Traumatic Neuroma of Bilateral Mental Nerve: A Case Report with Literature Review
摘要
Traumatic neuroma is not a true neoplasm but a neural reaction subsequent to damage of the peripheral nerve. We would like to present a rare case of traumatic neuroma arising from bilateral mental nerve with a history of extracted lower left first molar and lower right second molar more than 10 years ago. A 58-year-old female complained of sporadic pain and numbness sensation over lower face for 2 years. Two submucosal nodules were found at bilateral mandibular vestibule next to mental foramen with mild tenderness on palpation. The panoramic radiography showed two prominent clear radiolucent shadows adjacent to the right and left mental foramens with two residual imprints of extraction wounds at #36 and #47 areas. Excisional biopsy and ablation of bilateral mental nerve with cautery electrodes were performed. Histopathologically, it was consistent with traumatic neuroma. After 1-year follow up, the painful sensation was relieved and no recurrence was found.
