He had had no previous operations on the head and neck. He did not smoke and there was no relevant medical history. The pain spread across his right temple and right angle of his mandible. Four months later he complained of a sensation similar to an “elastic band hitting his face” which occurred only during the first bite of every meal. He was treated successfully with oral antibiotics for a postoperative infection in the left body of his mandible. The operation went to plan and there were no complications. It involved 8 mm advancement and 3 mm impaction of the maxilla through a Le Fort I osteotomy and bilateral sagittal split osteotomy to retract and raise the mandible.

This results in denervation and supersensitivity of the sympathetic receptors that control the myoepithelial cells. Although most cases occur as a postoperative complication it has also been reported preoperatively.1 The cause is largely unknown, but it could occur after loss of or damage to the sympathetic innervation to the parotid gland during operation. It gradually improves with each further bite and characteristically lasts a few seconds. It is the development of a severe cramping pain in the parotid region at the same side as the operation and is usually experienced after the first bite of every meal. Introduction First bite syndrome is an uncommon complication of operations that involve the infratemporal fossa and the parapharangeal space or deep lobe of the parotid, or both.
