Head and neck surgeries usually require nasal intubation, which allows leeway for operative maneuvering in the mouth, pharynx, larynx, and neck. Previous studies have found that the right nostril is more appropriate for nasal intubation using direct laryngoscope or videolaryngoscope. It has been shown that the optical rigid stylet was also an appropriate tool for nasal intubation. However, nasal intubation with rigid optical stylet is technically different from that with laryngoscope. It is unknown whether the choice of nostril could affect the intubation using rigid optical stylet. The main aim is to determine which nostril is more suitable for nasal intubation with video rigid stylet.
To determine which nostril is more suitable for nasotracheal intubation with video rigid stylet.
