Purpose: The perforator flaps have established their role in the reconstruction of various soft tissue defects. For the last five years, we have extensively used anterolateral thigh (ALT) flap for the reconstruction of the complex tissue defects of the hand and upper extremity and report the clinical results and our experiences with the versatile applications of this flap. Materials and Methods: From March 2003 through May 2008, 119 free ALT perforator flaps were transferred for reconstruction of the complex tissue defects of the elbow, forearm, wrist and hand after crushing or degloving injuries as well as severe scar contractures. There were 95 females and 24 males. The mean age of the patients was 37 years and mean size of the flap was 170 $cm^2$. In 20 cases, the flap was vascularized by septocutaneous and in 99 cases by musculocutaneous perforators. Intra-muscular dissection length averaged 3.4 cm. The total length of pedicle averaged 8.4 cm and the average arterial diameter was 0.84 mm. End-to-end arterial anastomosis was performed in 103 cases and end-to-side in 16 cases. Results: Flap survival rate was 98.3%(117/119) and there were 6 cases of partial necrosis. Donor site was closed primarily in 41 cases and skin grafts were applied in 78 cases. Conclusion: The reliability and versatility of ALT flap makes it one of the foremost choices for the reconstruction of complex tissue defects of the upper extremity.

Anatomies of the vascular and lymphatic systems have been vital research topics in reconstructive surgery. Harvey was a pioneer who provided the earliest descriptions of the cutaneous vasculature in the 17th century. The concept of vascular territories of the skin was first described by Manchot. The radiographic injection method in cadavers was developed by Salman, who defined more than 80 vascular territories. The arterial system has been thoroughly investigated with the development of regional and free flaps. The concept of axial and random pattern flaps was introduced by McGregor and Morgan. Manchot's vascular territories were refined by Taylor and Palmer as the angiosome concept. Detailed information about the venous circulation is essential for reconstructive surgeries. The concept of intrinsic and extrinsic venocutaneous vascular systems was introduced by Nakajima and led to the development of the venoadipofascial flap. The importance of venous augmentation in flap survival was emphasized by Chang. The lymphatic system was discovered much later than the arterial and venous systems. Aselli was credited for discovering the lacteal vessels in the 17th century; mercury was popularly used as a contrast agent to distinguish lymphatic vessels for the next three centuries. A radiographic method in cadavers was developed by Suami. Lymphatic imaging devices are constantly upgrading, and photoacoustic imaging was recently introduced for three-dimensional visualization of architecture of superficial layers of the lymphatic and venous systems.

We aim to provide our surgical techniques, and outcomes of functional scrotal reduction procedures with complete preservation of the genitourinary original anatomy in a simple way without using complicated skin grafting or skin advancement flaps in Patients with huge and long-standing scrotal lymphedema 18 patients ages ranged from 14-65 with a median of 30 years. Functional scrotal and penoscrotal reduction was attained in all cases, without distortion of the genitourinary anatomy and without the need for advancement, rotational or free flaps, maximal scrotal diameter was reduced from median of 61[48-92] cms to a median of 25[21-29] cms (P<0.0001) and remained almost unchanged at the end of the follow up period 26[22-34] cms (P<0.0001). Sexual performance and voiding capacity were improved in all patients, testicular vascularity was unaffected and the Glasgow Benefit Inventory (GBI) for the quality of life showed marked enhancement in the total 55.5[50-72], general 55.5[50-72], social 100[50-100] and physical 16.6[16-33] points subscales. According to our experience, surgery remains the gold standard treatment for management of huge scrotal lymphedema, successful preservation of the genitourinary functions can be attained despite the size in most cases with excellent cosmoses.

Purpose: Defects involving the ankle and foot are often the result of road traffic accidents. Many such defects are composite and require a flap for coverage, which is a significant challenge for reconstructive surgeons. Various locoregional options, such as reverse sural artery, reverse peroneal artery, peroneus brevis muscle, perforator-based, and fasciocutaneous flaps, have been used, but each flap type has limitations. In this study, we used the distally based lateral supramalleolar flap to reconstruct distal dorsal defects of the foot. The aim of this study was to analyze the efficacy of the flap in reconstructing distal dorsal defects of the foot. The specific objectives were to study the adequacy, reach, and utility of the lateral supramalleolar flap for distal defects of the dorsum of the foot; to observe various complications encountered with the flap; and to study the functional outcomes of reconstruction. Methods: The distal dorsal foot defects of 10 patients were reconstructed with distal lateral supramalleolar flaps over a period of 6 months at a tertiary care center, and the results were analyzed. Results: We were able to effectively cover distal foot defects in all 10 cases. Flap congestion was observed in two cases, and minor graft loss was seen in two cases. Conclusions: The distally based lateral supramalleolar flap is a good pedicled locoregional flap for the coverage of distal dorsal foot and ankle defects of moderate size, with relatively few complications and little morbidity. It can be used as a lifeboat or even substitute for a free flap.

Although regional and myocutaneous flaps are still the standard in head and neck reconstruction. The capacity to transfer distant tissues by microsurgical technique expands the reconstructive surgeon's ability to restore severe deformities of the head and neck. From 1981 to 1985, thirteen patients with extensive defects of the head and neck after extirpative surgery of tumor have been reconstructed utilizing the technique of microsurgical composite tissue transplantation. In this series of patients, six presented with reconstructions in the different region of the head and neck with review of literatures. The results of case analysis are summarized as follows: 1) Transplantation was successful in twelve among thirteen patients (92%). 2) Seven patients presented with malignancy and six with benign tumor. 3) Frequent sites of reconstruction were face and mandible. 4) Fourteen free composite tissue transplantations for reconstruction of thirteen patients were obtained six different tissue compositions from eight different donor sites. 5) The recipient artery and vein was most often superficial temporal or facial vessels. 6) The average time of operation was ten hours.

Reconstruction of oral soft-tissue defects following resection of oral carcinomas can be achieved using various techniques including microsurgical tissue transfer. However, there seems to be a role for regional or local flaps. Small to medium-size defects can be functionally reconstructed with the platysma myocutaneous flap as an excellent choice particularly in medically compromised patients not being eligible for free tissue transfer. The present paper reviews the indication, surgical technique, and complications following reconstruction of defects of the oral cavity with the platysma myocutaneous flap.

Various flaps are using for reconstruction of esophageal defect. The choice of reconstruction is depended to the oncologic needs of the situation. If the entire esophagus or significant part of the thoracic esophagus is involved by tumor, then total esophagectomy and gastric pull-up or colon transposition is indicated. But for most hypopharyngeal tumors, laryngopharyngeal tumors, and cervical esophageal tumors, segmental resection of these area and replacement with a jejunal fee or forearm free flap has become the standard technique. The authors have experienced a case of total pharyngo-laryngo-esophago-gastrectomy and colon transposition in a patient of esophageal cancer following partial esophagectomy and gastic pull-up due to corrosive esophageal stricture. We report this case with brief review of the literatures.
