title: Silent sinus syndrome: a mechanical theory.
abstract: We present the case of a progressive enophthalmos, 23 years after an orbital floor fracture treated conservatively. Imaging demonstrated orbital fat herniation into the pterygopalatine fossa and a collapse of the maxillary sinus walls. We hypothesise that some "silent sinus syndrome" might be caused by an aspiration phenomenon resulting from masticatory muscle movements.
