ABSTRACT

Hypoglossal canal (HC) which begins from very slightly above the inner part of the anterolateral portion of the foramen magnum and is located above the occipital condyle of the occipital bone. The aim of this study is to examine HC morphology and variations using cone beam computed tomography (CBCT). The morphology and types of HC were investigated with 303 CBCT images (606 side). Type 1 variation in 606 HC examined becomes the most commonly observed type (57.3%) while type 5 variation was the least common type of variation (0.8%). Type 1 HC was statistically higher in males (p=0.004). Because of HC, which is an anthropologically important point and enters the field of images in CBCT scan, it is recommended that dental radiologists should be aware of their variations and be wary of the pathologies that may occur in this region.

Keywords: CBCT; foramen magnum; hypoglossal canal; occipital condyle

ABSTRAK

Saluran hipoglosus (HC) yang bermula di bahagian atas sedikit pada bahagian dalaman anterosisi foramen magnum dan terletak di atas kondil oksipital tulang oksipital. Tujuan kajian ini adalah untuk mengkaji morfologi dan variasi HC menggunakan tomografi pemancar kon berkomputer (CBCT). Morfologi dan jenis HC dikaji dengan 303 imej CBCT (sisi 606). Variasi jenis 1 pada 606 HC yang disemak menjadi jenis yang paling sering diperhatikan (57.3%) sementara variasi jenis 5 adalah jenis variasi yang paling jarang (0.8%). HC Jenis 1 secara statistik lebih tinggi pada lelaki (p = 0.004). Oleh kerana HC, yang merupakan titik penting antropologi dan memasuki bidang pengimejan dalam imbasan CBCT, disarankan agar ahli radiologi gigi harus mengetahui variasinya dan berhati-hati dengan patologi yang mungkin berlaku pada bahagian ini.

Kata kunci: CBCT; foramen magnum; kondil oksipital; saluran hipoglosus
