Context: The styloid process is a cylindrical bony outgrowth located in front of the stylomastoid foramen and it extends from the temporal bone outward. Elongation of the styloid process may be responsible for the irritation of a number of structures coursing through the parapharyngeal space. The styloid process presents with varied morphology. Aims: This is a study carried out to analyze the prevalence of various morphological patterns of the styloid process in South Indian population. Subjects and Methods: A total of 1200 digital panoramic radiographs were analyzed for the morphological assessment of the styloid process. The types and the pattern of calcification were determined based on the classification proposed by Langlais et al. Statistical Analysis Used: Cross tabulation using SPSS version 16. Results: Among the types of the styloid process, elongated type was the most common type present on both the sides. Among the patterns of calcification, completely calcified was the most common type observed, followed by calcified outline pattern. Conclusions: It is important for the clinicians to be aware of the variations seen in the morphological pattern of the styloid process as panoramic radiograph is a routine screening radiograph. Our study contributes to the literature, adding important information about the diversity of the styloid process in the South Indian population.
