Otolaryngologic manifestations of small vessel vasculitis.

Objective: The aim of the present study is to review the clinical manifestations associated with small vessel vasculitis (SVV) as they pertain to the head and neck region.

Methods: A retrospective analysis was performed, including 34 individuals that filled the American College of Rheumatology criteria for the diagnosis of necrotizing vasculitis. Seven patients were classified as suffering from Wegener's granulomatosis (WG), 18 from microscopic polyangitis (MPA), and the remaining 19 were unclassified (unclassified small vessel vasculitis, USVV).
