Evaluation of patients' perceptions of alterations after chin bone graft harvesting.

OBJECTIVE

To evaluate patients' perceptions of alterations occurring after chin bone harvesting.

MATERIALS AND

METHODS

Thirty patients were evaluated subjectively by visual analog scale-related sensitivity, facial aesthetics, eating, speaking, and lower lip movement, during 12 months. Objective analysis used the static light touch neurosensorial test. The statistical analysis was executed with Friedman test with P < 0.05 for both samples.

RESULTS

Subjective analysis revealed no alterations (1) to facial aesthetics, eating, speaking or lower lip movement but sensitivity of the mental region went from a lot of alteration initially (5) to little at the end of the study (3). Objective analysis results showed normal sensitivity (1) in the region after 12 months.

CONCLUSION

The discrepancy between subjective and objective analyses may be indicative of the limited precision of clinical testing for subjective impressions assessment.
