Endoscopic resection of intracranial dermoid cysts

Abstract

AbstractIntroduction:Nasal dermoid cysts are congenital lesions which are often diagnosed in infancy or childhood. However, a small number present in adulthood, and some extend intracranially. Traditional treatment for the intracranial portion of these cysts includes frontal craniotomy.Case reports:Two intracranial dermoid cysts were resected via a transnasal endoscopic approach, using 70° nasal endoscopy for complete visualisation and intracranial tumour removal. We describe our technique for the procedure itself and for reconstruction of the skull base defect.Discussion and conclusion:The endoscopic transnasal skull base approach is an excellent alternative to a traditional frontal craniotomy, to achieve complete resection of intracranial dermoid cysts.
