title: [Pneumocele of the frontal sinus].
abstract: Pneumosinus dilatans frontalis is a rare condition of the frontal sinus. Although the aetiologic mechanism is not yet known, it is presumed that an increased intrasinusal pressure due to a check valve mechanism is responsible for this condition. By measuring intrasinusal pressure we demonstrated this mechanism.
