Разработка и применение алгоритма создания 3D-модели околоносовых пазух носа для изучения гидродинамики ирригационной терапии

Purpose. To elaborate an algorithm for creating a full-size 3D model of the paranasal sinuses, and to evaluate this model effectiveness in use for studying irrigation therapy hydrodynamics. Materials and methods. The study consisted of 2 stages. The initial data for the first stage of the study were CT scans (n=12), computer programs InVesalius 3.1 and Meshmixer, and photopolymer resin eSUN Standard. At the 2nd stage of the study, the effectiveness of using the elaborated 3D model was assessed. To analyze the effectiveness of using the resulting 3D model for studying hydrodynamics of two types of irrigation therapy, the recorded video of procedures was evaluated and Likert scale scores were assessed. Results. An algorithm for creating a 3D model of the paranasal sinuses was elaborated, and hydrodynamics of irrigation therapy was studied. When assessing the sum of Likert scale scores, a reproducibility factor of 0.92 was obtained, and the mean category rank demonstrated the overall positive attitude of the expert group toward the 3D model, thus confirming its effectiveness for use in planning patients’ irrigation therapy. Conclusion. An algorithm for creating a 3D model of the nasal sinuses was elaborated, allowing effective study of irrigation therapy hydrodynamics. Analyzing and selecting the most rational irrigation therapy option should be performed using an individual 3D model of the paranasal sinuses.
