“…Masuda et al also reported cochlear nerve deficiency as the most frequent finding in 69 children with unilateral hearing loss, as was described by Usami et al in a mixed group of over 500 children and adults . However, cochlear dysplasia was the most common finding in two larger series and EVA was the most common finding in another recent report . We postulate that this too may be related to the severity of hearing loss.…”

“…The most common radiologic finding in the SSD group (and overall) was cochlear nerve deficiency, followed by cochlear dysplasia and EVA. These were also the leading three findings reported in previous publications, however the reported rate of each finding was variable .

Objective To examine the imaging findings on computer tomography (CT) and magnetic resonance imaging (MRI) in pediatric single‐sided deafness (SSD) and asymmetric hearing loss (ASH). Methods The medical records of 189 pediatric patients with SSD and ASH were retrospectively reviewed, and imaging findings were compared. SSD was defined as unilateral profound hearing loss and contralateral normal hearing ear. In the ASH group, ASHw was defined as the worse hearing ear with profound hearing loss, while ASHb was defined as the better hearing ear with mild‐moderate hearing loss. Results There were 170 patients with SSD and 19 patients with ASH. In the SSD group, 83 patients (48.8%) had imaging findings associated with hearing loss. In the ASH group, such imaging findings were found in six (31.6%) of the ASHw and in five (26.3%) of the ASHb ears. The most common finding in the SSD group was cochlear nerve deficiency (50.6%), followed by cochlear dysplasia (39.8%) and enlarged vestibular aqueduct (26.5%). In the ASH groups, cochlear dysplasia was seen in three (50%) of ASHw ears and in two (40%) of the ASHb ears, and enlarged vestibular aqueduct was seen in three (50%) of ASHw ears and in two (40%) of the ASHb ears. Conclusion Imaging studies identified the etiology in half of the cases of SSD and in one‐third of ASH patients. Our findings strongly support the use of imaging studies in the evaluation of pediatric SSD and ASH. Level of Evidence 4 Laryngoscope, 130:1007–1010, 2020

Benefits of Cochlear Implantation in Childhood Unilateral Hearing Loss (CUHL Trial)

2021

View full text Add to dashboard Cite

Objectives/Hypotheses: Children with unilateral sensory hearing loss (UHL) struggle to understand speech in noise and locate the origin of sound and have reduced quality of hearing. This clinical trial will determine the benefits of cochlear implantation in children with UHL.Study Design: Prospective clinical trial. Methods: Twenty children with at least moderate to profound sensory hearing loss and poor speech perception (word score <30%) in one ear and normal hearing in the contralateral ear participated in a Food and Drug Administration-approved clinical trial. Subjects were evaluated for speech perception in quiet, speech perception in noise, sound localization, and subjective benefits after implantation.Results: CNC word score perception in quiet significantly improved (1% to 50%, P < .0001) by 12 months after activation. Speech perception in noise by BKB-SIN significantly improved in all three noise configurations; there was a 3.6 dB advantage in head shadow (P < .0001), a 1.6 dB advantage in summation (P = .003), and a 2.5 dB advantage in squelch (P = .0001). Localization improved by 26 at 9 months (P < .0001). Speech, Spatial, and Qualities (SSQ) demonstrated significant improvements in speech (5.2 to 7.4, P = .0012), qualities of hearing (5.9 to 7.5, P = .0056), and spatial hearing (2.7 to 6.6, P < .0001). SSQ subscales associated with binaural hearing were significantly improved, as was listening effort (P = .0082). Subjects demonstrated a non-significant improvement in fatigue.Conclusions: This study demonstrates that children with UHL significantly benefit from cochlear implantation.
