Amaç: Bu çalışmanın amacı; çocuklarda foramen infraorbitalenin [infraorbital foramen (IOF)], konumu, şekli ve varyasyonlarının incelenerek bu bölgede cerrahi işlem ve enjeksiyon uygulayan hekimlere katkı sağlamaktır. Gereç ve Yöntemler: Çalışmaya, 60 çocuk hasta dâhil edildi. Sağ ve sol bölgelerde IOF tespit edildikten sonra, konik ışınlı bilgisayarlı tomografi görüntülerinde 1 mm aralıklı koronal ve sagittal kesitler üzerinde; IOF'nin orta noktası ile orta hat mesafesi, IOF'nin orta noktası ile orbita alt sınırı arasındaki mesafe, foramenin mediolateral ve inferosuperior boyutu ölçümleri yapıldı. Ayrıca; koronal kesitlerde foramenin şekli (oval-yuvarlak) ve sagittal kesitlerde foramenin hizasında bulunan diş numarası ve aksiyal kesitlerde aksesuar foramen varlığı incelendi. Bulgular: IOF, sağ tarafta 26 hastada (%43,3) daimi ikinci premolar, sol tarafta 21 hastada (%35) daimi ikinci premolar hizasında lokalizeydi. Aksesuar foramen varlığı değerlendirildiğinde sağ tarafta 10 hastada (%16,7) gözlenirken sol tarafta hastaların 7'sinde (%11,7) gözlendi. Yaş ile sağ ve sol foramenin meziodistal boyutu arasında istatistiksel olarak anlamlı pozitif yönlü zayıf bir ilişki vardır. Yaş ile sağ ve sol foramenin inferior superior boyutu arasında istatistiksel olarak anlamlı bir ilişki bulunmamıştır. Yine yaş ile orta hatta mesafe arasında sağ ve sol tarafta istatistiksel olarak anlamlı pozitif yönlü zayıf bir ilişki vardır. Ancak yaş ile orbita alt sınırına olan mesafe arasında ne sağ ne de sol tarafta istatistiksel olarak anlamlı bir ilişki bulunmamıştır. Sonuç: Çocuklarda infraorbital sinirin blok anestezisi ve ilgili alandaki cerrahi işlemlerde bu anatomik verilerin göz önünde bulundurulması, olası komplikasyonların azaltılmasını ve yapılan işlemlerin başarısının artmasını sağlayabilecektir.

Objectives: The aim of this study is to examine the location, shape, and variations of the infraorbital foramen (IOF) in children to provide valuable information for physicians performing surgical procedures and injections in this region. Material and Methods: The study included 60 pediatric patients. After identifying the IOF on both the right and left sides, measurements were taken on cone-beam computed tomography (CBCT) images using 1 mm interval coronal and sagittal sections. These measurements included: the distance from the midpoint of the IOF to the midline, the distance from the midpoint of the IOF to the inferior border of the orbit, and the mediolateral and inferosuperior dimensions of the foramen. Additionally, the shape of the foramen (oval or round) was assessed on coronal sections, the dental number corresponding to the foramen was recorded on sagittal sections, and the presence of accessory foramina was examined on axial sections. Results: The IOF was located at the level of the permanent second premolar in 26 patients (43.3%) on the right side and in 21 patients (35%) on the left side. When assessing the presence of accessory foramina, they were observed in 10 patients (16.7%) on the right side and in 7 patients (11.7%) on the left side. There was a statistically significant but weak positive correlation between age and the mesiodistal dimension of the foramen on both the right and left sides; age and the distance from the midline on both the right and left sides. However, no statistically significant correlation was found between age and the inferior superior dimension of the foramen on either side; age and the distance to the inferior border of the orbit on either side. Conclusion: In children, these anatomical details can help prevent potential complications and improve success of block anesthesia of the infraorbital nerve and surgical procedures in this field.
