Abstract

The objective of this work was to evaluate the prevalence of sensorineural hearing loss (SNHL) and distribution of the main risk factors associated to it focusing on their role in the development of deafness and their interaction. We performed a global audiological assessment (through TEOAE, tympanometry and ABR) in 508 infants at risk studying the main risk factors reported by Joint Committee on Infant Hearing (2007). Fifty-one infants (10.03 %) were diagnosed with SNHL (45 bilateral and 6 unilateral) with a mean hearing threshold of 87.39 ± 28.25 dB HL; family history of hearing impairment (HI) and TORCH infections indicated independent significant risk factors (P < 0.00001 and P = 0.024, respectively). High SNHL percentages were evidenced also in NICU babies, due to the various pathologies and risk factors presented by these infants, and among newborns who suffered from hyperbilirubinemia (11.97 and 9.52 %, respectively). The mean degree of hearing loss for children with family history of HI (>100 dB HL) emphasizes the necessity of an early diagnosis to avoid the consequences of auditory deprivation. Craniofacial abnormalities and syndromes associated to HI showed an important relationship (P < 0.00001) with conductive hearing loss. A progressive increase was evidenced in SNHL incidence as the number of risk factors rises (from 5.12 for 2 risk factors to 28.5 % for 5 or more) with a significant difference among the groups (P = 0.049); multiple risk factors showed an additional cofactor for HL (r2 = 0.93). Considering the high SNHL prevalence (10.03 %) in infants at risk, this study highlights the necessity to implement a neonatal hearing screening program in Western Sicily.
