Downfolding of the epiglottis into the laryngeal inlet after tracheal intubation using the McGRATHTM MAC videolaryngoscope: a case report.

Background: Downfolding of the epiglottis into the laryngeal inlet is considered to be a rare complication of tracheal intubation. We describe a case of epiglottic downfolding during tracheal intubation using a McGrath videolaryngoscope (McGRATH^TM MAC). Case presentation: A 44-year-old female was scheduled for breast reconstruction surgery. Intubation was performed using a McGrath videolaryngoscope. After intubation, videolaryngoscopy revealed that the epiglottis was inverted and folded down into the laryngeal inlet. We elevated the larynx anteriorly using the McGrath videolaryngoscope, enabling the downfolded epiglottis to be pulled out from the laryngeal inlet and restored to its original position. After surgery, the patient was extubated without any complications. Conclusions: When using the McGrath videolaryngoscope, both glottic exposure similar to that achieved with the Macintosh laryngoscope and careful observation of the epiglottis should enable the prevention, detection, and treatment of epiglottic downfolding into the laryngeal inlet.
