Paediatric Mastoid Subperiosteal Abscess: Diagnostic and Tre
Abstract
Mastoid subperiosteal abscess (SA) is the most common complication of acute mastoiditis. Today, no uniformly accepted diagnostic or treatment protocols exist. Imaging studies for all patients and mastoidectomy plus myringotomy, traditionally constitute the gold-standard of treatment methods. However, more conservative approaches viewed as safe and reliable alternative options for the clinician have recently gained popularity. In this review authors try to answer some vital questions regarding the diagnosis and management of SA in children, based on the relevant literature and their personal experience.

Introduction
Mastoid subperiosteal abscess is the most common complication of acute mastoiditis, classified in the spectrum of intratemporal complications of acute otitis media. The classic sequence of SA formation is the extrusion of pus beneath the periosteum through infectious erosion of the outer cortical bone at the mastoid protuberance or through pre-existing anatomical pathways, such as vascular channels and the tympano-mastoid suture [1,2].....
