Free tensor fascia lata perforator flap as a backup procedure for head and neck reconstruction

Free tissue transfer is an essential part of the head and neck reconstruction. Despite several flap options, free perforator flaps have become very popular for head and neck. Anterolateral thigh perforator flap has multiple advantages among other options and is preferred by most of the reconstructive microsurgeons. Besides its advantages, sometimes it is impossible to harvest an anterolateral thigh perforator flap, and the surgeon has to shift to another option. Between January 2002 and June 2005, 5 tensor fascia lata perforator flaps were used for head and neck reconstruction because anterolateral thigh perforator flap could not be elevated due to absence or insufficient musculocutaneous perforators. Only 1 flap was reexplored and salvaged by redoing the venous anastomosis. All flaps survived without any other problem. Donor sites were covered by split-thickness skin grafts in 4 patients and closed directly in 1 of them. Doppler examination is important in planning of anterolateral thigh perforator; if the signals of the perforators are absent or very weak, the surgeon can shift to another flap. This decision may also be made during the operation when insufficient perforators are seen. Based on our experience, tensor fascia lata perforator flap is a safe alternative when anterolateral thigh perforator harvest is not possible. Tensor fascia lata perforator flap can be harvested from the same anatomic region with almost same morbidity.

Internal mammary artery perforator flap for head and neck reconstruction

Background: The internal mammary artery perforator (IMAP) flap is a useful modification of the classic deltopectoral flap that has a number of important roles in head and neck reconstruction. Methods and results: In this report, we describe the technique used to plan and raise the flap and demonstrate its use in three different clinical scenarios. Results and conclusions: The IMAP flap is a pedicled fasciocutaneous flap that is based on single or multiple internal mammary artery perforators. As such, it provides thin pliable tissue with a wide arc of rotation that is suitable for cutaneous, pharyngeal and tracheostomal reconstruction. Moreover, the flap is well‐vascularised, reliable and the donor site can be closed primarily.     

Combined radiological and surgical treatment of arteriovenous malformations of the head and neck.

Arteriovenous malformations (AVMs) are high-flow lesions. More than 50% of all AVMs are located in the head and neck region. They represent a therapeutic challenge because of their hemodynamic characteristics and their modality of growth. AVMs have a tendency to recur and often require radical resection, making surgical ablation and reconstruction difficult. AVMs require angiography not only for diagnostic purposes but as an initial therapeutic step in the form of embolization. Surgical ablation, which follows a few days after embolization, is facilitated by the reduction in vascularity and shrinkage of the lesion, both of which are afforded by the embolization. These benefits allow for less blood loss at the time of ablation, and less extensive resection. The authors report their experience with 16 patients with extracranial AVMs of the head and neck examined over the last decade.     

Free flap reconstruction in head and neck oncology

This paper reviews the role of free flap reconstruction following surgical resection of head and neck tumours. The process of selection of the various types of flaps for each specific defect is discussed. Challenges facing the reconstructive surgeon are reiterated.     

Free medial sural artery perforator flap for resurfacing distal limb defects

BACKGROUND: The need for thin flap coverage has increased, especially for contouring or covering shallow defects of distal limbs. The free medial sural artery perforator flap harvested from the medial aspect of the upper calf can be useful for this purpose. METHODS: Between January 2002 and February 2003, we used the free medial sural artery perforator flap for distal limb reconstruction in 11 clinical cases, including four hands and seven feet. This perforator flap is based on the proximal major perforator of the medial sural artery, which can be identified along the axis of the medial sural artery and usually emerges in an area between 6 and 10 cm from the popliteal crease and approximately 5 cm from the posterior midline of the leg. RESULTS: Most of the flaps were safely raised with a single perforator. One flap developed venous congestion during the postoperative course and finally underwent total necrosis. CONCLUSION: The main advantage of the medial sural artery perforator flap is that it only requires cutaneous tissue to achieve better accuracy in reconstructive site, and it preserves the medial gastrocnemius muscle and motor nerve to minimize donor-site morbidity. However, the tedious process of intramuscular retrograde dissection of the perforator and the unsightly scar of the donor region are the major concerns.     

腓动脉穿支腓肠神经营养血管游离皮瓣修复手足软组织缺损

Objective To report the operative techniques and clinical results of the free psroneal artery perforator sural neurecutanecus flaps. Methods Free sural neurocutaneous flap with a single unit of perforating veins and artery arising from the peroneal artery was designed to repair skin defects of hand or from the ankle to distal end of the foot. After the flap was transposed to the defect, the perforating artery was anastomozed with a branch of a nearby artery, and the small saphenoas vein was anastomosed with the cephalic vein or the great sapheneous vein to establish the flap's circulation. An alternative way was to anastomose the perforating vessels only. The sural nerve was anastomosed to innervate the flap. Results From Jan 2005 to Dec 2007, 12 cases were treated with the flaps with no flap necrosis. The size of the flaps ranged from 12 crux7 cm to 18 cm× 11 cm. The follow-up period was 7 to 27 months. Both the cosmetic and functional results were satisfactory. Two point discrimination was 7 ～ 12 mm. Conclusions The flap has all the advantages of the h'ee flap, the perforator flap and the neurocutaneous flap. It is easily performed with reliable blood supply. It's a good choice for repairing the skin defects of hands and feet.
