ABSTRACT

Introduction: The paranasal sinuses are regions with great anatomical variability. Due to the current boom that functional sinus surgery represents, it is important to know the anatomical variations, dimensions and volumetry of the structures that constitute the paranasal sinuses in the mestizo population. Objective: To describe the prevalence in computed tomography of the main anatomical variants of the paranasal sinuses, as well as their dimensions and volumetry in a sample of a Mexican mestizo population. Material and methods: Cross-sectional, descriptive and prospective study based on an imaging review of the paranasal sinuses of 186 cases, carried out at the ISSSTE "General Ignacio Zaragoza" Regional Hospital. The data analysis consists of measuring the three axes of each sinus to calculate its area, statistical analysis of the dimensions and standard deviation. The prevalence and percentage of the most common anatomical variants were obtained. Statistical analysis to obtain mode, median, average and standard deviations, was performed with SPSS. Results: The dimensions and volume of the paranasal sinuses were obtained. As well as the prevalence of anatomical variants, distance from the nasal spine to sphenoid structures, insertion of the uncinate process, height of the ethmoid roof and variants of the sphenoid sinus. Comparative tables were made with similar studies. Conclusions: It is important to identify anatomical variants to perform a safe surgery. Analyzing the computed tomography, allows us to recognize the dimensions and variants of the structures involved in surgery.
