Objective: The goal of this study was to compare conventional osteotomes and Magic Saws in terms of edema and ecchymosis, in rhinoplasty patients.
Study Design: A retrospective, case-control study.
Methods: In this prospective, randomized study, we evaluated the results of 258 rhinoplasty patients who underwent osteotomy by either conventional osteotomes or new designed saws called; "Magic Saws." On postoperative days 2 and 7, the patients were photographed by the surgeon; photographs were evaluated by another otolaryngologist, blinded from the osteotomy procedure.
Results: There were no statistically differences between the groups, in terms of age, sex, weight, or average arterial blood pressure (P > 0.05). The postoperative periorbital edema (days 2 and 7) and ecchymosis (day 2) scores were significantly higher in the conventional osteotomy group, as compared to Magic Saw group (P < 0.05). However, on postoperative day 7, the differences in the periorbital ecchymosis scores between the groups, were not statistically significant (P > 0.05).
Conclusions: As compared to conventional osteotomes, Magic Saws were reported to be associated with minimal soft tissue injury, as well as decreased edema and ecchymosis, in the early postoperative period after rhinoplasty.

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.

The CARLO (cold ablation robot-guided laser osteotome) is a compact device with integrated multiple sensory, steering and safety checking elements. A multi-center study was performed to evaluate the CARLO device for the linear part of midface osteotomy in 28 patients. Feasibility, success rate, safety, performance and experience of the surgeons were assessed and evaluated.

Background: Severe elbow deformities are common in developing countries because of neglect or as a result of prior treatment that achieved poor reduction. Various osteotomy techniques have been defined for the surgical correction of elbow deformities. However, severe elbow deformities (>30°) pose a substantial challenge for surgeons because limited surgical options with high complication rates have been described in the literature.

Background: With the increased utilization of reverse total shoulder arthroplasty (RTSA), there has been a corresponding increase in the incidence of and demand for revision RTSA. In cases in which the patient has undergone multiple previous surgeries and presents with well-fixed shoulder implants, even the most experienced shoulder surgeon can be overwhelmed and frustrated. Having a simple and reproducible treatment algorithm to plan and execute a successful revision surgery will ease the anxiety of a revision operation and avoid future additional revisions.
