Background It is well known that early diagnosis and intervention for hearing impairment is crucial for normal development of language and speech and for a normal life in the future. This study was carried out on 58 patients suffering from sensory-neural hearing loss. They were divided into four groups: Group A (n = 16) Group B (n = 22) Group C (n = 14) Group D (n = 6). The first three groups had severe sensory-neural hearing loss and were bilaterally amplified with hearing aids at the time of diagnosis. They were classified according to the age of amplification into group A, which included children amplified before 6 months of age, group B, which included children amplified between 6 and 12 months of age, and group C, comprising children amplified at 12-24 months of age. The last group (group D) included six children with severe to profound sensory-neural hearing loss. This group had undergone unilateral cochlear implantation. Children of this group were implanted at the age of 4 ± 1.2 years. For all children language and speech assessment was performed at school age. The results were compared among all groups. Conclusion Hearing intervention at the age of 6 months had the best outcome in terms of language development, even when compared with the group with late cochlear implantation.
