Many discussions on this forum mention changing the hyoid bone position through exercises. The purpose of this post is to summarize what the current scientific literature shows in a neutral, evidence‑based manner.
1. Hyoid Position and Posture
Research indicates that head and neck posture affect the spatial orientation of the hyoid bone relative to craniofacial landmarks. Forward head posture, for example, is associated with altered hyoid angulation in cephalometric imaging.
A published study reports changes in hyoid bone position related to different cervical postures.
This does not imply that the hyoid bone can be repositioned permanently like a limb. Rather, it suggests that postural alignment is correlated with hyoid orientation.
2. Biomechanics of Suprahyoid and Infrahyoid Muscles
The muscles attaching to the hyoid (suprahyoid and infrahyoid groups) change length and activity depending on head and neck position. This relationship has been examined in biomechanical research.
A biomechanics study describes how head flexion and extension alter muscle lengths around the hyoid.

These findings show functional variability, not fixed structural change from simple exercise.
3. Orofacial Myofunctional Therapy
Some clinical work in myofunctional therapy investigates how exercises targeting tongue and orofacial muscles affect hyoid movement patterns. Results vary by study and context.
One trial examined effects of orofacial therapy on hyoid bone displacement vectors.

This evidence relates to functional improvement in swallowing mechanics and muscle coordination rather than dramatic cosmetic repositioning.
4. Practical Interpretation
Based on current literature:
There is no strong randomized controlled trial confirming that exercise alone permanently raises the hyoid bone position in adults.
However, there is evidence that neck posture and muscle function influence the functional resting position of the hyoid and related soft tissues.
5. Exercises with Rationale
The following practices are commonly mentioned in clinical and biomechanical contexts. They may influence muscle tone or posture that is correlated with hyoid position:
Chin Tucks / Cervical Alignment
Performed by gently retracting the head to improve cervical posture. This is supported by general posture research and may influence suprahyoid muscle tension indirectly.
Controlled Jaw Opening Drills
Some swallowing studies use rapid controlled jaw opening protocols to activate suprahyoid muscles. It’s a technique with physiological rationale, though evidence is limited.
Tongue Posture and Swallowing Repetitions
Engaging the tongue against the palate and practicing controlled swallowing strengthens suprahyoid involvement and orofacial coordination.
6. Conclusion
Scientific literature supports the concept that posture and muscle function around the neck influence the biomechanical environment of the hyoid bone, but does not support the idea of moving it permanently like a skeletal repositioning.
If you include posture and muscle coordination work in your routine, it may improve the functional resting orientation of related structures.
What protocols have you personally found effective for neck posture and hyoid‑related muscle function?

Instantaneous head posture (IHP) can extensively alter resting hyoid position in humans, yet postural effects on resting hyoid position remain poorly documented among mammals in general. Clarifying this relationship is essential for evaluating ...
