Sinusitis diagnosticada por tomografía computarizada multicorte y su asociación con las variantes anatómicas del complejo ostiomeatal. Hospital José Carrasco Arteaga. Cuenca 2017

Abstract

Background: The anatomical variants of the paranasal sinuses have been considered as a predisposing factor for sinus disease, especially if they involve the drainage route at the level of the osteomeatal complex. The importance of diagnosing them in tomographic studies is that this condition can lead to inadequate management in patients with recurrent sinusitis and increase the risk of surgical complications. Objectives: To determine the prevalence of Sinusitis diagnosed by multislice computed tomography and its association with the anatomical variants of the osteomeatal complex in the imaging area of the José Carrasco Arteaga Hospital in 2017. Method and technique: A transversal, analytical study was carried out in 341 patients who met the inclusion criteria. The information was collected using a form prepared according to the research variables. The data was tabulated with the SPSS v20.0 software. The study population was characterized by descriptive statistics and the association of the variants was established by bivariate analysis and logistic regression model. The ethical rules were respected. Results: the mean age was 45,11 ± 15 years, the prevalence of sinusitis diagnosed by tomography reached 68,04%, the maxillary sinus was the most affected with 42,67%, regular mucoperiosteal thickening was the most common tomographic finding in 53,96% of cases, the septal deviation was the most common anatomical variant with 68,04%, followed by the middle pneumatized turbinate with 9,38%, Haller cell with 7,33%, abnormal unciform process in the 5,57%, ethmoidal bula with 4,69% and Agger Nasi cells 2,64%. A statistically significant association was found between sinusitis and Haller's cell, ethmoid bula, middle pneumatized turbinate and abnormal unciform process (p <0.05), especially if they compromise the drainage route
