Postoperative swelling and trismus after mandibular third molar removal with the lingual split bone technique

Several factors have been suggested as possible causes for the development of the swelling and trismus which occur after the surgical removal of impacted third molar teeth. In this investigation, measurements of swelling and trismus were made before and after lower third molar removal by the lingual split technique, in a series of 53 patients. No single cause of these surgical sequelae was identified and the duration and pattern of both swelling and trismus were recorded.
