Chronic maxillary atelectasis (CMA) is traditionally described as a rare, acquired condition of persistent and progressive antral wall collapse causing a reduction in maxillary sinus volume. In a handful of cases, CMA has been identified in patients with previously normal computed tomography (CT) imaging. However, maxillary atelectasis occurring rapidly after pituitary surgery, despite a normal pre-operative CT scan, has not previously been described in the literature.
