Subtotal petrosectomy (STP) is an effective treatment modality for recurrent suppurative otitismedia (CSOM) and cochlear implant (CI) may be combined for auditory rehabilitation. An activetranscutaneous bone conduction implantation system, known as BonebridgeTM (BB) (MED-EL),is indicated for conductive or mixed hearing loss as well as for single-side deafness, but no casesof BB implantation during STP have been reported. A 37-year-old woman who had previouslyundergone radical mastoidectomy visited our clinic. The left side was deaf and the CT scanshowed total ossification of the cochlea, indicating that CI was not possible. STP was performedand bone conduction-floating mass transducer was placed at a sinodural angle. A month later,the sound processor was applied successfully without any complications. This case suggeststhat BB implantation during STP may be another effective therapeutic option for CSOM patientswho have difficulty undergoing CI procedure.
