Submental intubation in complex maxillofacial trauma: Pilot balloon protection.

ABSTRACT

AIMS: This study aims to describe our refined technique of submental intubation to avoid the recorded intraoperative complications related to tube passage and pilot balloon rupture. CASE SERIES This is a retrospective case series of 21 patients with complex maxillofacial trauma who underwent submental intubation from January 2019 to January 2023. All the patients underwent to the same procedure with a new technique of pilot balloon protection the pilot balloon was not deflated because, once the connector was removed, only the tube was curved and passed through the incision extraorally while the cuff remained inflated. The wire of the pilot balloon was passed behind the last tooth so as not to interfere with the maxillary-mandibular fixation, remaining extraorally under the anesthetist's view. DISCUSSION: Only 2 patients (9.5%) reported complications related to submental intubation in particular a patient (4.8%) reported oral floor infection, and in another patient (4.8%) an unesthetic skin scar was observed. No patients reported intraoperative complications related to the procedure. CONCLUSION: The technique of pilot balloon protection that we have proposed seems to be effective in reducing the intraoperative complications related to the passage of the pilot balloon, such as rupture, damage or early extubation.
