Devastating complication of negative pressure wound therapy after deep inferior epigastric perforator free flap surgery: A case report.

Background: Thermal injuries on free transferred or replanted tissues resulting from loss of sensibility are an infrequent occurrence. They require immediate and appropriate management before they progress to an irreversible condition. Although negative pressure wound therapy (NPWT) can prevent wound progression by increasing microcirculation, the inappropriate application of NPWT on complication-threatened transferred and replanted tissues can induce an adverse effect.

An Anatomical Study of the Palmaris Brevis, Transverse Carpal Ligament, and the Recurrent Motor Branch of the Median Nerve.

The anatomical structures in relation to the carpal tunnel release are the palmaris brevis muscle (PBM), transverse carpal ligament (TCL), and the recurrent motor branch of the median nerve (RMBMN). Our aim is to describe the gross morphology in the Korean population of the PBM, TCL, and RMBMN specifically looking for anomalies, and to determine the muscles encountered during a standard carpal tunnel release. A total of 30 cadaveric hands were dissected.

Temporal augmentation with calvarial onlay graft during pterional craniotomy for prevention of temporal hollowing.

Background: Atrophy of muscle and fat often contributes to temporal hollowing after pterional craniotomy. However, the main cause is from the bony defect. Several methods to prevent temporal hollowing have been introduced, all with specific limitations.

Myxoid Solitary Fibrous Tumor on the Scalp.

Myxoid solitary fibrous tumor (SFT) is very rare soft tissue neoplasm. It is microscopically composed of spindle cells which is individually separated by delicate band of collagen fibers. And this tumor cells are immunohisto-chemistrically highlighted by CD34.

Acute Osteomyelitis in the Hand Due to Dog Bite Injury: A Report of 3 Cases.

As many people keep small dogs as pets, dog bites are common injuries, accounting for approximately 80%-90% of all animal bite injuries. These injuries usually occur on the upper extremities, most commonly on the fingers. Most of these injuries appear as simple lacerations or abrasions of the skin.

Effectiveness of Temporal Augmentation Using a Calvarial Onlay Graft during Pterional Craniotomy.

Temporal hollowing occurs to varying degrees after pterional craniotomy. The most common cause of temporal hollowing is a bony defect of the pterional and temporal regions due to the resection of the sphenoid ridge and temporal squama for adequate exposure without overhang. The augmentation of such bony defects is important in preventing craniofacial deformities and postoperative hollowness.

Transfacial Surgical Approaches to Secure Wide Exposure of the Skull Base.

Background: Treatment of skull base tumors is challenging due to limited access and presence of important neurovascular structures nearby. The success of a complete tumor resection depends on the extent of tumor exposure and secure field of view. While these tumors are often removed by transcranial endoscopic access, transfacial approach is sometimes required depending on the location and size of the tumor.

A rabbit model of fat graft recipient site preconditioning using external negative pressure.

Background: Fat is widely used in soft tissue augmentation. Nevertheless, it has an unpredictably high resorption rate. Clinically, external expansion with negative pressure is used to increase fat graft survival.

Preoperative identification of a perforator using computed tomography angiography and metal clip marking in perforator flap reconstruction.

In perforator flap reconstruction, vascular mapping using preoperative computed tomography (CT) angiography is widely used to confirm the existence and location of an appropriate perforator. This study proposes a rapid, accurate, and convenient method for marking the perforator location on the skin surface. For 12 patients who underwent perforator flap reconstruction between November 2011 and November 2013, metal clips were fixed on the skin surface at the anticipated perforator locations, which were decided using a handheld Doppler.

Importance of Accurate Diagnosis in Pyoderma Gangrenosum.

Pyoderma gangrenosum is a rare inflammatory reactive dermatosis marked by painful cutaneous ulcers. Diagnosis of pyoderma gangrenosum is usually made based on past medical history and after the exclusion of other possible diseases based on the clinical manifestations of the lesion. Diseases that show rapid progression to necrosis and that should not be misdiagnosed as pyoderma gangrenosum include malignant neoplasms and necrotizing fasciitis.

The effect of platelet-rich plasma on survival of the composite graft and the proper time of injection in a rabbit ear composite graft model.

Background: Administration of growth factors has been associated with increased viability of composite grafts greater than 1-cm in diameter. Platelet-rich plasma (PRP) contains many of the growth factors studied. In this study, we evaluate the effect of PRP injection on composite graft viability and the proper time for injection.

