Mastoiditis and Seizures: Is There a Direct Link?
Mastoiditis (infection of the mastoid air cells) is not directly associated with seizure disorders. However, its intracranial complications can cause seizures.
Mastoiditis Basics
- Usually follows untreated acute otitis media.
- Symptoms: postauricular pain, swelling, erythema, protrusion of pinna, otorrhea, fever, hearing loss.
- Diagnosis: clinical + CT temporal bone (coalescence of air cells).
- Treatment: IV antibiotics (ceftriaxone + metronidazole), mastoidectomy if subperiosteal abscess or failed medical therapy.
Complications That Can Cause Seizures
| Complication | Mechanism of Seizures | Frequency |
|---|---|---|
| Meningitis | Inflammatory cytokines, cortical irritation, vasculitis, hydrocephalus | Rare but serious |
| Epidural / Subdural Empyema | Mass effect, cortical venous thrombosis, direct cortical spread | Rare |
| Brain Abscess | Focal irritation, edema, mass effect | Rare |
| Sigmoid Sinus Thrombosis | Venous hypertension, hemorrhage, edema | Rare |
| Labyrinthitis / Vestibular | Not typically seizure-producing | – |
