ABSTRACT:
A mandibular retractor which is inserted intraorally has a retractor blade shaped to retract the cutaneous region laterally away from the mandible. The retracting blade also has an aperture which allows surgical instruments to be inserted through an incision in the cutaneous region, through the aperture, and to the mandible. The retractor allows a surgeon to retract with one hand and view the surgical site by looking down in to the mouth. The surgeon's other hand is free to operate surgical instruments such as a drill or screwdriver.
