Figure 5. Comparison of radiation doses and SA scores between good prognosis and poor prognosis trismus groups.

Figure 5

A significant difference is noted in the mean dose of masticator structures (p = .04; Fig. 5a), mean dose of masticator muscles (p = .05; Fig. 5b), mean dose of lateral pterygoid muscles (p = .04; Fig. 5c), mean dose of parotid glands (p = .01; Fig. 5c), the product of the six month SA score with mean masticator muscles dose (p = .04; Fig. 5d) and the twelve month SA score (p = .01; Fig. 5e). (MP: medial pterygoid muscle; LP: lateral pterygoid muscle; Temp: temporalis muscle; TMJ: temporomandibular joint; PG: parotid gland; SA score: signal abnormality score; GP: good prognosis; PP: poor prognosis).
