Maxillomandibular Deficiency
A complex condition we routinely treat, maxillomandibular deficiency is highly correctable with outcomes that enhance facial support, airway space, and overall function.
What Is Maxillomandibular Deficiency
Understanding Maxillomandibular Deficiency
Maxillomandibular deficiency is a skeletal condition in which both the upper and lower jaws are underdeveloped and positioned posteriorly, often with inadequate vertical height as well. This combined anteroposterior and vertical deficiency affects facial projection, occlusion, airway volume, and overall facial support. Treatment typically involves coordinated orthognathic surgery to advance and appropriately reposition both jaws in three dimensions, restoring facial balance, functional occlusion, and airway capacity.

Common Functional Issues
Eating
Reduced projection of both jaws can limit bite efficiency and overall chewing function.
Speech
Speech clarity may be affected due to limited support for proper tongue and lip positioning.
TMJ
Joint strain may occur due to underdeveloped jaw structure and compensatory function.
Mouth Breathing
Decreased airway space can increase reliance on mouth breathing, particularly during sleep.
Nasal Congestion
Airway restriction may contribute to reduced nasal airflow and potential sleep-related breathing issues.
Psychosocial Effects
A recessed facial profile with reduced lip support and overclosed appearance can affect appearance and confidence in social settings.

BILATERAL SAGITTAL SPLIT OSTEOTOMY
Advances and downwardly repositions the lower jaw to improve projection, bite alignment, and facial balance, typically coordinated with upper jaw surgery.

LE FORT I OSTEOTOMY
Advances and downwardly repositions the upper jaw to enhance support, projection, and occlusal alignment.
Double Jaw
DOUBLE JAW SURGERY
Both jaws are advanced and downwardly repositioned together, to maximize airway and functional improvement.
