Thus, this study aimed to explore factors affecting the efficacy of MMA for OSA using a 3-D morphological and computed fluid dynamics (CFD) analysis of the upper airway (UA).\nDesign: Retrospective study\nSettings and participants: Twenty consecutive patients (six women, mean age 34.2 ± 12.4 years) who underwent MMA because of persistent OSA at our center.\nMain outcome measures: Cone-beam computed tomography images were captured before and after MMA. We assessed the maxilla and mandibular positions, cross-sectional areas of the nasal airway (NA) and pharyngeal airway (PA), and PA space (PAS). The negative pressure of the PA, NA, and UA were measured at inspiration using CFD. We performed paired t-tests and Wilcoxon signed-rank test to compare values before and after MMA. The relationship between the airway size and pressure was evaluated using Spearman correlation coefficients and a non-linear regression analysis.\nResults: PAS significantly expanded from 6.5 ± 3.4 mm to 12.2 ± 3.8 mm. NA obstruction significantly improved from -312.6 ± 265.0 Pa to -76.2 ± 129.0 Pa. Moreover, the patients were divided into four types according to the PAS size and presence of NA obstruction, namely narrow PAS with NA obstruction, narrow PAS, NA obstruction, and wide PAS and without NA obstruction.\nConclusions: We identified variations in the OSA types. However, MMA substantially improved NA obstruction and PA expansion. Thus, we considered that MMA for OSA was effective for various types.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"Sojiro HISAGAI, Kasey K.
