ABSTRACT 

Introduction and Objectives: The mean radiographic length of the styloid process has been reported to be between 20 to 30 mm. Although the reason for its variable development is not clear, elongation of the styloid process is recognized as one of the numerous causes of pain in the craniocervical region. Length of the styloid process in the Nepalese population has not been carried extensively to date. With this in mind our study aims to measure the length of styloid process on panoramic radiographs and determine the variation in age, sex and sides of the elongated styloid process.

Material and methods: A total of 200 digital panoramic radiographs which were available as soft copies in the department of Oral and Maxillofacial Radiology, Chitwan Medical College, were selected for the study. The unpaired t test, and two-way ANOVA were used for statistical analysis.

Results: Elongated styloid processes were present in 36% of the panoramic radiographs. The mean lengths of the elongated right and left styloid processes were 33.57 ± 6.02 mm and 36.21 ± 6.47 mm, respectively and the difference between them was statistically significant. Mean length of the right and left side styloid processes in males was 33.37±6.5 mm and 36.41±7.3 mm, whereas in females it was 34.24±6.24 mm and 37.01±6.12 mm respectively.

Conclusion: Elongated styloid process is frequently seen in the elderly population with no correlation to gender.

Key words: Elongated styloid process, panoramic radiography, Age group.
