Mandibular Retrusion

Mandibular retrusion is underdevelopment/retroposition of mandible, causing convex facial profile, Class II malocclusion, and retrognathia, with risk of airway obstruction (OSA). Treatment: growth-modification appliances (headgear/functional appliance) in growing children; orthodontic camouflage in mild; orthognathic surgery (BSSO mandibular advancement) in skeletally mature severe; treat OSA (CPAP/surgery); multidisciplinary; follow-up growth.

Common Symptoms

Convex profile; Class II malocclusion; retrognathia; OSA risk

Causes and Pathogenesis

Congenital/syndromic/habit causes mandibular hypoplasia/retrusion.

Treatment

Growth modification (children); orthognathic surgery (adults severe); treat OSA

Preventive Measures

Early orthodontic evaluation; treat mouth breathing/adenoids.
