RESUMO

Objectives: To characterize the audiological profile of the individuals with congenital malformations of the external and/or middle ear, in the Divisão de Saúde Auditiva (DSA) of the Hospital de Reabilitação de Anomalias Craniofaciais (HRAC) of Universidade de São Paulo (USP), in Bauru and to evaluate the benefits and satisfaction of patients fitted with bone conduction hearing aid (BCHA). Model: Analysis of files, evaluation of benefits by means of test of recognition of sentences with competitive noise and by the measures of the functional gain, and evaluation of satisfaction by International Outcome Inventory for Hearing Aids (IOI/HA). Participants: 170 patients? files were analyzed, from which 13 were selected with bilateral congenital malformations of the external and/or middle ear, moderate or severe conductive or mixed hearing loss, and patients fitted with BCHA. Results: The audiological profile (n=170) was characterized by the prevalence of bilateral malformations (53%), of malformations in males (61%), of the moderate or severe conductive hearing loss (80%) and of the fitting of BCHA (56%). The right ear was more affected (32%) when considered the unilateral malformations only. In the selected sample (n=13), the benefit was demonstrated by the best performance obtained in the proposed evaluation, in the condition with hearing aid, when compared to the condition without hearing aid. The satisfaction was confirmed by the high scores obtained in the IOI - HA. Conclusions: Fitting BCHA denoted improvement at speech perception in noise and sound detection. Individuals with congenital malformations of the ear were satisfied with this device, so that must be considered as an option to the treatment of this population.
