Flap thinning is a procedure for making a thick flap thinner. This procedure does more than simply fill in the defected area, and it is better for reconstructing the area both functionally and aesthetically. However, because flap thinning is a rather blind procedure, it may have harmful effects on flap vascularity. Therefore, the vasculature of a flap must be understood before performing flap thinning. This paper analyzes the basic anatomy underlying flap thinning based on the previous anatomic

Current clinical and anatomical studies show that the venous problem associated with the deep inferior epigastric perforator flap results from poor midline-crossing. We examined the venous anatomy of the infraumbilical midline area and the dynamic venous flow of the deep inferior epigastric perforator flap in nine fresh cadavers. All nine abdominal specimens were harvested between the subcostal margin and the groin crease. Two specimens were used to analyze the abdominal venous anatomy, one of w

Despite the aid of tissue expansion, the ideal design of random pattern flap is not always available in patients with extensive skin lesions. We investigated the effectiveness of surgical delay on expanded flaps in pediatric patients. Retrospective cohort study was performed on patients who underwent tissue expansion surgery for extensive skin lesions at Seoul National University Children's Hospital. The surgical delay technique was employed for patients with unfavorable flap conditions related

In lower abdominal flap representing transverse rectus abdominis musculocutaneous (TRAM) flap or deep inferior epigastric perforator (DIEP) flap, superficial inferior epigastric vein (SIEV) exists as superficial and independent venous system from deep system. The superficial venous drainage is dominant despite a dominant deep arterial supply in anterior abdominal wall. As TRAM or DIEP flaps began to be widely used for breast reconstruction, venous congestion issue has been arisen. Many clinical

Single-stage CFNG shows results equivalent to those of two-stage CFNG. Single-stage CFNG is associated with a shorter treatment period and fewer operations.

Our anatomic and angiographic studies in this clinical series indicate that the EJ-VAF flap is a reliable and convenient flap. Thus, it is useful in reconstruction of small to medium head and neck defects.

While the transverse rectus abdominis myocutaneous (TRAM) flap is a popular option for abdominal-based breast reconstruction, abdominal wall morbidities such as bulging or hernia remain a concern. Here, we introduced a surgical technique for reinforcing the abdominal wall using an onlay autograft obtained from discarded zone IV tissue following a primary closure. We compared abdominal wall morbidities between patients receiving an onlay graft and those receiving primary closure only. We retrospe

The trapezius muscle is one of the largest muscles in the body. It is one of the most superficial muscles in the posterior aspect of the neck and thorax. The trapezius flap had been used frequently, but has been used less often in recent years. Still, a trapezius flap can be used in a number of ways in the reconstruction of the upper back or head and neck.

We report a reconstructive case using a free serratus anterior artery perforator flap and an anatomic study. A 50-year-old man with upper esophageal sphincter stricture underwent segmental cervical esophageal resection. The size of the defect was approximately 5.5 cm. We then performed esophageal reconstruction using the free serratus anterior artery perforator flap. Esophagography performed on postoperative day 7 revealed no definite leakage and a viable anastomosis site with wide patency. No c

Digital artery reconstruction using an interposition vein graft is an effective procedure for improving ischaemic pain and ulceration in patients with RP. Smoking and concomitant periarterial sympathectomy were significantly associated with recurrence.
