Glass in the frontal sinus: 28-year delayed presentation.

Reports of delayed presentation of foreign bodies in the frontal sinus are infrequent and likely to become rarer with the widespread availability of computed tomography in the last 2 decades. We present a case in which glass from a road traffic injury was found in the frontal sinus, causing symptoms of frontal sinusitis 28 years after the initial injury. We also present a review of the literature.
