In most cases, patients with Bowen disease lesions can be easily treated by surgical excision and direct closure; however, the ultrasonic surgical aspirator, an instrument in common use in many fields, offers a good treatment alternative with few drawbacks for patients with lesions that are large and/or located in joint areas, areas that are hard to heal,(More)
Despite recent advances in reconstructive surgery, extremely wide and thin flap coverage has rarely been reported. Recently, the authors developed a technique for transferring a very wide and thin flap from the thigh area using microdissection. In this procedure, both perforators of the anterolateral thigh flap and the tensor fasciae latae perforator flap(More)
Negative pressure wound therapy (NPWT) is a useful wound dressing that can be applied to a wide variety of wounds. Patients with ischaemic wounds, however, may experience further necrosis with NPWT at the commonly recommended pressure of -125 mm Hg. We hypothesized that with a suction pressure of -125 mm Hg, tissue pressure will likely occlude most of the(More)
Myositis ossificans traumatica (MOT) is a disease in which muscular ossification develops following trauma. Almost all cases of MOT are found in skeletal muscle. The authors report in a 39-year-old man MOT involving several muscles in the head and neck, namely, bilateral masseter muscles, the left temporal muscle, the left lateral pterygoid muscle, and the(More)
One of the most frequently requested facial contour improvement procedures in the Orient is reduction malarplasty. However, until recently, osteotomies in the malar region have been performed by means of a coronal incision that required a larger incision and more invasive procedure than many patients are comfortable with when considering an elective(More)
A microdissected thin groin flap is a uniform thin flap with a long vascular pedicle prepared by microdissection of the deep branch of the superficial circumflex femoral system (SCIS). However, the safe dimensions of the flap are not known, and anatomical variations of the SCIS sometimes impede elevation of the flap based on the deep branch. Therefore,(More)
BACKGROUND For a refined microsurgical reconstruction, it is desirable to adjust the flap to fit the three-dimensional details of the defect. Essentially, each vessel arborized in the subcutaneous adipose tissue supplies axial blood flow to an individual small area surrounding the vessel. Therefore, free alteration of the flap would be possible if the(More)
The Biomechanics of pharyngeal swallowing was investigated by videofluorography in 10 healthy subjects (9 men and 1 woman) during swallowing of 3 ml of fluid contrast medium and a small spoonful of jelly contrast medium. The items measured were the sequential movement of the hyoid bone: hyoid bone angle; epiglottis angle: antero-posterior diameters of the(More)
We used an ultrasonic surgical aspirator on the epidermal surface to perform dermabrasion instead of the conventional motor-driven grinder. It was determined on histologic examination that it is possible to fragment the epidermis with greater selectively using the ultrasonic surgical aspirator. Abrasion also can be performed safely on spotty lesions and(More)
