Since R.Y. Song(1982) has reported anatomic studies about septocutaneous perforator flap, various experiences especially on thigh flaps pedicled on septocutaneous artery were reported. Baek(1983) reported an anatomic study through the cadavers dissections on medial, lateral thigh area and provided the first new cutaneous free flap of thigh for clinical use. Song, et a1.(1984) reported anterolateral thigh free flap, Koshima, et al.(1989) reported pedicle variations and its versatile clinical usages. According to their reports, accessory branches of lateral femoral circumflex artery are placed in comparatively constant location and proved to be the effective pedicle of this flap. The advantages of anterolateral thigh free flap are 1) comparatively thin 2) can obtain sufficiently large flap 3) can contain cutaneous nerve 4) can be easy to approach anatomically because pedicle is located in comparatively constant position 5) minimal donor site morbidity. We report the experience of 10 cases of anterolateral thigh free flap coverage for soft tissue defects: 4 cases of soft tissue defects on foot area, 2 cases of soft tissue defects on hand, 3 cases of partial tongue defects owing to tongue cancer ablation, and 1 case of soft tissue defect on nasal alar.

The rectus abdominis myocutaneous flap is frequently used in the field of plastic and reconstructive surgery such as breast reconstruction and as a donor of free tissue transfer. Major problems with this flap is bulkiness, the possibility of postoperative abdominal herniation and muscle weakness following the removal of the rectus abdominis muscle. We used paraumbilical perforator based skin flap fed by a muscle perforator from the deep inferior epigastric artery, with no or little muscle and fatty tissue, in three patients for the resurfacing of relatively wide and thin defects. This technique has all of the advantages of the conventional rectus abdominis myocutaneous flap with decreased possibility of postoperative abdominal herniation or muscle weakness. Another challenging merit is possibility of skin flap thinning.

The radical surgery required for head and neck cancer is sometimes crippling and disfiguring often forcing the patient to live a life of a recluse. Reconstructive surgery is a bridge which allows for aggressive tumor resection while maintaining a quality of life. The ideal reconstructive procedures must be reliable and be performed at the time of resection with only one stage. The use of the free flap by microvascular technique is an ideal method which satisfies the demands of reconstruction, and has been accepted rapidly in the majority of head and neck cancer centers. Since head and neck cancer treatment is one of the major problems demanding multi-disciplinary cooperation, reconstruction with free flap technique has been performed with integral team of head and neck cancer in Ajou University Hospital from September 1994. Herein, we report our analysis of cases regarding various factors in reconstruction. This report demonstrates that microvascular free tissue transfers can be done with high degree of reliability on a wide spectrum of cancer ablative surgical defects using a wide variants of flaps.
