Extramammary Paget's disease (EMPD) is a rare, slow-growing intraepithelial malignancy that mainly involves the genital region, including the vulva, penis, scrotum, perianal, and periurethral areas. Although several treatment options exist, wide local excision with a safe margin is considered the treatment of choice. After resection of the lesion, it is often challenging to reconstruct the defe...

Background: Lip carcinoma is a common cancer with a good prognosis and when patients refer early in the course of disease the results of treatment are acceptable. Surgical procedures for reconstruction of lip defects are the use of remaining lip tissue, tissue from the opposite lip, adjacent cheek tissue, distant flaps and microvascular free flaps. The bitemporal (visor) flap is a regional...

Introduction: Advanced lip carcinomas can invade adjacent structures. Performing surgery for these cancers will lead to defects in this anatomically and functionally important area and will cause post-op difficulties such as drooling, speech alterations and aesthetic considerations, if not properly managed. Case Report: In this study, we will introduce a radial forearm free flap with palmari...

BACKGROUND Post-burn contractures are a commonly encountered problem and many techniques have been described in their treatment. Z-plasties are the commonest local flap procedure done for linear bands with adjacent healthy tissue. Our aim was to assess the use of square flap technique in axillary contractures. METHODS Ten patients with type I and II axillary contractures underwent release by...

Sometimes, because of lack of proper coverage of distal fractured legs, these fractures cause loss of the skin and expose the distal Tibial bones on the medial sides. In such situations, there are two ways for the soft tissue reconstruction: 1. Cross leg flaps and 2. using free flap with microvascular anastomosis. In the present article a case of free Gracilis flap transfer for reconstruction o...

The pedicled anterolateral thigh (ALT) flap based on septocutanous or musculocutanous perforators of the lateral circumflex femoral system is a reliable flap. The use of ALT flap as a pedicled flap is relatively unpopular if compared with its use as a free flap. The flap can be raised as a fasciocutaneous or muscle flap or myocutaneous flap. The pedicled flap has got a lengthy pedicle with a li...

BACKGROUND Immediate autologous breast reconstruction after skin-sparing mastectomy is an esthetically superior method, and a free abdominal flap is often used. However, in Asian patients, little redundant abdominal skin and thin subcutaneous tissue are common, necessitating the development of a more suitable flap design and setting. We devised a narrow flap, the sombrero-shaped flap (S-flap), ...

A novel flap double twist technique was applied to reduce the incidence of post-laser-assisted in situ keratomileusis (LASIK) flap striae. The flap is floated and stroked in the same way as is done for management of first postoperative day striae, where the method is to float and irrigate the flap into position, followed by applying gentle pressure on the flap with a wet Merocel microsponge and...

BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...
