Abstract

Background and Objective: Elongation and calcification of the stylohyoid ligament complex (SLC) which might be correlated with Eagle’s syndrome could cause facial pain or dysphasia. The aim of this study was to investigate the prevalence of stylohyoid ligament complex elongation by panoramic radiographs of patients.
Subjects and Methods: Radiography samples during 2012 and 2013 (396 patients) were inspected from the Radiology Department of Faculty of Dentistry at Ahvaz Jundishapur University of Medical Sciences. The calcified stylohyoid ligament complexes were measured from the cranial base up to the osseous tip of each process. Mineralization of the complex at 25 mm length on the radiograph was considered to be normal while more than this length was taken as ossification of stylohyoid ligament
Results:  Stylohyoid ligament ossification was observed in both sexes, but it was more prevalent in men (72.1%) than women (66.2%) (P<0.05). The calcified stylohyoid ligament complexes were found in 272 out of 396 (68.7%) patients, with an average length of 36 mm. The elongation of bilateral ligaments was found in 63.4% of cases. The difference in average length of SLC was not meaningful for all age and sex groups except for the age group of 55 years old  in female at right side (p<0.05).
 
Conclusion: The elongation of calcified stylohyoid ligament complexes is prevalent in Ahvazian population (68.7%) and is more prevalent in men than women.
