 Nasotracheal intubation is a technique used to provide a secure airway for patients who cannot be intubated using traditional oral or orapharangial routes. This technique involves passing a tube through the patient's nose into their trachea. Nasotracheal intubation can be beneficial in certain situations where other forms of intubation may not be possible due to the patient's anatomy or medical condition. The procedure requires specialized equipment and training, but it can be a life-saving measure when necessary. This article was authored by Dongho Park, Chee Un Lee, Chung Young Jong and others.
