Use of Acellular Dermal Matrix in Craniosynostosis.

Abstract

In craniofacial surgery, a wide spectrum of pathological conditions are usually treated. The aetiology of these could be congenital, traumatic, infective, post-tumor resection, postradiation, autoimmune, iatrogenic, or other miscellaneous conditions. The surgical approach for the procedures is usually via a coronal incision. In a large proportion of the patients, the frontal bone is removed to obtain intracranial access. The frontal bone is then replaced either in its original form or in a remodeled state. In congenital conditions the supraorbital bar and frontal bone is often also removed, remodeled, and replaced. One of the common late sequelae following craniofacial surgery is contour irregularities of the frontal region. These irregularities can vary in their extent. They are invariably palpable and often visible. Surgeons have attempted various methods to improve the contour irregularities. Despite these measures contour irregularities can still ensue. In the authors' unit, the authors have been using acellular dermal matrix in an attempt to diminish the contour irregularities in the frontal region following craniofacial reconstruction for craniosynostosis. This has been used in 35 patients undergoing craniosynostosis correction. Of the 35 patients, 12 were for plagiocephaly, 7 for brachycephaly, 10 for scaphocephaly, 4 for trigonocephaly, and 2 for combined coronal and metopic synostosis. The age of the patients ranged from 5 months to 12 years (mean 20.5 months). There were 21 males and 14 females. The follow-up ranged from 10 to 48 months (mean 23 months).
