Relationship Between Mouth Opening and Masseter Elasticity in Oral Cancer

NCT06941727 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 10

No results posted yet for this study

Summary

The study aims to assess the hardness of masticatory muscles in post-surgical oral cancer patients using strain elastography ultrasound, calculating the masseter elasticity index and exploring its association with maximum interincisal mouth opening. Furthermore, the study incorporates exercise training to analyze whether changes in masseter hardness can serve as an objective indicator for predicting the improvement of trismus.
