  • Abstract:
  • The laryngeal mask airway (LMA) is a widely used supraglottic device, but successful insertion requires optimal depth of anaesthesia to suppress airway reflexes, traditionally achieved with propofol or sevoflurane. Despite advancements in second-generation LMAs, insertion success remains assessed through subjective criteria (jaw relaxation, coughing, patient movement), leading to high rates of undetected malposition (50–80%) and inconsistent clinical outcomes. This comparative study aims to evaluate sevoflurane versus propofol for LMA insertion conditions in adults using an objective, computer vision–based measurement of chin-throat angle change after jaw thrust, moving beyond traditional subjective scoring. By quantifying insertion conditions with higher precision, this study seeks to identify which anaesthetic agent provides superior LMA insertion conditions and to establish a reproducible, technology-enhanced assessment method for clinical practice and future research.
