SUGAR AND CHLORIDE IN FLUID FROM INTRANASAL CYSTS

Abstract

IN 1941, Eichelberger and Lindsay¹ reported findings with regard to the chemical composition of fluid contained in intranasal cysts; Lindsay² again reported on this subject in 1942. These authors found relatively large amounts of sugar and chloride in this fluid. Such determinations had not been reported previously. Their findings came to light during recent treatment of a patient at the Mayo Clinic. REPORT OF A CASE An 18-year-old girl had had myxomatous polyps removed from the left nasal chamber on four previous occasions, two years and one year prior to the present visit.
