Introduction: Since decades, many different materials have been used to obliterate mastoid cavities, often with only little success. Since 2012, we have used the glass granules BonAlive®. The results are critically reviewed.

Material/methods: Within a period of 2 years, BonAlive® has been used in 100 surgeries. Retrospectively, the anamnestic data, in particular the number of prior surgeries, the audiometric data pre- and post-operatively, and the healing process was analyzed.

Results: Pre- and post-operatively there is no significant change in the Air-Bone-Gap. In very few cases, and subject to anamneses which show decades of inflammatory processes of the mastoid cavity, the healing process can be a maximum of 5 months. Failures, for example due to material extrusion, have not been observed. The revision rate within the period observed was below 5%, and the glass granules were not the cause of the revision.

Conclusion: BonAlive® is a suitable material for obliterating mastoid cavities. Based on a critical evaluation of the results, recommendations are made for surgery.
