Management of Spontaneous Cerebrospinal Fluid Otorrhea

Abstract

Spontaneous CSF otorrhea is uncommon and often not diagnosed until a myringotomy or tympanostomy tube is placed. The middle fossa craniotomy provides the best exposure for defects involving the middle fossa floor. Both alloplastic and autologous materials are highly successful in repairing the defect(s) responsible for CSF otorrhea. No infections of the alloplastic bone cement occurred in our series.
