The comedo skin reaction to radiotherapy.

A 50-year-old man had a maxillectomy and post-operative radiotherapy for squamous carcinoma of the maxilla. The acute skin reaction merged at 2 months into a chronic comedo-type acneiform skin reaction in the irradiated area. Previous literature on this reaction to radiation is reviewed. The reaction is rare and occurs mostly in the head and neck area, more commonly in patients who have received acneigenic drugs, and with a latent period of between 2 weeks and 6 months from completion of radiotherapy. The pathogenesis of acne is discussed and a mechanism of post-irradiation acne is suggested.

The submental island flap.

The submental island flap is a reliable source of skin of excellent colour, contour and texture match for facial resurfacing and leaves a well hidden donor site. The flap is safe, rapid and simple to raise. We report on its use in 12 cases of facial or intraoral reconstruction. Complications were few. However, there was one case of complete flap loss following its use in a reverse flow manner, due to the presence of an unreported, but constant, valve in the venous system of the face. We believe this flap to be a worthwhile addition to the existing surgical armamentarium.

Experience with 50 free TRAM flap breast reconstructions.

The data from the first 50 patients undergoing free TRAM flap breast reconstruction in two units were examined. Average patient age was 42 years, and average weight was 62 kg. Forty percent of patients were chronic smokers, and 26 percent had low abdominal scars. Twelve percent exercised their abdominal muscles regularly. Eighteen percent had undergone radical mastectomy, whereas 76 percent had undergone modified radical mastectomy and 6 percent had undergone subcutaneous mastectomy. Postoperative radiotherapy had been given in 16 percent of patients, and 54 percent had received postoperative chemotherapy. The average time from mastectomy was 32 months, whereas six breasts were reconstructed immediately. Average operating time was 5.6 hours, and average blood loss was 2.4 units. Average hospital stay was 11.2 days. Complications included three total flap losses (6 percent) and two partial flap losses (4 percent). Abdominal hernia occurred in two patients (4 percent).

Reducing morbidity in the radial forearm flap donor site.

The radial forearm flap, although widely used, has been criticized for the poor quality of its donor site. To investigate the causes of morbidity, 100 radial artery free-flap donor sites have been reviewed. Sixty-seven patients required skin grafting (group 1), and the remaining 33 patients were closed directly (group 2). Seventeen patients in the series had compound osteocutaneous flaps (group 3). Wound healing proved to be a significant problem in groups 1 and 3, and fracture of the radius occurred in 4 of the 17 patients in group 3 and was the most significant cause of morbidity. The radial artery was reconstructed in 12 patients, but only 6 of the arteries (50 percent) were patent at the time of review. Subjective assessment on a scale of 0 to 10 demonstrated a relatively pain-free donor site with low pain scores (2.5 of 10). The cosmetic result was acceptable in men (1.5 of 10) but was less so in women (4 of 10). Angulated fracture of the radius produced an unacceptable cosmetic result (7 of 10). In light of this experience, we no longer reconstruct the radial artery as a matter of routine. The donor defect is closed directly wherever possible using an ulnar artery-based transposition flap when required. A "boat shaped" osteotomy is used in preference to right-angled bone cuts when harvesting a segment of radius to avoid the complications and sequelae of fracture. These changes in surgical technique have improved the acceptability and minimized the problems associated with this donor site.

Direct closure of the radial forearm flap donor defect.

A method of direct closure of the donor defect of the radial forearm flap is described. This avoids the complication of delayed wound healing which remains a problem after split skin graft reconstruction.

The bi-scapular flap.

The free transfer of two transverse scapular flaps in continuity is described. This provides a donor site capable of yielding a skin flap 50 x 10 cm. Some observations on the vascularity of adjacent axial territories are made.

Primary reconstruction of a severed ear fragment using a flap of temporo-parietal fascia.

The temporo-parietal flap is used for primary reconstruction of a severed ear fragment, salvaging the cartilage framework of the amputated part.

Human bites: a review.

Forty-one human bites of the face are presented with a comparative review of earlier published series. Their primary treatment is outlined. The majority of bites presented few initial complications due to the excellent blood supply of the face and the use of prophylactic antibiotics. Secondary reconstruction, however, usually entailed multiple staged operations.

The injured ear: a review of 50 cases.

In a retrospective review of 50 patients with wounds of the ear, simple closure was found preferable to flap repair as a method of primary treatment. Replantation of the partially or totally amputated ear as a composite graft was singularly unsuccessful in this series.
