A man who experienced a displaced mandibular fracture complains of discomfort at the historical fracture site near the mental foramen, where a movable, tender mass is detected upon palpation. The most accurate preoperative diagnosis is_______________?
Show answer Hide answer
Answer: D. Traumatic neuroma
Explanation
A traumatic neuroma is a painful, reactive proliferation of nerve fibers following physical nerve injury. The mental foramen region is susceptible to nerve damage during mandibular fractures or surgical procedures. Palpation typically reveals a small, mobile, and exquisitely tender submucosal mass at the injury site. Traumatic neuromas represent disorganized attempts by severed nerve axons to regenerate through scar tissue. They are not true neoplasms but rather reactive hyperplastic growths following trauma or extractions. Surgical excision with removal of the contributing local irritation is the standard treatment approach.
Dentists and oral surgeons must consider traumatic neuroma when patients report persistent pain after jaw surgery. Detailed patient history regarding previous fractures helps differentiate neuromas from other benign oral tumors. Managing chronic facial pain requires identifying nerve entrapment or traumatic injury sites accurately. Neuroleiomyoma is a rare benign nerve sheath tumor unrelated to post-traumatic nerve regeneration processes. Neurofibroma is a benign nerve tumor usually associated with neurofibromatosis syndromes rather than jaw trauma. Trigeminal neuralgia causes severe paroxysmal facial pain without forming a palpable movable submucosal nodule.
