ABSTRACT
Objective: Today, the preferred surgical technique in the
treatment of otosclerosis is stapedotomy. While many techniques are
used to create a small window at the footplate of stapes, there is no consensus
on the best technique. Our study aims to investigate the effect of
microdrill and manual perforator on bone conduction hearing thresholds.
Material and Methods: The patients who underwent stapedotomy
in our clinic were compared retrospectively dividing into 2 groups
as those with a manual perforator (Group I) and a microdrill (Group
II). The difference between the bone conduction thresholds at 500 Hz,
1000 Hz, 2000 Hz, 4000 Hz, and 8000 Hz from the preoperative and
postoperative pure tone audiometry tests were recorded, and the 2 groups
were compared for each frequency separately. Results: There were
34 in Group I and 18 patients in Group II. There was no statistically
significant difference between the groups in terms of gender, age, demographic
data and preoperative bone conduction hearing thresholds.
The groups were compared separately for each frequency in terms of
the mean difference between preoperative and postoperative bone conduction
thresholds, and no statistically significant difference was found
between the groups at any frequency. Conclusion: The data obtained
from our study shows that both the manual perforator and the microdrill
are safe methods that can be used in the sole perforation of the stapedotomy
operation. We believe that more studies are needed to
compare the differences between the 2 techniques.

ÖZET
Amaç: Günümüzde otosklerozun cerrahi tedavisinde tercih
edilen cerrahi teknik stapedotomidir. Stapes tabanında küçük bir
pencere oluşturmak için kullanılan birçok teknik bulunmakla birlikte,
en iyi teknik hakkında bir görüş birliği henüz yoktur. Çalışmamızın
amacı, mikrodrill ve manuel perforatörün kemik yolu işitme eşikleri
üzerine etkisini araştırmaktır. Gereç ve Yöntemler: Kliniğimizde
stapedotomi yapılan hastaların dosyaları retrospektif olarak incelendi.
Hastalar, taban perforasyonu manuel perforatör ile yapılanlar (Grup I)
ile mikrodrill ile yapılanlar (Grup II) olarak 2 gruba ayrıldı. Hastaların
preoperatif ve postoperatif saf ses odyometri testlerinden 500 Hz, 1000
Hz, 2000 Hz, 4000 Hz ve 8000 Hz’deki kemik yolu eşikleri ve aradaki
fark hesaplanarak kayıt altına alındı ve 2 grup her frekans için ayrı ayrı
karşılaştırıldı. Bulgular: Grup I’de 34 hasta, Grup II’de ise 18 hasta
vardı. Gruplar arasında cinsiyet, yaş, demografik veriler ve preoperatif
kemik yolu işitme eşikleri açısından istatistiksel olarak anlamlı bir fark
tespit edilmedi. Grupların her frekans için ayrı olarak preoperatif ve
postoperatif kemik yolu eşikleri arasındaki ortalama fark karşılaştırıldı
ve hiçbir frekansta gruplar arasında istatistiksel olarak anlamlı fark
tespit edilmedi. Sonuç: Çalışmamızdan elde edilen veriler, stapedotomi
operasyonunda hem manuel perforatör hem de mikrodrillin taban
perforasyonunda kullanılabilecek güvenli yöntemler olduğunu göstermektedir.
İki teknik arasındaki farkları karşılaştırmak için daha fazla
çalışmaya ihtiyaç olduğuna inanıyoruz.
