Reconstruction of traumatic short nose with iliac bone graft and nasolabial flaps.

Nasolabial flaps are beneficial in reconstruction of partial defects in the nose. Two nasolabial flaps and an iliac bone graft were used in one-stage reconstruction of a traumatized short nose. One flap filled the lining defect, while the other covered the skin defect. The two flaps were simultaneously transposed as subcutaneous pedicle flap, and this enabled easy mobilization of the flaps. An L-shaped iliac bone graft placed between the two flaps could maintain an unobstructed airway and the shape of the nose.

Experience with free composite tissue transplantation based on the deep circumflex iliac vessels.

Eight free iliac osteocutaneous flaps and three vascularized iliac bone grafts based on the deep circumflex iliac vessels were transferred in 11 cases of large skin and bone or bone defects. Seven of the eight osteocutaneous flaps took successfully. The eighth demonstrated partial necrosis. There was complete bone union in ten cases, and no union in one case as a result of persistent infection. Based on this experience, we concluded that free osteocutaneous flaps based on the deep circumflex iliac vessels have the following advantages over free osteocutaneous flaps based on the superficial circumflex iliac vessels: the pedicle is long (5 to 7 cm); the nutrient vessels are large (artery: 2.2 mm; vein: 2.5 mm); the anatomic course of the vessels is constant; and there is a large amount of bone available.

Everting method: a new modification to obtain reliable microvascular anastomosis.

We have developed a new microvascular technique for anastomosing small vessels in various situations. The factor of prime importance in achieving high patency rates has been the accurate approximation of the intima at the suture site. In our everting method, the adventitia is never exposed to the lumen, and the intima is well coapted. The everting method is simple to perform and so may also be extensively applied to macrovascular surgery.

Microvasular free flap transfer in reconstructive surgery.

The perfection of micro-suture of small vessels has enabled trnasplantation of various large composite tissues by anastomosing their nutrient vessels directly to suitable vessels in the recipient site. Among them, the so-called free skin flap has many advantages over the conventional flap methods for covering the complicated defects of the skin and subcutaneous tissues. In this paper, the author introduces the representative free skin flaps on the basis of his 300 clinical free flap experiences.

Clinical application of free omental flap transfer.

In the field of reconstructive surgery, the greater omentum has been used as a transposed flap for the treatment of chronic lymphedema, radionecrosis, and so forth. Its transferable range was limited by the length of its pedicle. Microvascular anastomosis allows for free transplantation of this organ and has vastly expanded its usefulness.
