Facilitation of endotracheal intubation using a bougie in a patient with unilateral vocal cord due to a traumatic thyroid cartilage fracture

Endotracheal intubation of patients with abnormal upper airway structures is rare. In these pa­ tients, 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.
