CONDYLAR ASYMMETRY AND ITS RELATION TO AGE IN A GROUP OF PATIENTS WITH A CRANIOMANDIBULAR DISORDER OF MYOGENOUS ORIGIN

A group of patients with a myogenous origin of craniomandibular disord ers was found to show a variation of condylar asymmetry with age. The curve obtained by plotting patient age against their asymmetry index w as parabolic in nature. This differed from a group of patients with an arthrogenous origin of pain, where a linear correlation with age, wit h a negative slope, had previously been found. The mean asymmetry inde x for this group of patients was found to be 23.77%. This is higher th an that reported for a group of patients with a craniomandibular disor der of arthrogenous origin, namely 18.76%. It appears that these two g roups differ in the variation of condylar asymmetry with age.
