Auditory Function Impairment in Down Syndrome

The goal of a new study was to ascertain the occurrence and nature of auditory function disorders in individuals with Down syndrome while also identifying factors influencing the severity of hearing impairment.

This study examined 30 Down syndrome patients aged 3-18 years who visited the ENT clinic at Tishreen University Hospital, Syria, between 2021 and 2022. The study entailed – collecting detailed patient histories; comprehensive ear, nose, and throat examinations; and auditory tests. 

Overall, 53.3% of participants experienced hearing loss; the primary cause was conductive hearing loss (81.25%), followed by sensorineural hearing loss (12.5%) and mixed hearing loss (6.25%). Meanwhile, mild hearing loss was noted among 15.6% of the cases without profound hearing impairment. The most common etiology identified for hearing loss was cerumen impaction (33%), while serous otitis media accounted for approximately 13.3%. Notably, none of the participants were diagnosed with acute suppurative otitis media.

Hearing impairment significantly impacts individuals with Down syndrome. Prompt and accurate diagnosis, effective early treatment, and regular audiological assessments are crucial for managing such issues and preventing disruptions to their quality of life (QoL). This pioneering study highlights the substantial prevalence of hearing loss in individuals with Down syndrome, emphasizing the importance of ongoing monitoring and adherence to international recommendations for effective management.
