【Abstract】 Objective To review the progress of autologous fat grafting of the face and outline different arguments in this field. Methods Recent literature concerning autologous fat grafting of the face was reviewed and analyzed. Results The applications and techniques for autologous fat grafting have been matured increasingly. It not only can adjust the proportion of facial contours, restore tissue volume, but also can improve the local skin texture. Reliable clinical results have achieved in facial augmentation and rejuvenation. Although there are arguments about donor site, harvesting technique, processing technique, and grafting technique, the basic principle is the same. Conclusion From the perspective of evidence-based medicine, clinicians are rich in clinical experience, but objective evidence is insufficient. So further researches should be carried to look for scientific evidences.
ObjectiveTo investigate the effectiveness of modified kite flap in repair of soft tissue defect after divided nevus of lateral canthus excision.MethodsBetween October 2010 and April 2018, 20 children (20 eyes) with divided nevus of lateral canthus were admitted. There were 13 boys and 7 girls, with an average age of 7.9 years (mean, 4-14 years). There were 11 cases of moderate range lesions (maximum diameter, 1.5-2.0 cm) and 9 cases of small range lesions (maximum diameter, <1.5 cm). After excising the divided nevus of lateral canthus, the area of soft tissue defect ranged from 0.72 to 3.23 cm2. The modified kite flap was used to reconstruct the structure and shape of lateral canthus.ResultsThere were 16 cases of mixed nevus and 4 cases of intradermal nevus. The flaps survived and the incisions healed by the first intention. The patients were followed up 12-22 months (mean, 13.6 months). There was no malformation, valgus, exposure keratitis, or obvious scar. No malignant transformation occurred or nevus recurred during follow-up. At last follow-up, the effectiveness was rated as excellent in 16 cases, good in 3 cases, and poor in 1 case.ConclusionThe modified kite flap can repair the soft tissue defect after excising the divided nevus of lateral canthus, and obtain the good appearance and function of lateral canthus.
ObjectiveTo explore the effectiveness of modified rhomboid flap for repairing facial skin and soft tissue defect.MethodsBetween January 2016 and May 2018, 23 patients with facial skin and soft defect were repaired by the modified rhomboid flap. There were 10 males and 13 females with the median age of 27 years (range, 11-72 years). The primary tumor included pigmented nevus in 18 cases, basal cell carcinoma in 4 cases, and squamous cell carcinoma in 1 case. The defect location was nose in 8 cases, cheek in 4 cases, malar in 6 cases, forehead in 2 cases, and upper lip in 3 cases. The defect ranged from 0.8 cm×0.8 cm to 3.9 cm×3.9 cm. According to the location and size of facial tumors, the resection area of square lesions was designed. According to the mobility of surrounding tissues and the direction of dermatoglyphic lines, the rhomboid flaps with an angle of 45–60° was designed to repair the defect by tension-free rotation.ResultsAll the flaps survived and the incision healed by first intension. All patients were followed up 3-15 months (mean, 7.3 months). During follow-up, no tumor reoccurred; the color and texture of the flaps were similar with surrounding tissue. There was no obvious scar hyperplasia, nor traction of adjacent normal tissues, and patients were satisfied with the appearance.ConclusionThe application of modified rhomboid flaps in repairing facial skin and soft tissue defects caused by resection of round facial tumor has the advantages of flexible design, simple manipulation, and less trauma.
