Günümüz diş hekimliğinde mandibulada yapılacak cerrahi işlemler öncesi mandibular kanala ilişkin varyasyonların değerlendirmesi ve belirlenmesi posterior bölgeye yapılacak oral cerrahi işlemlere yönelik cerrahi esnasında ve sonrasında meydana gelebilecek komplikasyonların önlemesinde önem taşımaktadır. Bifid mandibular kanal mandibulada izlenen anatomik varyasyonlar arasında en sık bildirilen tür olmakla birlikte, tanımlanmasına ve yaygınlığının bilinirliğine yönelik bilgi düzeyinin düşük olduğu tahmin edilmektedir. Bu teknik notta yaygın görülmekle birlikte hakkındaki bilgi düzeyinin eksik olduğu bilinen bifid mandibular kanal varyasyonlarının görünümlerine ilişkin bilgi verilmesi amaçlanmaktadır.

Common but lesser-known anatomical variation of the mandibular canal: Bifid mandibular canal

Öz

Evaluating the variations related to the mandibular canal before oral surgical procedures in the mandible is essential in preventing complications that may occur during and after surgery. Although the bifid mandibular canal is the most frequently reported anatomical variation in the mandible, the level of knowledge regarding its identification and prevalence is estimated to be low. This technical note aims to provide information about the appearance of bifid mandibular canal variations, which are common but lesser known.
