Bioactive glass S53P4 in mastoid obliteration surgery for chronic otitis media and cerebrospinal fluid leakage.

OBJECTIVES

We evaluated the results of cases of chronic otitis media treated with mastoid obliteration surgery using bioactive glass S53P4.

METHODS

Twenty-five patients with chronic otitis media and 1 patient with cerebrospinal fluid leakage without chronic infection were treated with bioactive glass S53P4. Twenty patients had had previous surgery because of chronic otitis media with or without cholesteatoma. A mastoid obliteration was performed with bioactive glass S53P4 granules and a musculoperiosteal flap with or without bone paté. In 2 patients with a bony dehiscence at the middle cranial fossa, a bioactive glass plate was used to support the protruding dura. In addition, in 3 patients, occlusion of a dural fistula was needed The median follow-up period was 34.5 months (range, 1 to 182 months).

RESULTS

Excluding the 2 patients with only 1 month of follow-up at our department, 96% of the patients had a dry, safe ear or only intermittent otorrhea. In 92% of the patients, the objective of achieving a smaller or nonexistent cavity was achieved.

CONCLUSIONS

Bioactive glass S53P4 is a noteworthy material in mastoid obliteration surgery.
