title: Barotrauma secondary to inflammatory maxillary sinus polyp: a case report.
abstract: Sinus barotrauma, secondary to mucosal disturbances, is a common finding within the aviation community. Multiple etiologies have all led to mucosal inflammation and thickening with potential obstruction of the sinus osteomeatal complex, especially during the barometric changes of flight. Obstruction can, therefore, lead to problems with sinus pressure equilibration with atmospheric pressure, and can lead to barosinusitis. We present a case of a U.S. Air Force Command Pilot with acute left sinus barotrauma during descent while flying a T-37 aircraft, along with a brief review of the pathophysiologic processes involved during barotrauma. An inflammatory polyp within his sinus was identified by plain radiography, confirmed with computed tomography, and subsequently excised. The patient had complete resolution and clearance to fly after an uneventful 4-wk convalescence and altitude chamber flight. This is the first case of sinus barotrauma secondary to an inflammatory maxillary sinus polyp, confirmed by histologic diagnosis, reported in the aeromedical literature.
