Superselective Intra-arterial Chemotherapy of Advanced Paranasal Sinus Tumors

Twenty-four patients with advanced paranasal sinus tumors were treated with combined superselective intra-arterial and systemic chemotherapy, yielding an immediate satisfactory tumor response rate of 91%, significantly better than previously reported. Eight patients had craniofacial surgery circumvented because of complete or near complete response. Repetitive uncomplicated catheterization of the pterygoid segment of the internal maxillary artery using a coaxial system is the cornerstone of successful induction chemotherapy. Strenuous screening of medical status is mandatory for this aggressive introduction chemotherapy.
