Maxillofacial Injury Severity Score (MISS) and FOMDA Score

The Maxillofacial Injury Severity Scale (MISS) is based on the RFISS and 5 possible functional derangements.

FOMDA:

(1) facial deformity (F)

(2) open degree (O)

(3) malocclusion (M)

(4) diplopia (D)

(5) age (A)

MISS =

= (RFISS) * (F + O + M + D + A + 1)
