Open Mouth Posture: A Key Symptom of Orofacial Myofunctional Disorders and the Role of Myofunctional Therapy

MyoCorrect Myofunctional Therapy Open Mouth Posture

Orofacial Myofunctional Disorders (OMDs) are a group of functional conditions related to the muscles and functions of the face and mouth. Among the various symptoms of OMDs, open mouth posture is one of the most noticeable and potentially impactful. This article delves into the nature of open mouth posture, its connection to OMDs, and how myofunctional therapy can offer a beneficial treatment approach.

Understanding Open Mouth Posture

Open mouth posture refers to the habit of keeping the mouth open in a resting state, instead of having the lips gently closed. This posture can lead to a range of problems, including breathing issues, sleep disturbances, and even alterations in facial growth and development. The natural resting position should involve lips sealed, teeth slightly apart, and the tongue resting on the palate, facilitating nasal breathing.

Connection to Orofacial Myofunctional Disorders

OMDs encompass a variety of dysfunctions related to the tongue, lips, and jaw. These disorders can affect breathing, swallowing, speech, and even the alignment of teeth. Open mouth posture is often a symptom of OMDs and can be a result of factors such as:

  1. Tongue Tie: A restricted lingual frenulum can limit tongue movement, contributing to an open mouth posture.
  2. Enlarged Tonsils or Adenoids: These can obstruct the airway, forcing mouth breathing.
  3. Habitual Mouth Breathing: Often develops due to chronic nasal obstruction.
  4. Weak Orofacial Muscles: Poor muscle tone can lead to difficulty in maintaining a closed-mouth posture.

Impact of Open Mouth Posture

The implications of an open mouth posture extend beyond mere aesthetics. It can influence oral health, leading to dry mouth and increased risk of dental decay. Furthermore, it can affect the development of the jaw and face, potentially resulting in long-term orthodontic issues. More importantly, it can compromise breathing efficiency, particularly during sleep, and may contribute to sleep-disordered breathing, including obstructive sleep apnea.

Myofunctional Therapy: A Path to Improvement

Myofunctional therapy is a specialized therapeutic approach focusing on improving the tone and function of the orofacial muscles. It involves a series of exercises that target the muscles of the mouth, face, and tongue. The primary goals of myofunctional therapy in addressing open mouth posture are:

  1. Strengthening Muscles: Enhancing the tone of the orofacial muscles to maintain a proper mouth closure.
  2. Correcting Tongue Posture: Training the tongue to rest on the roof of the mouth, facilitating nasal breathing.
  3. Promoting Nasal Breathing: Developing a habit of breathing through the nose, which is healthier and more efficient.
  4. Improving Swallowing Patterns: Ensuring a proper swallow that supports the correct tongue and jaw position.

Open mouth posture is a significant symptom in the spectrum of Orofacial Myofunctional Disorders. It not only signifies underlying dysfunctions but also contributes to a host of other health and developmental issues. Myofunctional therapy offers a promising, non-invasive treatment option, focusing on retraining the muscles and functions of the orofacial region. By addressing the root causes of open mouth posture, myofunctional therapy can significantly improve overall orofacial health, breathing, and quality of life.
