Hypothesis
Is glass ionomer cement effective for ossicular chain reconstruction after removing an active middle ear implant?
Conclusion
The study found that 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 the short-term group was 11.2 dB.
- The overall mean air-bone gap for all subjects in the long-term group 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 people.
Methodology
This was a multi-institutional retrospective study analyzing postoperative air-bone gap in patients who underwent ossicular chain reconstruction using glass ionomer cement.
Potential Biases
There may be bias due to the noncontrolled design and the small number of participants.
Limitations
The study was retrospective and had a small sample size, which limits the power of the statistical analysis.
Participant Demographics
The average age of participants was 63 years, with 5 females and 10 males in the short-term group.
