Abstract

Objectives: To investigate the effect of external ear canal wall on functional outcomes of ossicular reconstruction procedures withtitanium total ossicular replacement prosthesis (TORP).Methods: Patients who underwent middle ear surgery and ossicular reconstruction with TORP in a tertiary referral center between 2009-2014 were retrospectively searched in two groups; Canal Wall Up (CWU) + TORP and Canal Wall Down (CWD) + TORP. Functionalresults were evaluated.Results: A total number of 89 cases were evaluated. CWU group included 25, CWD group included 36 patients who met inclusioncriteria. In the CWU group, the mean pre-operative pure tone average (PTA) value was 58.1±11.2 dB; postoperative PTA was 44.1±17.9 dB,the mean increase was 13.9±14.3 dB. In the CWD group, the mean preoperative PTA was 56.6 ±15.3 dB, postoperative PTA was 50.6±21.3dB, the mean increase was 6.0±15.6 dB. The mean air-bone gap (ABG) closure value was 14.4±11.5 dB in the CWU group and 6.4±10.5 dBin the CWD group. There was a significant difference in terms of PTA increase and ABG closure values between the two groups.Conclusions: The external ear canal wall has a positive effect on postoperative hearing when an ossiculoplasty with Titanium TORP isperformed. The removal of ECW leads to a hearing loss of about 9dB in PTA levels and 8dB in ABG closure values in these cases.

Özet

Amaç: Mevcut çalışmamızda, titanium total ossikuler replasman protezi (TORP) kullanılarak ossikuloplasti yapılan olgularda dış kulak yolu (DKY) arka duvarının korunmasının fonksiyonel sonuçlara etkisini belirlemek amaçlandı. Yöntemler: Kurumumuzda 2009-2014 yılları arasında kronik otitis media (KOM) nedeniyle orta kulak cerrahisi ve TORP kullanılarak ossikuler rekonstruksiyon operasyonu geçiren hastalar iki grup altında incelenerek fonksiyonel sonuçlar karşılaştırıldı: Canal Wall Up (CWU) + TORP ve Canal Wall Down (CWD) + TORP. Bulgular: Toplamda 89 olgunun verileri incelendi. Dahil olma kriterlerine uyan 61 hasta çalışmaya alındı: CWU grupta 25, CWD grupta 36 hastanın verileri analiz edildi. CWU grupta ortalama pre-operatif saf ses ortalaması (SSO) 58.1±11.2 dB; post-operatif SSO 44.1±17.9 dB, ortalama düzelme 13.9±14.3 dB olarak saptanırken, CWD grupta pre-operatif SSO 56.6±15.3 dB, post-operatif SSO 50.6±21.3 dB, ortalama düzelme 6.0±15.6 dB olarak saptandı. Ortalama hava-kemik aralığı (HKA) kapanma değerleri ise CWU grupta 14.4±11.5 dB, CWD grupta 6.4±10.5 dB olarak saptandı. SSO düzelme ve HKA kapanma değerleri açısından iki grup arasında istatistiksel olarak anlamlı fark saptandı. Sonuç: Titanyum TORP kullanılarak yapılan ossikuloplasti prosedürlerinde, DKY arka duvarının korunmasının fonksiyonel sonuçlara anlamlı etkisi mevcuttur. Bu olgularda DKY arka duvarının kaldırılması, SSO değerlerinde yaklaşık 9dB, HKA kapanma değerlerinde ise yaklaşık 8dB kayıba neden olacaktır.
