Orthognathic surgery patients showed similar temporomandibular function to the general population, with reduced mandibular mobility being the most common issue. Most patients experienced no or mild dysfunction after surgery.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthodontics
  • Temporomandibular Joint Disorders

Context:

  • Orthognathic surgery aims to correct significant jaw discrepancies.
  • Evaluating post-surgical temporomandibular function is crucial for patient outcomes.
  • The Helkimo index is a validated tool for assessing temporomandibular joint (TMJ) dysfunction.

Purpose:

  • To assess temporomandibular function in patients post-orthognathic surgery using the Helkimo index.
  • To compare the prevalence of temporomandibular disorders (TMD) in post-surgical patients with a healthy control group.

Summary:

  • A study evaluated 105 patients (average 47-month follow-up) after various osteotomies using the Helkimo index.
  • 82.8% of patients exhibited no or mild temporomandibular dysfunction.

  • No significant difference in TMD prevalence was found between patients and 202 controls, though reduced mandibular mobility was more common in specific dysfunction groups (D II, D III) in patients.

    • Impact:

    • Findings suggest orthognathic surgery has a neutral to positive impact on overall temporomandibular function.
    • Highlights the importance of monitoring mandibular mobility post-surgery.
    • Provides normative data for TMD prevalence in a post-orthognathic surgery cohort.
