Introduction/Context/Diagnosis
Objectives: Analyzing a patient’s nasal anatomy and airway space is valuable for orthodontics and anesthesiology and is possible using CBCT images captured for orthodontic treatment planning. Here, we developed and tested a novel protocol for measuring airway features along the inferior nasal passage in pre and post CBCT images of patients who received conventional orthodontic treatment. We aimed to determine if there were significant differences in the airway measurements between the two time points for each patient using this novel protocol. Methods: In this retrospective longitudinal observational study, CBCT images of each patient at two time points (T1 and T2) were oriented in Dolphin Imaging, focusing on ANS and PNS as the vertical and horizontal alignment landmarks, and then registered on the cranial base. The registered images were opened in ITK-SNAP for simultaneous measurements taken at the same CBCT slice. Using a novel protocol to measure nasal anatomy and airspace, 12 different measurements were taken across the anterior, middle, and posterior regions of the inferior nasal cavity for each image. We used SPSS to perform paired student t-tests for comparison of T2-T1. Results: The sample had an average age of 27.2 years (STD 8.89) with an average total treatment time of 20.7 months (STD 5.08). None of the 12 measurements in the 3 regions showed statistically significant differences between T2-T1. Conclusions: We developed a protocol for measurement that provided consistent data acquisition across the patient images. We found no statistically significant differences between airway measurements between the two time points. Future Directions: This study represents a bridge for applications such as determining optimal airway preparation for nasal intubation and examining the impact of orthodontic treatment on the nasal cavity's hard and soft tissue architecture.
