Soft Palate Injuries during Orotracheal Intubation with the Videolaryngoscope

Abstract

Objective: The videolaryngoscope has gained popularity for providing superior visualization in intubations. A rare complication of this technology is soft palate injury. Through a literature review and case series, we highlight the risks associated with the Glidescope and McGrath videolaryngoscopes and the management of soft palate injuries. Method: A case series of multi-institutional review of medical records was performed to identify patients with soft palate injuries from the videolaryngoscope. A literature review was also performed to analyze risk factors, mechanism of injury, complications, and management of palate injuries. Results: Of 9 cases, 3 resulted in soft palate perforations, which required primary closure. The remaining 6 patients sustained a soft palate laceration, which was treated conservatively. This injury commonly occurs when the intubator is focused on the video monitor and blindly inserts the Glidescope into the oropharynx. The rigid stylet used with the Glidescope increases the propensity for oropharyngeal injuries during blind insertions. Conclusion: Proper training, an awareness of this potential complication, and direct oral cavity visualization are recommended while inserting the videolaryngoscope. Repair is recommended for through-and-through perforations or if a large hanging flap is present. Antibiotics should be considered for lacerations greater than 1 to 2 cm.
