Handheld blue light three-dimensional (3D) scanner versus lateral cephalometry for facial morphology assessment in obstructive sleep apnoea participants : Handheld blue light three-dimensional (3D) scanner for facial morphology assessment of obstructive sleep apnoea participants

PURPOSE: The main purpose of this study is to evaluate the facial morphology of obstructive sleep apnoea (OSA) individuals by using a handheld blue light three-dimensional (3D) scanner (HBL-3DS) in comparison to conventional lateral cephalometric radiography (LCR). Moreover, our research question is to explores the correlation between 3D facial and neck measurements with OSA indices, encompassing the hypoxic burden.

METHOD: This prospective cross-sectional study included forty-four adults with OSA. We compared three measurements between LCR and HBL-3DS images: modified facial profile angle (MFPA), nasolabial angle (NLA), and mandibular length (ML). Additionally, the 3D images of thirty-four participants with OSA indices were analysed for seventeen parameters, such as angles, ratios, and linear distances.

RESULTS: This study revealed significant strong correlations (p
