- TC Erciyes University
- Brief Summary
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.
- Detailed Description
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.

Group Intervention Description Lindeman Conventional BSSO were performed with Lindeman and round bur Bone scalpel Bone Scalpel BSSO were performed unilaterally using an ultrasonic bone scalpel
- Primary Outcome Measures
Name Time Method Cutting Time during procedure Length of cutting time was considered the time from the beginning the sagittal osteotomy to the end of making the vertical osteotomy line. The right and left side recorded separately.
neurosensory disturbance up to six months Neuro sensory disturbance between the mental foramen and lower lip region on each side was evaluated subjectively after the operation day to a week. The examiner was blinded, and do not know which side of the mandible was randomly allocated to the experimental treatment.that was recorded by visual analog scale( VAS)
- Secondary Outcome Measures
Name Time Method The splitting time during procedure this is recorded for the right and left sides to determine the difficulty of splitting, respectively. If the time required to complete the splitting was less than 100 seconds, it was determined as 'easy,' between 100-200 seconds as 'medium'; if more than 200 seconds, it was determined as 'difficult.'
postoperative edema up to six months The authors used the 3dMD imaging system (3dMD, Atlanta, GA) and 3dMD Vultus software to evaluate the amount of postoperative edema. Three-dimensional images were taken at maximum intercuspation when the lips were free and the eyes were open. The images were taken at 3 days, and at 6 months after surgery.
The length of the procedure during procedure this is recorded from mucogingival incision to the sagittal splitting in minutes by an unbiased researcher. The reason for determining this period is that the amount of mandibular movement and the degree of fixation difficulty vary, especially in facial asymmetric patients.
The pattern of the split during procedure this is evaluated by cone-beam computed tomography that is classified into four types according to lingual split scale of Plooij et al
