Table 2.

Dietary restrictions in relation to trismus severity. There is a statistically significant difference (p < 0.0001) and negative correlation (r = − 0.27) indicating that severity of trismus is correlated more dietary restrictions. MIO: no trismus = 3 fingers, mild/moderate trismus = 2 fingers, severe trismus = 1 finger width or less

Regular, no restrictions (n = 358)	283 (47%)	75 (31%)	0 (0%)
Regular, liquid assist (n = 326)	231 (39%)	89 (37%)	6 (25%)
Solid with restriction (n = 145)	70 (11%)	66 (27%)	9 (38%)
Pureed/non-chewable (n = 4)	3 (1%)	0 (0%)	1 (4%)
Liquid (no solids) (n = 12)	4 (1%)	5 (2%)	3 (13%)
