The aim of this study is to evaluate the prevalence of the elongated styloid process in panoramic radiographic exams, in a subpopulation of northern Brazil in relation to age, sex and side. Panoramic radiographs were selected, and the apparent size of the styloid process was measured from the point where the styloid leaves the tympanic plate to the tip of the process. The data were analyzed using chi-square tests and variance analysis with a 5% significance level. Approximately 30% of the elongated styloid process was observed in patients between 18 to 35 years. Of the styloid processes that measured more than 30 mm (elongated), 764 styloid processes (81%) showed Type I elongation pattern, 97 styloid processes (10%) showed Type II calcification patterns, and 85 styloid processes (9%) showed Type III calcification patterns. The prevalence of the elongated styloid process was high, and no statistically significant correlation was found between the presence of the elongated styloid process and the variables studied.Keywords: Bone Lengthening.

ResumoO objetivo deste estudo é avaliar a prevalência do processo estilóide alongado em exames radiográficos panorâmicos, em uma subpopulação do norte do Brasil em relação à idade, sexo e lado. Radiografias panorâmicas foram selecionadas, e tamanho aparente do processo estilóide foi medido a partir do ponto em que o estilóide deixa a placa timpânica até a ponta do processo. Os dados foram analisados por meio de testes qui-quadrado e análise de variância com nível de significância de 5%. Aproximadamente 73% do processo estilóide alongado foi observado em pacientes entre 18 e 53 anos (p |
