Dev Psychobiol 2021 May 9. Epub 2021 May 9.

School of Psychology, Laval University, QC, Canada.

Estimation of Apnea-Hypopnea Index using Deep Learning on 3D Craniofacial Scans.

IEEE J Biomed Health Inform 2021 May 7;PP. Epub 2021 May 7.

Obstructive sleep apnea (OSA) is characterized by decreased breathing events that occur through the night, with severity reported as the apnea-hypopnea index (AHI), which is associated with certain craniofacial features. In this study, we used data from 1366 patients collected as part of Stanford Technology Analytics and Genomics in Sleep (STAGES) across 11 US and Canadian sleep clinics and analyzed 3D craniofacial scans with the goal of predicting AHI, as measured using gold standard nocturnal polysomnography (PSG). First, the algorithm detects pre-specified landmarks on mesh objects and aligns scans in 3D space. Read More
