The primary cause of an orofacial myofunctional disorder (OMD)

January 2022

The primary cause of an orofacial myofunctional disorder (OMD) is an open mouth posture or mouth breathing due to nasal structural obstructions and allergies.

It is often difficult to identify a single cause for an orofacial myofunctional disorder. Most disorders involve a combination of factors that may include:

  • Nasal airway interference from enlarge tonsils or adenoids, allergies or anatomical deviations involving the nasal cavity or pharynx.
  • Improper oral habits such as thumb or finger sucking, cheek or nail biting, teeth clenching or grinding.
  • Structural or physiological abnormalities such as short lingual frenum (tongue-tie)
  • Hereditary predisposition to any of the above factors.

Nasal airway interference – mainly Allergies – are the primary cause of OMDs.

When a person exhibits a mouth breathing posture or chronic open mouth posture, it is important to determine if this posture is a habit due to past upper respiratory problems or if there are currently unresolved nasal airway concerns. The only professionals that can determine if you are able to breathe nasally consistently are ENTs and Allergists. Therefore, a referral to an ENT and Allergist is imperative.

Since nasal airway problems are the primary cause of an Orofacial Myofunctional Disorder (OMD), it is important to be evaluated by an ENT to rule out nasal structural obstructions such as enlarged tonsils and adenoids and an Allergist to rule out environmental airborne allergens.

Nasal airway problems are the CAUSE and the Orofacial Myofunctional Disorder (OMD), dental malocclusion  and articulation (speech) disorders are the RESULT.

It is well known that nasal airway problems are a the primary cause of an orofacial myofunctional disorder (OMD), so recognizing the signs of sinusitis is important.

Sinusitis in Texas (and the rest of the United States) is a common problem. The Centers for Disease Control estimates that more than 29 million Americans suffer from chronic sinusitis.

Remarkably, that’s nearly 13 percent of the entire population.

We hear you asking, “What is sinusitis?”


Does Orofacial Myofunctional Therapy Really Work?

January 2017


As an IAOM Certified Orofacial Myofunctional Therapist specializing in orofacial myofunctional therapy (or what has been referred to as “tongue thrust therapy”) since 1977, I get asked everyday,”Does Orofacial Myofunctional Therapy really work?”

The answer is, “Absolutely!”

I think the best way to demonstrate proof of how Orofacial Myofunctional Therapy (OMT) really works is to show the long term results of Orofacial Myofunctional Therapy (OMT) through photographs of my patient’s teeth.


Orofacial Myofunctional Disorders and Otolaryngologists

September 2016


I am proud to share the publication of an article I co-authored with Dr. Robert Mason, Emeritus Professor of Surgery and Previous Chief of Orthodontics at Duke University Medical Center, entitled,”Orofacial Myofunctional Disorders and Otolaryngologists”. The purpose of the article is to alert otolaryngologists to Orofacial Myofunctional Disorders (OMDs) and their primary causes of airway interference including allergies. An understanding of the variety of OMDs should facilitate improved communications between otolaryngologists and IAOM Certified Orofacial Myologists since Orofacial Myofunctional Therapy will not be successful without the resolution of airway interference.
