Video Laryngeal Mask vs. Endotracheal Tube in Septoplasty
Sponsor: Samsun University
Summary
This single-center, prospective, observational, comparative study evaluated airway management using the SaCoVLM™ video laryngeal mask airway (VLMA) and a conventional endotracheal tube (ETT) in adult patients undergoing elective septoplasty under general anesthesia. The airway device was selected by the responsible anesthesiologist as part of routine clinical practice, without randomization. The primary outcome was airway blood contamination assessed at the end of surgery. Secondary outcomes included hemodynamic responses, ventilation parameters, airway device placement characteristics, recovery time, surgeon satisfaction, and postoperative airway-related symptoms. Distal tracheal blood contamination was assessed using flexible bronchoscopy in both groups. Postoperative sore throat, dysphagia, cough, and hoarseness were evaluated during recovery and at predetermined postoperative intervals. Comparative analyses of postoperative symptoms were limited to the first 12 hours because 24-hour follow-up data were incomplete.

Interventions
Video Laryngeal Mask Airway (VLMA)
The SaCoVLM™ video laryngeal mask airway, a supraglottic airway device with an integrated camera, was used for airway management during elective septoplasty. The integrated camera enabled direct visualization of the glottic inlet and assessment of proximal blood contamination. At the end of surgery, distal tracheal blood contamination was assessed using flexible bronchoscopy in all 32 VLMA patients included in the final analysis, regardless of proximal blood contamination findings. Airway insertion characteristics, ventilation and hemodynamic parameters, recovery outcomes, and postoperative airway morbidity were recorded.
Endotracheal Tube (ETT)
A conventional cuffed endotracheal tube was inserted using direct laryngoscopy for airway management during elective septoplasty. At the end of surgery, the distal trachea was examined for blood contamination using flexible bronchoscopy through the ETT before removal. Proximal tracheal/glottic contamination was assessed indirectly by examining blood around the distal portion of the ETT cuff after aspiration of the posterior oropharynx and extubation. Airway insertion characteristics, ventilation and hemodynamic parameters, recovery outcomes, and postoperative airway morbidity were recorded.
