Summary

Laryngeal masks are core devices for supraglottic airway management, and the accuracy of their anatomical position directly impacts ventilation safety and the incidence of complications. Despite their wide clinical application, gaps remain in understanding their in vivo anatomical characteristics. This study aims to evaluate the in vivo anatomical features (e.g., insertion depth, anatomical alignment, tissue compression) of three laryngeal masks (LMA Supreme, I-gel, GMA-Tulip) using CT scanning in anesthetized patients undergoing CT interventional therapy, providing anatomical evidence for optimized laryngeal mask selection and complication prevention.

Conditions

  • Supraglottic Airway Device

Interventions

DEVICE

GMA-Tulip

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.

DEVICE

I-gel

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.

DEVICE

LMA-Supreme insertion

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.
