The document describes a grading system for tonsil size from T0 (no tonsils) to T4 (tonsils kissing in the middle) and grades for oropharyngeal anatomy including types A through E for soft palate and uvula measurements and types 1 through 3 for the Malampati tongue grading system based on how much of the uvula and base of the tongue are visible.

1. Tonsillar Size
 T 0
 T 1
 T 2
 T 3
 T 4
 Absent
 Anterior pillars
 Beyond pillars
 Touching uvula
 “Kissing” tonsils

2. T0 No Tonsils

3. T1 Anterior Pillars

4. T 2 Beyond Pillars

5. T3 Touching Uvula

6. T4 Kissing Tonsils

7. Oropharyngeal grading
 Type A soft palate > 50 mm
 Type B uvula > 11 mm long
 Type C uvula > 10 mm wide
 Type D redundant posterior pillar
 D1 anterior and posterior pillars parallel
 D2 web like posterior arch
 D3 uvula emerges from anterior arch
 D4 uvula emerges from posterior arch
 Type E arch configuration
 E1 narrowing < 20 mm
 E2 posterior arch <15 mm
 E3 posterior arch / pharyngeal wall < 5mm

8. Tongue Grading
(Malampati grading)
 Grade 1
 Grade 2
 Grade 3
 Tip of uvula
 Base visible
 Uvula invisible

9. Malampati 1

10. Malampati 2

11. Malampati 3
