In November 1881, Friedrich Bezold described a coalescent mastoiditis with pus escaping through the incisura digastrica, forming an abscess spreading along the digastric muscle toward the chin, filling the retromandibular fossa, and/or spreading further along the sternocleidomastoid, trapezius, and splenius muscles, a condition that was fatal when the vertebrae and skull base were affected.1-3 In the preantibiotic days of Bezold, otitis media acuta was complicated by mastoiditis in 50% of cases, 20% of which involved a Bezold abscess. Since the advent of modern antibiotic therapy, acute mastoiditis occurs in only 0.24% of cases of acute otitis media and leads to abscess formation in 50% of these cases. So even though mastoidal complications of otitis media are rare today, they are more often followed by extramastoidal complications.4
