BACKGROUND The fibular flap and the scapular flap are widely used for immediate reconstruction after segmental mandibulectomy. The aim of this study was to compare perioperative complications between the fibular flap and the scapular flap in immediate mandibular reconstruction. METHODS Data were retrospectively collected on 56 patients who had undergone immediate mandibular reconstruction with a fibular flap (38 patients) or a scapular flap (18 patients) after segmental mandibulectomy from 2005 to 2011. The rates of perioperative recipient-site and donor-site complications were compared between the groups. RESULTS The overall rate of recipient-site complications did not differ significantly between the fibula group and the scapula flap. However, the rate of donor-site complications was significantly higher in the fibula group than in the scapula group. Partial skin-graft loss in the fibula group occurred in as high as 13 out of 38 patients. DISCUSSION For immediate mandibular reconstruction, a scapular flap provides short-term results equivalent to those with a fibular flap but with less donor-site morbidity. The major drawbacks of the fibular flap include prolonged healing of the donor site and the delayed mobilisation of patients. Although our first choice of vascularised bone graft is the fibular flap, the scapular flap in an alternative for those patients, especially elderly patients, in whom fibula harvest can result in significant morbidity.

Background: Prolonged bed rest and elevation have traditionally been considered necessary after free-flap transfer to the lower extremities. In this retrospective study, we tried to mobilize patients early after free-flap transfer to the lower extremity by means of flow-through anastomosis for both arteries and veins. Methods: This study included 13 consecutive patients who underwent immediate free-flap transfer after wide resection of soft-tissue tumors of the lower extremity from March 2012 through July 2013. The defects were above the knee in 5 patients and below the knee in 8 patients. In all patients, flow-through anastomosis was used for both arteries and veins. The patients were mobilized starting on the first postoperative day, and their activities of daily life were gradually expanded, depending on the wound conditions. Postoperative complications and the progression of their activities of daily life were investigated retrospectively. Results: No anastomotic failure or take back occurred. Partial flap necrosis occurred in 1 patient because of a poor perforator but was unrelated to early mobilization. All patients could move to wheelchairs on the first postoperative day. Within 1 week, 12 of 13 patients could start dangling and 10 of 13 patients could start ambulating. Conclusions: This study demonstrates that early mobilization after free-flap transfer to the lower extremity is made possible by flow-through anastomosis for both arteries and veins. Flow-through flaps have stable circulation from the acute phase and can tolerate early dangling and ambulation.

Salvage total pharyngolaryngectomy after failed organ‐preserving therapy often results in composite defects involving the alimentary tract, trachea, and neck skin. This retrospective study examined combined use of the free jejunum flap and the pectoralis major muscle flap with skin graft for such a complex reconstruction. We reviewed 11 patients who underwent free jejunum transfer for alimentary reconstruction and pedicled pectoralis major muscle flap transfer with a skin graft on the muscle for simultaneous neck skin resurfacing after salvage total pharyngolaryngectomy from 2005 through 2010. The operative morbidity rate was 27.3%. No pharyngocutaneous fistula developed in this series. Oral intake could be resumed within 3 weeks after surgery in all patients. Seven of 11 patients had a functional tracheostoma with adequate stomal patency. Combined use of free jejunum and pectoralis major muscle flap with skin graft provided secure wound closure even for complicated cases.

The flow‐through fibula flap utilizing the soleus branch as a distal runoff has not yet been reported. We herein present a patient with left tibial adamantimoma in whom wide resection of the tumor resulted in a segmental tibial defect 22 cm in length. The defect was successfully reconstructed with a flow‐through free fibula osteocutaneous flap using the soleus branch of the peroneal artery as a distal runoff. The short T‐segment of the peroneal artery was interposed to the transected posterior tibial artery. The soleus branch has a constant anatomy and a larger diameter than the distal stump of the peroneal artery. Short interposed flow‐through anastomosis to the major vessels is much easier and more reliable than the conventional methods. We believe that our method represents a versatile option for vascularized fibula bone grafting for extremity reconstruction.

