SerenoCem -glass ionomeric granules: a 3-year follow-up assessment of their effectiveness in mastoid obliteration.

A chronically discharging cavity is a complication of canal-wall down mastoidectomy procedures. Mastoid obliteration can reduce this otorrhoea, with many techniques and materials for obliteration described. This study assesses the effectiveness of SerenoCem granules in providing successful obliteration, by recording the need for subsequent aural care and patient satisfaction using the Glasgow Benefit Inventory. All ears were made dry by the procedure (three after revision). Aural care visits reduced [down 9.2 (95% CI 4.7-13.8) over 2 years] and quality of life benefited [total postoperative Glasgow Benefit Inventory score 21.8 (95% CI 10.1-33.6)] significantly, suggesting that SerenoCem granules are a useful biomaterial to consider in mastoid obliteration. Postoperative infection can prevent osseointegration of the SerenoCem.
