INTRODUCTION: Facial bone defects are frequently encountered problems in clinical practice. Bone grafts, flaps, and alloplastic materials are often used in their treatment. This leads to donor site morbidity and prolongation of the operation. The authors have planned this study to examine whether adipose tissue derived stromal vascular fraction (SVF) has an osteogenic effect in the critical sized membranous bone defect of the zygomatic bone. MATERIALS AND METHODS: Twenty male Wistar Albino rats were used...

INTRODUCTION: Soft tissue defect on lower limb can result in an intractable wound. Surgeons resort in flaps to cover these injuries. Including fascia as in the case of a fasciocutaneous flap increases survey of the flap. Rising a perforator flap avoids to sacrifice a major vessel whence the nourishing perforator artery is born. We wanted to explore suprafascial distribution of the fibular skin perforator arteries supposing possible to find out a vascular axis composed of anastomoses of the fibular perforator vessels...

BACKGROUND: Reconstruction of moderate-sized mucosal defects of the oral cavity or oropharynx represents a surgical challenge. Buccinator myomucosal flaps seem to provide "ideal reconstruction" of oral/oropharyngeal defects because they carry a thin, mobile, well-vascularized, and sensitive tissue, like that excised or lost. Nevertheless, these flaps are not immediately popular because of confusion surrounding the complex terminology used to name them. METHODS: After a retrospective study on our experience and a literature review, the authors propose a new rational and simplified nomenclature for the classification of buccinator myomucosal flaps, which clarifies the source vessel, the composition of the flap, and the type of transfer...

BACKGROUND: Orbital exenteration is a significant reconstructive challenge for plastic surgeons. Options described for these defects range from healing by secondary intention to free tissue transfer. The authors present our preferred reconstruction of orbital defects with free forearm-based flaps, which provides quality soft tissue and orbital contouring in 1 stage to consistently allow placement of bone-anchored implants for eventual orbital prosthesis. METHODS: This conical shape of the orbit is deconstructed into a "Pac-Man" type shaped flap that leaves adequate depth for a prosthesis...

Hypoxia-inducible factor-1α (HIF-1α) plays a key role in angiogenesis, improves flap survival, and activates autophagy. The effect of HIF-1α-induced autophagy is still debatable. Thus, we investigated the effect of HIF-1α-induced autophagy on multiterritory perforator flap survival. In this study, 99 male Sprague-Dawley rats received multiterritory perforator flap procedure and were divided into three groups with 33 each. The dimethyloxalylglycine (DMOG) plus 3-methyladenine (3-MA) group received intraperitoneal injection of DMOG (40 mg/kg) and 3-MA (10 mg/kg)...

Surgical management of extensive tumors in the mandibular region leads to massive disfigurement of the face. Also the prosthetic outcome of such patients rehabilitated with free soft tissue flaps is very poor. Reconstruction of extensive defects to overcome the disfigurement is a challenging procedure and can be achieved with free fibula flap. Free fibula graft provides sufficient length of bone for the reconstruction of the postsurgical defects. Excellent vascularity of fibula flap allows for easy uptake of the graft and osseointegration of the dental implants...

BACKGROUND: The optimum number of microvascular anastomoses for safe free tissue transfer is controversial. Although the case for 2 venous anastomoses versus 1 anastomosis has been argued, the use of an additional arterial anastomosis has not been examined in detail. METHODS: Twelve patients who underwent 2 arterial anastomoses for a free flap transfer were identified retrospectively from the medical records of patients undergoing reconstruction for head and neck cancer...

Late arterial thrombosis of a free flap is rare and usually unsalvageable because it is hard to detect. We herein report 2 cases of arterial thrombosis of a free flap after microvascular head and neck reconstruction due to the combined factors of pedicle artery loop and compression by a swollen submandibular gland, the occurrence of thrombosis in both of which was > 72 hours after the operation. In case 1, the arterial thrombosis was undetectable, and it was too late for a successful take-back operation, so the flap was lost...

Gender reassignment surgery has gained in popularity with increased media exposure and society's recognition of gender dysphoria. Female-to-male gender reassignment often begins with the "top" or chest surgery. Mastectomy with free nipple grafting is the most frequently described technique in the literature. This technique is reliable yet lacks the ability to provide a true male chest shape. We discuss our technique for female-to-male "top" surgery combining traditional mastectomy techniques with a lower pole pedicle vascularized areola and a pectoral implant...

BACKGROUND: Free jejunal transfer has a high success rate, but if vascular thrombosis occurs, the salvage of failing flap with reanastomosis is difficult. This study described a combined deltopectoral (DP) and pectoralis major musculocutaneous (PMMC) flap 2-step technique for cervical esophageal reconstruction after free-jejunal-flap necrosis. METHODS: In step 1, the detection of free jejunal flap with the subsequent debridement of necrotic and infected tissue was followed by the construction of external fistula on the pharyngeal side with the hole in cervical skin and the construction of another external fistula on the esophageal side and tracheal stoma with a single or double DP flap...

After mandibulectomy in cancer surgery, reconstruction is often performed with a reconstruction plate covered with a soft-tissue free flap in patients in poor condition. However, the rate of complications for mandibular reconstruction is higher with a reconstruction plate than with vascularized bone grafts. We have developed a costal cartilage wrapping method to prevent exposure of the mandible reconstruction plate. The eighth costal cartilage was removed and split into 2 pieces to wrap around the reconstruction plate...

The fasciocutaneous lateral arm flap is a workhorse flap in upper extremity reconstruction. However, its adipofascial variant is not widely used. The technique can be used in various clinical scenarios. The adipofascial flap can be transposed to circumferentially wrap the radial nerve with a pliable, vascularized fat and fascial envelope, mimicking the natural fatty environment of peripheral nerves. This technique has the advantage of providing a scar tissue barrier, a barrier to hardware irritation and a milieu for vascular regeneration of the nerve...
