monitoring
2

Lifestyle modification and dietary intervention

Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.

3

Imaging studies

CT or MRI imaging to fully characterize the bony morphology and assess for associated soft tissue abnormalities affecting swallowing or breathing.

Additional treatment options

Swallowing therapy

Targeted exercises to strengthen suprahyoid and infrahyoid muscle groups that work with the hyoid bone during the swallowing sequence.

Sleep positioning modifications

Elevation of head during sleep and avoidance of supine positioning if structural abnormalities contribute to obstructive sleep symptoms.

lifestyle

Hyoid bone surgical intervention

Procedures such as hyoid myotomy, suspension, or thyrohyoid fusion to enlarge the airway or improve swallowing mechanics in selected cases.
