Comparison of the Ionomeric Bone Cement and incus Interposition in Reconstruction of Ossicular Chain

Öz

Objective: In this study, we aimed to compare the success of glass ionomer cement application (GIC) and incus interpositioning technique in terms of hearing results and graft take rates.

Methods: This retrospective study performed on 53 patients who had surgery for chronic otitis media. All patients had an incus long process defect and a normal stapes superstructure. Ossicular reconstruction was performed using incus interposition technique in 31 patients (group 1), while GIC was performed in other 22 patients (group 2). The age, sex, success rate of graft take and hearing results were compared between the groups.

Results: In both groups, there was a statistical significant improvement in terms of the mean air conductance threshold and decrease in the mean air-bone gap (ABG) (p=0.001; p<0.001) The comparison of the mean ABG changes in terms of success,  between incus interposition and GIC groups showed no statistically significant difference (p>0,05).

Conclusion: Both GIC application and incus interpositioning technique are effective methods in reconstructing incus long bone defects and they are not superior to each other.

Kemikçik Zincir Onarımında İyonomerik Kemik Çimentosu ve İnkus İnterpozisyonun Karşılaştırılması

Öz

 Amaç:Çalışmamızda inkus uzun kolu defektlerinin onarımında iyonomerik kemik çimentosu  (İKÇ) ve inkus interpozisyon (İİ) kullanılan hastaları, işitme sonuçları ve greft başarısı açısından karşılaştırmayı amaçladık.

Yöntem: Bu retrospektif çalışmaya kemik zincir de stapes suprastrukturu normal olup inkus uzun kolu defektif olan ve kemikçik zincir rekonstrüksiyonu yapılan 53 hasta dahil edildi. Hastalar kemikçik zincir onarım tekniğine göre, İİ kullanılanlar (Grup 1) ve İKÇ kullanılanlar (Grup 2) olarak iki gruba ayrıldı. Gruplar yaş, cinsiyet, greft başarı oranı, hava saf ses eşikleri değerleri ve hava-kemik aralığı (HKA) açısından karşılaştırıldı.

Bulgular: Her iki grup da operasyon sonrası hava saf ses eşiklerindeki ve preoperatif döneme göre postoperatif HKA değerlerindeki düzelme istatiksel olarak ileri derecede anlamlıydı (p=0.001; p<0,01). Gruplar arasında HKA değerlerinin fonksiyonel olarak başarılı olarak kabul edilmesine göre istatistiksel olarak anlamlı farklılık saptanmamıştır (p>0,05).

Sonuç:İnkus uzun kolu defekti olan hastalarda kemikçik zincir onarımı amacıyla kullanılan İKÇ ve İİ etkili yöntemlerdir ve birbiri üzerine belirgin bir üstünlükleri yoktur.
