Transtympanic neurectomies for control of drooling.

Twenty patients of drooling were studied. Of the 20 patients studied, 8 patients underwent bilateral chorda tympani nerve section, and 12 patients underwent bilateral chorda tympani nerve along with bilateral tympanic nerve sections. Bilateral chorda tympani nerve section in combination with bilateral tympanic nerve section is a better and more effective procedure for control of drooling than bilateral tympanic nerve section alone. In both these methods there is immediate stoppage of drooling i.e. on 2nd postoperative day but chances of recurrence of drooling are less in chorda tympani nerve section in combination with tympanic nerve section (17%) than chorda tympani nerve section alone (38%).
