The Interplay between Tongue Tissue Volume, Hyoid Position, and Airway Patency

The hyoid bone position in mouth breathers and tongue-thrusters.

In 1981 Bibby and Preston commented on the uniqueness of the anatomic relationships of the hyoid bone, notably that it was not fixed in space by bony articulations. This fact alone makes it a potential indicator of certain individual features of importance in orthodontic diagnosis and treatment. This study investigates the effect of mouth breathing and tongue-thrusting on the hyoid bone positio...

The Tongue, Mandible, Hyoid System

The craniocervical-mandibular system works in harmony and allows different functional tasks as the postural control of the cervical region. This system is formed by the temporomandibular joint, the masticatory muscles and ligaments connecting the temporomandibular joint and the cervical region. It has been seen to affect human posture, and many disorders of the temporomandibular joints may affe...

The interplay between morphogens and tissue growth.

Morphogens are conserved, secreted signalling molecules that regulate the size, shape and patterning of animal tissues and organs. Recent experimental evidence has emphasized the fundamental role of tissue growth in expanding the expression domains of morphogens and their target genes, in generating morphogen gradients and in modulating the response of cells to morphogens. Moreover, the classic...

Coupled hard-soft tissue simulation with contact and constraints applied to jaw-tongue-hyoid dynamics

Developmental changes in pharyngeal airway depth and hyoid bone position from childhood to young adulthood.

OBJECTIVE (1) To test the hypothesis that there are no developmental changes in the pharyngeal airway depth and hyoid bone position from childhood to adulthood in normal Taiwanese persons, (2) to identify any sexual dimorphism, and (3) to find the predictive value of selective variables for the hyoid bone position. MATERIALS AND METHODS Lateral cephalometric radiographs of 239 normal Taiwanes...
