Acellular Dermal Matrix as a Definitive Reconstructive Option for Management of a Large Myelomeningocele Defect in the Setting of Severe Lumbar Kyphosis.

Abstract

Severe kyphosis is infrequently seen in neonates with myelomeningoceles. Spinal skeletal dysmorphology complicates repair, as local tissue may be insufficient to cover the dural repair. Although neonatal kyphectomy has been proposed as a potential solution to this problem, it carries significant potential risks that may not be acceptable to families. A neonate presented with a large myelomeningocele defect with associated severe lumbar kyphosis. Kyphectomy was both declined by the family owing to the potential surgical risks and deemed not appropriate by the surgeons based on the challenging anatomic considerations. Soft tissue closure was not possible with local tissue rearrangement. Acellular dermal matrix was used as a definitive soft tissue coverage option, with complete epithelialization noted at 8 weeks postoperatively. Acellular dermal matrix is a potentially useful adjunct for definitive reconstruction of complex neonatal soft tissue defects where local tissue is not available.
