Case report details surgical resection of an accessory canal in post‐traumatic trigeminal neuropathy, suggesting effective treatment methods.
Aim To describe an unusual case of post‐traumatic trigeminal neuropathy affecting an accessory canal of the canalis sinuosus related to a maxillary central incisor. Summary This case report presents a 48‐year‐old female patient who suffered from neuropathic pain following the crown placement and endodontic treatment of a left maxillary central incisor (tooth 21). A cone beam computed tomographic (CBCT) scan of the anterior maxilla revealed an accessory canal apical to tooth 21, with extruded sealer within the bony channel. A sustained resolution of the patient's symptoms was achieved following apicectomy of the tooth and surgical resection of the accessory canal. The tooth remained asymptomatic at the 5‐year follow‐up.
