APPLICATION OF HEALON FOR CONTROLLING OF GUSH IN THE COCHLEAR IMPLANT SURGERY OUR EXPERIENCE WITH 10 CASES

Abstract

Objective:

The objective of the study is to present our experience on cerebrospinal gush during cochlear implantation controlled by Healon® injection at cocheostomy site.

Material and Methods:

This is a retrospective review of 10 inner ear anomalies patients encountered gush during cochlear implant surgery.

Results:

CSF gush was stopped within a minute and insertion of cochlear electrode was done easily in a clean surgical field. Finally cochleostomy site was packed with pieces of temporalis muscle. Any signs of CSF leak and other major complications weren’t seen on follow up period ranging from 6-27 months on all patients. All postoperative CT scans were available for review, all showing electrodes on scala tympani.

Conclusion:

Injecting healon® at cochleostomy site could be useful simple, early, rapid method to stop CSF gush in addition to facilitate atraumatic deep insertion of active electrodes during cochleostomy.
