Valoración radiológica de las variantes anatómicas de las cavidades paranasales a través de la tomografía computarizada y su relación con la patología rinosinusal en personas en edades comprendidas entre 15 a 45 años atendidos en el departamento de radiología del Hospital Manual Ygnacio Monteros de la ciudad de Loja, durante el periodo de octubre a diciembre del 2013.

This research project was carried out applying the descriptive, quantitative and prospective style. It studied the radiological assessment of the anatomical variants in the paranasal cavities using a computed tomography (CT) and its relation with rhino-sinusal pathology in people between 15 to 45 years old, assisted in the Radiology Department at the hospital “Manuel Ygnacio Monteros” in the city of Loja; from October to December 2013. The Objective, establishing the frequency of anatomical variants in the paranasal cavities by gender, age and relationship to rhino-sinusal pathology (rhinosinusitis). Studies Sinus CT were performed on a 16-slice Helical Tomography, Phillips Brillant brand, with thick slices of 1.0mm, 1mm interval, 120 kV, 200 mAs, FOV 120-180, axial and coronal sections. A survey was used as a tool, so based on this instrument it is possible to conclude that: There is a relation between the anatomical variants of the paranasal cavities and the rhino-sinusal pathology; that, the most common anatomical variants in the paranasal cavities were: From maxillary sinus: septa maxillary 17.64% and hypoplasia with its 11.76%. From ethmoid sinus, Agger Nassi cells 12.06% and Haller cells with 8.62 %. From sphenoid-sinus with degree of pneumatization sellar configuration with a 17.33%. The central provision of the septum bone of sphenoid is 12% and the secondary bone septum 9.33%. In the frontal sinus there is a hypoplasia variant with 21.2%. That the relation between the anatomical variants and the rhino-sinusal pathology prevails: in patients who experienced variations in the degree of pneumatization of sphenoid the 34% of them had rhinosinusitis; Agger Nassi cells 20% of the patients had rhinosinusitis; Haller cells were related to 20% of rhino-sinusal pathology; with frontal sinus hypoplasia 10% showed rhinosinusitis, patients with Onodi cells and maxillary sinus septo had 9% of rhino-sinusal pathology. The relation between the osteomeatal complex (OMC) disease and the rhino-sinusal pathology ensues in 28 of the 75 patients studied, Ethmoid-bulla with 57% of cases and those who had some variation in Hamulus of hamate represent the 36% of cases.
