Current perspectives in intra operative airway management in maxillofacial trauma.

OBJECTIVE: Maxillofacial trauma presents a complex problem due to the disruption of normal anatomy. In such cases, we anticipate a difficult oral intubation that may hinder intraoperative IMF. Nasal and skull base fractures do not advocate use of nasotracheal intubation. Hence, other anesthetic techniques should be considered in management of maxillofacial trauma patients with occlusal derangement and nasal deformity. This study evaluates the indications and outcomes of anesthetic management by retromolar, nasal, submental intubation and tracheostomy.
METHODOLOGY: Of the 49 maxillofacial trauma cases reviewed, that required intraoperative IMF, 32 underwent nasal intubation, 9 patients had tracheostomy, 5 patients utilized submental approach and 3 underwent retromolar intubation.
RESULTS: Among patients who underwent nasal intubation, eight cases needed fiberoptic assistance. In retromolar approach, though no complication was encountered, constant monitoring was mandatory to avoid risk of tube displacement. Consequently, submental intubation required a surgical procedure which could result in a cosmetically acceptable scar. Though invasive, tracheostomy has its benefits for long term ventilation.
CONCLUSION: Intubation of any form performed in a maxillofacial trauma patient is complex and requires both sound judgement and considerable experience.
