Single Layer Biomaterial Repair of Frontal Sinus Encephalocele in a Pediatric Patient.

INTRODUCTION

Reconstruction of skull base defects are determined by size, location, and complexity of the defect.

METHODS

Case report.

CASE DISCUSSION: An 11-year old girl presented with a right frontoethmoidal encephalocele after an episode of meningitis. An endoscopic approach was performed with a Draf III to provide exposure. The skull base defect extended superolateral over the orbit, which limited the choice of reconstructive options. The defect was successfully repaired with a single layer onlay graft of bovine collagen matrix.

CONCLUSIONS

Single layer repairs using commercial biomaterials should be considered where multilayer closure or vascularized flaps may not be possible. Laryngoscope, 131:E1750-E1752, 2021.
