Randomized clinical study comparing piezosurgery and conventional rotatory surgery in mandibular cyst enucleation.
OBJECTIVE
The aim of the present study is to compare piezoelectric surgery to the conventional rotatory surgery in mandibular cyst enucleation, and to determine the 2 method's suitability and the postoperative outcomes.


METHODS
Eighty patients were included in the study. 35 male and 45 female, which showed cystic mandibular lesions, compared with the inferior alveolar nerve or the mental nerve. The patients were randomly divided into two groups. In the test group, cystectomy was performed using conventional rotatory instrumentation (rotatory-group), and in the other one piezoelectric surgery (piezo-group). The swelling was documented 24/48/72 h and 1 week post-surgery and the patients recorded their subjective postoperative pain daily for 7 days using a Visual Analog Scale (VAS).


RESULTS
Patients treated with piezoelectric technique have presented a lower VAS, minor swelling and less recovery time compared to the rotatory-group. No lesions of the mandible nerve were detected with piezosurgery whereas surgery with rotary instruments resulted in 8% hypesthesia at least up to one week.


CONCLUSIONS
The results of this study suggest that piezosurgery may be considered effective in cyst enucleation compared to traditional procedures with burs, since it grants the patients significantly less post-surgical pain and swelling.
