Traumatic Neuroma of Bilateral Mental Nerve: A Case Report with Literature Review

雙側下顎頦神經外傷性神經瘤:病例報告與文獻回顧

摘要


外傷性神經瘤是周邊神經組織受到傷害後的一種增生反應。在臨床表徵上,它可能爲痛或不痛的的腫塊,通常伴隨有外傷的病史。本報告提出一罕見雙側下顎頦神經外傷性神經瘤病例。患者爲一位五十八歲女性,來院主訴爲下顏面部疼痛與麻木兩年之久。在下顎雙側近頦孔前庭處可觸模到兩顆結節腫塊,在觸診時會引起患者的下顏面疼痛感。根據理學與影像學診斷,而且患者左側曾患峰窩性組織炎有切開引流的病史,右側有拔牙的病史。初步診斷爲外傷性神經瘤,但不能排除神經纖維瘤與神經鞘瘤。於是爲患者安排手術,切除雙側腫瘤與頦神經。組織病理切片下證實爲外傷性神經瘤。串者一年後追蹤,下顏面疼痛感已解除並無復發症狀。因此病例雙側的罕見性,並針對外傷性神經瘤的成因、臨床症狀與治療做文獻回顧,故提出此報告。

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.
