Piezotome Versus Surgical Bur: Which is More Effective in Reducing the Postoperative Pain and Edema Following Open Sinus Lift Surgery?

OBJECTIVE: The aim of this study was to compare the piezotome versus surgical bur on postoperative edema and pain following open sinus lift surgery.
MATERIALS AND METHODS: This was a double-blinded split mouth randomized clinical trial. The subjects who were candidates for bilateral open sinus lifting in the posterior maxilla were included in this experiment. Each maxillary side was assigned randomly to one group, piezosurgery or surgical diamond bur for sinus lifting. Postoperative pain and edema were evaluated on the second and seventh days after the surgery, using the VAS scale. Data were analyzed by SPSS software.
RESULTS: In this study, 20 subjects including 10 females (50%) and 10 males (50%) with a mean age of 50.87 ± 9.04 years participated. The mean duration of surgery in piezosurgery (240.13 ± 49.5 s) was significantly higher than the surgical bur technique (135.07 ± 43.53 s) (P < 0.001). Pain and edema were significantly decreased on the seventh day postoperatively compared to the second day in both group (P < 0.05). Pain and edema were similar between the two study groups on the second and seventh days after surgery.
CONCLUSION: The results of this study depicted that the piezosurgery clinical outcomes were similar to surgical bur following open sinus lift surgery. © The Association of Oral and Maxillofacial Surgeons of India 2020.
