Context: Orthopantomograms of different individuals were studied to understand the prevalence of morphological variants in styloid process. New types of styloid processes were identified other than that found in the existing classification while proceeding with the study. Thus, a deeper examination of this topic felt interesting.
Aims: To identify the anatomical variations of styloid process and its distribution according to age and gender on digital panoramic radiographs.
Materials and Methods: A total of 1000 panoramic radiographs from the database were analyzed for the types and distribution. Langlais classification with modification is used for the study.
Conclusion: The tapered and wavy forms were identified apart from Langlais classification of styloid process, in elongated category. Among total population under study elongated category were predominant compared to other types and gender wise distribution manifested the predilection of elongated category among male. Moreover, the elongated variant dominated among the older individuals than adult and younger age groups. Considering age as the parameter Type IV category prevails in younger age group.
Key Messages: 1):The two new morphological variants among the elongated variant of styloid process categorized as tapered and wavy were identified, which is to be included in existing classification. 2): Elongated variant is most predominantly seen, of which tapered variety is common among elongated variety, 86.6% was seen in females and 83.8% was seen in males; 3): Wavy variant was dominant in males with 16.1%, whereas in females it was 13.3%. 4): Contemplation of gender as parameter, manifested male predilection to elongated category. 5): Relatively high prevalence of type IV category was analyzed next to elongated variant among age group upto 20 years.
