Accuracy of using the antilingula as a sole determinant of vertical ramus osteotomy position.

Purpose: The antilingula is an important landmark in mandibular ramus surgery. Its relationship to the lingula provides useful clinical information as to the position of the mandibular foramen and inferior alveolar nerve. The purpose of this study was to determine the reliability of using the antilingula as a guide to osteotomy placement for intraoral vertical ramus osteotomies.
