An anti-drooling operation in cerebral palsy

Persistent drooling in cases of cerebral palsy can be successfully controlled by a combination of bilateral parotid duct translocation and bilateral submandibular gland excision. Ten children are described who underwent this operation with satisfactory results. Apart from mile transient postoperative swelling of the cheek, there have been no postoperative complications. The importance of bilateral submandibular gland excision is stressed and the operative details are described. These include elevating a flap of buccal mucosa distally from the orifice of the parotid duct and then burying this strip beneath the buccal mucosa posteriorly to emerge in the pharynx just above the tonsillar fossa. The edges are then sutured to the mucosa of the pharynx. In time the parotid secretions pass into the pharynx via the newly created tube of mucous membrane. The technique is simple and the end result is satisfactory.
