For nasotracheal intubation, which nostril results in less epistaxis: right or left?: A systematic review and meta-analysis.

Background: Nasotracheal intubation is usually required in patients undergoing oromaxillofacial, otolaryngological or plastic surgery to prevent the airway encroaching into the operating field. Epistaxis is the most common complication, but which nostril is associated with a lower incidence and severity of epistaxis is still unclear.

Objective: When both nostrils are patent, to determine the preferred nostril for nasotracheal intubation under general anaesthesia.
