外耳道癌是一种罕见的恶性肿瘤。复杂的解剖结构和肿瘤与周围组织在有限空间内的关系使得在手术期间难以获得安全的切除边缘。高颈静脉球（HJB）是一种具有重要外科意义的解剖变异，使EAC癌的外科手术复杂化。一位73岁的女性，有3个月的右耳疼痛史。病理结果及电脑断层扫描显示EAC癌，这是扩大到中耳（ME）。虽然ME内部没有空腔，但检测到HJB。手术治疗采用颞部切口颞部开颅取得了完整的切除肿瘤和保留面神经功能。患者痊愈，无并发症，术后17天出院。颞部切口开颅是治疗EAC癌合并HJB的有效方法。
External auditory canal (EAC) carcinoma is a rare and unusual malignancy. The complex anatomy and relationship between the tumor and surrounding tissues in a limited space render it difficult to attain safe resection margins during surgery. A high jugular bulb (HJB) is one such anatomical variation that has important surgical implications that complicate the surgical procedure for EAC carcinoma. A 73-year-old woman presented with a 3-month history of right ear pain. Pathological findings and computed tomography (CT) revealed EAC carcinoma, which was expanding to the middle ear (ME). Although there was no cavity inside the ME, an HJB was detected. Surgical treatment using a temporal incision for temporal craniotomy achieved complete resection of the tumor and preserved facial nerve function. The patient recovered without complications and was discharged 17 days after the operation. Temporal incision and temporal craniotomy is a useful approach for EAC carcinoma with HJB.
