Abstract

The mandibular nerve is the largest of the three branches of the trigeminal nerve. The inferior alveolar nerve also called as inferior dental nerve is a branch of the posterior division of the mandibular nerve.Before traversing the mandibular foramen, it first gives off the nerve to the mylohyoid, a motor nerve supplying the mylohyoid and the anterior belly of the digastric muscles.The lingual nerve is a branch of the posterior division mandibular nerve, which receives sensory innervations from the oral part of the tongue. During routine dissection in the Department of Anatomy, we found the presence of an anomalouscommunication between the nerve to mylohyoid and lingual nerves on the hyoglossus muscle in anadult maleformalin fixed cadaver.Variations in the course of nerve to mylohyoid and its communication with the lingual nerve, have not been satisfactorily described in the anatomical or surgical literature.Variant branching pattern of the mandibular nerve are of great clinical importance since these variations can cause failure to obtain adequate local anesthesia in oral and dental procedures. We assume that this anomalous communication may contain sensory fibers from the inferior alveolar nerve entering in to the lingual nerve through nerve to mylohyoid or some fibres of the motor root ofthe trigeminal nervepassing through the lingual nerve to reach the nerve to mylohyoid.
