Flexible LMAs

Flexible, reinforced LMAs have wire-reinforced, flexible airway tubes with a smaller diameter than other LMAs. These features allow them to be positioned away from the surgical field, which is particularly useful for otolaryngologic, dental, and other head and neck procedures in which the surgeon and anesthesiologist are sharing the airway or the surgical field. Examples include the LMA flexible (A), the Ambu AuraFlex (B), and the Tru-cuff Ultra Flex EX (C).
