Abstract

Introduction: Retrodiscal tissue undergoes remodelling and a decrease in vascularity occurs when the temporomandibular joint disc is displaced. During this process deformities may be seen at the disc which is attached to the retrodiscal tissues. Purpose: The purpose of this study was to com¬pare the disc deformities among the disc displacement types. Patients and Methods: Two hundred eighteen TMJs of 109 patients ( 92 female and 17 male) were studied using magnetic resonance imaging examination. Results: Of 218 TMJ discs, 84 had no disc displacement, and only %8,3 of these discs had deformities. Of 134 TMJ discs which had disc displacement, %69,4 had disc deformities. The difference between non disc displacement and disc displacement groups was statistically signi¬ficant (p

Özet

Giriş.Temporomandibular eklem diskinin yer değiştirdiği redüksiyonlu ve redüksiyonsuz disk deplasmanı olgularında, retrodiskal doku kondil ve temporomandibular kemik arasında kalır, vaskülarizasyonu azalır ve yeniden yapılanma süreci başlar. Bu süreç içerisinde retrodiskal dokuların bağlı olduğu diskte de deformasyonlar gözlenir. Amaç: Bu çalışmanın amacı redüksiyonlu ve redüksiyonsuz disk deplasmanı olgularında disk deformas-yonlarının sınıflandırılması ve karşılaştırılmasıdır. Birey ve Yöntem: Çalışmada 109 hastaya ait 218 eklemin manyetik rezonans görüntüleri değerlendirilmiştir. Bulgular. Disk deplasmanı olmayan 84 eklemin 7'sinde (%8,3) disk deformasyonu görülürken, redük¬siyonlu veya redüksiyonsuz disk deplasmanı olan 134 eklemin 93'ünde (%69,4) disk deformasyonu gözlenmiş ve istatistiksel olarak anlamlı bulunmuştur (p
