Hypothesis
Is glass ionomer cement effective for ossicular chain reconstruction after removing an active middle ear implant?
Conclusion
Glass ionomer cement is an effective method for closing the air-bone gap after the removal of an active middle ear implant.
Supporting Evidence
- 60% of short-term patients achieved an air-bone gap of 0 to 10 dB.
- 80% of long-term patients achieved an air-bone gap of 0 to 10 dB.
- The overall mean air-bone gap for all subjects in Group A was 11.2 dB.
- The overall mean air-bone gap for all subjects in Group B was 9.8 dB.
Takeaway
Doctors used a special glue to fix a part of the ear after taking out a device, and it worked really well for most patients.
Methodology
This study reviewed postoperative audiometric data from 15 subjects who underwent ossicular chain reconstruction using glass ionomer cement after explantation of an active middle ear implant.
Potential Biases
Potential bias due to the retrospective nature and lack of control group.
Limitations
The study is retrospective and noncontrolled, with small sample sizes limiting statistical power.
Participant Demographics
Average age of participants was 63 years, with 5 females and 10 males.
