A simple concept for covering pressure sores: wound edge-based propeller perforator flap.

We present a new surgical modification to allow propeller perforator flaps to cover pressure sores at various locations. We used a propeller perforator flap concept based on the detection of newly formed perforator vessels located 1 cm from the wound margin and stimulated by the chronic inflammation process. Between January 2009 and January 2017, 33 wound edge-based propeller perforator flaps were used to cover pressure sores at various locations in 28 patients.

Reconstruction of Extensive Orbital Exenteration Defects Using an Anterolateral Thigh/Vastus Lateralis Chimeric Flap.

Neglected malignant tumors within the orbital region can invade the eyeball, extraocular muscles, and bone substance surrounding the eye. Such patients require orbital exenteration, which may involve extraocular skeletal structures (even exposing paranasal sinuses), resulting in 3-dimensional defects requiring reconstruction. This study presents our experience with anterolateral thigh vastus lateralis (ALT/VL) chimeric free flaps for the reconstruction of extensive orbital exenteration defects involving various paranasal sinuses.

Accordion-style pedicle suspension in inferocentral pedicled mammoplasty.

Objective: In breast reduction surgery, while the primary objective may appear to be decreasing the breast volume, the ultimate goal is to achieve symmetrical, appealing, and sustainable breast cosmesis. To circumvent late-term ptosis following inferior pedicle mammoplasty, methods such as pedicle suspension to the ribs, support with dermal flaps and grafts, and the use of some alloplastic materials have been proposed. This paper presents a method of folding and fixing the inferocentral pedicle on itself and the underlying pectoral fascia.

Rarely seen complication of motor vehicle accidents: Bilateral globe avulsion.

Avulsion of the globe is a rare condition that can occur with severe maxillofacial trauma. A few bilateral cases have been reported. The objective of this study was to present a case of this challenging condition in a 15-year-old male patient who was admitted to the emergency service after a motor vehicle accident.

Multiple Subungual Pyogenic Granulomas Following Levothyroxine Treatment.

Pyogenic granulomas are benign vascular lesions that can result from a large number of etiological factors. Drugs are one etiological factor involved in pyogenic granuloma development. In this study we present our experience of multiple pyogenic granulomas following levothyroxine administration suggesting that levothyroxine hormone replacement therapy might play an important role in the formation of pyogenic granuloma.

Comparison between flexible collagen and vein conduits used for size-discrepant nerve repair: an experimental study in rats.

Primary nerve repair is the gold standard in nerve reconstruction. When primary repair is not possible for injured nerves, conduit-assisted repair methods are frequently used. As conduits, autologous vein segments or allogenic biodegradable products can be used.

Penetrating maxillary sinus injury caused by a construction nail passing through the orbital cavity.

Because of its anatomic position, the orbit is frequently subject to trauma, leading to functional and cosmetic problems. After blunt trauma, orbital fractures can cause functional problems by trapping the periocular tissues without affecting the anatomic integrity of the globe. In comparison, high-energy penetrating injuries can cause serious consequences such as disrupting the lacrimal drainage system and causing loss of vision.

The synergy between endoscopic assistance and extraoral approach in subcondylar fracture repair: a report of 13 cases.

Background: We aimed to present the primary experience of one surgeon with a new surgical technique performed on the first 13 cases and to evaluate outcomes following an extraoral endoscopic approach to subcondylar fractures.

Methods: Fifteen subcondylar fractures in 13 patients, who were treated at Ondokuz Mayis University Hospital between January 2010 and June 2011, were included in this study. Patients were operated on using either endoscopic or open approach.

Simultaneous cheek and lower eyelid reconstruction with combinations of local flaps.

Cheek defects are common facial defects, especially after tumor ablation. Although primary repair yields the best aesthetic outcome, wide defects require flap resurfacing. Among the flap techniques, the cervicofacial rotation/advancement flap is one of the most common.

Comparison of oversized artery and vein grafts for interpositional pedicle lengthening in rat femoral artery.

