Aim: The styloid process (SP) is often considered elongated when it is longer than 33 mm. The aim of this study is to assess the prevalence of the elongated styloid process (ESP) among dental patients and the role of dental pathology as a possible etiological factor. Materials and Methods: In total, 2000 consecutive panoramic radiographs of normal people were retrieved from the College of Dentistry, Ajman University, Ajman, UAE, during the 2-year study period. Two calibrated observers evaluated the radiographs to minimize interobserver bias and error. A caliper was used to measure the length (in millimeters of the ESPs directly on the radiographs from the caudal margin of the tympanic plate to the tip of the SP). The ESP was considered present when the measurements were ≥30 mm. Results: This study indicates that the prevalence of the ESP was about 6.9% among the patients who attended the dental school clinic. Of the 2000 panoramic radiographs reviewed, ESP could be measured in 100 cases at least on one side. There was a significant difference between distributions on the left and right sides. The distribution also depends significantly on age and gender. The incidence of related symptoms was higher than that reported in previous studies. Conclusions: The incidence of ESP among dental patients was estimated to be 6.9%, more prevalent among the elderly compared to the young people and bilateral. Odds ratio (OR) in favor of developing ESP in males is 2.378 times more than that in females. In contrast, the OR in favor of having unilateral ESP in males is less than that in females by 0.284.
