Hypothesis
To evaluate the long-term surgical outcomes in patients who have undergone canal-wall-down operation with mastoid and epitympanic obliteration using autologous cortical bone chips.
Conclusion
The configuration of the cavity tends to change over time, but the obliteration material remains stable and significant cavitation rarely occurs.
Supporting Evidence
- The mean volume of the operated ear canal was significantly larger than the contralateral ear canal.
- Most patients reported no need for regular debridements after surgery.
- No residual cholesteatomas were found in the study population.
Takeaway
Doctors used bone from patients' own bodies to fill in holes in their ears after surgery, and most patients did well over many years.
Methodology
Retrospective evaluation of 70 patients who underwent surgery for cholesteatoma between 1986 and 1991, with assessments including otomicroscopy and tympanometry.
Limitations
The study was retrospective and only included patients who consented to participate.
Participant Demographics
48 males and 22 females, mean age at operation was 40 years.
Statistical Information
P-Value
p < 0.0001 for the volume of the operated ear canal compared to the contralateral ear canal.
