Unilateral hypoglossal nerve palsy after the use of laryngeal mask airway (LMA) protector-a case report-

Abstract

Background: The laryngeal mask airway (LMAⓇ) Protector™ (Teleflex Medical Co., Ireland) is the latest innovation in the second generation of LMA devices. One distinguishing feature of this device is its integrated, color-coded cuff pressure indicator (Cuff Pilot™ technology) which enables continuous cuff pressure monitoring and allows adjustments when necessary; this ensures patient safety due to better monitoring. Case: We report a case of postoperative unilateral hypoglossal nerve palsy after uncomplicated use of the LMA Protector. To the best of our knowledge, this could be the second reported case. Conclusions: This case demonstrates that anesthetists need to routinely measure cuff pressure and that the Cuff Pilot™ technology is not a panacea for potential cranial nerve injury after airway manipulation.
