Investigational drug(s) / intervention(s)

Landmarking Safety-zone

Landmarking Safety-zone: A 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.

Study summary

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.

Accepted
Inclusion Criteria: * 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 Exclusion Criteria: * 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

Primary outcome measure(s)

  • Postoperative Facial Nerve Affection Using Sunnybrook Facial Grading System (in numbers from 0 to 100) — First postoperative week, and third postoperative week.
    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
