The primary objectives are to evaluate the safety, effectiveness, stability, ease of use, and patient comfort of the GMA LMA, providing practical guidance for clinical airway management. Additionally, this research will analyze the anatomical positioning and sealing mechanism of the LMA to identify factors influencing proper alignment and airway sealing. The findings may contribute to future improvements in LMA design, enhancing patient safety and procedural success.\n\nThis study is designed for healthcare providers, anesthesiologists, and researchers seeking evidence-based recommendations for LMA selection in clinical practice.
