ABSTRACTSix hundred patients were studied, the age range was from three months to 12 years of age. All the patients were carefully studied at the pediatric audiologic service of the Instituto de la Comunicación Humana. The main points of the survey referred to who was the first person who suspected the hearing deficit in the patient, the reasons that led to the suspicion and finally the age of detection. Methods: Complete audiological examination included pure tone audiometry, sound field impedance audiometry, brainstem auditory evoked potentials and otoacoustic emissions. Of the 600, 72 patients were selected because they had serious degrees of bilateral hearing loss. Results: The average age of the patients was 4.41 ± 3.11 years old (median ± standard deviation), they were detected to have hearing loss at an average of 1.91 ± 1.16 years old. In 26 (36.1%) patients the reasons for detection was their lack of response to calling; 21 (29.1%) patients did not show answers to sound stimuli at home; 17 (23.6%) did not acquire language; five (6.9%) did not awake with to sound stimuli; two (2.7%) showed regression in language and one (1.3%) did not pay attention to class orders at school. In 59 (81.9%) cases the mother of the patient was the person who suspected the hearing deficit, in four (5.5%) patients it was the father, in three (4.1%) patients it was the physician, in three (4.1%) it was the language therapist, in (2.7%) two cases it was the grandmother and in one (1.3%) case it was the teacher. Conclusion: People with proper education in the field will allow early detection of hearing loss disorders and their adequate management.
