Abstract

Background

Extracranial schwannomas, particularly those arising from the masticator space, are rare entities. Given the challenges in pre-operative diagnosis and the potential for misdiagnosis, accurate localization and differential diagnosis are crucial for optimal surgical planning.

Case Report

A 42-year-old woman underwent a head and neck MRI for unrelated reasons and was incidentally found to have a mass in the left masticator space. Radiological findings were suggestive of a schwannoma. An endoscopic-assisted transoral approach was adopted for the resection of the lesion. Histopathological examination confirmed the diagnosis of schwannoma. The patient had an uneventful postoperative recovery.

Conclusion

This case report highlights the feasibility of an endoscopic-assisted transoral approach for the resection of rare masticator space schwannomas. This minimally invasive technique offers potential benefits in terms of reduced morbidity and improved cosmetic outcomes.

经鼻内镜辅助经口入路（EATA）切除咀嚼间隙颅外神经鞘瘤一例。

背景：颅外分裂瘤，尤其是咀嚼肌间隙产生的分裂瘤非常罕见。鉴于术前诊断的挑战性和误诊的可能性，准确定位和鉴别诊断对最佳手术计划至关重要：一名 42 岁的女性因无关原因接受了头颈部核磁共振检查，意外发现左侧咀嚼肌间隙有肿块。放射学检查结果提示为分裂瘤。医生采用内窥镜辅助经口方法切除了病灶。组织病理学检查确诊为分裂瘤。患者术后恢复顺利：本病例报告强调了经口内窥镜辅助方法切除罕见咀嚼肌间隙分裂瘤的可行性。这项微创技术具有降低发病率和改善美容效果的潜在优势。
