Dynamic Eye Closure Restoration in Facial Palsy with Neurotized Platysma Muscle Graft in Rats.

Background:  One of the most devastating deficits of facial paralysis is eyelid dysfunction, which is controlled by the orbicularis oculi muscle (OOM), as it leads to loss of the protective mechanism of the eye. This study used a rat model to assess the functional outcomes of neurotized platysma muscle grafts (PMGs) for OOM replacement.

Methods:  Forty male Sprague-Dawley rats with iatrogenic right eyelid dysfunction were divided into five groups: one control group and four groups utilizing PMG with different sources of nerve innervation.

Chimerization of Monitor Flap in a Vascularized Ulnar Nerve Flap Is an Efficient Way for Vascularity Monitoring and the Reinnervation Checkup after Its Transplantation.

 Free vascularized ulnar nerve flaps (VUNF) are effective method for long nerve defects reconstruction. However, the monitorization of its microvascular circulation and the nerve regrowth can be challenging since it is usually designed as a buried flap. We designed a skin paddle based on a septocutaneous perforator from the ulnar artery that can be dissected and raised in conjunction with the vascularized ulnar nerve flap, which aims to improve postoperative monitorization to optimizing the clinical results.

International Microsurgery Club Webinar Series-Bridging the Knowledge Gap during the COVID-19 Pandemic.

Background:  The impact of the coronavirus disease 2019 (COVID-19) outbreak shut down most conferences. To minimalize the influence, virtual meetings sprang up subsequently. International Microsurgery Club (IMC), as one of the largest professionals-only online microsurgery education groups worldwide, began to host regular weekend webinars during the pandemic to fill the knowledge gap.

Small-volume detection: platform developments for clinically-relevant applications.

Biochemical analysis of human body fluids is a frequent and fruitful strategy for disease diagnosis. Point-of-care (POC) diagnostics offers the tantalizing possibility of providing rapid diagnostic results in non-laboratory settings. Successful diagnostic testing using body fluids has been reported on in the literature; however, small-volume detection devices, which offer remarkable advantages such as portability, inexpensiveness, capacity for mass production, and tiny sample volume requirements have not been thoroughly discussed.

Holistic reconstruction of mandible defect, lower lip and chin sensation, and smile reanimation in an advanced gum cancer patient: A case report.

Facial deformity, facial paralysis, and sensory loss are inevitable after some head and neck tumor resection and reconstruction, especially in high stage cancer. To overcome these obstacles, we present a case of T4a gum cancer patient (41-year-old) who received holistic reconstruction of the mandible defect via an osteo-peroneal-artery-perforator combined flap for defect coverage and cross-mental nerve graft for lower lip and chin sensation at the primary stage, followed by ipsilateral facial nerve (lower trunk) innervated gracilis functioning free muscle transplantation for facial reanimation and correction of the sunken face 3 years later. After 4.

The Preferred Management of a Single-Digit Distal Phalanx Amputation.

Background:  Replantation of a single digit at the distal phalanx level is not routinely performed since it is technically challenging with questionable cost-effectiveness. The purpose of this study was to analyze international microsurgeons' clinical decisions when faced with this common scenario.

Methods:  A survey of a right-middle finger distal phalanx transverse complete amputation case was conducted via online and paper questionnaires.

Impact of Social Media on Current Medical Conferences.

Background:  Medical conferences are forums for research, continuing medical education, and networking. Social media is increasingly used for communication and networking due to its low cost and ability to overcome large distances. This study investigates the impact that social media brings to the current conference system.

Tips for Making a Successful Online Microsurgery Educational Platform: The Experience of International Microsurgery Club.

The presence of online learning resources has grown tremendously in recent years. They provide powerful and yet easily accessible means of learning and sharing knowledge. Online learning resources now encompass all aspects of medicine, and microsurgery is no exception.

Use of Social Media and an Online Survey to Discuss Complex Reconstructive Surgery: A Case of Upper Lip Reconstruction with 402 Responses from International Microsurgeons.

Background: The best reconstructive strategy for upper lip defects is still in debate. The purpose of this study was to analyze the decisions made by international microsurgeons, who were participated through online questionnaire, distributed by email and social media network.

Materials And Methods: A case of a two-thirds upper lip oncologic defect was presented via an online questionnaire and 402 microsurgeons replied their treatment options.
