Abstract

Objectives: This study aims to evaluate our ossiculoplasty results using hydroxyapatite bone cement. Patients and Methods: Data of 29 patients 16 males, 13 females; mean age 28 years; range 17 to 57 years who were performed ossiculoplasty using hydroxyapatite bone cement in İzmir Katip Çelebi University Atatürk Training and Research Hospital Department of Otorhinolaryngology between January 2010 and December 2013 were retrospectively evaluated. Of the 29 operated patients, bone cement was administered in 23 patients during tympanoplasty, in two patients during open technique tympanomastoidectomy, and in four patients during exploratory tympanotomy. Hydroxyapatite bone cement was only used to repair defects between incus and stapes no longer than one third of incus long arm length. Mean follow-up time was 6.5 months range 2-32 months . Results: Success of ossiculoplasty was evaluated by Belfast 15/30 dB rule of thumb. Preoperative air-bone gap was 45.1 dB range 35-55 and postoperative air-bone gap was 17.7 dB range 6-40 . Air-bone gap was below 10 dB in six patients, between 10-20 dB in 14 patients, between 20-30 dB in seven patients, and between 30-40 dB in two patients. Conclusion: Ossiculoplasty using hydroxyapatite bone cement is a safe and effective method for the repair of particularly small incus long arm defects.

Abstract

Amaç: Bu çalışmada hidroksiapatit kemik çimento kullanılarak yapılan ossiküloplasti sonuçlarımız değerlendirildi.Hastalar ve Yöntemler: İzmir Katip Çelebi Üniversitesi Atatürk Eğitim ve Araştırma Hastanesi Kulak Burun Boğaz Bölümü’nde Ocak 2010 - Aralık 2013 tarihleri arasında hidroksiapatit kemik çimento kullanılarak ossiküloplasti yapılan 29 hastanın 16 erkek, 13 kadın; ort. yaş 28 yıl; dağılım 17-57 yıl verileri retrospektif olarak değerlendirildi. Ameliyat edilen 29 hastanın 23’üne timpanoplasti, ikisine açık teknik timpanomastoidektomi, dördüne ise eksploratris timpanotomi sırasında kemik çimento uygulandı. Hidroksiapatit kemik çimento sadece inkus ile stapes arasındaki inkus uzun kol uzunluğunun üçte birinden uzun olmayan defektleri onarmak için kullanıldı. Ortalama takip süresi 6.5 ay dağılım 2-32 ay idi.Bulgular: Ossiküloplastinin başarısı Belfast 15/30 dB başparmak kuralı ile değerlendirildi. Ameliyat öncesi ortalama hava-kemik yolu aralığı 45.1 dB , ameliyat sonrası ortalama hava-kemik yolu aralığı ise 17.7 dB idi. Hava-kemik yolu aralığı altı hastada 10 dB’nin altında, 14 hastada 10-20 dB aralığında, yedi hastada 20-30 dB aralığında ve iki hastada 30-40 dB aralığında idi.Sonuç: Hidroksiapatit kemik çimento kullanılan ossiküloplasti özellikle küçük inkus uzun kolu defektlerinin onarımında güvenilir ve etkin bir yöntemdir
