Diversion of salivary flow to treat drooling in patients with cerebral palsy.

The authors performed six sialodochoplasties between 1991 and 1994 to treat drooling in six children who suffered from cerebral palsy. There were three boys and three girls, aged 13 to 22 years (mean, 16 years). All patients underwent parotid duct rerouting. The first four patients (group I) also underwent associated excision of submandibular ducts, and the last two patients (group II) benefited from rerouting of the submandibular ducts. In group I, results were considered good in two cases, fair in one case, and poor in one case. A fistula of the new Stenon duct appeared in one patient, which required excision and ligation followed by progressive involution of the parotid gland. Both group II patients had excellent and rapid results. The requirements leading to surgical decision are determined. The importance of physiotherapy is emphasized. Surgical techniques are described and discussed, as are objective criteria for the assessment of surgical results, namely salivary radioisotopic scanning.
