Evaluation of vacum bell treatment results in pectus excavatum patient, with 3 dimensional scanner

PE is the most common chest wall malformation, occuring in approximately 1 in every 300 births. PAAG and CT are traditional radiological methods used to support the diagnosis. The aim of this study is to avoid the ionizing effect of radiological methods on the patient by using modern diagnostic technologies. 30 patients with PE diagnosis, seen over 2022-2023 years in Eskishehir Osmangazi University Faculty of Medicine, Policlinic of Pediatric Surgery were included in the study. Deformity measurements of patients diagnosed with PE were taken manually. Then, images were taken from different angles with a digital video camera. İmages were processed with x software to create an isolated body model. 3D images were studied through Meshroom software, Blender and Cura programs. In this study, it was seen that there was a significant difference in the statistical comparison of M and 3D measurements. The process of extracting the 3D model of the images was more reliable in comparison with M measurement. No statistical correlation was found between PE depth and patient age, no significant correlation was found between the improvement rate of the PE depth and its type (symmetrical/asymmetrical). Based on the M and 3D measurement data, it was concluded that the PE depth decreased remarkably in the following months with the use of the VB. İt was statistically seen that regular use of the vacuum bell did not significantly affect the decrease in pectus excavatum depth. 3D optical surface scanning is an attractive and promising imaging technique to determine the severity of PE without exposure to ionizing radiation.