BACKGROUND Percutaneous sclerotherapy is an effective therapeutic option for the treatment of venous malformations. Absolute ethanol is used as a sclerotic agent because of its effectiveness but is often avoided for treatment of superficial lesions because of the possible risk of cutaneous necrosis. OBJECTIVE A preclinical experimental study was performed to validate whether the cytotoxic effects of ethanol on surrounding healthy tissues could be diminished with prophylactic subcutaneous injection of normal saline above the vascular lesion immediately after intraluminal injection of ethanol by dilution. METHODS AND MATERIALS The effect of normal saline dilution on cytotoxicity of ethanol to the main cells of the skin (fibroblasts and keratinocytes) were assessed using 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide colorimetric assay. Effects of subcutaneous injection of normal saline immediately after intraluminal ethanol injection were assessed in a newly developed animal experimental model using the rabbit auricular vein. RESULTS Cytotoxic effects of ethanol were decreased by saline dilution in vitro. Subcutaneous injection of normal saline after intraluminal injection of ethanol prevented the cutaneous ulceration observed in all cases without subcutaneous injection of normal saline in our animal model. CONCLUSION Subcutaneous injection of normal saline appears effective for preventing cutaneous complications after ethanol sclerotherapy for superficial vascular lesions. The authors have indicated no significant interest with commercial supporters.

Combined use of the cephalic vein and pectoralis major muscle flap for secondary esophageal reconstruction

Shimpei Miyamoto; Shuji Kayano; Masahide Fujiki; Minoru Sakuraba

Secondary reconstruction of thoracic esophageal defects is a challenging problem for microsurgeons. Because of previous surgeries and coexisting disease, gastric pull‐up, and creation of a pedicled colon conduit are often impossible. Transfer of a supercharged pedicled jejunum flap or free jejunal interposition is usually the last resort; however, identifying appropriate recipient vessels and adequately covering the reconstructive conduit are often difficult. We performed secondary thoracic esophageal reconstruction with combined use of the cephalic vein as a recipient vein and the pectoralis major muscle flap for coverage in three patients. Two patients underwent transfer of a supercharged pedicled jejunum flap, and the other patient underwent free jejunal interposition. No wound complications occurred, and all patients could resume oral intake. The cephalic vein is a more reliable recipient vein than is the internal mammary vein. The skin graft‐covered pectoralis major muscle flap provides secure external coverage to prevent anastomotic leakage even in complicated cases. Combined use of the cephalic vein and the skin graft‐covered pectoralis major muscle flap is a versatile option for secondary thoracic esophageal reconstruction.

Closing large skin defects of the upper back is a challenging problem. We have developed an efficient design for a latissimus dorsi musculocutaneous flap for reconstruction in this region. The longitudinal axis of the skin island was designed to be perpendicular to the line of least skin tension at the recipient site so that primary closure of the flap donor site changed the shape of the recipient site to one that was easier to close. We used this method for four patients with skin cancers or soft‐tissue sarcomas of the upper back in 2011 and 2012. The size of skin defects after wide excision ranged from 11 × 10 to 25 × 20 cm2, and all skin defects could be covered by the flaps and all wounds of donor site could be closed without skin grafts. No wound complications occurred in any patient. Functional and aesthetic outcomes were satisfactory in all patients. This flap design is effective for reconstructing large skin defects of the upper back.

Reconstructing the trachea is challenging because of its multilayer structure and airway function; multiple procedures are often required. We report a case of one-stage reconstruction for a tracheal defect. The surgery was performed with a free radial forearm flap and free costal cartilage grafts. Air leakage occurred postoperatively but healed without additional surgery. The reconstructed trachea has retained its shape, diameter and airway function for 14 months despite the patients history of radiotherapy. This one-stage procedure with well-vascularised tissue was successfully used to reconstruct a stable, well-functioning trachea.
