Insights
Drug-resistant bacteria and nursery school spread contribute to severe acute mastoiditis and mastoid lesions. Early antibiotic treatment and myringotomy are crucial, with surgery for severe cases.
Area of Science:
- Otolaryngology
- Pediatric Infectious Diseases
- Radiology
Background:
- Acute mastoiditis, an emergency condition, involves middle ear inflammation spreading to the mastoid antrum, risking progression to subperiosteal abscess and meningitis.
- Mastoid cavity opacity on CT scans is frequently observed in recurrent or intractable otitis media and mastoiditis.
- Nursery school attendance and drug-resistant bacterial strains are implicated in severe or intractable cases.
Abstract:
Increased otitis media rendering acute mastoiditis and mastoid lesions severe or intractable appear to be related to dominant drug-resistant strains and the dissemination of nursery school attendance. Acute mastoiditis involves middle-ear inflammation spreading to the antrum mastoideum and accompanied by subcutaneous abscess. This emergency condition risks progression to subperiosteal abscess and meningitis. Mastoid cavity opacity in computed tomography (CT) scan often occurs with recurrent or intractable otitis media similar to that with mastoiditis. Four of the 8 cases of mastoiditis we treated were infant in whom upper respiratory tract pneumococcus and group A streptococcus were detected. Treatment involved antibiotics and myringotomy in all cases and surgery in two. Nine of the 10 cases of mastoid lesions with otitis media we saw were infant. All had pneumococcus detected, with accociated sinusitis.
