- Abstract: Objective Summarize the clinical application and elevating the caudal end of suspension laryngoscope to deal with severe glottis exposure difficulties.Method A retrospective analysis was conducted on the clinical data of 25 patients with severe dystotic glottic exposure(Cormack-Lehane grade Ⅲ or Ⅳ)who underwent laryngoscopy support surgery from January 2021 to January 2024,then analyze the intraoperative management and outcomes.Results In all the patients,after the angle of the suspension laryngoscope was adjusted to the maximum and the glottis could not be exposed satisfactorily,the caudal end of the suspension laryngoscope stent was lifted to obtain a larger tilt angle and field of view.After the caudal end of the stent was elevated by(11.50±6.31)cm,the glottis was exposed satisfactorily in 23 cases and the operation was performed successfully;In 2 cases,the laryngeal mask airway was used in conjunction with a fibrolaryngoscope and laryngeal forceps were used to extract the lesion step by step.Pharyngeal mucosal tearing and oozing of blood occurred in 24 cases,and the bleeding stopped after electrocoagulation;one case had loose and dislodged teeth.There were no significant changes in blood pressure and heart rate of patients before and after stent lifting(P＞0.05).Conclusion For the severe difficulty of glottis exposure during suspension laryngoscopic surgery,it can be dealt with by lifting the caudal end of the stent,which is a simple and effective method that does not cause serious complications and is worth clinical application.
