Abstract
Hearing loss is one of the most common clinical findings in subjects with malformations of the ear. Treatment consists of surgery and/or adapt a hearing aid amplification by bone (HA VO). Early intervention is critical to auditory stimulation and development of speech and language. ObjectiveTo characterize the audiological profile of subjects with congenital malformation of the external ear and/or middle and evaluate the benefit and satisfaction of using HA VO. MethodA descriptive study, subjects with bilateral congenital malformations of the external ear and/ or middle, conductive or mixed hearing loss, moderate or severe and HA VO users. Evaluation of the benefit test using sentence recognition in noise and measures of functional gain and satisfaction assessment questionnaire using international IQ - HA. Results13 subjects were evaluated, 61% were male and 80% with moderate conductive hearing loss or severe. There was better performance in the evaluation proposal, provided with HA when compared to the condition without HA. ConclusionHA VO showed advantages for the population studied and should be considered as an option for intervention. Satisfaction was confirmed by elevated scores obtained in IQ - HA.
Highlights
Ear malformations occur during embryo development and may affect the outer, middle and inner ear
This study aims to characterize the audiological profile of individuals with congenital malformations of the ear and/or middle ear and assess the benefits and level of satisfaction achieved with bone conduction hearing aids
Thirteen individuals wearing hearing aids for a mean of three years were included in the study
Summary
Ear malformations occur during embryo development and may affect the outer, middle and inner ear. The more common congenital ear anomalies affect the pinna and the ear canal, involving one or both ears. Hearing loss is one of the most common findings in individuals with ear malformations and may occur in varying degrees and types, depending on the level of involvement[1]. Treatment consists of surgery and/or fitting patients with hearing aids. Fitting of hearing aids favors auditory stimulation and the development of speech and language acquisition. Surgery is not indicated in all cases, and is usually performed in subjects aged at least six or seven years[2]
