Impact of magnetorheological fluid composition on their behaviour in gradient pinch mode.

Magnetorheological (MR) fluids can be utilized in one of the fundamental operating modes of which the gradient pinch mode has been the least explored. In this unique mode non-uniform magnetic field distributions are taken advantage of to develop a so-called Venturi-like contraction in MR fluids. By adequately directing magnetic flux the material can be made solidified in the regions near the flow channel wall, thus creating a passage in the middle of the channel for the fluid to pass through.

Hypothermia During Microsurgical Head and Neck Reconstruction and Incidence of Venous Thromboembolism.

Importance: Venous thromboembolism (VTE) is a severe complication after microsurgical free tissue transfer (FTT) to the head and neck. Hypothermia during surgery is a modifiable risk factor, and avoiding it may reduce the postoperative VTE rate.

Objective: To assess the association between hypothermia (temperature <36 °C) and postoperative VTE and free flap pedicle thrombosis rates after head and neck reconstruction with FTT.

Computer-Aided Design and Manufacturing in Free Fibula Reconstruction of the Mandible: Comparison of Long-Term Outcomes with the Conventional Technique.

Background: Pre-operative computer-aided design and manufacturing (CAD/CAM) revolutionized head and neck reconstruction after extirpative surgery. However, studies performing head-to-head comparison to the conventional technique have limited long-term follow-up. We aimed to compare short and long-term outcomes between conventional and CAD/CAM approaches for mandibular reconstruction with free fibula flaps.

Impact of post-operative transoral robotic surgery hemorrhage on adjuvant treatment delays in patients with oropharyngeal squamous cell carcinoma.

Objectives: Transoral robotic surgery (TORS) for the treatment for oropharyngeal squamous cell carcinoma (SCC) carries a risk of post-operative hemorrhage. Increased time from surgery to completion of adjuvant therapy has been associated with decreased survival. Our objective was to assess for adjuvant treatments delays in patients with post-operative bleeding.

Association of Patient and Tumor Characteristics With Outcomes in Young Head and Neck Squamous Cell Carcinoma Patients.

Introduction: We retrospectively studied young patients with head and neck squamous cell carcinoma (HNSCC) to identify factors associated with disease-specific survival (DSS).

Methods: Patient and tumor characteristics of patients aged ≤45 who received treatments for non-metastatic HNSCC were collected to identify factors associated with DSS. Proportional hazards regression was applied separately for surgical and non-surgical patients.
