Abstract

Aim: For a correct and adequate chronic otitis media surgery, it is necessary to correctly define the anatomical structures and to know their possible variations, otherwise, an increase in the complication rate is inevitable. This study aims to present the anatomical variations detected both in preoperative computerized tomography scanning and during operation, and complication rates encountered in 308 patients who underwent tympanomastoidectomy due to chronic otitis media in the light of current literature knowledge.
Materials and Methods: In this retrospective study, the files of 308 patients who underwent tympanomastoidectomy due to chronic otitis media in a tertiary clinic between September 2011 and July 2019 were scanned for encountered anatomical variations detected both in preoperative computerized tomography scanning and during operation and complications.
Results: There was Körner septum in 12 (3.8%) cases, dehiscence in the facial nerve tympanic segment in 12 (3.8%) cases, and lateral semicircular canal dehiscence (LSCD) in 4 (1.3%) cases. In 4 (1.3%) cases, it was observed that the dura was located downward and in 6 (1.9%) cases, the sigmoid vein was located anterosuperiorly.
Conclusion: Always being careful in terms of anatomical variations and possible complications during the operation will increase the success of the surgery. Knowing the anatomical variations and complications related to the temporal region is of great importance for clinicians dealing with ear surgery.

Kronik Otitis Media Cerrahisinde Anatomik Varyasyonlar; Tomografi ve Perioperatif Bulguların Karşılaştırılması

Abstract

Amaç: Doğru ve yeterli bir kronik otitis media cerrahisi için anatomik yapıların doğru tanımlanması ve olası varyasyonlarının bilinmesi gereklidir, aksi takdirde komplikasyon oranının artması kaçınılmazdır. Bu çalışmada hem preoperatif bilgisayarlı tomografi taramasında hem de operasyon sırasında saptanan anatomik varyasyonları ve kronik otitis media nedeniyle timpanomastoidektomi uygulanan 308 hastada karşılaşılan komplikasyon oranlarını güncel literatür bilgileri ışığında sunmayı amaçladık.
Gereç ve Yöntemler: Bu retrospektif çalışmada, Eylül 2011-Temmuz 2019 tarihleri arasında üçüncü basamak bir klinikte kronik otitis media nedeniyle timpanomastoidektomi uygulanan 308 hastanın dosyaları, karşılaşılan anatomik varyasyonlar açısından hem ameliyat öncesi bilgisayarlı tomografi taramasında hem de ameliyat sırasında not edilen bulgular ve komplikasyonlar açısından tarandı. .
Bulgular: 12 (% 3.8) olguda Körner septum, 12 (% 3.8) olguda timpanik segmentte fasiyal dehissans ve 4 (% 1.3) olguda lateral semisirküler kanal dehissansı (LSCD) vardı. 4 (% 1.3) olguda duranın aşağı, 6 (% 1.9) olguda sigmoid venin anterosuperior yerleşimli olduğu görüldü.
Sonuç: Operasyon sırasında anatomik varyasyonlar ve olası komplikasyonlar açısından her zaman dikkatli olmak ameliyatın başarısını artıracaktır. Temporal bölgeyle ilgili anatomik varyasyonların ve komplikasyonların bilinmesi kulak cerrahisi ile uğraşan klinisyenler için büyük önem taşımaktadır.
