Abstract:
The Codman ETHISORB Dura Patch is a synthetic, absorbable material whose absorption is complete within approximately 90 days. We report the first case of an unabsorbed Codman Dura patch, in which a patient was presented with nasal obstruction and epistaxis 8 years after pituitary surgery for Cushing's disease.
