A Simple and Innovative Technique to Offload the Microsurgical Loupe

The loupe plays a critical role in the microsurgeon's arsenal, helping to provide intricate details. In the absence of adequate subcutaneous fat, the prismatic lens of the spectacle model may exert enormous pressure on the delicate skin of the nasal bone. By developing a soft nasal support, the author has incorporated the principle of offloading into an elegant, simple yet brilliant innovation. A simple procedure such as this could prove invaluable for microsurgeons who suffer from nasal discoloration or pain as a result of prolonged use of prismatic loupes. With this technique, 42% of the pressure applied to the nose is reduced.

Design and Harvest of the Thin Profunda Artery Perforator Flap

Here is a video that shows the harvest of a thin profunda artery perforator flap from the left thigh. In conjunction with preoperative computed tomography angiography, measurement of the morphology of the perforators and their branches, the pedicle length, and the vertical locations of the two branches from the ischial tuberosity are performed. A handheld doppler is used to confirm the location of both branches. As a result of the authors' results, preoperative computed tomography angiography is a valuable way of obtaining detailed anatomical information such as the shape of perforators, their path through the septum or muscle above the deep fascia, as well as the thickness of the skin. It is important to know that computed tomographic angiography is an excellent means of making an assessment of the entire vascular anatomy of the leg, and it results in making an informed decision about the choice of flaps, based on the patient's anatomy and the characteristics of the defect.

A Modified Technique of Mouse Vertical Sleeve Gastrectomy Using Two Disposable Micro-clamps

Vertical sleeve gastrectomy (VSG) is a type of bariatric surgery that is accepted as the simplest but most efficient surgical modality to treat morbid obesity. A mouse model of VSG has been widely utilized to investigate the underlying mechanisms of VSG. There are numerous microsurgical techniques for VSG in mice, and the authors report herein a modified technique with 2 disposable micro-clamps to simplify the surgery. The key aspects of the modification are to use the micro-clamps as non-crushing tissue clamps for anastomosis as well as vascular clamps for hemostasis. Mean body weight at postoperative week 1 was 24.1 grams, which is equivalent to a 16.1% loss of original body weight, and there was no mortality after antrum preservation VSG. This simplified surgical technique will best serve as a tool to investigate either the underlying mechanisms of VSG or the intrinsic change to the stomach after VSG.

An Innovative Method for the Training of Microsurgical Anastomosis Using a Silicone Tube

One of the aims of several reconstructive surgical procedures is to achieve a patent microvascular anastomosis. Developing clinical competency in this specialized skill requires intensive training on live animal models as a first step. The early training stage of microvascular anastomosis can be stressful for novices. This is because the rat vessels used in such training courses are usually too small and fragile for novices to maintain the vascular lumen in an optimal fashion. Throughout this paper, the authors discuss the use of a silicone tube to provide structural support to vessels throughout the entire precarious suturing process. Using this modified version of the conventional microvascular anastomosis technique may facilitate initial skill acquisition in the rat model.

Dangers of a False Sense of Security in a Huge Mastoid Cholesteatoma With Skull Base Erosion and Cerebrospinal Fluid Leakage

The author reports a case involving a 59-year-old man with delayed presentation of a huge mastoid cholesteatoma complicated by skull base erosion and cerebrospinal fluid leakage. Delayed presentation of this disease entity can have negative health consequences for patients. Regular otologic examinations, audiologic follow-up, and imaging examinations are viewed as the most effective strategies for the prevention of this type of situation. Early recognition of cholesteatomas is essential, as appropriate and timely treatment can prevent this rare comorbid condition from becoming fatal.

Head and Neck Juxtacortical Chondrosarcoma

The incidence of Head and Neck Juxtacortical Chondrosarcoma (HNJCS) is extremely rare. Among a large database, the authors could identify only nine cases of HNJCS that have been amply described. It has been observed that irrespective of the location of the body, HNJCS has a consistent clinical and diagnostic profile. HNJCS is generally a low or intermediate grade malignancy with a low rate of recurrence and metastases. Primary surgical excision with negative margins was found to be the therapeutic modality of choice. Radiotherapy and chemotherapy have limited roles in the management of HNJCS.

Chang's Technique of Sequential End-to-Side Microvascular Anastomosis

This novel technique of sequential ETS micro-venous anastomosis is a modified technique from its classical form. The unique use of vessel loops provides protection to the vessel, while it achieves equisegmental IJV occlusion for sequential (proximal to distal) venous anastomosis. This method not only saves precious operating time from repetitive positioning of instruments and recipient vessel (IJV), but also creates a safer operating field for the microsurgeons. Utilizing a second single vascular clamp over the anastomosis junction provides an anchoring point for self-retraction by revealing and maintaining an accessible position to the posterior wall, once it is turned at 180 degrees laterally. This maneuver allows the surgeon to have full control of the surgical field and perform ETS micro-venous anastomosis confidently and independently.

Lateral Plantar Artery as Recipient Vessel for Microsurgical Lateral Plantar Forefoot Reconstruction

Division of the lateral plantar artery does not jeopardize the foot circulation because of anastomosis of the lateral plantar artery with the dorsalis pedis artery at the first intermetatarsal space. However, care should be taken with patients with peripheral artery occlusive disease and the flow of dorsalis pedis artery should be confirmed before surgery. Given the advantages of sizable vessel, easy dissection, and proximity to the defect, we believe that the lateral plantar artery might be a valuable option as recipient vessel for lateral plantar forefoot reconstruction.
