Active middle ear implant after lateral petrosectomy and radiotherapy for ear cancer.

Tumor of the temporal bone is a rare disease with a very poor prognosis. Surgery and postoperative radiotherapy are usually the recommended treatments for squamous cell carcinoma (SCC) of the external and middle ear, which may cause conductive hearing loss. The purpose of this study was to evaluate the audiologic results and compliance of active middle ear implant (AMEI) and establish the feasibility of the procedure in a patient treated for middle ear cancer.
A 73-year-old patient treated with lateral petrosectomy, neck dissection, reconstruction/obliteration by pedicled pectoralis major myocutaneous flap, and postoperative full dose radiotherapy for external and middle ear SCC was selected for AMEI. Preoperative audiometric and speech audiometry tests were performed on both ears before and after the activation.
Pure tone free field audiometry. Binaural free field speech audiogram.
Aided pure tone free field audiometry AMEI results show an increase in air conduction. Speech audiogram showed better discrimination scores in AMEI-aided situations. No complications were observed.
AMEI after surgery followed by radiotherapy for middle ear cancer is feasible. Acoustic results in obliterated ear are satisfactory.
