Hearing outcomes after suppurative chronic otitis media surgery

Abstract

Objectives: This study aims to compare the hearing outcomes after canal wall up mastoidectomy CWUM and canal wall down mastoidectomy CWDM . Patients and Methods: Ninety-two patients 74 males, 18 females; mean age 30.1 years; range 9 to 67 years who were diagnosed with chronic suppurative otitis media CSOM between January 2009 and May 2011 were enrolled in this retrospective study. Based on hospital data, patients were separated into two groups as having mucosal or squamous disease. Patients were also categorized into two groups based on the type of mastoidectomy: CWUM n=51 and CWDM n=41 . Hearing results between the groups were evaluated using the air-bone gap ABG recorded by audiogram before surgery and at three months after ossiculoplasty. Relationship between obtained hearing results and performed ossiculoplasty techniques were also discussed. Results: We were able to perform ossiculoplasty in 42.3% n=39 of patients diagnosed with CSOM. Presurgical ABG in CWUM and CWDM groups were 35.38±10.82 dB and 37.92±5.80 dB, respectively. Postsurgical ABG value was ≤20 dB in 27% of CWUM patients and 7.7% of CWDM patients. Mean hearing gain of patients with active squamous disease was 3.8 dB in CWUM group and 11.9 dB in CWDM group p<0.5 . Conclusion: The pathology affecting the middle ear had influence on the hearing results of the two groups. Canal wall down mastoidectomy may be a beneficial procedure to improve hearing in patients with CSOM.

Süpüratif kronik otitis media cerrahisi sonrası işitme sonuçları

Abstract

Amaç: Bu çalışmada açık kavite teknik AKT ve kapalı kavite teknik KKT ile mastoidektomi sonrası işitme sonuçları karşılaştırıldı.Hastalar ve Yöntemler: Ocak 2009 - Mayıs 2011 tarihleri arasında kliniğimizde kronik süpüratif otitis media KSOM tanısı konulan 92 hasta 74 erkek, 18 kadın; ort yaş 30.1 yıl; dağılım 9-67 yıl bu retrospektif çalışmaya alındı. Hastalar hastane verilerine dayanılarak mukozal veya skuamöz hastalıklı olarak iki gruba ayrıldı. Hastalar mastoidektomi tipine göre de iki grup olarak sınıflandırıldı: KTM n=51 ve ATM n=41 . İki grup arasındaki işitme sonuçları cerrahi öncesi ve ossiküloplastiden üç ay sonra odyogram ile kaydedilen hava-kemik aralığı HKA kullanılarak değerlendirildi. Elde edilen işitme sonuçları ile uygulanan ossiküloplasti teknikleri arasındaki ilişki de tartışıldı.Bulgular: Ossiküloplasti KSOM tanısı konulan hastaların %42.3’üne n=39 yapılabildi. Kapalı teknik mastoidektomi ve ATM gruplarında cerrahi öncesi HKA sırasıyla 35.38±10.82 dB ve 37.92±5.80 dB idi. Kapalı teknik mastoidektomi hastalarının %27’sinde ve ATM hastalarının %7.7’sinde cerrahi sonrası HKA değeri ≤20 dB idi. Aktif skuamöz hastalığı olan hastaların ortalama işitme kazancı KTM grubunda 3.8 dB, ATM grubunda 11.9 dB idi p
