Endoskopik modifiye kelebek timpanoplasti ile incudostapedial rekonstrüksiyon sonuçları

Amaç: Bu çalışmanın amacı, kemikçik zincir patolojilerini de içeren perforasyonlarda endoskopik kelebek timpanoplasti sonuçlarını değerlendirmektir. Gereç ve Yöntem: Çalışmada 29 hastada endoskopik modifiye kelebek timpanoplasti sonuçlarını değerlendirdik. Çalışmaya malleus manubriumunu içeren geniş timpanik membran perforasyonları olan ve kemikçik zincir patolojileri olanlar, endoskopik transkanal timpanoplasti ile ameliyat edilen hastalar dahil edildi. Bulgular: Timpanik membran kapanma oranı % 89.7 idi (n=26). Ameliyat öncesi ve sonrası dönemde ortalama hava iletimi sırasıyla 37.75 ± 5.20 dB ve 18.96 ± 6.52 dB idi. Ameliyat sonrası dönemdeki hava yolu saf ses ortalamalarındaki düşüş istatistiksel olarak anlamlı 18.79 ± 7.33 bulundu. Ameliyat öncesi ve sonrası hava-kemik aralığı sırasıyla 27,82 ± 4,74 dB ve 9,17 ± 4,89 dB olarak bulundu. Ameliyat öncesi ve sonrası karşılaştırıldığında hava kemik aralığındaki azalma 18,62 ± 7,11 olarak bulundu ve istatistiksel olarak anlamlı olarak değerlendirildi. Sonuç: Endoskopik modifiye kelebek timpanoplasti tekniği, incudostapedial eklem defektli büyük perforasyonlarda başarılı sonuçlar verebilen minimal invaziv bir tekniktir.

Outcome of incudostapedial reconstruction with endoscopic modified butterfly tympanoplasty

Purpose: The aim of this study was to evaluate the results of endoscopic butterfly tympanoplasty in perforations that involve the ossicular chain pathologies. Materials and Methods: We assessed the outcome of endoscopic modified butterfly tympanoplasty in 29 patients. The study included those with large tympanic membrane perforations covering the manubrium of malleus and has ossicular chain pathologies, operated via endoscopic transcanal tympanoplasty. Results: The tympanic membrane closure rate was 89.7% (26 of 29 ears). The mean air conduction in the pre- and postoperative period was 37.75±5.20 dB and 18.96±6.52 dB, respectively, with a statistically significant decrease of 18.79±7.33. The mean pre- and the postoperative air-bone gap was 27.82±4.74 dB and 9.17±4.89 dB, respectively, with a statistically significant decrease of 18.62±7.11 Conclusion: The endoscopic modified butterfly tympanoplasty technique is a minimally invasive technique that can provide successful results in large perforations with defective incudostapedial joint.
