RESUMEN
Little has been written about reconstructive methods after resection of melanomas in the head and neck region. We investigated reconstructive methods retrospectively related to the site and size of the melanomas resected by examining the medical records of 28 patients who had malignant melanomas of the head and neck resected at our hospital from 1984 to 2001. The tumour distribution was 12 in the cheek, 6 in the conjunctiva, 2 in the upper lip, 2 in the lower lip, one each in the lower eyelid, eyebrow, scalp, nose, and auricle. Reconstructive methods were 18 skin grafts, seven local flaps, and three free flaps. Three patients who had skin grafts required secondary reconstruction using free flaps. No local recurrences were observed. Reconstructions with local flaps give better aesthetical and functional results than free flaps and skin grafts. Immediate reconstruction with a flap is safe and it does not affect observation of local recurrences.

BACKGROUND: Few published large series have described a surgical approach to maxillary skeletal reconstruction on the basis of the extent of maxillectomy. METHODS: We have reviewed a 10-year experience with 38 consecutive maxillary reconstructions with respect to maxillectomy defects, reconstructive procedures, reconstructed buttresses, and functional and aesthetic outcomes. RESULTS: Maxillectomy defects were classified into three categories on the basis of the buttress concept. Buttress reconstruction was most frequently performed in category III maxillary defects (56%), followed by category I (50%) and category II (20%). The vascularized composite autograft included the rectus abdominis myocutaneous free flap combined with costal cartilage, and the latissimus dorsi myocutaneous free flap combined with the V-shaped scapula is an effective method for reliable reconstruction of both skeletal and soft tissues. CONCLUSIONS: A critical assessment for skeletal defects and associated soft tissue defects is essential for an adequate approach to solve complex problems in maxillary reconstruction. On the basis of retrospective analysis of this series, a reconstructive algorithm for surgical management of maxillectomy defects is proposed.

BACKGROUND: Although gastric tubes are commonly used in thoracic esophageal reconstruction, sometimes circumstances are such that an alternative method must be found. On these occasions, pedicled jejunum transfer and colonic interposition are used. After reconstruction, partial necrosis can occur because of poor blood flow in the oral end of the segment used to restore esophageal continuity. To improve this blood flow, we created a technique-the "supercharge" technique-in which we perform additional microvascular blood flow augmentation. METHODS: The supercharge technique was performed in 82 esophageal reconstructions with microvascular blood flow augmentation. Reconstructive methods included a gastric tube in 5 patients, a gastric tube combined with a free jejunal graft in 2, an elongated gastric tube in 6, a pedicled colonic interposition in 26, and a pedicled jejunum in 43. Recipient vessels were located in the neck or chest regions. RESULTS: After microvascular blood flow augmentation, the color and blood flow of the transferred intestine appeared greatly improved. During the operation, thrombosis was noticed in 3 patients and successfully salvaged by reanastomosis. Partial graft necrosis of the oral end of the segment occurred in only 2 patients; 2 patients had anastomotic leakage. CONCLUSIONS: The risk of leakage and partial necrosis of the transferred gut conduit appear to be reduced by using the supercharge technique to augment microvascular blood flow. This reliable technique contributes to the successful reconstruction of esophageal defects.
