Tympanic neurectomy versus submandibular duct retropositioning in treatment of drooling

Twenty-eight patients with cerebral palsy and complaining of drooling were included in this study. The patients were randomly divided into two equal groups. Group I underwent bilateral retropositioning of the submandibular salivary duct, while group II was operated upon by bilateral tympanic neurectomy and unilateral chorda tympani nerve section. In spite of the few minor complications, the results of group I were more satisfactory in controlling drooling
