Objective: Limited data suggests a smaller, narrow maxilla can lead to a decreased oropharyngeal volume (OPV). However, past studies have used 2-dimensional (2D) lateral cephalometric radiographs. The specific aim of this study is to assess how maxillary arch parameters relate to oropharyngeal volume calculated from 3D cone beam computed tomography (CBCT) images. An additional aim was to compare these dimensions in a group of African-American patients with obstructive sleep apnea (OSA) with a group of healthy controls. Methods: 16 full head CBCT images in the closed mouth anatomic head position were obtained from adult male African-American patients with a diagnosis of OSA. The OPV was measured by counting corresponding voxels that are digitally isolated from the 3D CBCT images after segmentation. The same volume axial plane images were used to measure intercanine width, intermolar width, arch length and arch perimeter. In addition, 16 control CBCT images were obtained from adult male African-American patients matched for age with no prior diagnosis of OSA. Each of the maxillary arch parameters was tested for correlation to oropharyngeal volume and compared between the two groups. Results: Reliability was tested and for all parameters the intraclass correlation coefficient was greater than 0.95 (0.97-1.00). The OSA group was significantly older than controls (31.9±6.9, 41.3±11.3 years respectively). After accounting for multiple comparisons the minimum cross sectional area (MINXA) was the only parameter significantly different between groups (p=0.0014). MINXA was found to be a good-excellent predictor of OSA (Receiver operating characteristic curve area under curve =0.89). A cutpoint of 111mm2 was determined for MINXA between groups. Conclusion: The CBCT based imaging analysis produces reliable measurements for all parameters. The current finding suggest that maxillary arch width and length do not contribute to a smaller oropharyngeal airway. MINXA is a good-excellent predictor of OSA in African American adult males.
