The Pioneers

Seshhagiri Rao Mallampati 1941-


Mallampati was born in Andhra Pradesh India in 1941. He was educated in India and immigrated to the USA in 1971.

Whilst working at the  Brigham and Women's Hospital, he encountered a patient who was difficult to intubate, despite the usual routine of  positioning.

The patient had a normal head and neck. He found that the Tonsils and uvula were concealed by the base of the tongue, Mallampati suggested that this anatomical feature would be sign of a difficult intubation.

He subsequently validated this clinical sign and refined it to the four-grade system that is is now widely used in today's anaesthesia.323
