Double Posterior Labyrinthotomy Technique: Results In Three Med-El Patients With Common Cavity

Abstract

These results demonstrate the success of the double posterior labyrinthotomy approach with modified cochlear implant, and this could be recommended as the procedure of choice in children presenting to an implant team with a common cavity.

Cochlear implantation in 21 patients with common cavity malformation

“…However, cerebrospinal fluid (CSF) gusher, anomalous course of the facial nerve, and penetration of the electrode array into the internal auditory canal (IAC) remain major challenges for surgeons. Three surgical approaches for CI are used in CC deformity: the facial recess approach, canal walldown mastoidectomy approach, and transmastoid labyrinthotomy approach [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…Although previous studies have reported that most patients with CC benefit from CI, outcomes varied greatly among individuals, from detection of environmental sounds to excellent performance similar to that of patients with normal cochleas [4][5][6][7][8][9][11][12][13][14][15][16]19]. In addition, few studies have focused on the long-term postoperative audiological and speech development of patients with CC.…”

Cochlear implantation for a child with cochlear nerve deficiency: Parental perspectives explored through narrative

“…In contrast to studies demonstrating speech and language gains from cochlear implantation for children with ANSD (reviewed in Rance, 2005) and common cavity deformity (e.g. Beltrame et al, 2005), outcomes have been less clear in the case of CND. There are a number of studies that have attempted to predict which children with CND will benefi t from cochlear implantation based on pre-operative auditory behaviours with hearing aids and anatomical characteristics determined by magnetic resonance imaging and computed tomography.…”

Real-Time Intraoperative Computed Tomography to Assist Cochlear Implant Placement in the Malformed Inner Ear

“…At this point, it was decided to advance the array using the loop-delivery method of Beltrame et al (8). A second labyrinthotomy was made adjacent to the first.…”

“…Additionally, a heightened risk of complications such as cerebrospinal fluid gusher or imprecise electrode insertion has been reported. Inadvertent placement of the array into the internal auditory canal (IAC) is a complication well known to cochlear implant surgeons (4,5,8).…”
