[Follow-up and evaluation using brain-stem evoked potentials of a pediatric population diagnosed as premature]

We study 65 patients coming from neonatology service with a diagnostic of prematurity and we test of audiometric level with brain stem response audiometry during three years, giving importance to the clinics characteristics that have affected during the story in the hospital. We diagnose hearing loss in a 41% of the patients, and in one case (5.88%) is retrocochlear (17.6%) as with no valuable. After three years only one patient presents persistent hearing loss; while in the first exploration 17 are considered pathologics. The prematurity by itself and without others clinic factors doesn't involve an important risk in the generation of hypoacusy.
