Wegener's granulomatosis: current trends in diagnosis and management

Wegener's granulomatosis is an idiopathic, systemic vasculitis characterized by the formation of necrotizing granulomas of the respiratory tract in addition to focal or proliferative glomerulonephritis. Diagnosis is made by a combination of physical examination, laboratory studies and tissue biopsy. Head and neck manifestations are abundant and varied; common sites of involvement include the middle ear, nose and sinuses and subglottis. The mainstay of treatment remains systemic therapy using a combination of glucocorticoids and immunosuppressants. The otolaryngologist plays a key role in the diagnosis and treatment of head and neck complications of the disease. A surgical role exists for the management of nasal and sinus disease as well as laryngeal and tracheal disease.
