Background: Mastoid abscess remains a recognised complication of otitis media despite the advent of antibiotics. The objectives of this study were to describe the risk factors in patients with mastoid abscess following acute and chronic otitis media and discuss the management of this infection.
Methods: A retrospective analysis was done on all patients who underwent mastoidectomy for mastoid abscess from January 2002 to December 2007. Data on the patients’ presentation, associated complications, management, and follow-up were analysed.
Results: A total of 12 patients were enrolled in this study population. Group A consisted of patients with mastoid abscess preceded by acute otitis media, while Group B consisted of patients with mastoid abscess and chronic otitis media. In Group A (n = 7), 4 patients had a pre-morbid immunocompromised condition, but they did not have cholesteatoma. None of the patients in Group B (n = 5) had any pre-morbid illnesses. Out of 12 patients, 7 patients had associated extracranial complications, and 1 patient had intracranial complications. Most patients recovered well after mastoidectomy. Recurrence was noted in 1 patient who had acute lymphoblastic leukaemia.
Conclusion: Mastoid abscess is still a recognised complication of acute otitis media, especially in patients who are immunocompromised. Immunocompetent patients may also develop mastoid abscess following chronic otitis media associated with cholesteatoma. Thus, early treatment of otitis media and close vigilant follow-up are advocated to ensure prompt detection of mastoid abscess complications.
