Outline of Final Research Achievements	The purpose of this research is to create a three-dimensional volume data of the normal nasal sinus and diseased sinus, and to establish the evidence of optimization of endoscopic nasal surgery.We created the normal sinus model and two cases of septal perforation patients.Preoperative patient, performs comparison of the post-operative state, after the piercing closure and observed a decrease in stress concentration, and was restored to normal air flow conditions.The change in the air flow before and after surgery in one case to quantify, paper has already been published.Further piled up cases in the future, it is planned to integrate the data.
