Severity bands (0–8 low, 9–16 intermediate, ≥ 17 high) are provisional and not validated; they are shown for description only. The DISE score is a research tool and does not replace clinical judgement.

How the score is calculated

The DISE score is the sum, over the four VOTE levels, of the degree of collapse (0 none, 1 partial, 2 complete) multiplied by a configuration-specific severity weight.

Score A = (Vdegree × Vconfiguration) + Ovalue + Tvalue + (Edegree × Econfiguration)

LevelRulePoints
Velumdegree × 1 anteroposterior, 2 lateral, 3 concentric0–6
Oropharynxlateral only: fixed values 0, 4 (partial), 6 (complete)0–6
Tongue baserecoded value 0, 2 (partial), 3 (complete)0–3
Epiglottisdegree × 2 anteroposterior or floppy, 3 lateral0–6

Score B differs only at the tongue base: the value (2 or 3) is multiplied by a tissue factor of 1 for lymphoid (lingual tonsil hypertrophy) and 2 for muscular (hypotonic or hypertrophic) collapse, so that score B exceeds score A by 2 or 3 points in muscular collapse and equals it otherwise. When the tongue base collapses and the tissue type is unknown, score B cannot be computed.

Worked example: V2c O2 T1 E0 = (2 × 3) + 6 + 2 + 0 = 14 points (score A), or 16 points (score B) if the tongue-base collapse is muscular.
