A study on the styloid process in panoramic radiographs / 대한구강악안면방사선학회지

ABSTRACT

PURPOSE: To find statistically based information about the natural variation in the length of the styloid process and to show the influence of the gender and age on the length of the styloid process. MATERIALS AND METHODS: 1, 300 panoramic radiographs were retrieved from inactive files at the Dental Hospital of Kyung Hee University. Measurements of the length of the styloid process were made directly on the radiographs from the inferior margin of the tympanic plate to the tip of the styloid process. RESULTS: The mean length of 948 styloid processes was 25.2 mm +/- 6.6. The median was 24.5 mm, and the interquartile range was 7 mm. The mean length was 25.7 mm for male and 24.6 mm for female. All percentile was greater for male than for female. The median is 25 mm for male and 24 mm for female. CONCLUSION: This study suggests that the difference of the styloid process length between genders was statistically significant and the length of styloid process was significant increased with age until 30 years.
