Orofacial Myofunctional Disorders

Oromyofunctional Disorders

Orofacial myofunctional disorders (OMDs) are defined as functional disorders of the face, mouth, nasopharynx, and oropharynx. This includes oral resting postures of the lips, tongue and jaw, breathing postures, chewing, swallowing, non-nutritive chewing and sucking, and articulation placement.

Most OMDs are multifactorial in origin and are the consequence of a sequence of events or lack of intervention at critical periods resulting in malocclusion and suboptimal craniofacial development.
