Traumatic Neuroma in the External Auditory Canal

Area of Science:

• Otorhinolaryngology
• Neuropathology

Background:

• Traumatic neuroma is a rare proliferation of nerve cells, typically occurring after nerve injury.
• Neuromas in the external auditory canal are exceptionally uncommon, with few documented cases.

Purpose of the Study:

• To report a rare case of traumatic neuroma in the external auditory canal.
• To review the existing literature on external auditory canal neuromas.

Main Methods:

• Case presentation of a 50-year-old female patient with an external auditory canal mass.
• Surgical excision of the mass.
• Histopathological examination for diagnosis.
• Literature review.

Main Results:

• A 7 × 5-mm mass was identified on the anterior wall of the external auditory canal.
• The mass was successfully removed surgically.
• Histopathology confirmed the diagnosis of neuroma.
• No recurrence was observed post-excision.

Conclusions:

• Traumatic neuroma is a rare but possible diagnosis for masses in the external auditory canal.
• Surgical excision is an effective treatment for external auditory canal neuromas.
• Further case reporting is valuable for understanding this rare condition.
