| Abstract | Introduction: There are few studies that describe the results of auditory pathway assessment in patients with a history of intraventricular haemorrhage (IVH) during the early years of life. Hypoacusis can occur from the earliest stages of IVH. Brainstem auditory evoked potentials (BAEPs) are a useful tool for diagnosing auditory pathway disorders in early childhood. The aim of the present study was to describe the BAEPs findings in patients under 2 years of age with a history of IVH. Patients and methods: We conducted a retrospective observational study in patients under 2 years of age with a history of IVH referred to our hospital for BAEPs over a period of three years. Patients with genetic syndromes associated with hypoacusis were excluded. BAEPs were used to evaluate the presence or absence of any bioelectrical response and latencies of waves I, III and V, as well as of the intervals I-III, III-V and I-V, and also their morphology, amplitude, synchrony and reproducibility. A descriptive analysis was carried out with the calculation of frequencies and percentages. Results: A total of 122 patients were included. Fifty-one per cent of them had a history of Grade I IVH; 42%, Grade II; and 7%, Grades III or IV. A bioelectrical response was obtained in 243 auditory pathways (99.6%). The morphology was found to be altered in 6.2% of the auditory pathways, while amplitudes were decreased in 2.5% of those tested. Latencies for waves I and III were found to be prolonged in 2% and for wave V in 3.6% of patients. The hearing threshold was normal in 64.8%, and 35.2% of cases presented hypoacusis. Conclusions: The prevalence of hypoacusis was high in the sample analysed. Systematic follow-up using BAEPs is recommended in order to detect and treat problems in the auditory pathway in patients with IVH in a timely manner. |
