Brown-Vialetto-Van Laere syndrome (BVVLS) is a rare neurological disorder. We report our finding about four patients clinically and electrophysiologically diagnosed as BVVLS and denoted their clinical features with comparison to previous reports. The first symptom was bilateral hearing loss and the onset of other cranial nerves involvement varied between 0-15 years. Our patients represented some rare features like upper motor neuron signs in one patient and two cases interestingly developed some clinical improvement. This is the first report of BVVLS from Iran. Our patients which represent Caucasian population had generally similar features like previously reported cases.
