Mallampati Score — Difficult Airway Prediction

The Mallampati Score (Modified Mallampati Classification) is a validated 4-class clinical tool for predicting difficult laryngoscopy and intubation by assessing the visibility of oropharyngeal structures. The patient is examined seated with head in neutral position, mouth fully open, tongue protruded maximally, and phonation avoided. The score correlates with the degree of tongue-to-pharyngeal space relationship: Class I = full visualization (easy intubation); Class IV = no oropharyngeal structures visible (potentially difficult intubation). A component of multiple difficult airway prediction tools (e.g., LEMON assessment, Naguib score).
