Dynamic radiologic changes in repeated barotraumatic frontal sinusitis: A CARE case report.

Résumé

INTRODUCTION: Flight staff are at particular risk of iterative sinus barotrauma. We here report a case of barotraumatic atelectasic frontal sinusitis with dynamic radiologic change in frontal sinus volume.

CASE REPORT: A 46-year-old air pilot was referred for right frontal pain occurring at each landing. Two sinus CT scans were taken: one after a period of intense flying and the other after a month without flying. In the right frontal sinus, a type-3 Kuhn cell changed in volume from 6×11×12mm to 13×18×19mm. The alteration involved a modification in the medial wall, which was demineralized and changed position within the frontal sinus. Removal during endoscopic frontal sinusotomy allowed complete resolution of pain.

DISCUSSION: This article reports radiologic change in a frontal sinus wall in a setting of repeated barotraumatic frontal sinusitis with a dynamic atelectasic component. In iterative barotrauma, we advocate imaging at different time points. When the ostial obstruction is identified, functional aeration surgery can be applied.
