ObjectivesTo compare 1) temporomandibular joint (TMJ) mobility between subjects a) with and without reduced upper cervical spine (UCS) mobility and b) with and without TMJ osseous osteoarthritic-like changes; and 2) UCS osseous changes between subjects a) with and without TMJ osseous osteoarthritic-like changes and b) with and without reduced UCS mobility.Study design39 subjects without pain from TMJ and UCS including 15 women (26-72 years, mean 56.0) and 24 men (27-71 years, mean 49.8) with obstructive sleep apnea (OSA) comprised the patient population. The range of motion (ROM) of the mandible and UCS was assessed clinically. Osseous changes of the TMJ and UCS were assessed by cone beam computed tomography. Differences were tested and adjusted for age and gender by multiple linear and logistic regression analyses.ResultsThe mandibular ROM was within normal range (45-64 mm) but the UCS ROM was reduced in 15 subjects. Osseous TMJ and UCS changes were both found in 38.5% of the subjects. Osseous UCS changes were more frequent in subjects with than without TMJ changes (P=0.0003; Odds Ratio (OR) 21.9). No other significant results were found.ConclusionsThe present findings in OSA patients of co-morbid osseous changes support a possible biomechanical relationship between the TMJs and UCS.
