Mastoid Osteoma - Is "Trauma" A Possible Etiologic Factor.

Area of Science:

• Otolaryngology
• Neurosurgery
• Pathology

Background:

• Osteomas are benign bone tumors, with mastoid osteomas being a rare subtype.
• Postaural swelling can be caused by various conditions, necessitating accurate diagnosis.

Observation:

• A 19-year-old female presented with a three-year history of painful postaural swelling.
• Clinical and radiological assessments confirmed the diagnosis of mastoid osteoma.
• The patient reported a history of trauma preceding the swelling.

Findings:

• Surgical removal of the symptomatic mastoid osteoma was performed via cortical mastoidectomy.
• The osteoma was successfully excised, alleviating the patient's symptoms.

Implications:

• Early intervention for symptomatic mastoid osteomas, regardless of size, is crucial to prevent progression to giant osteomas.
• Trauma may play a role in the etiology of mastoid osteomas, warranting further investigation.
• This case contributes to the literature on rare mastoid osteomas and their potential association with trauma.
