A Case of Congenital Inner Ear Anomaly Combined with Cerebrospinal Leak Using Hydroxyapatite Cement for Treatment / 대한이비인후과학회지

ABSTRACT

Cerebrospinal fluid otorrhea is a rare disease entity, especially when brought on by spontaneous causes. The site of leakage should be identified to treat the disorder effectively. Various localizing modality was suggested in the literatures. Intrathecal gadolinium-enhanced magnetic resonance imaging identifies the small leakage site easily and correctly. Hydroxyapatite cement is a calcium phosphate-based material that forms dense paste mixed with water or sodium phosphate solution. Hydroxyapatite cement is remarkable for its excellent biocompatability in interacting with the native bone to osseointergrate with the surrounding bone. We report on our experience of successfully treating a patient with the cerebrospinal fluid leak from the congenital inner ear anomaly using the hydroxyapatite cement.
