Ultrasonic Bone Scalpel in BSSO

Does Ultrasonic Bone Scalpel Improve Surgical Outcomes in SSRO?

The conventional saw compared with the piezo surgery in BSSO to evaluate cutting time, surgery duration, amount of bleeding. The purpose of this study was to answers following clinical questions: Is ultrasonic bonescalpel effective osteotomy like conventional bur in BSSO? and 2) Does it reduce operative parameter like bleeding, duration, lingual split pattern? 3) Does it reduce postoperative morbidity after BSSO.

The purpose of this study was to answers following clinical questions:

1) Is ultrasonic bonescalpel effective osteotomy like conventional bur in BSSO? 2) Does it reduce operative parameter like bleeding, duration, lingual split pattern? 3) Does it reduce postoperative morbidity after BSSO. Hypotheses of this study that ultrasonic bone scalpel can improve BSSO and its postoperative results due to strong cutting efficiency and soft tissue protective effect.

Surgical procedure; After removing the full thickness mucoperiosteal flap lingula was localized. In ultrasonic device group, osteotomies one side of the mandible were performed unilaterally using an ultrasonic bone scalpel (BoneScalpel; Misonix, Farmingdale, NY) with a serrated standard blade. In conventional group, contralateral side mandibular osteotomies were performed with Lindeman and round bur. Groups are selected randomly.

c- Follow up

The predictor variable was the type of instrument used for bone osteotomy. The instruments were ultrasonic bone scalpel and Lindeman bur. The main outcome variable are the cutting time and NSD. All patients were followed for 6 months.The authors used the 3dMD imaging system (3dMD, Atlanta, GA) and 3dMD Vultus software to evaluate the amount of postoperative edema.
