ABSTRACT
The maxillary sinus (MS) is described as a pyramid-shaped cavity of the maxilla. Knowledge of its morphology makes it possible to define normality and abnormality so that its three-dimensional analysis can be a valuable preoperative tool during surgery in this anatomical area. The aim of this study is to present a strategy of morphological analysis of the MS using 3D printing acquired through computed cone beam tomography (CBCT) images. A cross-sectional descriptive study was conducted, including 15 subjects (8 women and 7 men). The 3D virtual reconstruction and modeling was done on the MSs bilaterally, and 30 physical models were produced on a 3D printer. The results revealed that the MSs obtained exhibited various morphologies. An individual analysis of each MS allowed the tripod nature of the MS to be defined. We also were able to observe anatomical repairs such as the MS ostium, as well as complex areas affecting important surgical decisions. This method for creating 3D models of MSs provides a new approach to understanding the precise anatomical characteristics in these structures, which cannot be assessed in the same way on a 2D screen. It may be concluded that 3D printouts of the MS are a suitable method of preoperative analysis that can be useful in educating the patient, however, less time-consuming strategies should be explored.
RESUMEN
El seno maxilar (SM) es una cavidad piramidal en maxila. El objetivo de este estudio es presentar una estrategia de análisis morfológico del SM utilizando impresión 3D a través de la adquisición de imágenes provenientes de tomografías computadorizadas cone beam (TCCB). Se realizó un estudio descriptivo transversal incluyendo 15 sujetos (8 mujeres y 7 hombres). Se realizó la reconstrucción y modelado virtual 3D de los SMs bilateralmente y se obtuvieron 30 modelos físicos generados en una impresora 3D. Los resultados arrojaron que los SMs obtenidos presentaban morfologías variadas, el análisis individual de cada SM permitió definir la condición tripoidal del SM, reparos anatómicos como el ostium del SM, mientras que zonas complejas relacionadas a decisiones quirúrgicas importantes pudieron ser observadas. Este método de creación de modelos 3D de SMs entrega un nuevo enfoque que permite apreciar características anatómicas precisas de estas estructuras, que no se pueden evaluar de la misma forma en una pantalla 2D. Se puede concluir que la impresión 3D de SM entrega un método de analisis prequirúrgico adecuado y que puede ser útil en la educación del paciente; otras estrategias con menor consumo de tiempo deben ser exploradas.
