Abstract

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.

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

Abstract

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.
