ABSTRAK
Tujuan: Untuk mengetahui perbedaan ambang dengar pre dan pasca operasi timpanoplasti pada pasien otitis media supuratif kronis.
Metode: Pasien yang menjalani timpanoplasti (n=21) dilakukan observasi secara prospektif. Dilakukan penilaian ambang dengar dengan menggunakan audiometri
nada murni pre dan 12 minggu pasca timpanoplasti (AC, BC dan perubahan
ambang dengar) pada frekuensi 500Hz, 1kHz, 2kHz, dan 4kHz.
Hasil: AC pre dan pasca timpanoplasti menunjukan perbedaan bermakna disemua frekuensi sedangkan BC pre dan pasca timpanoplasti hanya menunjukkan
perbedaan bermakna difrekuensi 2kHz dan 4kHz. Selain itu dijumpai perbedaan
rerata ambang dengar pre dan pasca timpanoplasti pada pasien otitis media
supuratif kronis.
Kesimpulan: Setelah timpanoplasti dijumpai perbaikan AC disemua frekuensi dengan rerata perbaikan ambang dengar 0-5 dB, meskipun demikian diperlukan
evaluasi lebih lanjut mengenai perbaikan ambang dengar pasca timpanoplasti pada
masing-masing tipe timpanoplasti.

ABSTRACT
Objective: The objective of the research was to find out the disparity in hearing
threshold in pre and post tympanoplasty surgery in patients with chronic suppurative otitis media.
Material and Method: Prospective observation was performed for patients who
underwent tympanoplasty (n=21). Hearing threshold was evaluated by using pure tone eudiometry in the pre and 12 weeks of post tympanoplasty surgery (AC, BC, and the change in hearing threshold) in the frequency of 500Hz, IKHz, 2kHz, and 4kHz.
Results: AC in the pre and post tympanoplasty indicated significant disparity in
the frequency of 2kHz and 4kHz. Besides that, there was the disparity in the mean value of hearing threshold in the pre and post tympanoplasty in patients with CSOM.
Conclusion: In the post tympanoplasty surgery, it was found that there was the
improvement in AC in all frequencies with the mean value of improvement of hearing threshold of 0-5 dB. Nevertheless, further evaluation on the improvement of hearing threshold in the post tympanoplasty surgery in each type of tympanoplasty would be needed.
