Surgical procedures involving the head and neck may require nasotracheal intubation which is more traumatic than orotracheal intubation. Nasotracheal intubation is technically more difficult than oral intubation, but it has few advantages. It is better tolerated by the patient as nasal route increases comfort for the patient and decreases injury/necrosis of tongue and lips; tube fastening is simpler, thus reducing accidental extubation. The patient cannot bite the tube or manipulate it with the tongue, better oral care, easy stabilization and generally easier oral care. Although the incidence of complications after nasotracheal intubation is reported to be variable, the most common one is epistaxis. Other complications include turbinectomy, retropharyngeal laceration/dissection, intracranial placement through basilar skull fracture, and delayed/unsuccessful placement.,, Damage of tube cuff with Magill forceps may be associated with direct vision nasotracheal intubation.
We have used bougie-aided nasotracheal intubation technique using Truview laryngoscope. Nostrils were prepared with oxymetazoline drops, and the patient was placed in the “sniffing” position. After induction of anesthesia and adequate mask ventilation, gum-elastic bougie was inserted in the nostril, and Truview laryngoscope was inserted in the mouth to see the tip of the bougie which needs to cross laryngeal inlet [Figure 1]. Most of the times, bougie may be directed to cross the vocal cords using external laryngeal manipulations, but Magill forceps was used at few occasions. Bougie may get obstructed at anterior commissure which can be taken care by rotating it by 90°–180°. A well-lubricated endotracheal tube (ETT) is threaded over it which was directed forward to cross the glottic opening under vision. The bougie was taken out and cuff inflated. Bilateral chest auscultation and capnography trace were checked before fixing the ETT.

We have used this technique in approximately 900 patients with much reduced risk of cuff injury during nasotracheal intubation.
Nasotracheal intubation can be a potentially traumatic process, and traditionally lower pathway along the floor of the nasal cavity is associated with fewer incidence of trauma., As most of the complications occur during tube advancement through the nostrils and proximal nasopharynx, the complications of both blind and direct-vision nasotracheal intubation are almost the same. However, retropharyngeal laceration and esophageal intubation are more with blind placement, while cuff injury is associated with direct-vision nasotracheal intubation., Lubrication, topical administration of a vasoconstrictor, and thermosoftening of ETTs are some accepted measures to reduce the risk of trauma. In addition, some mechanical techniques have been described to facilitate atraumatic passage of nasotracheal tubes. Kihara et al. reported that epistaxis and postoperative nasal complications were reduced with an expensive, soft- and round-tipped, silicone ETT. Enk et al. reported a reduced incidence of epistaxis using a nasopharyngeal airway as pathfinder during nasotracheal intubation. Here is a newer application of Truview laryngoscope for bougie-aided nasotracheal intubation with reducing the risk of cuff injury and soft-tissue trauma.
We would like to thank patient and theater staff.
