Overview of Laryngeal Masks
Laryngeal masks were invented in 1981 by Dr. Archie Brain as an alternative to endotracheal intubation for managing the airway during surgical procedures under general anesthesia. Since their introduction, laryngeal masks have revolutionized airway management worldwide. Some key facts about laryngeal masks include:

- Global Laryngeal Mask create a seal around the laryngeal inlet without requiring placement through the vocal cords like endotracheal tubes. This allows ventilation of the lungs without risking damage to the vocal cords.

- The original and most widely used laryngeal mask is the Classic Laryngeal Mask Airway. It features a curved tubular shaft connected to an elliptical latex cuff at one end that seals in the laryngeal inlet.

- Several other laryngeal mask designs have been developed with improvements in features like size options, drainage ports, fiberoptic capabilities, and ease of insertion. Popular models include the ProSeal, Supreme, and i-gel.

- Laryngeal masks are typically inserted blindly without requiring visualization of the vocal cords like endotracheal intubation. This allows for faster and easier placement by non-anesthesiologists.

- Compared to face masks, laryngeal masks offer a more reliable seal around the airway without the risks associated with endotracheal intubation in select patients and surgical procedures.
