Research Article: Characteristics and Mechanism of Upper Airway Collapse Revealed by Dynamic MRI During Natural Sleep in Patients with Severe Obstructive Sleep Apnea
Introduction:
Obstructive sleep apnea (OSA) is characterized by repetitive collapse of the upper airway during sleep, resulting in hypopnea or apnea. , The primary etiologies of OSA are thought to be linked to abnormal upper airway anatomy and reduced neural control of pharyngeal muscles, – leading to dynamic collapses of multiple patterns. – Surgical intervention is one of the main interventions for OSA. However, the selection of surgical approaches is influenced significantly by various clinical factors, such as the pattern…
