title: Giant osteoma of the sphenoid sinus reached by an extradural transbasal approach: case report.
abstract: Giant osteomas of the paranasal sinuses are infrequent. Those of the sphenoid sinus with neurological symptoms are even rarer. We report here the case of a woman with a giant osteoma of the sphenoid sinus who presented with bitemporal quadrantanopsia and underwent operation via an extradural transbasal approach.
