Summary

This study found that using two mini dynamic compression plates for mandibular angle fractures is easy but unpredictable. Complications like infection and nonunion occurred in 29% of cases, sometimes requiring further surgery.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Trauma Surgery
  • Orthopedic Surgery

Background:

  • Mandibular angle fractures are common facial injuries.
  • Open reduction and internal fixation (ORIF) is a standard treatment.
  • Minimally invasive techniques are being explored for ORIF.

Purpose of the Study:

  • To evaluate the efficacy and complication rates of ORIF for mandibular angle fractures using two mini dynamic compression plates.
  • To assess the need for postoperative maxillomandibular fixation (MMF).

Main Methods:

  • Thirty patients with 31 mandibular angle fractures were treated.
  • Open reduction and internal fixation with two mini dynamic compression plates and self-threading screws.
  • Transoral incision with transbuccal trochar instrumentation.

Related Experiment Videos

  • No patients received postoperative MMF or training elastics.

    • Main Results:

    • Complications requiring secondary surgery occurred in 9 fractures (29%).
    • Early infections (3 cases) required drainage and hardware removal with MMF.
    • One nonunion with malocclusion needed a more rigid plate.
    • Late infections/swelling (5 cases) required plate removal after osseous union.

    Conclusions:

    • The described technique for mandibular angle fracture fixation is relatively easy to perform.
    • However, the treatment approach demonstrated unpredictable outcomes with a significant complication rate.
    • The use of two mini dynamic compression plates without MMF may lead to complications requiring further intervention.
