Abstract
At the present, nasal splint models are developed from two sources. The first one is the development from modification of existing domestic medical equipment, and another one is importing from abroad. However, both of them have restrictions on suitability that cause the problem of selecting an appropriate model for each patient. Moreover, there is no existing software or tool to modify 3D nasal splint models at the moment. There are two main problems: 1.) it is hard for a doctor to adjust models to suit a patient's nostrils by using existing modification software, and 2.) there is no software for automatic 3D nasal splint model reshaping. To solve the two main problems of this research, the objectives of this study were to implement the program for automatic 3D reshaping of nasal splint models and to evaluate the developed program. This project aims to construct software to create 3D models of nasal splints. It consists of several functions, such as importing nostril pictures from patients, selecting a model that is almost similar to nostril pictures, drawing line coordinates for automatic modification models, and downloading modified models into the machines. This research focuses on the usability and accuracy of nasal splint models. Therefore, it could become a software application to prepare 3D models, which are compatible with each patient, before surgery. After that, this research experiment was conducted on fifteen volunteers who are selected by doctors of Siriraj Hospital based on the different shapes of the volunteers' noses. The experiment will compare the printed 3D nasal splint model and the real nasal size of the volunteers, then the researcher will interview the doctors to observe the error of the program. The data were collected and analyzed by using a Blender application to measure the output 3D nasal splint and compare the real value of the real nose. Moreover, they are computed to get the difference values and convert them to the error percentage. As there were a lot of data, a standard deviation is introduced to look at the average of each side and the range of error. It was found that the output 3D models had various shapes based on each participant, and there was a little error measurement which occurred from several factors, and to improve this paper in the future, three major aspects can be implemented. The result leads to the conclusion that this project is possible to continue development and is necessary in the surgical and medical fields in Thailand. Implication of the Thesis: In the final stage, this project offers a 3D model of nasal splints based on nasal pictures of patients. However, three major obstacles remain. They are no standalone version, no automatic measurement, and no smoothing process inside the application. Most of the measurement results from the experiment are measured correctly or within the specified limits of error between 0.08 to 0.15 centimeters. It is not more than the limitation of 0.2 centimeters. The main goals of this research, which were addressing the difficulty for doctors to adjust models by using standard modification software and the lack of a program for automatic 3D reshaping of nasal splint models, are fulfilled.
