Submental intubation in complex craniomaxillofacial trauma.

The submental route for endotracheal intubation is an alternative to nasal intubation or tracheostomy in the surgical management of patients with complex craniomaxillofacial injuries. The critical indication for submental intubation is the requirement for intraoperative maxillomandibular fixation (MMF) in the presence of injuries that preclude nasal intubation and in a situation where a tracheostomy is not otherwise required. MMF to re-establish dental occlusion is essential for a normal functional result in dentate patients with fractures involving alveolar segments of the jaws. However, MMF precludes orotracheal intubation. Nasotracheal intubation is often used but is contraindicated in the presence of skull base fractures and will interfere with the access to certain fracture types. A tracheostomy has a high potential complication rate and in many patients, an alternative to the oral airway is not required beyond the perioperative period. A submental intubation has been used in 11 selected cases amongst 190 consecutively treated patients with craniomaxillofacial trauma over a 3-year period. These cases have been retrospectively reviewed and there have been no significant complications. The indications and technique used are described. Submental intubation is a simple and useful technique with low morbidity in selected cases of craniomaxillofacial trauma and the author's clinical experience with this technique is described.
