Tie-over bolster fixation is the most common method of securing a skin graft. The bolster material can consist of various materials, including sterilized polyurethane foam. Mepilex Ag is a silver-containing polyurethane-foam wound-dressing material that has a broad-spectrum antibiotic effect.

Keloid scars tend to occur in high-tension sites due to mechanical stimuli that are involved in their development. To date, a detailed analysis of keloid distribution focused specifically on facial and neck areas has not been reported, and limited literature exists as to the related mechanical factors. To rectify this deficiency of knowledge, we first quantified the facial and neck keloid distribution observed clinically in 113 patients.

The essence of treating scar contractures lies in covering the skin deficit after releasing the contractures, typically using flaps or skin grafts. However, the specific characteristics of scar contractures, such as their location, shape, and size, vary among patients, which makes surgical planning challenging. To achieve excellent outcomes in the treatment of scar contractures, we have developed a dimensional classification system for these contractures.

Sternal osteomyelitis is a rare but devastating complication of median sternotomy. To achieve good outcomes, it should be diagnosed early and treated appropriately. Standard treatment involves antibiotics, debridement, and reconstruction with flaps.

Background: Key risk factors for hypertrophic scarring and surgical-site infections are high-tension wounds, fat necrosis, and dead space. All could be prevented by appropriate superficial fascia suturing. However, the as-yet poorly researched anatomy of the superficial fascia should be delineated.

Background: Soft-tissue defects in the hand and digits can be effectively covered by using the free superficial palmar branch of the radial artery (SPBRA) flap, which is harvested from the radial volar wrist. Because previous anatomical studies on this flap are limited, multidetector-row computed tomographic angiography of the upper limbs was conducted to characterize the three-dimensional anatomical structure of the SPBRA and its perforators in living patients.

Methods: This retrospective anatomical study was conducted from 2014 to 2019.

Keloids are laterally growing fibroproliferative skin disorders. Severe keloids spread widely, sometimes over joints, thus significantly limiting motor function. They are associated with recurrent, very painful draining infections.
