ShikaniTM Seeing Optical Stylet-aided tracheal intubation in patients with a large epiglottic cyst

Large epiglottic cysts can block the glottis,leading to serious consequences.This condition presents a challenge in terms of airway management for anesthesiologists during induction of anesthesia.We report the use of a ShikaniTM Seeing Optical Stylet combined with a Macintosh laryngoscope to aid tracheal intubation in seven patients with large epiglottic cysts.Use of this technique can avoid cyst rupture and allow smooth,safe intubation.
