Key Points
- A mastoid cavity presents significant morbidity to the patient and
burden on the clinical service.
- Obliteration of the mastoid cavity aims to prevent these problems and
improve patients quality of life.
- Bioactive glass provides a safe and effective means of mastoid
obliteration without extensive dissection of a soft tissue flap to
fill the defect.
- The most common complication suffered by patients is an increased
frequency of attendance in the initial healing phase as the graft
covering the bioactive glass develops a blood supply and epithelises.
- In our experience bioactive glass can be placed onto dehiscent facial
nerve and dura without complication.
