Correlation between upper airway dimension and TMJ position in patients with sleep disordered breathing.

OBJECTIVE

The goal was to perform a 10-year retrospective study on the correlation between sleep disordered breathing (SDB) and upper airway dimensions, as well as the relation between SDB status and TMJ position. The study also examined links between airway dimensions and TMJ position.

METHODS

Patients were categorized into Control (n = 28) or SDB (n = 45). Cone beam (CBCT) data was analyzed using ™.

RESULTS

Although there were distinctive features within the SDB group, these did not show a correlation of significance with airway dimensions. SDB patients were more likely to have their condyles posteriorly seated. Other factors, such as presence of TMD, limited mouth opening, and pain upon palpation of masticatory muscles also significantly affected the TMJ position. Volumetric airway analysis showed links to TMJ position.

CONCLUSION

SDB patients have a smaller airway volume and have a significant relationship between airway volume and TMJ position with their condyles seated more posteriorly.
