Coalescent mastoiditis

Coalescent mastoiditis occurs as bone is remodeled and resorbed from pressure necrosis, inflammation, and increased osteoclastic activity in the setting of an acute otologic infection. This finding necessitates treatment with antibiotics and surgery, which typically involves pressure equalizing tube placement and mastoidectomy. Herein, we review diagnostic and treatment considerations as well as surgical technique in the management of acute coalescent mastoiditis.
