The kissing nevus is a rare form of congenital melanocytic nevus. We present a case of a 4-year-girl with kissing nevus on the right eyelids. As a treatment, we used a tissue expander. In the first operation, The 16 cc sized rectangular-shape tissue expander was inserted within the subcutaneous layer at the right zygomatic area. After expansion for 5 months, local advancement flap was performed for lower eyelid reconstruction, and interpolation flap was carried for the upper eyelid. The remnant interpolation flap was removed and trimmed after 3 weeks. We report here a rare case of the kissing nevus on the eyelids that showed good results after reconstruction using a tissue expander.

A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.

BACKGROUND: Serial tissue expansion is performed to remove giant congenital melanocytic nevi. However, there have been no studies comparing the expansion rate between the subsequent and preceding expansions. In this study, we analyzed the rate of expansion in accordance with the number of surgeries, expander location, expander size, and sex. METHODS: A retrospective analysis was performed in pediatric patients who underwent tissue expansion for giant congenital melanocytic nevi. We tested four factors that may influence the expansion rate: The number of surgeries, expander location, expander size, and sex. The rate of expansion was calculated by dividing the ‘inflation amount’ by the ‘expander size’. RESULTS: The expansion rate, compared with the first-time group, was 1.25 times higher in the second-or-more group (P=0.04) and 1.84 times higher in the third-or-more group (P < 0.01). The expansion rate was higher at the trunk than at other sites (P < 0.01). There was a tendency of lower expansion rate for larger expanders (P=0.03). Sex did not affect the expansion rate. CONCLUSIONS: There was a positive correlation between the number of surgeries and the expansion rate, a positive correlation between the expander location and the expansion rate, and a negative correlation between the expander size and the expansion rate.
