Intracranial polyps in patients with Samter's triad.

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.
