It has the advantage of providing exceptional accessibility and optimal working conditions in the oral cavity for surgeons. Anesthesia providers are highly trained in managing and securing the airway. Because the oral intubation route is the most widely used technique for securing the airway, nasal intubation can be cumbersome for anesthetists who do not routinely perform this skill. Moreover, anesthesia providers who do not routinely perform NTI may feel apprehension out of concern for nasopharyngeal bleeding and trauma. The number of dental and oromaxillofacial procedures requiring nasal intubation has been steadily growing annually. Although NTI is generally safe, it still presents a risk for complications. The purpose of this literature review was to examine current literature and evidence-based practices of NTI to determine whether the use of a catheter-guided technique will improve patient care outcomes by way of decreased trauma to the airway compared to current clinical practices. The goal of this review is to recommend the use of a catheter-guided technique for NTI as the preferred method for securing the airway during oral surgery as it is less traumatizing to the airway than conventional methods.展开更多
