Objective:

To investigate the efficacy of sleeve gastrectomy (SG) in alleviating symptoms of obstructive sleep apnea (OSA) and assess both structural and functional improvements using MRI and polysomnography (PSG).

Key Findings:
  • Significant reduction in OSA severity and improvements in upper airway structure post-sleeve gastrectomy.
  • MRI revealed increased velopharyngeal airway volume and decreased tongue and pharyngeal lateral wall volumes.
  • Postoperative follow-ups indicated improvements in AHI and ODI metrics.
Interpretation:

The study suggests that sleeve gastrectomy leads to both structural and functional improvements in patients with OSA, potentially offering a viable alternative to traditional CPAP therapy.

Limitations:
  • Limited longitudinal imaging studies directly correlating anatomical changes with functional outcomes.
  • Potential biases in patient selection and adherence to follow-up protocols.
Conclusion:

Sleeve gastrectomy may effectively reduce OSA severity through anatomical remodeling of the upper airway, warranting further research to establish long-term outcomes.
