Resumo
Introduction: Minimally invasive approaches are increasing in popularity. We have undertaken an anatomic and radiological study of the frontal sinus that is frequently involved in the super-cilliary minicraniotomy used to access the parasellar region.Objective: We wanted to evaluate the prevalence and morphological characteristics of the frontal sinus in a certain population sample.Methods: 98 randomly assigned individuals were subjected to CT examinations. the antero-posterior diameter, sagittal diameter, transverse diameter and total volume of the frontal sinus were calculated.Results: the frontal sinus tended to be larger in males than in females with the exception of the transverse diameter (p < 0.10).Conclusion: Knowledge of the anatomic variations of the frontal sinus is important in surgical approaches through the superciliary arc in order to avoid complications such as infections and CSF fistula.
