“…It should, however, be noted that time elapsed since the labyrinthectomy does not seem to be a predictor of the obliterative process. Osborn et al (11) reports implantation 21 years after a labyrinthectomy, and this is in keeping with our findings that the cochlea can remain patent many years after the original surgery.…”

“…These include reduced risks associated with another surgical procedure and anesthetic. Also, surgical labyrinthectomy may lead to soft tissue scarring or even ossification in the cochlea which could prohibit later implantation (40), although this is not a uniform response (41,42). Finally, immediate implantation reduces the time of deafness and performance with a CI is correlated with duration of deafness (43).…”

Objective Compare pre and postoperative performance in patients undergoing cochlear implantation (CI) for unilateral severe-to-profound sensorineural hearing loss (single-sided deafness, SSD). Study design IRB-approved, prospective Setting Tertiary center Patients Twenty-nine patients have undergone CI for SSD. SSD was due to Ménière's disease (MD) in 10 subjects; these also suffered from recalcitrant vertigo spells and in these 10 patients along with 2 others the CI was placed simultaneous with a labyrinthectomy. Intervention(s) CI with or without labyrinthectomy. Main outcome measure(s) CNC word and AzBio sentences in quiet were administered to the implanted ear. A multiple-loudspeaker sound localization test was administered in the bilateral listening condition. All data were collected pre-operatively and 3, 6, 12-months post-operatively with post-operative data available for 19 subjects. Additionally, a tinnitus handicap questionnaire is administered pre- and 12-months post-operatively. Results CNC word and AzBio sentence scores showed improvement in the implanted ear. Sound localization appeared to improve in an experience dependent fashion in some patients. Most patients reported diminished tinnitus following cochlear implantation. All patients undergoing labyrinthectomy experienced resolution of vertigo attacks. Conclusions CI restores auditory function to the deafened ear. Additionally, the binaural input appears to improve sound localization for most patients. In patients with severe hearing loss and recalcitrant vertigo attacks due to MD, simultaneous labyrinthectomy and CI effectively relieves vertigo attacks and improves auditory function.

“…Los pacientes también deben conocer que posterior a la cirugía quedarán con sodera completa del oído operado. Sin embargo, la cofosis posoperatoria del oído al que se le realizó la laberintectomía, es un problema que podría ser resuelto con un implante coclear colocado en la misma cirugía 11 o en un segundo tiempo quirúrgico 12 . Más aún, en el futuro, es probable que se pueda recuperar la función vestibular, ya que se están desarrollando implantes vestibulares en seres humanos 13 .…”
