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.
Objective To investigate and compare the effectiveness of perichondrial cutaneous graft (PCCG) of dorsal auricle for repairing defect after excision of melanocytic nevus in different parts of the face. Methods Between February 2008 and October 2012, 29 cases of facial melanocytic nevus were admitted. There were 11 males and 18 females, aged 3-25 years (median, 11 years). The locations were the upper eyelid in 5 cases, the nose in 15 cases, and the buccal region in 9 cases. The size of the nevi ranged from 1.2 cm × 1.0 cm to 4.0 cm × 2.2 cm. Defects after excision of nevi were repaired by PCCG of the dorsal auricle, which size ranged from 1.5 cm × 1.5 cm to 4.2 cm × 2.5 cm. The postoperative effectiveness was scored by patients according to color match, scar formation, and flatness of the reception site. The satisfaction evaluations were compared by the score among different parts. Results All the PCCG survived. All the patients were followed up 7-15 months (mean, 10 months). All the reception site had good color match and acceptable scar formation. The nasal part had good flatness, and the upper eyelid had poor flatness. Score comparison showed no significant difference in color match between 3 parts (P gt; 0.05). Nasal part had significantly less scar formation than buccal region and upper eyelid (P lt; 0.05), but no significant difference between buccal region and upper eyelid (P gt; 0.05). Nasal part and buccal region both had significantly better flatness than upper eyelid (P lt; 0.05), but no significant difference between nasal part and buccal region (P gt; 0.05). The overall evaluation score of nasal part and buccal region was significantly higher than that of the upper eyelid group (P lt; 0.05), and the score of the nasal part was significantly higher than that of the buccal region (P lt; 0.05). Conclusion PCCG of dorsal auricle has a good color match in repair of facial defect, especially in repair of nasal defect with good flatness and no obvious scar formation.

Methods From April 2008 to November 2009, 28 cases of giant nevus were admitted for skin expander surgery.The nursing interventions，especially the mental nursing, health education and nursing care during the infusion period were summarized and analyzed. Results The results were satisfactory including the color and the appearance by one-year follow-up. Conclusion It is important to emphasize the mental nursing, health education and nursing care during the infusion period for the patient undergoing giant nevus plasty treated with skin expander.
Choroidal nevus is one of the most common benign melanocytic tumor. The prevalence rate of choroidal nevi is 0.15% - 10.00%, which is high among whites and low among colored people, and is obvious higher in male than that in female. Secondary changes in the surrounding retina of the benign tumor, such as subretinal fluid and choroidal neovascularization, may result in vision loss. This benign tumor carries risks for transformation into malignant melanoma. The factors predictive of transformation into melanoma included greater thickness, subretinal fluid, visual symptoms, orange lipofuscin pigment, tumor location (tumor margin near optic disc), ultrasonography hollowness and absence of halo. Early identification of the related features which impair visual acuity is important for early treatment and better prognosis, and it is especially important to monitor the tendency of malignant transformation. Optical coherence tomography (OCT) could provide detailed information which aid in diagnosing, differentiating and monitoring of choroidal nevi. OCT and optical coherence tomography angiography are emerging as excellent techniques to investigate choroidal melanocytic lesions. The treatment modalities, such as laser photocoagulation, photodynamic therapy and intravitreal anti-vascular endothelium growth factor, have been proved to be effective for choroidal nevi with secondary changes. In the future, the relevant researches should be imposed to provide more detailed information in order to explore the nature and characteristics of this disease.
