Abstract: Objective: To analyze the effect of the tumor resection in infratemporal fossa by submandibular incision with longitudinal mandibular osteotomy approach. Methods: Between January 2015 and February 2018, 7 patients with tumors in infratemporal fossa were treated by submandibular incision with longitudinal mandibular osteotomy approach. The patients were followed up to evaluate the complications and tumor recurrence. Results: All 7 patients had complete tumor resection with functional preservation of the inferior alveolar nerve. Postoperatively, there were no evidence of tumor recurrence and technique-related morbidities at 6 months to 3 years follow-up. Conclusion: This novel technique is useful for providing excellent access to tumors in infratemporal fossa.

Key words: infratemporal fossa, tumor, mandibulotomy approach

摘要： 目的：探讨下颌下切口结合下颌升支纵形离断入路切除颞下窝肿瘤的疗效。方法：回顾性分析2015-01—2018-02期间，我科收治的7例颞下窝肿瘤患者的临床资料。所有患者均采用下颌下切口结合下颌升支纵形离断入路切除肿瘤，随访术后并发症和肿瘤复发情况。结果：术野显露良好，肿瘤完整切除，无下牙槽神经损伤。随访6~36个月，1例迷走神经副神经节瘤患者出现声音嘶哑和饮水呛咳，余6例未出现相关并发症，无肿瘤复发。结论：下颌下切口结合下颌升支纵形离断入路切除颞下窝肿瘤，具有创伤小、创口暴露充分、术后并发症少等优点，值得临床推广应用。
