Case Report : Aberrant buccal nerve in the retromolar canal

Aberrant buccal nervesarising from the mandibular canal and passing through the retromolar canal into the buccinator muscle is a rarely encountered anatomical variation. This paper will discuss two cases of such variations. In the first, paresthesia developed due to injury to the abnormal nerve during dissection, due to our inexperience. In the second, a cautious dissection based on the experience gained in the first case was performed, and no complication was observed. The related literature suggests thatbuccal nerve connections can pass through a retromolar canal.We conclude thatwhen anesthesia remains incomplete during mandibular wisdom tooth extraction, an aberrant retromolar nerve passage should be suspected. In such cases, computed tomography should be performed if possible, and a cautious surgical approach should be adopted to preserve functioning of retromolar sensory nerves.
