Abstract

Aims The aim of this study was to evaluate the surgical outcome of cavity obliteration with bioactive glass in patients with cholesteatoma undergoing canal wall down mastoidectomy with reconstruction of the canal wall.

Materials and Methods A prospective study was conducted over a period of 3 years on 25 patients who underwent mastoid obliteration with bioactive glass following canal wall down mastoidectomy for cholesteatoma. The primary outcome measure was the presence of a dry, low-maintenance mastoid cavity that was free of infection, assessed, and graded according to the grading system by Merchant et al at the end of 1 and 6 months postoperatively. Secondary outcome measures included presence of postoperative complications like wound infection, posterior canal wall bulge, and residual perforation.

Results Out of the 25 patients on whom this study was conducted, at the end of 1 month 60% had a completely dry ear, 28% of patients had grade 1, and 12% had grade 2 otorrhea at the end of the first month. At the end of 6 months, 72% had a completely dry ear, while 20% had grade 1 and 8% had grade 2 otorrhea. There were no cases with grade 3 otorrhea during the entire follow-up period. Postoperative complications of the posterior canal bulge were noted in two patients (8%), and one patient (4%) had a residual perforation.

Conclusion Mastoid cavity obliteration with bioactive glass is an effective technique to avoid cavity problems.
