조직확장술을 이용한 연조직 재건 = SOFT TISSUE RECONSTRUCTION WITH TISSUE EXPANSION

다국어 초록 (Multilingual Abstract)

Over the 7 years, we have used tissue expansion technique to achieve soft tissue reconstruction in 61 patients with various kinds of congenital or acquire defects of the scalp, face, trunk, and extremities. Of these patients, 25 were male and 36 were female, ranged in age from 5 to 36 years(mean 21). Burn scar(44%) was the most common indication and the rest of them were traumatic scar, microtia, tumor, nevus, vascular malformation, paraffinoma, and cleft lip scar. Twenty five expansions were performed in the face, 12 in the scalp, 9 in the upper extremity, 7 in the ear, 5 in the neck, 4 in the lower extremity, and 1 in the trunk. Rectangular shaped prosthesis with remote internal reservoirs were most commonly used types, and the expander volume ranged from 1.5 to 1,100 mL. Every expander was prefilled to 21 percent of its volume in average and inflation was begun about 2 weeks after implantation. The process was repeated at weekly intervals until adequate tissue expansion was obtained. Expansion period ranged from 2 to 31 weeks(mean 13). Hyperexpansion(mean 130%) was a rule in this series, allowing a skin surplus for reconstruction.
Clinical assessment was done with an excellent result of 37%, especially in the scalp. Twenty two percent of the patients had complications requiring specific treatment with consequent alteration of the treatment plan. The most common complication was prosthesis exposure.
