A case of mastoiditis complicated with bezold abscess in the only hearing ear

Bezold abscess (BZ) is defined as a deep neck abscess as the result of mastoiditis with mastoid tip erosion after otitis media (OM). Despite its rare occurrence due to the early intervention of ear infection with antibiotics, diligently looking for this complication is important, especially in the immunodeficient population. The utilization of radio imaging remains crucial in the management of acute OM with complications. The contrast-enhanced computed tomography facilitates the diagnosis and provides a glimpse of the disease extension. Early recognition and intervention are vital for a good outcome. The authors present a case report of a mastoiditis complicated with a BZ in the only hearing ear. The risk factors, presentations, and treatment options are discussed, along with the review of the literature.
