Lower Vestibular Incision: A Modified Technique of Dissection

Introduction: Exposure to anterior mandible via conventional approach by either cervicular or vestibular incision is normally carried out for trauma or orthognathic surgery. Transection of mentalis muscle and reposition of the muscle is a key step. This prevents post-operative lip ptosis. Material and methods: A modified dissection technique is presented in the article to identify the bilateral mentalis muscles at its insertion and isolate it in order to preserve it if feasible for access or to transect it after demarcating so that it can be reoriented in its native position. Conclusion: The modified method is an anatomically direct functional approach to the anterior mandible.
