Summary

Active chronic otitis media affects 1.5% of adults. The annual risk of developing a brain abscess from this condition is low (1 in 10,000), but lifetime risk is higher, especially for males.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Epidemiology

Background:

  • Active chronic otitis media (COM) affects 1.5% of adults, posing a significant management challenge.
  • Preventing COM complications is crucial due to potential mortality, with intracranial abscess being a primary concern.

Purpose of the Study:

  • To determine the risk of otogenic intracranial abscesses in adults with active COM.
  • To analyze the incidence and risk factors associated with these abscesses.

Main Methods:

  • A 10-year retrospective review of all otogenic intracranial abscesses in Scotland was conducted.
  • A 15% allowance was incorporated to account for potentially missing records.

Main Results:

  • The annual risk of developing an abscess in adults with active COM is approximately 1 in 10,000.
  • Males are three times more likely to develop an abscess compared to females.
  • The lifetime risk for a 30-year-old with active COM is estimated at 1 in 200.
  • Five percent of abscesses occur post-mastoid surgery.

Conclusions:

  • While the annual risk is low, the lifetime risk of intracranial abscess in active COM patients is significant.
  • Current evidence does not support that surgery reduces this risk.
  • Further research is challenging due to required follow-up duration and sample size.
