Abstract Background Closed rhinoplasty techniques are gaining popularity once again as more and more patients demand. The use of piezo electric devices (PEDs) is also another popular practice in rhinoplasty surgeries recently to reduce postoperative edema and bruising. Objectives The aim of this study is to propose a new technique in which all osteotomies in closed rhinoplasty surgeries can be performed using PEDs. Methods A comparison was made between 274 patients who underwent closed piezo rhinoplasty (CloPi) and 120 patients who underwent closed rhinoplasty using conventional osteotomy. In the CloPi technique, all osteotomies, including lateral and transverse osteotomies, were performed with PEDs using straight and 90-degree curved tips. Preoperative and postoperative results obtained with the Rhinoplasty Outcome Evaluation (ROE) questionnaire were compared to evaluate aesthetic and functional results. Results In the CloPi group, the mean age was 30.8 years (18-60 years) and the mean follow-up period was 19.6 months, while in the control group, the mean age was 33.5 years (18-61 years) and the mean follow-up period was 29.3 months. Significantly better results were obtained in the ROE questionnaire compared to preoperative values in both groups (p 0.001). When comparing the postoperative–preoperative change in ROE scores between the two groups, the improvement observed in the CloPi cohort was significantly greater for all items (p 0.001), except for Question 2—assessing the ability to breathe—where no significant difference was detected (p = 0.231). Conclusions Closed piezo rhinoplasty (CloPi) is an easy and reliable technique in which all osteotomies can be performed with PEDs. Successful surgical results can be achieved with wide surgical dissection.
