Tracheotomy and nasogastric tube insertion were not performed during the treatment. The patient was able to eat orally without choking the first day after surgery, and the symptom of dyspnea was significantly improved. Laryngoscopy showed no recurrence of pharyngeal stenosis 3 weeks after operation (Fig 3). At follow-up six months after the surgery, his parents reported that breathing problems had disappeared and slurred speech had improved.
