    Area of Science:

    • Otolaryngology
    • Neurosurgery
    • Infectious Diseases

    Background:

    • Chronic recurrent mastoiditis can present with complex complications.
    • Previous intracranial infections, such as posterior fossa abscesses, increase the risk of further otologic sequelae.
    • Acute otitis media is a common precursor to serious middle ear and mastoid infections.

    Observation:

    • An unusual case involving a large labyrinthine sequestrum was identified during a mastoidectomy.
    • The patient had a history of a posterior fossa abscess four years prior, stemming from acute otitis media.
    • The sequestrum was located within the bony labyrinth, indicating extensive disease progression.

    Findings:

    • Surgical intervention revealed a significant bony fragment (sequestrum) within the inner ear structures.

  • The sequestrum's presence complicated the management of chronic mastoiditis.
  • Histopathological analysis would be crucial to confirm the nature and origin of the sequestrum.

    • Implications:

    • This case underscores the potential for deep labyrinthine involvement in severe mastoid infections.
    • Aggressive surgical management, including ablative procedures with facial nerve preservation, may be necessary.
    • Early recognition and treatment of otitis media and its complications are vital to prevent such outcomes.
