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

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

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

BACKGROUNDS: Cross-face nerve grafting (CFNG) is an important treatment for patients with facial palsy. Currently, two-stage CFNG is frequently performed. CFNG is performed first, followed by coaptation when innervation reaches the grafted nerve ending. The present study compared single-stage CFNG with conventional two-stage CFNG. METHODS: We retrospectively reviewed data of 17 patients who underwent CFNG with zygomatic and buccal branch with hypoglossal crossover. Patients with single-stage (gr

BACKGROUND: Several cases of lipoma in unusual locations in the thorax have been reported. Appropriate surgical treatment depending on the location and shape is often required. CASE PRESENTATION: We herein report an extremely rare case of a chest wall lipoma growing into the pleural cavity. The tumor was successfully removed without damaging the capsule by a combination of direct and thoracoscopic approaches. CONCLUSIONS: Chest wall lipomas growing into pleural cavity can be successfully treated

BACKGROUND: The veno-accompanying artery adipofascial (VAF) flap is nourished by accompanying vessels near large superficial veins. We examined whether the VAF flap can be applied to the external jugular vein. METHODS: Based on anatomic and angiographic studies, we performed reconstructive surgeries using external jugular veno-accompanying artery adipofascial (EJ-VAF) flaps. A retrospective chart review was performed for all patients who underwent this surgery. RESULTS: The presence of arteries

OBJECTIVE: Patients with secondary RP show a wide range of symptoms depending on the condition of vascular structures. If the symptoms are localized to specific fingers and angiography reveals a discrete segment of occlusion of a proper digital artery, we perform proper digital artery reconstruction with an interposition vein graft. The objective of this study was to evaluate the results of the surgery in patients with chronic hand ischaemia. METHODS: A retrospective chart review was performed o

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

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.
