Sensorineural hearing loss (SNHL) is the most common congenital sensory impairment, 20% to 70% of children with hearing loss suffering from vestibular dysfunction. Comprehensively evaluate the effect of vestibular dysfunction in deaf children.

Methods: Thirty-eight deaf Participant ranged in age from 10-14 years old were evaluated by Bruininks-Oseretsky test of motor proficiency, HUMAC Balance System, Balance Error scoring scale (BESS), Video Nystegmography (VNG), pure tone and speech audiometry. Results: Bruininks-Oseretsky test of motor proficiency (balance subtest) showed lowest median of 1, HUMAC Balance System Back/left showed the lowest mean 47.03±29.16%, BESS on foam surface single leg support showed highest median 4.2±1 and VNG was abnormal in 41% of cases. Conclusions: Deaf children have significant affection of vestibular functions especially balance is severely impaired with eye closed on solid and foam surface so, care giver and physical therapy rehabilitation must perform balance assessment before dealing with SNHL children.
