Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthodontics
  • Surgical Complications

Background:

  • Mandibular midline distraction is a surgical technique used to increase mandibular width.
  • Understanding potential complications is crucial for patient safety and treatment planning.

Purpose of the Study:

  • To determine the incidence and nature of complications associated with mandibular midline distraction.
  • To evaluate the safety profile of this surgical method.

Main Methods:

  • Retrospective review of 100 consecutive patient records.
  • Documentation of complications occurring within two weeks post-surgery.

Main Results:

  • 14% of patients experienced complications during the distraction period.

  • Complications included appliance issues (4%), incomplete osteotomy (3%), scar strictures (2%), fractured incisor (2%), abscess (1%), swelling (1%), and gingival recession (1%).
  • Only 3% of patients had irreversible damage.
  • Conclusions:

    • Complications from mandibular midline distraction are infrequent and generally mild or temporary.
    • The procedure demonstrates a relatively safe profile for mandibular expansion.
    • The low rate of irreversible damage supports its clinical utility.
