Removal of a Deeply Impacted Ectopic Mandibular Third Molar through a Buccal Corticotomy in Severe Trismus-A Case Report

Management of deeply impacted mandibular third molar in itself is a surgical challenge and when it is associated with restricted mouth opening, it becomes more devious job. Deeply impacted tooth can be approached by buccal corticotomy/osteotomy, lingual split, extraoral approach or sagittal split ramus osteotomy. In patients with restricted mouth opening, options get limited to buccal corticotomy and extraoral approach. Extraoral approach is not a preferred option pertaining to scar formation and potential risk of injury to the marginal mandibular branch of the facial nerve leaving buccal corticotomy as most viable option.
