What is this publication about?
The relationship between TMJ disorders and orthognathic surgery remains debated. Dr Jean-Pascal Dujoncquoy (first author) and colleagues at Lille University Hospital surveyed 57 dysgnathic patients on pain, joint sounds, clicking, locking and limited mouth opening.
For colleagues: outcomes
TMJ symptoms were significantly reduced in patients with pre-operative complaints. 80% reported improvement; only 3.6% reported worsening.
Some previously asymptomatic patients may develop TMJ symptoms after surgery — a low but real risk for informed consent. No significant difference was found between Class II and Class III patients.
In plain language
Jaw surgery can relieve jaw joint pain in most patients who already had TMJ symptoms. New symptoms may occasionally appear in previously asymptomatic patients.
