An in Vivo CT Imaging Study of GMA-Tulip, I-gel, and LMA Supreme (GLAM-II)

Under general anesthesia, GMA-Tulip laryngeal mask is inserted following standardized protocols. CT scanning and fiberoptic laryngoscopy are performed to assess insertion depth, anatomical alignment, and tissue compression.

Under general anesthesia, I-gel laryngeal mask is inserted following standardized protocols. CT scanning and fiberoptic laryngoscopy are performed to assess insertion depth, anatomical alignment, and tissue compression.

Under general anesthesia, LMA Supreme laryngeal mask is inserted following standardized protocols. CT scanning and fiberoptic laryngoscopy are performed to assess insertion depth, anatomical alignment, and tissue compression.
