Mineralization of the stylohyoid-stylomandibular ligament complex. A radiographic incidence study.
In this Veterans Administration-based study, 1,771 oral panoramic radiographs were reviewed to detect abnormalities in the styloid process, stylohyoid-stylomandibular ligament complex. Three hundred twenty-three (18.2 percent) of the radiographs revealed mineralization in these areas which varied from an apparent elongation of the styloid process to extensive involvement of the entire ligament complex with segmentation, nodularity, and the development of jointlike structures. Mineralization was unilateral in 12.4 percent of patients and was observed more commonly in patients 50 to 59 years of age. No relationship could be established between the extent of mineralization and increasing patient age. This study suggests that mineralization of the stylohyoid complex is not uncommon and probably only rarely causes symptoms.
