[Traumatic perilymphatic fistula. Report of a pediatric case]

Traumatic perilymphatic fistula is an unusual pathology. Generally caused by pencils, swabs, hair buckles, and matches. Among the most frequent symptoms, patients can present hearing loss and vertigo. Diagnosis requires a complete physical examination that includes otomicroscopy, audiometry and computed tomography of both boulders. Treatment depends on the patient's symptoms. In general, it is conservative at first, but may require surgery. We present a clinical case of a 6-year-old boy with perilymphatic fistula secondary to left ear trauma due to swab, which required surgical treatment.
