Orofacial Myology
Therapy that helps with the movement, endurance, strength, and coordination of facial muscles (lips, jaw, tongue) that may be impacting oral rest posture, chewing, swallowing, breathing, dentition, and speech.
Orofacial myology is a specialised area within speech therapy that focuses on the function of the facial muscles (lips, jaw, tongue). The term “orofacial” refers to the mouth and face, while “myology” refers to the study of muscles. In orofacial myology, therapists work with individuals to improve the function and coordination of these muscles to address issues related to speech, swallowing, chewing, breathing, oral rest posture, and even the alignment of teeth (dentition).
Orofacial Myofunctional Disorders (OMDs) are when there are problems with the function of the muscles in the face, mouth, tongue, and jaw.
When someone has an OMD, it can affect these things in different ways:
- Speech – OMDs can make it hard to pronounce certain sounds or words because we need sufficient muscle movement and coordination of the lips, tongue, and jaw during speech.
- Swallowing – People with OMDs might have trouble swallowing food or liquids properly due to an abnormal swallowing pattern (e.g., tongue-thrust swallow). This can lead to choking or even problems with digestion.
- Chewing – OMDs can make chewing difficult or uncomfortable because of issues with jaw stability or strength.
- Breathing – Sometimes, OMDs can affect how someone breathes. They might breathe through their mouth instead of their nose, which can cause problems with airflow and even affect their overall health.
- Dentition (Teeth Alignment) – The muscles in the face and mouth also play a role in how the teeth align. OMDs can sometimes lead to issues like crooked teeth or bite problems.
Therapists in this field assess and treat various orofacial myofunctional disorders (OMDs), which can include problems with speech sound production, swallowing difficulties (e.g., tongue thrust), dentition (crowded teeth and crooked bites), improper tongue posture, mouth breathing, sleep disordered breathing, and other issues related to the muscles of the mouth and face.
Signs You May Have an Orofacial Myofunctional Disorder:
– Mouth breathing
– Tongue-tie
– Malocclusion and narrow palate
– Thumb sucking or pacifier use
– Slow speech progress
– Drooling
– Poor sleeper
– Behavioural issues
– Messy or fussy eater
– Allergies
Possible Causes of Orofacial Myofunctional Disorders:
-Low tongue resting position
-Poor lip closure
-Tongue thrust swallow pattern
-Tongue -tie
-Nasal or airway obstruction
-Malocclusion
-Jaw structure (e.g., high narrow palate)
-Use of dummies, thumb sucking, bottles, sippy cups
OMDs can impact several aspects of a person’s daily life, from how they communicate to how they eat and breathe. Treatment typically involves exercises and techniques designed to strengthen or retrain the muscles to function more effectively over time. This may include exercises to improve tongue placement, lip movement, chewing, swallowing, and breathing patterns. By addressing these underlying muscle issues, orofacial myology aims to improve overall speech clarity, swallowing and chewing function, nasal breathing, facial and dental growth, and oral rest posture.
