Radiological Anatomy of Inner Ear Malformation in Hearing Impaired Children and it ’s Correlation with Hearing Loss: A Hospital Based Observational Study

This study was a prospective observational study done at a tertiary care teaching hospital in north India. The included were children of 1 –7 years with first time detected severe to profound SNHL. The evaluation of hearing was done by brainstem evoked response audiometry. Those with history of chronic suppurative otitis media and conductive hearing loss were excluded. The all included were undergone high resolution computed tomogra phy of the tympano-mastoid region. A written informed consent was taken. The institutional ethics committee approved the study protocol. We screened 130 children of 1–7 years of age with complaints of severe to profound hearing impairment (SNHL) by BERA. We excluded 38 and 14 children who had con ductive hearing loss with or without CSOM and did not give consent, respectively. Among recruited 78 children, 47 (60.3%) had severe (71–90 dB) and 31 (39.7%) had profound (>  90 dB) SNHL. The majority of children (60/78, 76.9%) had a bilateral hearing impairment, only 18 (23.1%) had unilateral hearing impairment. The mean ± SD of age was 3.9 ± 1.3 years (95% CI = 3.6–4.2). The incidence of severe to profound SNHL was higher, though not statistically signifi cant among the girls. Only 7.7% children with severe to profound SNHL were detected within first 2 years of life. Most of the children (92.3%) with severe to profound SNHL were detected after 2 years of age. Among 78 with severe to profound SNHL, 16 (20.5%) children had stru...