Vessel grafting is commonly used for revascularization or pedicle lengthening. Although veins are more commonly used, they can form aneurysms when bridging an arterial gap. This can lead to thrombosis, and the risk is increased when there is a size discrepancy.

Versatility of the pinwheel flap to reconstruct circular defects in the temporal and scalp region.

The pinwheel flap technique involves raising four small rotation flaps, which are 90° apart from each other and converge into a defect in their centre. It is suitable for resurfacing defects of the scalp, which offers limited skin mobility. It may also be used for certain circular skin defects on the hairless temporal region.

Auricle reconstruction with a radial forearm flap prelaminated with porous polyethylene (Medpor®) implant.

Severe auricular traumas with extensive involvement of the surrounding structures present with a serious defect necessitating free tissue transfers for reconstruction. In this case report, we present a case of whole left auricle reconstruction with a radial forearm flap prelaminated with porous polyethylene (Medpor®) implant in a 17-year-old female patient. First, a subdermal pouch was fashioned on the volar aspect of the left forearm along the projection of the radial artery and the Medpor implant was placed in this pouch.

Reconstruction of hand injuries with multiple metacarpal defects using free fibular osteoseptocutaneous flap.

Hand injuries with multiple metacarpal involvements often include midpalmar muscle, extensor tendon, and skin defects. Reconstruction method is decided according to the type and amount of structures to be restored. Bone reconstruction and resurfacing of the skin is regarded as priority, and restoration of tendon function and joint mobility can be left for further procedures.

Finger pulp reconstruction with free dorsoulnar artery perforator (DUAP) flap.

Finger pulp is a common site for hand injuries, and pulp reconstruction is significantly important for optimal handling and sensation. Ideal substitute must provide matching texture, tenacity, and slim subcutaneous fat. This article presents six cases in which fingertip and finger pulp reconstruction were performed via free dorsoulnar artery perforator (DUAP) flap.

The Y-V-I principle for salvaging distal digit replantation.

The replantation and revascularization of a distal finger following a crush injury or avulsion are difficult because of the shortness of the vessels after debridement. The success rate of the anastomoses may decrease when they are under tension. To address this, many maneuvers have been described, such as shortening the amputated part or proximal finger stump for tensionless closing, interposing a vein graft between the vessel ends, and vessel transfer from a neighboring finger.

Giant fibrolipoma with osseous metaplasia on the thigh.

Fibrolipomas are characterised by fat lobules embedded in perivascular oval fibrocytes and thick bundles of collagen. Actively growing superficial fibrolipomas rarely display a pedunculated protrusion and, thus, cosmetic and functional problems are uncommon. We present an exceptional case.

Influence of diabetes on critical flaps based on the vascular axis of a sensory nerve.

Delayed sural flap based on the vascular axis of the sural nerve has been advocated for coverage of diabetic foot ulcers. In this study we compared the survival of neurovenous and standard inferior epigastric island flaps in diabetic and non-diabetic rats. VEGF concentrations and electrolyte balance of the flaps were also investigated during elevation and on the fifth day to explore the possible mechanisms that influence ischaemia of the flap during the hyperglycaemic state.

End-to-end microvascular anastomosis in the rat carotid artery using continuous horizontal mattress sutures.

This paper reports a continuous horizontal mattress suture technique with advantages such as decreased time for anastomosis, minimized anastomotic leakage, eversion around the vessel edges, and other advantages which the continuous anastomosis technique has. This technique was compared with the classical interrupted and classical continuous suture techniques on a total of 59 Sprague-Dawley rat common carotid arteries: Group 1 (n = 19), interrupted suture technique; Group 2 (n = 20), standard continuous technique, and Group 3 (n = 20), continuous horizontal mattress technique. Early (30 min) and late (21 days) patency rates, anastomosis time, leakage on clamp release, oozing duration, additional sutures needed, and total number of sutures placed were statistically compared between groups.

Oblique scapular flap.

We report an axial transposition flap based on the anterior branch of the descending branch of the circumflex scapular artery. This has some advantages, including a hidden donor site, easy transfer with no abnormalities, no distortion of the structures, and much pliable tissue.
