Transdisciplinary Intervention for Obesity Hypoventilation Syndrome

Following diagnosis, individuals with OHS were counseled on therapeutic options, including CPAP therapy, body weight reduction, or CABS. The final decision was made through a shared decision-making process. The CABS procedure was conducted under general anesthesia and integrated bariatric and multilevel airway surgery within a single operative session. This transdisciplinary approach aimed to address both sleep-disordered breathing and obesity-related ventilatory compromise. A general surgeon performed the bariatric procedure, while an otorhinolaryngologist conducted the airway surgery sequentially during the same operation. For the bariatric component, laparoscopic sleeve gastrectomy (LSG) was the primary procedure, while laparoscopic Roux-en-Y gastric bypass was reserved for individuals with significant gastroesophageal reflux or poorly controlled diabetes. Airway surgery encompassed interventions at the nasal, palatal, and lingual levels.
