Prelingually deaf child is one who is either born deaf or who lost his or her hearing early in childhood, before acquiring language. A child with subnormal hearing acuity suffers from consequences of hearing loss compounded by impaired speech development. The period from birth to 3 years of life is critical for the development of speech and language, therefore, there is need for early identification and assessment of hearing loss and early rehabilitation in children. 40 patients were evaluated clinically, radiologically and audiologically to assess the degree of patient’s handicap. The modes of treatment included use of hearing aid in patients with moderate, moderately-severe, severe or profound HL and cochlear implantation in patients with profound HL. Each patient was followed for 18 months and results were calculated in terms of speech perception (CAP) and language (REELS) development of the patient. Out of the 40 patients, 60% (n = 24) were females and 40% (16) were males. 50% (n = 20) patients had PSNHL, 32.5% (n = 13) had SSNHL, 10% (n = 4) had MSSNHL and 7.5% (n = 3) had MSNHL. 30% (n = 12) of patients had significant radiological findings. Among the hearing aid users patients with PSNHL got no benefit at the end of 18 months whereas the patients with cochlear implantation had significant improvement. Also the patients managed at a younger age (<3 years) had a significantly better outcome then those managed later. Early identification of hearing loss, that is followed by immediate and appropriate intervention results in better language, speech, and social-emotional development when compared to children treated at a later age.
