Hearing Loss in Children with 22q11.2 Deletion Syndrome

Jill Arganbright et al. Laryngoscope. 2025 Feb.

Abstract

Objectives: Hearing loss is considered common in children with 22q11.2 deletion syndrome (22q11.2DS), with a few prior studies reporting a 32%-78% prevalence; mild-moderate conductive hearing loss has been reported most commonly. Overall, however, there remains a paucity of data regarding the frequency, type, age, and progression of hearing loss in children with 22q11.2DS.

Methods: Retrospective chart review was completed, and data combined for two large 22q centers. Inclusion criteria were children with 22q11.2DS and a documented audiogram. Data extracted included a laboratory-confirmed chromosome 22q11.2 deletion; co-morbidities; results of all audiograms and radiologic temporal bone imaging; and otologic surgical procedures.

Results: One thousand seven hundred sixty-nine charts were reviewed; 775 met inclusion criteria. Of these, 563 (73%) children had at least one abnormal audiogram demonstrating hearing loss. A total of 2,536 audiograms were reviewed; 74% of these showed abnormal hearing in at least one ear. Most of the hearing loss was conductive (right ear 76%; left ear 69%) and mild severity. For the children with SNHL, 90% of all follow-up audiograms were stable without progression. Hearing loss was identified across all pediatric age ranges. Ear tube placement occurred in 39% of children.

Conclusion: This study confirms the high incidence of hearing loss for children with 22q11.2DS at some point in their childhood. In our cohort, hearing loss occurred in 73% of children and was most often conductive and mild in severity. The results highlight the importance of otolaryngology and audiology involvement in managing children with 22q11.2DS for timely diagnosis and treatment of hearing loss.
