January 1, 2010  |  Alexander Langerman, MD, Farhad Sigari, MS, MD, and Robert Naclerio, MD


Unilateral sinus disease has a wide differential diagnosis. When a patient has a history of maxillary dental work on the same side as the sinusitis, a foreign entity introduced during or subsequent to the dental manipulation must be considered. We present a case of calcified...
