Reconstruction After Posterior Cranial Fossa Surgery—Case Report of Application of a Synthetic Tissue Sealant to Augment Dural Closure

Abstract

Cerebrospinal fluid (CSF) leakage following cranial surgery is a well-described and potentially devastating complication, particularly in posteriorcranial fossa surgery. If untreated, a persistent CSF leak can evolve into wound breakdown, a surgical-site infection, and meningitis. Themorbidity of a complication following a cranial operation is harmful to the patient. Additionally, complications are a source of elevated medicalcosts. Numerous reconstruction strategies have been developed to thwart the ill effects of CSF leaks on patient outcomes and healthcarefinances. This case report illustrates the method employed at our institution to repair posterior fossa defects following surgery in thecerebellopontine angle.
