We herein report a case of true hypersalivation. A 24-year-old female had been aware of her hypersalivation since the age of 15. Due to the fact that the treatment she has so far received under a diagnosis of psychogenic hypersalivation had not been effective, she was referred to our hospital. The patient's volume of saliva at rest was very high (9-10ml/ 5 min.) and RI examination showed low accumulation at the bilateral submandibular glands. We considered that this phenomenon had occurred because the speed of salivation had overwhelmed the RI accumulation. Sialography revealed an enlargement of Wharton's duct. We thought that was due to the continuous flow of saliva. Submandibular nerve block remarkably decreased the volume of saliva. We therefore concluded that a functional disorder of the submandibular glands had caused the hypersalivation in this case. We prescribed antihistamines, minor tranquilizers, H1 receptor blocker and carbamazepine separately at different times, and carbamazepine proved to be quite effective. We finally resected the left submandibular gland and the postoperative course was consequently more favorable than we had expected. The volume of saliva at rest decreased to 1.5ml/5 min. On the 49th postoperative day and she is now making satisfactory progress.
