We designed a prospective study with the objective to evaluate the efficacy, indications and our experience of submental intubation in different types of maxillofacial surgeries. From May 2008 to August 2010, 23 patients with different conditions were intubated by submental route of tracheal intubation and patients were evaluated on different parameters during and after surgery to find its efficacy, indications and utilization in maxillofacial surgeries. All the patients were managed well with this technique of intubation with no significant difference in intubation and extubation time. We did not face any uneventful complication. There was only one reported complication that is rupture of the bulb of cuffed flexometallic tube but was managed well by changing tube. We found skull base access surgery as a new indication for submental intubation. The submental route for endotracheal intubation may be utilized as an alternative to blind nasal intubation or tracheostomy in the surgical management of patients involving complex maxillofacial surgeries. We hypothesized that the submental intubation should not be used where long term ventilation support is needed. We did a technique modification to deliver the endotracheal tube out from the submental region to avoid pilot cuff damage. Our study proposes that skull base access surgery is a safe and potential indication for submental intubation. In our experience submental intubation is a simple, secure and effective procedure for operative airway control in major maxillofacial surgeries.
