The<unk>  is assessed by asking the patient, in a sitting posture, to open their mouth and to protrude the tongue as much as possible. The anatomy of the oral cavity is visualized; specifically, the assessor notes whether the base of the uvula, faucial pillars (the arches in front of and behind the tonsils) and soft palate are visible.<unk> ng is generally done without phonation. Depending on whether the tongue is maximally protruded and/or the patient asked to phonate, the<unk> ng may vary. Modified<unk> ng: * Class I: Soft palate, uvula, fauces, pillars visible. * Class II: Soft palate, major part of uvula, fauces visible. * Class III: Soft palate, base of uvula visible. * Class IV: Only hard palate visible. Original<unk> ng: * Class 1: Faucial pillars, soft palate and uvula could be visualized. * Class 2: Faucial pillars and soft palate could be visualized, but uvula was masked by the base of the tongue. * Class 3: Only soft palate visualized. Further research may be needed to determine the most effective consistent and predictive approach on which to standardize<unk> ng.
