所在的区域及其与颈内动脉的关系选择适当的手术径路，其中内镜经口-咽侧径路7例、内镜经口-翼下颌皱襞外侧径路1例、内镜经口-翼下颌皱襞内侧径路3例。采用描述性统计学方法分析患者病理结果、手术疗效、并发症及复发情况等。 结果： 所有患者均于内镜下彻底切除肿瘤，术后无明显并发症发生，平均疼痛VAS评分3.1分，平均住院时间5.9 d。术后最终病理结果:多形性腺瘤6例、神经鞘瘤4例、基底细胞腺瘤1例。患者术后随访6~39个月，无肿瘤复发。 结论： 内镜下切除颞下窝良性肿瘤具有损伤小、恢复快、并发症少、疗效确切等优点，可作为该区域良性肿瘤手术治疗的重要供选方法。.
