Background : An accessory parotid gland (APG) is a common anatomical structure that occurs in 10%-56% of individuals. Pleomorphic adenomas are the most common benign tumors of the APG, and their ideal treatment is surgical excision, although there is a risk for aesthetic disorders and facial nerve damage due to the site of origin. Moreover, despite being benign, these tumors are known to recur. Therefore, it is necessary to achieve both reliable excision and avoidance of facial nerve damage. Case presentation : We report a case of a 49-year-old Japanese man with a mass in his left cheek. The lesion was diagnosed as a benign salivary gland tumor derived from the APG by computed tomography imaging, magnetic resonance imaging and fine needle aspiration cytology. We resected the tumor using modified high submandibular incision under the endoscopic-assisted field of view. Discussion and Conclusions : The tumor was less invasive and reliably resected using an endoscope. In surgical treatment, the endoscopic-assisted technique is very useful to achieve complete tumor resection and prevent relapse while avoiding serious complications due to surgical procedures. J.

副耳（APG）是一种常见的解剖结构，在 10%-56%的个体中出现。多形性腺瘤是 APG 最常见的良性肿瘤，其理想的治疗方法是手术切除，尽管由于起源部位，存在美容障碍和面神经损伤的风险。此外，尽管这些肿瘤是良性的，但已知它们会复发。因此，有必要实现可靠的切除并避免面神经损伤。病例报告：我们报告了一例 49 岁日本男性左脸颊有肿块。通过计算机断层扫描成像、磁共振成像和细针抽吸细胞学检查，该病变被诊断为源自 APG 的良性唾液腺肿瘤。我们使用改良的下颌下高位切口在内窥镜辅助视野下切除肿瘤。讨论与结论：使用内窥镜肿瘤侵袭性更小，更可靠地切除。在手术治疗中，内窥镜辅助技术非常有用，可以实现完全切除肿瘤，防止复发，同时避免因手术引起的严重并发症。医学研究杂志 68：376-380，2021 年 8 月。
