<prompt> Which Intervention is best in patient operated for bilateral acoustic neuroma for hearing rehabiliation:Brainstem hearing implantBilateral cochlear implantUnilateral cochlear implantHigh power hearing aid  <response>: Ans.: A Brainstem hearing implant Closure of perforation of pars tensa of the tympanic membrane is called myringoplasty- P.L Dhingra 5th416AUDITORY BRAEM IMPLANT ABJ P.L. Dhingra 5th 141This implant is designed to stimulate the cochlear nuclear complex in the brainstem directly by placing the implant in the lateral recess of the fourth ventricle. Such an implant is needed when CN VI If has been severed in surgery of vestibular schwannoma. In these cases, cochlear implants are obviously of no useIn unilateral acoustic neuroma, auditory brainstem implant ABI is not necessary as hearing is possible from the contralateral side but in bilateral acoustic neuroma as neurofibromatosis -2, rehabilitation is required by ABICOCHLEAR IMPLANT PL.

Patient must also have anadequate surviving spiral ganglion cell population on the side of implantation, if it is to be successful.Often of no help on the affected side, since the cochleovestibular nerve is usually functionallycompromised during the surgical removal of the lesion. However, in rare cases when the nerve is leftfunctionally intact but the cochlea is left damaged, the cochlear implant has been used successfully.Auditory Brainstem Implant is currently used only in patients with NF-2 and is always implanted simultaneously with tumorremoval usually during excision of the patients second tumor. It is useful in patients who have hadboth cochleovestibular nerves sacrificed, since this implant stimulates the cochlear nuclear complexin the brainstem directly
