The Mallampati classification is a bedside airway assessment based on visibility of oropharyngeal structures with the mouth open and tongue protruded. It helps estimate potential intubation difficulty and supports pre-anesthetic planning.
Formula: Mallampati class is a visual airway grade from I (best view) to IV (poorest view).

Higher Mallampati classes indicate less oropharyngeal visibility and increased potential for difficult direct laryngoscopy.
Use this tool during pre-anesthesia airway evaluation, pre-procedure sedation planning, and perioperative difficult-airway preparation.
Mallampati has inter-observer variability and limited standalone predictive accuracy. It should not be the sole determinant of airway strategy.
For related assessments, see ASA Class, RCRI Score and ECOG Status.
