Aim of the work – to compare the frequency of upper respiratory tract (URT) involvement in patients with ANCAassociated vasculitides (AAV), to reveal its main clinical and radiological patterns and to estimate their association with the serological profile (ANCA presence and type).Material and methods. This retrospective study evaluated 369 patients with granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). The enrolled patients were diagnosed with AAV according to the ACR criteria, CHCC classification (2012) and EMA algorithm. Patients with URT manifestations underwent standard ENT assessment and X-ray/CT. Serum ANCA levels were measured by ELISA.Results. URT involvement was diagnosed in 280 (75.9%) patients with AAV. It was significantly more common amongthe patients with GPA (86.4%) and EGPA (85.5%) compared with the MPA group (29.2%) (p
