The Baska Mask® (Baska Versatile Laryngeal Mask Pty Ltd., Australia) has been designed by Australian anesthesists, Kanag and Meenakshi Baska. It obviates the need of an orogastric tube and replaces this with a sump and two drains. It brings together features of PLMA, SLMA, SLIPA and i-gel. The biggest advantage of Baska mask lies in the fact that cuff deflation or inflation is not required prior to insertion [97].

It is made of medical grade silicone. It differs in several ways from the conventional LMA, including; a cuff-less self-sealing membranous bowl which inflates and deflates with each positive pressure inspiration and expiration respectively, an inbuilt "tab" that permits to increase its angulation for easy negotiation of the oropharyngeal curve during placement, a bite block. It has a dual high flow suction drainage system. The distal aperture at oesophageal end is aspirated using two vents running along the entire length of the stem. One tube is connected to high pressure
