Maksiller Sinüs Septa Varyasyonlarının Üç Boyutlu OlarakDeğerlendirilmesi: Retrospektif Çalışma

Amaç: Bu çalışmanın amacı; maksiller sinüs cerrahisiöncesinde konik ışınlı bilgisayarlı tomografi (KIBT) kullanılarakmaksiller sinüs septasının görülme sıklığı, lokalizasyonu veyönünü değerlendirmek ve bu varyasyonların yaş, cinsiyet vedental durumla olan ilişkisini incelemektir. Gereç ve Yöntemler: Çalışma grubu, Alanya Ağız ve DişSağlığı Merkezi arşivinin retrospektif olarak incelenmesisonucu elde edilen 290 hastanın (580 maksiller sinüs) KIBTgörüntüsünden oluşmuştur. Maksiller sinüs septa sayıları,KIBT görüntülerinin aksiyel kesitlerinde belirlenirken;lokalizasyon, yön ve morfolojileri hem aksiyel hem de sagittalkesitlerde belirlenmiştir. Yaş, cinsiyet ve dental durumun septavarlığı üzerine etkisi istatistiksel olarak analiz edilmiştir(p=0.05). Bulgular: Hastaların % 34.4’ünde en az bir septumgörülürken, kadın ve erkek hastalar arasında anlamlı birfarklılık görülmemiştir (p˃0.05). Septumun görülmelokalizasyonu ve yönü sırasıyla; orta bölgede (% 43.7) vekoronal yönde (% 53.9) olarak belirlenmiştir. Septa varlığı ileyaş ve cinsiyet arasında anlamlı bir ilişki gözlenmezken(p˃0.05), dental durum arasında anlamlı bir ilişki görülmüştür(p˂0.05). Septa yönü ve lokalizasyonu ile diğer parametrelerarasında da istatistiksel olarak anlamlı ilişki görülmemiştir(p˃0.05). Sonuç: Bulunan yüksek oranlar, maksiller sinüs septavaryasyonlarının diagnozunda KIBT’nin öneminigöstermektedir. Bu nedenle; maksiller arka bölgedeki cerrahimüdahalelerin başarısını arttırmak ve olası komplikasyonlarıönlemek için bölgenin KIBT ile değerlendirilmesi son dereceönemlidir.

Three Dimensional Evaluation of Maxillary Sinus SeptaVariations: Retrospective Study

Background: The purpose of this study to evaluate the frequency,localization and direction of the maxillary sinus septa and toexamine the relationship between these variations with age,gender and dental condition, using cone-beam computedtomography (CBCT) prior to maxillary sinus surgery. Methods: 290 CBCT images (Planmeca Romexis, 3D MidPlanmeca Oy, Helsinki, Finland) (580 maxillary sinüs) were chosenfrom the archive of Alanya Oral and Dental Health Center. Thenumber of maxillary sinüs septa was determined on axial sectionsof CBCT images. Their locations and orientations were determinedon both the axial and sagittal sections and their heights weredetermined only on the sagittal sections. The influence of the age,gender and dental status on the presence of septa was statisticallyanalysed (p=0.05). Results: While at least one septum was observed in 34.4% of thepatients, there was no significant difference between male andfemale patients (p˃0.05). The localization and direction of theseptum, respectively; in the central region (43.7%) and in thecoronal direction (53.9%). While there was no significantrelationship between the presence of septa and age and gender(p˃0.05), a significant relationship was observed between thedental condition (p˂0.05). There was no statistically significantrelationship between septa direction and localization and otherparameters (p˃0.05). Conclusion: These high rates of findings support the importanceof CBCT in the diagnosis of the variations of the maxillary sinüssepta. Therefore, it is important to evaluate CBCT images of therelevant region to increase the success of surgical interventions inthe maxillary posterior region and to eliminate possiblecomplications.
