Optimizing Injection Molding Tool Design with Additive Manufacturing: A Focus on Thermal Performance and Process Efficiency.

Injection molding plays a pivotal role in modern manufacturing, enabling the mass production of complex components with high precision. However, traditional tooling methods often face challenges related to thermal management, design constraints, and material efficiency. This study examines the use of additive manufacturing (AM) in the development and optimization of injection molding tools to overcome these limitations.

Practice Patterns in Sternal Closure and Evaluation of Adoption of a Novel Sternal Closure Device.

Objective: The technique for sternal closure has remained largely unchanged owing to the efficacy, simplicity, and low cost of stainless-steel sternal wires. Despite their ubiquity, several other closure devices designed to address the complications associated with sternal wires such as sternal bleeding and dehiscence have become popular. We have developed a novel sternal closure device that reduces sternal bleeding and dehiscence.

Mechanical Analysis of a Novel Sternal Closure System in Static Tensile Loading.

The most common means of sternal closure after sternotomy is stainless steel wire cerclage. These wires, while inexpensive and simple in design, are known to be associated with low strength and sternal dehiscence. In this biomechanical analysis, we compare single sternal wires, double sternal wires, and a novel sternal closure device we have designed to mitigate sternal dehiscence.

Deep Neck Lift: Defining Anatomical Problems and Choosing Appropriate Treatment Strategies.

A well-contoured neck is an artistic imperative to an attractive and appealing appearance. A good neckline conveys a sense of youth, health, fitness, confidence, and vitality and lends an appearance of decisiveness, sensuality, and beauty. Neck improvement is of high priority to almost every patient seeking facial improvement, and the results of "face lift" procedures are judged largely by the outcome obtained in the neck.

High SMAS Facelift: Combined Single Flap Lifting of the Midface, Cheek, and Jawline.

The traditional deep plane and "low" cheek superficial musculoaponeurotic system (SMAS) flaps elevated below the zygomatic arch suffer the drawback that they cannot, by design, exert an effect on tissues of the midface and infra-orbital region. Traditional deep plane and low designs target the lower cheek and jowl only and produce no improvement in the upper anterior cheek and "midface" area. Planning the flap "higher," along the zygomatic arch, and extending the dissection medially in an "extended SMAS" fashion to release and mobilize midface tissue, overcomes this problem and allows a combined, simultaneous, single flap lifting of the jawline, cheek, and midface.
