Intracranial Polyps in Patients with Samter's Triad

Abstract

Background We describe three patients with Samter's triad (nasal polyps, aspirin intolerance, and asthma) with skull base dehiscence in whom the polyps extended into the extradural space and also resulted in hypertelorism and widening of the nasal bridge. Methods One patient died in a road traffic accident while awaiting surgery. The other two patients underwent endoscopic resection of the polyps with a combined osteoplastic flap. Results Histology confirmed benign eosinophilic polyps with edematous stroma and a markedly thickened basement membrane. There were no complications or revision procedures. Both are symptomatically well with improvement of the hypertelorism. Conclusion These cases indicate that polyps in Samter's triad may be extremely aggressive, resulting in intracranial extension. A combined endoscopic and osteoplastic flap approach is a safe and effective surgical option.
