BACKGROUND: Free-flap surgery and skin grafting can be used to reconstruct large facial defects that may result after skin cancer removal by Mohs micrographic surgery (MMS). However, these two methods may produce low postsurgical patient satisfaction with aesthetics, and free-flap surgery may produce an undue burden for the majority of skin cancer patients, who are of advanced age. Hence, the authors examined outcomes of large facial defect reconstruction using multiple flaps. METHODS: Among patients undergoing MMS for skin cancer at Pusan National University Hospital between January 2013 and December 2015, we evaluated 7 patients (2 males, 5 females; average age, 73...

BACKGROUND: Simulation training is becoming an increasingly important component of skills acquisition in surgical specialties, including Plastic Surgery. Non-living simulation models have an established place in Plastic Surgical microsurgery training, and support the principles of replacement, reduction and refinement of animal use. A more sophisticated version of the basic chicken thigh microsurgery model has been developed to include dissection of a type 1-muscle flap and is described and validated here...

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect...

The use of free flaps is considered the "gold standard" for reconstruction of head and neck defects. Locoregional flaps allows a better aesthetic result compared to free flaps, whenever there's an external skin defect. However the use of free flaps is not always adequate in the presence of preoperative comorbidities or previous surgeries. Since the description of the trapezius myocutaneous flap in the 1980's, many authors have published the results of the applicability of this flap in head and neck salvage reconstructive surgery...

BACKGROUND: The distally based peroneus brevis muscle flap has proved to be a simple solution for small- to moderate-sized wounds of the lower limb. The length of the muscle belly suitable for coverage is a crucial parameter. In this study, we evaluated the capability of 3D MRI of the lower limb to measure it preoperatively. METHODS: Between 2008 and 2017, 32 patients with lower limb defects underwent preoperative MRI to measure the peroneus brevis muscle length...

The repair of large tracheal segmental defects remains an unsolved problem. The goal of this study is to apply tissue engineering principles for the fabrication of large segmental trachea replacements. Engineered tracheal replacements composed of autologous cells ("neotracheas") were tested in a New Zealand White rabbit model. Neotracheas were formed in the rabbit neck by wrapping a silicone tube with consecutive layers of skin epithelium, platysma muscle and an engineered cartilage sheet, and allowing the construct to mature for 8-12 weeks...

BACKGROUND: Despite the growing use of medical modeling in other surgical specialties, its utilization in extremity reconstruction has remained limited. METHODS: We present the application of medical modeling for ulna reconstruction using a microvascular fibula free flap. RESULTS: Following a motor vehicle accident, the patient suffered segmental loss of the right radius and ulna with concomitant forearm soft tissue and muscle loss. Using medical modeling, imaging from the unaffected contralateral forearm and lower extremity was used to plan a reconstruction that restored the anatomic length and orientation of the ulna...

PROBLEM: During palatal fenestration procedure the vascularised, respiratory nasal lining is often sacrificed inadvertently. It normally functions to keep the inhaled air warm, humid and dust free. CONCLUSION: This vascularised nasal lining when uninvolved oncologically can easily be preserved. Preservation of the vascularised nasal lining shall decrease the leakage of nasal secretions and aid in the healing of reconstruction of the defect when local or regional flaps are used...

BACKGROUND: Little attention has been given to the segmental free gracilis muscle flap supplied by secondary proximal pedicles. We introduce a technical refinement for small-sized three-dimensional defect reconstruction on the foot. METHODS: Between November 2013 and August 2016, three patients with a mean age of 66 years (range 47-70 years) were included. A segmental gracilis free flap supplied by the most proximal secondary pedicle was harvested according to a modified "nugget design" to treat small-sized defects on the lower extremity requiring dead space reconstruction...

BACKGROUND: Large soft tissue defects of ankle and foot always have been challenging to reconstruct. Reverse sural flaps, free flaps have been used for this problem with variable success. Reverse peroneal artery flap is an option to use with reliability without microvascular repair. Connections of peroneal artery around talus and ankle joint are deep and reliable with anterior tibial and posterior tibial artery. Arterial inflow and venous drainage improved with including short saphenous vein and reverse sural artery in the flap...

BACKGROUND: Reconstruction of upper extremity deformities continues to be a challenge to the reconstructive surgeon. Various loco regional, distant and free flaps are available for reconstruction. However, each has its own set of advantages and disadvantages. Of the commonly performed local flaps, radial artery forearm flap, and the posterior interosseus artery flap stand out prominently. Recently, perforator propeller flaps have been used for resurfacing the upper extremity. The anterior interosseus artery perforator flap is an uncommonly used and described flap...

INTRODUCTION: Free muscle flaps are being used more commonly for complex lower limb reconstruction. Up to 33% of flaps used to reconstruct lower limb trauma will require an orthopaedic procedure after reconstruction. To date there have been only case reports detailing the variable survival of muscle flaps after actual or simulated pedicle injury and the process and timeframe of neovascularisation remains undefined. We aim to show that perfusion of a muscle flap is possible after injury to its anatomical vascular pedicle...

Inhibition of β-Secretase (BACE1) is crucial for the treatment of Alzheimer's disease (AD). Availability of BACE1 crystal structures in both apo and complexed forms enables to find structure-based BACE1 inhibitors for controlling AD. There are two catalytic aspartates (ASP32 and ASP228) presents in the active domain of BACE1. In order to understand the binding mechanism and structure-activity relationship of amidine-containing BACE1 inhibitors, molecular docking, and pharmacophore and 3D-QSAR studies have been carried out with 34 amidine derivatives to develop a pharmacophore model...

Microvascular reconstruction of ablative defects has become a mainstay of contemporary management of head and neck cancer patients. These techniques offer myriad tissue options that vary in character, volume, and components and have vastly improved the esthetic and functional outcomes achieved in this patient population. Although consensus exists regarding the reliability and functional and esthetic benefits of free tissue transfer, the same cannot be said for oncologic outcomes. The increase in resources required for the routine use of free tissue transfer has led to asking this question-Do vascularized free flaps allow for increased surgical margins and improvements in oncologic outcomes?...
