Tissue expansion in children: a retrospective study of complications.

We retrospectively reviewed 105 consecutive children in whom 191 tissue expanders were placed by the Plastic Surgical Service at The Children's Hospital from 1987 to 1995. The age range was 1 month to 28 years. The series included 68 females and 37 males. The indications for tissue expansion were congenital pigmented nevus (N = 55), craniofacial anomaly (N = 13), aplasia cutis congenita (N = 7), meningomyelocele (N = 7), posttumor resection (N = 5), unstable scar (N = 4), burn scar (N = 3), and miscellaneous disorders. The expanders were located in the scalp (N = 59), cervicofacial area (N = 23), back (N = 18), chest (N = 6), and extremities (N = 6). A single expander was used in 47 patients and the mean number of expanders per patient was 1.8. All patients were given preoperative intravenous antibiotics. There were 25 complications in 20 patients (19%), which comprised 13% of all expanders. The most common complications were infection (6%, N = 11), deflation (3%, N = 6), and exposure (2%, N = 5). These complication rates were not related to either the gender, site of implantation, number of expanders, use of closed suction drains, or the indication for expansion. The complications were related to age, being higher in children (age 1-12 years) compared with infants and adolescents. Tissue expanders can be successfully used in children to construct and reconstruct a variety of cutaneous defects, but there is an irreducible minimum for the three major complications.

Ear replantation without microsurgery.

Reconstitution of the amputated ear remains a challenge to the plastic surgeon. Reattachment as a composite graft of the total or subtotal amputated ear is unreliable. Microsurgical replantation can be performed in a minority of cases; however, difficulty with adequate venous drainage complicates the technical complexity of these cases. To enhance survival of a reattached ear segment, Mladick et al. advocated use of the retroauricular pocket principle. This technique involves deepithelialization of the amputated part, followed by anatomic reattachment to the amputation stump and then burial in a retroauricular pocket. This simple technique increases the surface area of the avulsed segment in contact with surrounding nutrients, maximizing the probability of "take." The relationship between the dermis and cartilage is preserved, thus minimizing the deformity from cartilage warping. The undisturbed dermis on the involved segment can reepithelialize spontaneously, negating the need for a skin graft. We have used this technique successfully in five of six patients.
