Tapia's syndrome caused by a neurofibroma of the hypoglossal and vagus nerves: case report.

Tapia's syndrome is characterized by unilateral paralysis of the tongue and vocal cord, and is caused by a lesion of the 10th and 12th cranial nerves below the nodose ganglion, without involvement of the pharyngeal branches of the 10th nerve. The authors report the case of a 25-year-old man who presented with a 4-year history of progressive glossolaryngeal paralysis. Operation through the right laterocervical region allowed complete removal of a neurofibroma involving the 10th and 12th nerves at their crossing below the nodose ganglion.
