Unlabelled: Previous systematic reviews evaluating piezoelectric osteotomy are of critically low quality. We conducted a high-quality systematic review and meta-analysis to evaluate outcomes for piezoelectric versus conventional osteotomy.
Methods: The study protocol was published a priori (PROSPERO: CRD42021287877). MEDLINE, Embase, Web of Science, and CENTRAL were searched for studies comparing piezoelectric versus conventional osteotomes and reporting at least one outcome of interest (clinical or patient-reported outcomes, PROs). Methodological quality and risk of bias were assessed using GRADE and Cochrane's RoB-2/ROBINS-I tools, respectively. Random effects models were applied.
Results: Of 347 articles, 10 studies (nine randomized controlled trials; one prospective cohort study) including 554 patients were included. Piezoelectric osteotomy was associated with significantly reduced edema [standardized mean difference (SMD), -0.67; 95% confidence interval (CI), -1.03 to -0.30; < 0.0004], ecchymosis (SMD, -0.93; 95% CI, -1.13 to -0.73; < 0.00001), and pain (SMD, -1.48; 95% CI, -2.07 to -0.88; < 0.00001) compared with standard osteotomy. Odds of mucosal injury were significantly lower following piezoelectric osteotomy (odds ratio, 0.06; 95% CI, 0.01 to 0.52; = 0.01). There was no difference in duration of osteotomy (SMD, 3.15; 95% CI, -1.82 to 8.12; = 0.22) or total procedure duration (SMD, 0.46; 95% CI, -0.43 to 1.36; = 0.31). One study reported PROs, favoring piezoelectric osteotomy.
Conclusion: This systematic review and meta-analysis provides support (albeit weak, due to low-quality evidence) for piezoelectric over conventional osteotomy, for reducing morbidity in the early postoperative period. High-quality level I data reporting PROs will optimize shared decision-making/informed consent.

Careggi University Hospital, Florence, Italy.
Background: Preservation rhinoplasty, particularly dorsal preservation, has gained prominence with the advent of piezoelectric instruments, which minimize trauma and enhance precision in bone reshaping. This approach presents unique challenges, especially in closed techniques, where spatial limitations complicate the use of piezotomes.
Objectives: To evaluate outcomes of piezo-assisted preservation rhinoplasty using specialized instrumentation to enhance visibility, precision, and postoperative recovery in closed rhinoplasty procedures.

Article Synopsis
- Osteotomy procedures can use either conventional rotary instruments or piezoelectric surgery, each with its own set of benefits and drawbacks related to precision and patient recovery.
- A systematic review of literature compared outcomes between these two techniques, analyzing factors like postoperative pain, swelling, and surgical time.
- The review found no significant difference in swelling, but piezoelectric surgery led to less postoperative pain and better tissue integration, albeit at the cost of longer surgical times.
Safety and accuracy assessment of static computer assisted localized piezoelectric alveolar decortication: an in vitro study.

Article Synopsis
- The study analyzed the safety and accuracy of static computer-assisted corticotomy surgery (sCACS) versus freehand piezocision through a randomized in vitro approach with 260 corticotomies on 20 models.
- sCACS showed significantly less risk of damaging root surfaces (2.21 times less likely) and performed better in accuracy across multiple measurements compared to freehand techniques, indicating less deviation from digital planning.
- The findings suggest that sCACS is a safer and more precise option for performing corticotomies, emphasizing the importance of using surgical guides in tight spaces to minimize root damage in clinical scenarios.

Background: Piezoelectric osteotomy represents a potentially viable alternative to conventional techniques for preparing pilot holes for bone screws. However, piezoelectric osteotomes have demonstrated the potential to heat bone beyond 47 °C, which induces necrosis that could contribute to screw loosening, resulting in osteosynthetic material failure and pseudarthrosis. Thus, we sought to determine the working movements of a piezoelectric drill that resulted in the lowest maximum bone temperatures while ensuring that this optimal drilling motion resulted in temperatures below 47 °C.
