2.3 Treatment groups and complications
The single complication group (SCG) was defined as all children
diagnosed with complicated mastoiditis and SPA alone. Multi
complications group (MCG) included patients with additional
intratemporal or intracranial complication (peri-sinus fluid/abscess,
epidural abscess, SST, and acute meningitis).
Complications were defined as either a SPA or any clinical finding on
physical examination and/or by imaging (post-contrast head CT or head
MRI) pre/intra-operatively.
