Coalescent (or confluent) otomastoiditis with abscess
Definitions
AM: Active infection in mastoid without destruction of mastoid septations or cortex
ACOM: Acute middle ear-mastoid infection with progressive bony resorption & demineralization due to intramastoid empyema
ACOM + abscess: Coalescent mastoiditis with resultant intracranial or extracranial abscess
