We performed nerve reconstruction concurrently with resection of a benign tumor-like lesion in the inferior alveolar nerve and obtained good sensory recovery. The patient was a 65-year-old woman who had had sensory disturbance in the left mental nerve region since July 2015 and was referred to our department by a dentistry department of a nearby hospital in October 2015 with a chief complaint of sensory disturbance at the same site. Panoramic radiography and computed tomography scanning confirmed enlargement of the left mental foramen, while magnetic resonance imaging revealed low signal intensity on T1-weighted images. The above-mentioned findings led to the clinical diagnosis of a neurogenic tumor, for which reconstruction of the inferior alveolar nerve that was resected during tumor resection under general anesthesia was performed in November 2015. Histopathological findings led to the diagnosis of schwannoma-like benign tumor-like lesion. On assessment 18 months after the operation, the sensory disturbance of the mental nerve region showed improvement.
