A Case of Traumatic Neuroma in Infraorbital Nerve / 대한이비인후과학회지

ABSTRACT

The term "traumatic neuroma" is used to describe the nodular mass of regenerating axons and Schwann cells that develop at the end of a proximal nerve stump following partial or complete transection of a nerve. Traumatic neuromas of the head and neck are relatively rare, and pain is the main symptom. Several cases of the traumatic neuromas of the head and neck have been reported in the literature at such sites as oral cavity, maxillary division of the trigeminal nerve, the inferior alveolar of the mandible, the auriculotemporal nerve, the glossopharyngeal nerve, and the facial nerve. We experienced a 60-year-old woman with a painful mass in her right cheek, appearing 10 years after she had pricked her right cheek with an umbrella. This mass was excised and the pathologic diagnosis was traumatic neuroma. We report this case here with a review of the literature.
