Evolution of Cochlear implant mapping and vestibular function in a pediatric case of Labyrinthitis

Abstract

Background: Vestibular symptoms such as vertigo and imbalance are known to occur in some cochlear implant patients during the immediate postoperative period; however, acute vertigo in implanted children occurring remotely from the postoperative period has not been previously well-described. Case presentation: A three-year-old girl with a history of bilateral sequential cochlear implantation presented with acute labyrinthitis associated with sudden onset of vertigo, balance impairment, and decline in right cochlear implant function 2 years after her most recent implant surgery. We describe her audiological and vestibular testing results during both the acute phase and following medical management and recovery. Conclusion: Acute labyrinthitis should be considered when sudden onset vertigo and/or imbalance presents in children with cochlear implants outside of the perioperative period. Such symptoms should prompt early assessment of cochlear implant function, so that the device can be reprogrammed accordingly.

Vertigo Associated With Cochlear Implant Surgery: Correlation With Vertigo Diagnostic Result, Electrode Carrier, and Insertion Angle

“…However, a postoperative increase of balance dysfunction is also possible. Thus, labyrinthitis could be a cause of late onset of cochlear implant-related vertigo (74). The study presented here does not provide evidence for the suspicion of labyrinthitis, as no signs of vestibular dysfunction were present in three cases with delayed-onset vertigo.…”

The role of vestibular function tests in nontuberculous mycobacterial otomastoiditis: A case report

“…[ 14 ] Timely diagnosis and appropriate outcome assessment can effectively shorten hospitalization and prevent disease progression. This method is similar to that used for the recovery of acute labyrinthitis, [ 15 ] which evaluates the degree of dizziness to infer the effectiveness of the treatment. Thus, we used vestibular tests, including sPSG, cVEMP, and vHIT, to provide an objective assessment of every component and subsystem of balance, allowing specific profiling of the patient.…”

Modern methods of investigating the vestibular function in children

“…Вочевидь, що ці проблеми є дуже важливими, проте є ризик того, що супутнім захворюванням і патологічним станам не приділяють достатньоуваги [5]. Водночас діти із сенсоневральною втратою слуху демонструють як рухові та постуральні порушення, так і порушення рівноваги [6] вестибулярної дисфункції у дітей із сенсоневральною втратою слуху [12,13], ймовірно, спричинену ураженням внутрішнього вуха, що впливає на функцію рівноваги та моторики цих дітей.…”
