ABSTRACT
 Objective: This study investigated the frequency of anatomic variations in the sinonasal region with septal deviation and the relationship of these anatomic variations with the developmental direction of the maxilla in cone-beam computed tomography images. Material and Methods: Forty-eight patients who underwent orthognathic surgery were included in this study. These patients were divided into 3 groups: normal maxilla (n=16), prognathic maxilla (n=16), and retrognathic maxilla (n=16) by determining the position of the maxillae in relation to the skull base on lateral cephalometric radiographs. The anatomic variations of the sinonasal region and the presence of maxillary sinus ostium (MSO) obstruction were studied in all groups. The relationship between the anatomical variations and the different developmental aspects of the maxilla was analyzed. Results: The most common anatomical changes in all patients were: hypertrophy of the inferior turbinate (68.8%), deviation of the nasal septum (66.7%), and concha bullosa (62.5%). No statistically significant difference was found between the groups with different skeletal deformities based on the position of the maxilla in relation to the skull base (p>0.05). While there was a statistically significant difference between gender distribution and hypertrophy of the middle concha (p=0.016), no statistically significant difference was found between other anatomical variations and gender distribution (p>0.05). Conclusion: In conclusion, in this study, we investigated the relationship between the anatomical variations of the sinonasal region and the direction of maxillary growth. There was no significant relationship between the above anatomical variations and MSO obstruction between the groups.

Keywords: Anatomic variation; maxillary sinus; nasal cavity; cone-beam computed tomography
ÖZET
 Amaç: Bu çalışmada, sinonazal bölgedeki anatomik varyasyonların septal deviasyon ile birlikte görülme sıklığı ve bu anatomik varyasyonların lateral sefalometrik radyograflarda belirlenen maksiller gelişim yönü ile ilişkisi konik ışınlı bilgisayarlı tomografi görüntülerinde araştırılmıştır. Gereç ve Yöntemler: Ortognatik cerrahi operasyonu gereken 48 hasta çalışmaya dâhil edildi. Bu hastalar, lateral sefalometrik radyograflarda maksillaların kafatası tabanına göre konumları belirlenerek normal maksilla (n=16), prognatik maksilla (n=16) ve retrognatik maksilla (n=16) olmak üzere 3 grupta sınıflandırıldı. Sinonazal bölgenin anatomik varyasyonları ve maksiller sinüs ostiyumunun tıkanıklığının varlığı tüm gruplarda araştırıldı. Anatomik varyasyonlar ile maksillanın farklı gelişimsel yönleri arasındaki ilişki analiz edildi. Bulgular: Tüm hastalarda en sık görülen anatomik varyasyonlar; alt konka hipertrofisi (%68,8), nazal septum sapması (%66,7) ve konka büllozaydı (%62,5). Kafatası tabanına göre maksillanın pozisyonuna bağlı olarak farklı iskeletsel deformitesi olan gruplar arasında istatistiksel olarak anlamlı bir fark bulunmadı (p>0,05). Cinsiyet dağılımı ile orta konka hipertrofisi arasında istatistiksel olarak anlamlı fark bulunurken (p=0,016), diğer anatomik varyasyonlar ile cinsiyet dağılımı arasında istatistiksel olarak anlamlı bir fark bulunmadı (p>0,05). Sonuç: Sonuç olarak bu çalışmada, sinonazal bölgenin anatomik varyasyonlarının maksiller büyüme yönü ile arasındaki ilişkiyi araştırdık. Gruplar arasında yukarıdaki anatomik varyasyonlar ve maksiller sinüs ostiyum obstrüksiyonu arasında anlamlı bir ilişki bulunmadı.

Anahtar Kelimeler: Anatomik varyasyon; maksiller sinüs; nazal kavite; konik ışınlı bilgisayarlı tomografi
