TÜRK TOPLUMUNDAKİ MAKSİLLER SİNÜS SEPTA VARYASYONLARININ ÜÇ BOYUTLU OLARAK DEĞERLENDİRİLMESİ

Amaç: Bu çalışmanın amacı; maksiller sinüs cerrahisi öncesinde konik ışınlı bilgisayarlı tomografi (KIBT) kullanılarak Türk toplumundaki maksiller sinüs septasının görülme sıklığı, lokalizasyonu ve yönünü değerlendirmek ve bu varyasyonların yaş, cinsiyet ve dental durumla olan ilişkisini incelemektir. Gereç ve Yöntemler: Çalışma grubu, Alanya Ağız ve Diş Sağlığı Merkezi arşivinin retrospektif olarak incelenmesi sonucu elde edilen 290 hastanın (580 maksiller sinüs) KIBT görüntüsünden oluşmuştur. Maksiller sinüs septa sayıları, KIBT görüntülerinin aksiyel kesitlerinde belirlenirken; lokalizasyon, yön ve morfolojileri hem aksiyel hem de sagittal kesitlerde belirlenmiştir. Yaş, cinsiyet ve dental durumun septa varlığı üzerine etkisi istatistiksel olarak analiz edilmiştir (p=0.05). Bulgular: Hastaların %34.4’ünde en az bir septum görülürken, kadın ve erkek hastalar arasında anlamlı bir farklılık görülmemiştir (p˃0.05). Septumun görülme lokalizasyonu ve yönü sırasıyla; orta bölgede (%43.7) ve koronal yönde (%53.9) olarak belirlenmiştir. Septa varlığı ile yaş 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 parametreler arasında da istatistiksel olarak anlamlı ilişki görülmemiştir (p˃0.05). Sonuç: Bulunan yüksek oranlar, maksiller sinüs septa varyasyonlarının diagnozunda KIBT’nin önemini göstermektedir. Bu nedenle; maksiller arka bölgedeki cerrahi müdahalelerin başarısını arttırmak ve olası komplikasyonları önlemek için bölgenin KIBT ile değerlendirilmesi son derece önemlidir.

THREE DIMENSIONAL EVALUATION OF MAXILLARY SINUS SEPTA VARIATIONS IN A TURKISH POPULATION

Background: The purpose of this study to evaluate the frequency, localization and direction of the maxillary sinus septa in a Turkish population and to examine the relationship between these variations with age, gender and dental condition, using cone-beam computed tomography (CBCT) prior to maxillary sinus surgery. Methods: 290 CBCT images (Planmeca Romexis, 3D Mid Planmeca Oy, Helsinki, Finland) (580 maxillary sinüs) were chosen from the archive of Alanya Oral and Dental Health Center. The number of maxillary sinüs septa was determined on axial sections of CBCT images. Their locations and orientations were determined on both the axial and sagittal sections and their heights were determined only on the sagittal sections. The influence of the age, gender and dental status on the presence of septa was statistically analysed (p=0.05). Results: While at least one septum was observed in 34.4% of the patients, there was no significant difference between male and female patients (p˃0.05). The localization and direction of the septum, respectively; in the central region (43.7%) and in the coronal direction (53.9%). While there was no significant relationship between the presence of septa and age and gender (p˃0.05), a significant relationship was observed between the dental condition (p˂0.05). There was no statistically significant relationship between septa direction and localization and other parameters (p˃0.05). Conclusion: These high rates of findings support the importance of CBCT in the diagnosis of the variations of the maxillary sinüs septa. Therefore, it is important to evaluate CBCT images of the relevant region to increase the success of surgical interventions in the maxillary posterior region and to eliminate possible complications.
