Endotracheal intubation of patients with abnormal upper airway structures is rare. In these patients, endotracheal intubation may be difficult and sometimes emergent surgical airway security may be required, so a thorough airway evaluation, intubation plan, and implementation should be performed. We report a case of successful endotracheal intubation using bougie in the patient with unilateral vocal cord and narrow glottis who underwent thyroid cartilage fracture 10 years ago.
