Abstract
ObjectiveTo investigate the clinical characteristics, diagnosis and treatment of adenoid cystic carcinoma in external auditory canal.
MethodsA retrospective analysis was performed on 6 patients with adenoid cystic carcinoma in external auditory canal treated in Subei People's Hospital of Jiangsu Province from January 2008 to December 2020.The clinical manifestation, treatment and follow-up results were analyzed. Treatments included mastoidectomy(n=2), subtotal temporal bone resection and superficial parotid gland resection and temporal muscle repair(n=3), subtotal temporal bone resection and superficial parotid gland resection and partial deep parotid gland resection and temporal muscle repair(n=1).
Results6 patients were followed up for 2-8 years, 4 patients were followed up for more than 5 years. One case had recurrence and one case had distant metastasis.
ConclusionsAdenoid cystic carcinoma of the external auditory canal is not easy to be diagnosed in a timely manner, the tumor growth is slow, it is easy to recur and prone to lung metastasis. Extended resection of the tumor with surgery plus postoperative adjuvant radiation prolong survival and reduce recurrence. It's an effective treatment for adenoid cystic carcinoma of the external auditory canal.
