The goal of this study is to investigate the efficacy of a safety-zone that is anatomically landmarked on the face of patients with mandibular fractures that are approached transbuccally (through cheek) on postoperative intactness of facial nerve.
Healthy patients (American Society of Anesthesiologists Class I)
Patients with mandibular fracture that require open reduction and internal fixation with miniplates and screws.
Mandibular fractures that couldn't be accessed transorally only.
Non-comminuted fractures
Patients with neurological disorders.
Patients who take nerve-supporting supplements (such as Vitamin B12 or Vitamin B complex) prior to surgery.
Presence of facial laceration.
Infected fractures
Parallel
Landmarking Safety-zone
Procedure/SurgeryA safety-zone triangle for transbuccal incision is encased between three lines: the first is a line drawn from the ear tragus to the facial notch. The second is drawn from the outer eye canthus to the mandibular angle. The third is on the lower mandibular border.
Postoperative Facial Nerve Affection Using Sunnybrook Facial Grading System (in numbers from 0 to 100)
Facial nerve function is tested after surgery through subjective facial expressions by the patient and judged by two different investigators grading them on Sunnybrook Facial Grading System
