Abstract

Introduction: Cancers of the external auditory canal are rare. Surgery may be the treatment of choice for localized cases. Lateral temporal bone resection is one surgical treatment option. It is rarely performed by skilled surgeons and requires caudal and anterior cutting of the tympanic chamber bone, which is not usually performed in ear surgery. It is imperative to ensure that the internal jugular vein and important nerves are present.

Case presentation: In this report, we describe a case of adenoid cystic carcinoma of the external auditory canal in which lateral temporal bone resection was safely performed using intraoperative navigation. A 33-year-old woman was diagnosed with an adenoid cystic carcinoma of the right external auditory canal by another physician and presented to our department. After close examination, she was diagnosed with T3N0M0 cancer of the external auditory canal and was referred to our department for lateral temporal bone resection. Although the patient had a high venous arch, intraoperative navigation enabled unblocked resection without exposing the tumor or damaging the vital tissues.

Conclusion: Intraoperative navigation is considered a safer lateral temporal bone resection approach.

术中导航系统应用于高静脉弓耳道癌1例。
外耳道的癌症是罕见的。手术可能是局部病例的治疗选择。外侧颞骨切除术是一种手术治疗选择。它很少由熟练的外科医生进行,并且需要对鼓室骨进行尾侧和前部切割,这在耳科手术中通常不进行。必须确保颈内静脉和重要神经的存在。病例介绍:在本报告中,我们描述了一例外耳道腺样囊性癌,在术中导航下安全地进行了外侧颞骨切除术。一位33岁的女性被另一位医生诊断为右外耳道腺样囊性癌并来到我科。经仔细检查,诊断为外耳道T3N0M0癌,转至我科行颞骨外侧切除术。虽然患者静脉弓高,术中导航使切除通畅,不暴露肿瘤或损伤重要组织。结论:术中导航被认为是一种更安全的颞外侧骨切除入路。
