Abstract

Background: External auditory canal (EAC) carcinoma is rare and difficult to diagnosed. Only 5% of the cases that recognized as adenoid cystic carcinoma (ACC). Therefore, the optimal management of ACC of the EAC has not been established. Treatment depends on the tumor stage as with other EAC malignancy. One of the surgical options that can provide optimal results and achieve negative surgical margins is lateral temporal bone resection (LTBR). Purpose: Provide information related to the management of LTBR in ACC. Case report: A 49-year-old male with complaint of otalgia in right ear for more than 7 months, accompanied by otorrhea and hearing loss. Otoscopy of the right ear showed stenosis of the EAC which caused by protrusion of the tumor from the ear canal posterior. Pure tone audiometry examination of the right ear showed moderate severe mixed hearing loss (70 dB). Temporal Bone CT scan revealed soft tissue mass in the right EAC to the tympanic membrane and has not extended to the tympanic cavity, and also eroded the posterior wall of the ear canal, the mastoid antrum was clean. Histopathological results from biopsy and surgery showed adenoid cystic carcinoma. Method: Literature search on PubMed using the PICO format with keywords of adenoid cystic carcinoma, external auditory canal, and lateral temporal bone resection. Result: Four articles relevant for critical review related to clinical questions and inclusion criteria. Conclusion: ACC of the EAC is a malignancy that is difficult to diagnose. A thorough physical examination with CT scan and/or MRI can be modalities in establishing the diagnosis. Complete resection with LTBR is the recommended treatment. Long-term postoperative follow-up is required to monitor of the tumor recurrence. Radiation therapy (RT) is required in addition to surgical therapy.