Regional analysis of soft tissue thickness on korean buttocks and application to fasciocutaneous flap design.

Background: Various shapes and designs of the gluteal artery perforator flap have been used for treating sacral pressure sores and reconstructing breasts. To establish the ideal fasciocutaneous flap design for use in the gluteal area, the soft tissue thickness distribution was measured.

Methods: Twenty-one buttocks of adult Korean cadavers were analyzed through rectangular subfascial dissection.

Personal Factors that Affect the Satisfaction of Female Patients Undergoing Esthetic Suture after Typical Thyroidectomy.

Background: In esthetic surgery, understanding the factors that influence patient satisfaction is important for successful practice. We hypothesize that the factors that influence patient satisfaction include not only aesthetic and functional outcomes, but also personal factors such as the level of familiarity with factors affecting wound healing and expectations regarding aesthetic outcome.

Methods: One hundred patients who underwent esthetic closure after thyroidectomy were included in this study.

The effect of platelet-rich plasma on flap survival in random extension of an axial pattern flap in rabbits.

Background: Autologous platelet-rich plasma contains multiple growth factors. The aim of this randomized trial was to study the effect of an injection of platelet-rich plasma during random extension of an axial pattern flap procedure.

Methods: Sixteen male New Zealand white rabbits were assigned randomly to two groups of eight animals each.

A new method for creating a definite philtrum by the flipping of an orbicularis oris muscle flap in a patient with an indistinct philtrum.

The philtrum plays a key role in the appearance of the upper lip and nostril sill. Therefore, construction of the philtrum is crucial for attaining a natural appearance of the upper lip. We used a flipping myoplasty of the orbicularis oris muscle on a patient with a flat philtrum in order to effectively reconstruct the philtral dimple and column.

The usefulness of nasal packing with vaseline gauze and airway silicone splint after closed reduction of nasal bone fracture.

Background: Packing after closed reduction of a nasal bone fracture causes inconvenient nasal obstruction in patients. We packed the superior meatus with Vaseline gauze to support the nasal bone, and packed the middle nasal meatus with a Doyle Combo Splint consisting of an airway tube, a silastic sheet, and an expandable sponge to reduce the inconvenience. In addition, we aimed to objectively identify whether this method not only enables nasal respiration but also sufficiently supports the reduced nasal bone.

Effects of a Topical Angiotensin-Converting Enzyme Inhibitor and a Selective COX-2 Inhibitor on the Prevention of Hypertrophic Scarring in the Skin of a Rabbit Ear.

Unlabelled:  Angiotensin-converting enzyme (ACE) inhibitors have been reported to inhibit fibrogenesis, and cyclooxygenase-2 (COX-2) inhibitors, to reduce scarring by reducing the initial inflammation. The authors reasoned that the topical application of these 2 agents may have a complementary effect on scar reduction.

Methods: Captopril (ACE inhibitor), celecoxib (COX-2 inhibitor), or a combination of captopril and celecoxib were topically applied to a skin wound in a rabbit ear, and investigated for the effects on scar formation.

Chest wall reconstruction with a lateral thoracic artery perforator propeller flap for a radiation ulcer on the anterior chest.

A lateral thoracic artery perforator propeller flap is advantageous because it does not require microvascular anastomosis, only rarely involves donor-site morbidity and provides sufficient blood flow. Moreover, by rotating the flap, remote tissues with less radiation-induced damage can be used at the site of the defect. In this article, we report the use of a lateral thoracic artery perforator propeller flap to treat a radiation ulcer.

A new approach to the treatment of nasal bone fracture: radiologic classification of nasal bone fractures and its clinical application.

Purpose: A radiologic examination is required in the treatment of nasal bone fracture to determine the fracture condition. Thus, there is an increasing need for radiologic classification of nasal bone fractures that can be applied to clinical practice.

Materials And Methods: Computed tomography was performed in 125 patients with nasal bone fractures to determine which axial view best showed the entire nasal view.

A new approach to the treatment of nasal bone fracture: the clinical usefulness of closed reduction using a C-arm.

Closed reduction is commonly conducted for the treatment of a nasal bone fracture unless a concurrent fracture or a severe nasal septum fracture is observed. As the reduction, however, is not conducted through the direct gross observation of the fracture site, it is difficult to obtain a good result from it. Accordingly, a supplementary process is required.
