Lower limb soft tissue reconstruction using microsurgical techniques.

Trauma is the main cause of lower limb soft tissue defects followed by tumor resection, vascular disease and osteomyelitis. 17 patients were operated on using microsurgical techniques during the last 10 years. 9 of the patients had traumatic defects, 5 had various malignant tumors, 2 patients had arterial insufficiency and finally 1 patient had chronic osteomyelitis. The latissimus dorsi either as muscle flap with a split thickness skin graft or as a musculocutaneous flap was used the most frequently in our series. Other flaps, including the radial forearm neurovascular flap, the rectus abdominis flap, the scapular flap, the groin and the dorsalis pedis flaps were used less often. Delayed primary cover was used, except in 1 case with an opened knee joint trauma, where emergency repair was performed. Complications included: 2 partial skin graft necroses which required revision and 2 flap necroses caused by venous thrombosis. With follow-up more than 4 years in all but 2 patients, functional results were found satisfactory. Cosmetic results, however, were less satisfactory.

Use of the latissimus dorsi flap in head and neck reconstructive microsurgery.

Reconstructive surgery of the head and neck has particularly benefited from the rapid developments in microsurgery. Resection of tumours from the head and neck which are associated with serious physical and psychological problems, or which often require multiple reconstructive procedures, can now be performed as a single-stage procedure with good oncological and functional results. The present series reports on the treatment of 12 primary or recurrent malignant tumours of the head and neck using the latissimus dorsi musculocutaneous free flap. Complications consisted of two venous thromboses which required revision of the anastomoses. The oncological and functional results were good, while the aesthetic outcome was fair. We conclude that the latissimus dorsi muscle or musculocutaneous free flap is the method of choice to repair wide defects of the head and neck following the resection of malignant tumours.

Platysma myocutaneous flap for intraoral and surface reconstruction.

Different procedures have been described for facial and oral reconstruction after malignant tumor removal, such as skin grafts and local and distal staged flaps. Myocutaneous island or free flaps are the method of choice for these reconstructions. Our experience concerns the use of the platysma myocutaneous flap in 12 patients after intraoral and extraoral malignant tumor resection. Six patients had squamous cell carcinomas, i.e., 2 malignant melanomas of the skin and 4 squamous cell carcinomas of the oral mucosa. The complete tumor resection was controlled by frozen-section biopsy in all patients, but for 7 of them a functional or radical neck dissection was performed. We suggest including in the flap the external jugular vein. The results were evaluated from an oncological, functional, and aesthetic point of view. We noticed 2 recurrences in a minimum follow-up of 4 years. The functional and aesthetic results were quite satisfactory and no serious complications were noticed in our series. However, the primary disadvantage of this interesting flap is that the dominant vasculature derived from the submental branch of the facial artery is seldom visualized. In spite of this, it should be regarded as very useful for limited intraoral or surface coverage problems in an arc extending 10 cm from the level of the facial artery at the mandible. This arc includes the cheek, the lower lip, the chin, the floor of the mouth, and the mastoid area.
