Balloon Sinuplasty is a new technique which has revolutionized sinus surgery in recent times.

Hearing aids are the principal means of auditory rehabilitation for patients with moderate to severe sensorineural hearing loss. Although technical improvements and modifi cations have improved the fi delity of conventional aids, hearing aids still have many limitations. Implantable hearing aids offer patients with hearing loss several potential advantages over conventional hearing aids. This presentation will highlight our fi rst experience, the indications, the procedure, the advantages and the current status of totally implantable hearing aids. . The piezoelectric implantable hearing aid functions by connecting the ossicles to an amplifi er using a piezoelectric crystal vibrator. Piezoelectric materials are bioelectric materials with coupled electrical and mechanical properties. Applying a voltage across an appropriately designed piezoelectric rod cause it to bend or lengthen, with a predictable change in defl ection based on the voltage applied. As this rod vibrates in response to the converted auditory signals, it lies in direct contact with the ossicles, thus the sound waves are transferred directly to the ossicles, which then travel along the normal auditory pathway [3]. This is the basic principle involved in the functioning of totally implantable hearing aid (TIHA).
