PROBLEM TO BE SOLVED: To provide a system for supporting diagnosis of nasal and sinus diseases. A method of generating a learning model for a system that supports the diagnosis of nasal and sinus diseases includes a step of acquiring a CT image including a maxillary sinus, a frontal sinus, a lamina sinus, and a butterfly bone sinus, and the CT. Regarding the image, the partitioning step of partitioning the areas of the maxillary sinus, the frontal sinus, the anterior sinus, the posterior sinus, and the butterfly sinus into five, and the size of the five divided regions, The relationship with the area size of what was formed inside the five regions was quantified, and the difference between the bone around the maxillary sinus on one side and the bone around the maxillary sinus on the other was quantified. For each of the above, a quantification step for quantifying the shading, interview data corresponding to the CT image, quantification by the quantification step, and data for nasal and sinus diseases corresponding to the CT image. Is included as the teacher data, and includes a learning process for learning the relationship between the CT image and the nose and sinus diseases. [Selection diagram] FIG. 18
