A 46-year-old man experienced severe lancinating pain in the throat that radiated to the left ear.The pain, which was exacerbated by swallowing or coughing, had lasted for 2 years. The findings of the patients neurological examination were normal. Computed tomographic and magnetic resonance imaging scans of the brain and nasopharynx did not show any abnormality. A diagnosis of idiopathic vagoglossopharyngeal neuralgia was made. In surgery, both the glossopharyngeal and the rami communicans between the vagal and grssopharyngeal nerves were sectioned. The patient was free of pain following the surgery, but complained of hoarseness in voice.Examination showed paralyzed left vocal cord at a paramedian position. In the 12 months following the surgery, the hoarseness has gradually improved and eventually disappeared.
