Area of Science:

  • Neurology
  • Otolaryngology
  • Pathology

Background:

  • Meningiomas are tumors that arise from the meninges, the membranes surrounding the brain and spinal cord.
  • Middle ear meningiomas are uncommon, often presenting as an extension of intracranial or temporal bone tumors.
  • These tumors can cause a variety of symptoms due to their location and potential mass effect.

Purpose of the Study:

  • To retrospectively review the clinicopathologic features of meningiomas involving the middle ear.
  • To analyze the clinical presentation, histological findings, and outcomes of patients with middle ear meningiomas.

Main Methods:

  • Retrospective review of six cases of meningiomas involving the middle ear.
  • Analysis of patient demographics, clinical symptoms, surgical findings, histopathology, and follow-up data.

Main Results:

  • Six meningiomas involving the middle ear were identified, predominantly in women (5/6) aged 45-67 years.
  • Common symptoms included gait/balance issues, chronic otitis media, diplopia, and hearing loss, with a long duration of symptoms (median 10 years).
  • All tumors were histologically syncytial (meningotheliomatous) meningiomas; four patients experienced recurrences after initial surgery for posterior fossa/temporal bone meningiomas.

Conclusions:

  • Meningiomas involving the middle ear are rare and often represent extensions of intracranial or temporal bone tumors.
  • These tumors typically present with a long history of varied symptoms and can recur after treatment.
  • Complete surgical resection and long-term follow-up are crucial for managing middle ear meningiomas.
