Management of difficult airway has always been a huge challenge for anesthesiologists. This paper reports a laryngeal stenosis patient who were scheduled for laser laryngeal cavity expansion and reconstruction under a self‑retaining laryngoscope after laryngeal cancer surgery accompanied with tracheotomy and radiotherapy. The surgery was successfully completed through preoperative discussion and close cooperation between anesthesiologists and surgeons using superimposed high frequency jet ventilation (SHFJV). This technique does not require endotracheal intubation, which ensures the ventilation of patients during surgery and provides a good surgical field of vision and a favorable prognosis. This paper discussed and summarized the experience of this case, so as to provide new thoughts for perioperative management of difficult airway.
