Objective: To detect the clinical and pathological features of the adenoid cystic carcinoma of external audi-tory canal, and to improve its diagnosis and treatment level. Method: A retrospective analysis has been performed on patients with ACCEAC by their clinical manifestation, the therapy and follow-up results since 8 years ago as well as the combination with there view of related literature. Result: Patients without recurrence of postoperative follow-up of six months. Conclusion: Adenoid cystic carcinoma of external auditory canal, which is rarely seen in clinic, is not easy to exact diagnosis in early stage. It progresses slowly and tends to invade parotid and even intracranial cavity. It also has the tendency of recurrence and pulmonary metastasis. So, it’s necessary to do both aggressive surgery and postoperative irradiation. The long term follow-up indicates that the tumor has a poor prognosis.
