Resumen
Craniocervical posture can interfere directly on the mandibular and hyoid bone
position as well as on the masticatory and swallowing functions. On the other hand a
stomatognathic alteration such as temporomandibular disorder (TMD) can be a
harmful factor on the alimentaires functions. This study aimed to investigate the
craniocervical posture and TMD relation on the masticatory and swallowing functions.
70 women were divided according to TMD diagnostic evaluated by the Research
Diagnostic Criteria (RDC/TMD): 34 with TMD and 36 without signs and symptoms of
TMD. Craniocervical posture and mandibular and hyoid bone variables were
measured by cephalometric analysis. Masticatory and swallowing function evaluation
was performed according to a protocol of orofacial myofunctional evaluation with
Scores (OMES). It was observed significant correlations between craniovertebral
angle and hyoid bone position variables: linear distance from the hyoid bone to the
menton (p=0,02) and to the mandible (p=0,03). The angle which measured the
anterior position of the head also demonstrated a significant correlation with the
linear distance between hyoid bone and jaw (p=0,00). Degree of cervical curvature
showed a correlation between the linear distance from hyoid bone to the third
cervical vertebra (p=0,01). An important craniocervical postural change was
observed in the group although there was no association between them and a higher
frequency of atypical behaviors evaluated during masticatory and swallowing
functions. TMD subjects showed a significant difference on tongue (p=0,03) and lip
(p=0,04) posture during swallowing. Chronic unilateral chewing pattern was also
observed in the TMD group (p=0,03). In spite of the anatomical relation between
craniocervical posture and mandibular and hyoid bone position it was not possible to
confirm that the postural alterations observed could be associated to damages on
masticatory and swallowing functions. Nonetheless, TMD presence resulted on a
higher frequency of myofunctional alterations during these functions.
