Objective: To determine whether the subperiosteal abscess (SPA) volume in acute coalescent mastoiditis (ACM) as measured in imaging studies, should influence the decision-making process between performing mastoidectomy versus needle aspiration or incision and drainage (I&D) as the initial treatment of SPA.
Setting: Single tertiary referral center.
Patients And Methods: The records of all pediatric patients admitted with ACM between 1/2012 and 12/2023 were retrospectively reviewed.
