Abstract

Objectives: This study aims to investigate whether the existence of any Carhart notch on audiogram in otosclerosis surgery has any effect on the success of operation. Patients and Methods: We examined the pre- and postoperative audiograms of 40 patients (11 males, 29 females; mean age 38.7 years; range, 13 to 62 years) included in the study. We divided the patients into two groups as those with or without Carhart notch. We calculated the hearing averages at 500, 1000, 2000, and 4000 Hz on the audiogram peri- and postoperatively. We investigated whether there was any significant difference in postoperative hearing gain between those with or without Carhart notch. Results: Of the patients, 24 did not have any Carhart notch (57.5%), while 16 had a Carhart notch (40%). We did not observe any statistically significant difference between airway threshold averages of Carhart (-) and Carhart (+) groups pre- or postoperatively at 1000, 2000 or 4000 Hz. Increase in hearing gain at postoperative 500, 1000, 2000, and 4000 Hz was statistically significant in both groups. Conclusion: Otosclerosis surgery is an application that increases hearing gain. The presence of any Carhart notch on audiogram does not seem to affect surgical success; however, studies with wider series are needed to illuminate this.

Özet

Amaç: Bu çalışmada otoskleroz cerrahisinde odyogramdaCarhart çentiği varlığının ameliyat başarısına etkisi olupolmadığı araştırıldı. Hastalar ve Yöntemler: Çalışmaya alınan 40 hastanın(11 erkek, 29 kadın; ort. yaş 38.7 yıl; dağılım, 13-62 yıl)ameliyat öncesi ve sonrası odyogramları incelendi. HastalarCarhart çentiği olanlar ve olmayanlar şeklinde iki grubaayrıldı. Odyogramda 500, 1000, 2000 ve 4000 Hz’dekiişitme ortalamaları perioperatif ve ameliyat sonrası olarakhesaplandı. Carhart çentiği olanlarla olmayanların ameliyatsonrası işitme kazançları arasında anlamlı bir farklılık olupolmadığı araştırıldı. Bulgular: Hastaların 24’ünde Carhart çentiği yokken (%57.5)16’sında Carhart çentiği vardı (%40). Carhart (-) ve Carhart(+) gruplarının ameliyat öncesi ve sonrası 1000, 2000 ve4000 Hz’deki hava yolu eşik ortalamaları arasında istatistikselolarak anlamlı farklılık gözlemlenmedi. Her iki grubunameliyat sonrası 500, 1000, 2000 ve 4000 Hz’deki işitmekazancındaki artış istatistiksel olarak anlamlı idi. Sonuç: Otoskleroz cerrahisi işitme kazancını artıran biruygulamadır. Odyogramda Carhart çentiği varlığı cerrahibaşarıyı etkilemiyor gibi görünmektedir, ancak bununaydınlatılması için daha geniş serili çalışmalara ihtiyaç vardır.
