Does Orthognathic Surgery Cause or Cure Temporomandibular Disorders? AÂ Systematic Review and Meta-Analysis

Orthognathic surgery caused a decrease in TMD symptoms for many patients who had symptoms before surgery, but it created symptoms in a smaller group of patients who were asymptomatic before surgery. The presence of presurgical TMD symptoms or the type of jaw deformity did not identify which patients' TMDs would improve, remain the same, or worsen after surgery.
