A Rare Case Of Accessory Nerve To Mylohyoid Communucating With Lingual Nerve And Its Clinical Implications

Nerve to mylohyoid is a branch of inferior alveolar nerve given just before it enters the mandibular foramen. Itcourses inferior to the origin of mylohyoid and supplies both mylohyoid and anterior belly of digastric along itssuperficial surface. An accessory branch from inferior alveolar nerve was discovered during routine dissection.The nerve was found only on the left side. Additionally, a communicating branch was seen between lingual nerveand accesoory nerve to mylohyoid. Knowledge of the variations of the mandibular nerve, its branches andcommunications are clinically important especially for attaining adequate local anaesthesia during routineoral and dental procedures.
