ABSTRACT

Objective. To know the incidence of hearing loss in the Ministry of Health of Tlaxcala and report the results of studies of auditory evoked brainstem (BAEP) of children who were suspects in hearing screening test. Material and methods. This is a descriptive observational study on 171 children who failed the test of hearing screening, Audiology Service referred to in the Women’s Hospital during the period June 2010 to December 2012 was performed by detecting BAEP. Hearing loss is the identification of the V component of greater intensity generated 30 dBnHL considered. The degree of hearing loss was determined by taking into account: the minimum intensity at which the V component is identifiable, the increase in latency of complex IV and morphology in recording electrophysiological components. Results. Hearing loss was detected in 103 children, with an incidence of 2.6 per 1,000 live births. 46.6% and 57.3% were unilateral sensorineural. The average age of detection was 2.6 months. Conclusion. The results of our study are evidence that can be used for advocacy, planning and priority setting in the health system of Tlaxcala.
