Conventional behind-the-ear hearing aids after subtotal petrosectomy with blind sac closure

very effective in improving hearing capabilities, but their cosmetic appearance and discomfort due to pressure on the skull are not always acceptable to patients. Boneanchored hearing aids (BAHA) were not yet available in Australia at the time of seeing these patients. Three patients with monaural hearing difficulties had declined a bone conduction hearing aid because of the poor cosmetic appearance and a conventional behind the ear hearing aid was tried. This consideration was based on previous experiences with “transcranial CROS” (fitting of a power hearing aid in the “dead ear”) in patients with unilateral profound sensorineural hearing loss. 3 This was found to improve patient’s auditory capabilities through sound transmission from the non-hearing ear across the skull to the contralateral intact inner ear.
