The submental approach is used to treat fractures of the anterior mandibular body and symphysis. These fractures can usually be approached and treated intraorally. However, depending on the difficulty or severity of the fracture, and/or the presence of a laceration suitable, an extraoral approach via the submental route may be indicated.
An advantage to this approach is that the surgeon can easily inspect the lingual surface of the mandible to assure optimal reduction of the fracture in this region.
There are no major neurovascular structures in the submental area.
