Anatomical Remodeling of the Upper Airway after Laparoscopic Sleeve Gastrectomy: A Multimodal Assessment of Structural and Functional Improvements in Obstructive Sleep Apnea

Obstructive Sleep Apnea (OSA) represents a significant global health challenge, closely linked to obesity and a heightened risk for cardiovascular and metabolic disorders. Continuous Positive Airway Pressure (CPAP) remains the cornerstone of OSA management; however, its effectiveness is often hindered by patient adherence and tolerance. Metabolic and bariatric surgery (MBS) has emerged as a viable alternative by reducing excess weight and improving upper airway anatomy. Among the various MBS techniques, Sleeve Gastrectomy (SG) has gained prominence due to its favorable outcomes and limited complications. This study aims to assess the impact of SG on OSA, utilizing Magnetic Resonance Imaging (MRI) and polysomnography to analyze structural changes and clinical outcomes.
