Quand la rhinosinusite revele une pathologie systemique.

This retrospective analysis is concerned with 10 patients suffering from granulomatosis with polyangitis (GPA, Wegener's disease), who were followed up in a tertiary care Ear, Nose, and Throat (ENT) department. The inaugural events took place in the ENT field (8 patients), the lung (2 patients), the vestibule (1 patient), or the oral cavity (1 patient). The ENT manifestations during the disease evolution involved the rhinologic (osetocartilaginous--6 cases; mucosal--9 cases), the otologic (3 cases), or the laryngeal area (2 cases). Facial pain was noted in 6 cases and residual hyposmia in 5. We observed 5 cases of lung involvement, 3 cases of renal involvement, and 4 cases of ocular involvement. An aseptic meningitis was seen in 1 case and the muscles were affected in 6 cases. The average delay between symptom onset and diagnosis was 26 months. Endoscopy, imaging techniques, and determination of antineutrophil antibodies (ANCA) were used to reach the diagnosis. Sinus biopsies were contributive in 6 cases. The patients were treated with immunosuppressive drugs and/or surgery. After treatment, remission was obtained in 6 patients.
