Abstract
A complete healing was effected on a 19-year-old male patient of trigeminal neuralgia who was suffering from chronic tonsillitis and complained of pain in the temporal, preauricular and cheek regions, by tonsillectomy on the right side. It was concluded that the pain was caused by the adhesion between n. linguaris, the third branch of the trigeminal nerve that took an anatomically abnormal run and the palatine tonsil on the same side. The authors agree with Dr. Ishikawa in laying stress on the necessity of close examination of the tonsil in the case of trigeminal neuralgia of unknown cause. During the operation of the right-side tonsillectomy, an extraordinary sweating was observed on the left half of the patient's face, and it seems to be explained by Dr. Takagi's sweating reaction theory.
