Maksiller Sinüs Patolojileri ile Ostium Boyutları Arasındaki İlişkinin Araştırılması: Bir Retrospektif Konik Işınlı Bilgisayarlı Tomografi Çalışması

Amaç: Maksiller sinüs ostiumu sinüs medial duvarının en üst kısmıdır ve bundan dolayı yerleşimi drenaj açısından zayıftır. Bununla birlikte nazal fossaya direk açılmayıp, dar etmoidal infindibuluma açılır ki drenajı kesintiye uğratan enflamasyon kronik maksiller sinüzit gelişiminde rol oynar. Bu çalışmanın amacı maksiller sinüs patolojilerini (MSP) ve bu patolojilerin maksiller sinüs ostium boyutlarıyla olası ilişkilerini araştırmaktır.Gereç ve Yöntemler: 139 hastaya ait (52 erkek ve 87 kadın) Konik Işınlı Bilgisayarlı Tomografi (KIBT) görüntüleri ostium boyutları ve retansiyon kisti ile mukozal kalınlaşmayı içeren MSP varlığı açısından retrospektif olarak değerlendirildi. Bağımsız Örneklem T-Testi ve Pearson Ki-Kare testi istatistiksel analiz aşamasında kullanıldı.Bulgular: MSP olan ve olmayan hastalar arasında ostium genişliği açısından istatistiksel bir farklılık görülmedi (p=0.13). MSP olan hastalarda ortalama ostium genişliği 2.08 mm iken, MSP olmayanlarda ortalama genişlik 2.14 mm olarak ölçüldü. İncelenen tüm hastalarda sağ ve sol ostium genişlik ortalamaları sırasıyla 1.97 mm (Aralık 0.67-4.25) ve 2.26 mm (Aralık 0.67-5.25) olarak bulundu. Cinsiyete göre ostium genişliği açısından istatistiksel farklılık görülmedi (p≥0.05). Tüm hastalar arasında %18.7 (n=26) hastada MSP izlenirken, bunlardan 10 tanesi çift taraflı, 16 tanesi ise tek taraflıdır. Sonuç: MSP, KIBT araştırmalarında en yaygın bulgu olup, bu çalışmanın sonuçları göstermektedir ki MSP ile ostium genişliği ilişkili bulunmamıştır.

EVALUATION OF RELATIONSHIP BETWEEN MAXILLARY SINUS PATHOLOGIES AND OSTIUM DIMENSION: A RETROSPECTIVE CONE BEAM COMPUTED TOMOGRAPHY STUDY

Objective: Maxillary sinus ostium is the top section of the medial wall the and is hence poorly placed from the point of view of free drainage; it opens into the narrow ethmoidal infundibulum, inflammation of which can further break drainage, so this may cause in the development of chronic maxillary sinusitis. This study aims to evaluate maxillary sinus pathologies (MSP) and their possible relation with maxillary sinus ostium dimensions.Material and Methods: Cone Beam Computed Tomography (CBCT) scans which belong to 139 patients (52 male and 87 female) were retrospectively evaluated with regard to ostium dimensions and the presence of MSP including retention cyst and mucosal thickening. Independent Samples t-test and Pearson Chi-Square were used to for statistical analysis.Results: No statistically significant difference was observed between patients with and without MSP in terms of ostium width (p=0.13). While the mean ostium width was 2.08 mm in the patient with MSP it was measured as 2.14 mm in patients without MSP. For all patients examined, right and left ostiums mean widths were 1.97 mm (Range 0.67-4.25) and 2.26 mm (Range 0.67-5.25), respectively. No significant difference was observed in ostium width according to gender (p≥0.05). Among all patients, 18.7% (n=26) had MSP; of these 10 were bilateral and 16 were unilateral. Conclusion: MSP is the common finding in CBCT examinations and the results of this study showed that MSP does not seem to be associated with the ostium width.
