Clinical Definition

Mandible characteristics:

  • Lower Jaw: Movable portion of the jaw
  • Facial Support: Provides structural support for lower face
  • Dental Support: Holds the lower teeth
  • Muscle Attachments: Attachment site for chewing and airway muscles
  • Airway Influence: Position affects upper airway dimensions

Mandibular size and position significantly influence upper airway space, with retrognathia (receding mandible) being a major risk factor for sleep apnea.

Etymology & History

The mandible has been recognized anatomically since ancient times, with its role in sleep apnea becoming understood with the development of oral appliance therapy and orthognathic surgery.

Reference Values & Interpretation

Normal Values

Normal mandibular anatomy should provide adequate support for the tongue and maintain appropriate upper airway dimensions.

Abnormal Values

Abnormal mandibular anatomy may include retrognathia, micrognathia, or asymmetry that reduces upper airway space and increases sleep apnea risk.

How It's Measured

Mandibular anatomy is assessed through physical examination, lateral cephalometry, CT imaging, and dental evaluation for treatment planning.

Role in Diagnosis

Mandibular assessment is crucial for sleep apnea diagnosis and treatment planning, particularly for oral appliance therapy and surgical interventions.

Role in Treatment

Mandibular anatomy can be addressed through oral appliance therapy (advancing the mandible) or orthognathic surgery (maxillomandibular advancement).
