Craniofacial anatomical risk factors in men with obstructive sleep apnea and heart failure: a pilot study.

Purpose Obstructive sleep apnea (OSA) is complicated with heart failure (HF); however, the reason for this is not well understood. Craniofacial anatomic risk factors may contribute to OSA pathogenesis in HF patients. However, there are no data about cephalometric findings among OSA patients with HF.
