Seshagiri Rao Mallampati (1941 – ) Indian born American anesthesiologist.
Eponymously affiliated with the Mallampati Score used to predict the ease of endotracheal intubation
Mallampati encountered a patient whose trachea was difficult to intubate despite optimal positioning, equipment and with an anatomically normal head and neck. Further evaluation revealed the uvula and faucal pillars and were concealed by the base of the tongue.
Mallampati then made it his practice to see wether the faucial pillars and uvula were visible in every patient. He found that the clinical sign of the concealment of the uvula and faucial pillars by the base of the tongue was helpful in predicting the majority of difficult tracheal intubations. He later hypothesized and verified that this in a study published in 1985, dividing the patients into 3 classes, with Dr. Samsoon and Dr. Young’s addition of the 4th class in the Mallampati scoring system.

Mallampati Score (1985)
The Mallampati Score is a grading system based on the visualisation of the pharyngeal structures during laryngoscopy. A study of 210 patients confirmed the degree of difficulty in seeing three pharyngeal structures (uvula, soft palate and faucial pillars) as an accurate predictor of difficulty when using direct laryngoscopy.
If the base of the tongue is disproportionately large relative to the capacity of the oropharynx, it would obscure the view of the faucial pillars, posterior part of the uvula and eventually the soft palate in that order. It would also render the angle to the trachea more acute and obscure the larynx – this anatomical relation was hypothesised by Mallampati and verified with his study published in 1985
