We pretend to expose a clinical case, of a 19 year old male patient, with CHARGE syndrome diagnosis. Venous malformations of the temporal bone are quite rare, but they are common in this syndrome. Because of a progressive sensorineural hearing loss in his right ear and a cophotic left ear (VIII agenesis), he became a cochlear implant candidate by the age of 16. He had an absolute contraindication to perform surgery in the left ear, so the implant was placed in the right ear, by a suprameatal approach (because of his venous malformation). No complications were registered. Functionally, the cochlear implant raised the mean pure -tone threshold to 42dB.
