title: Post-radiotherapy bilateral external auditory canal cholesteatoma.
abstract: In this article, we report a 55-year-old female case was treated with radiotherapy due to nasopharynx carcinoma and diagnosed with bilateral external auditory canal cholesteatoma four years after radiotherapy. Persistent otorrhea was present in the patient and the diagnosis was established through noticing a soft tissue mass eroding external auditory canal anterior wall in temporal bone tomography as well as the otoscopic findings. Canaloplasty and cholesteatoma excision were administered as the surgical treatment.
