To the Editor.—In the past five years, we have come across an interesting phenomenon in three patients with recurrent antrochoanal polyp. At initial presentation, polypectomy and intranasal antrostomy were performed. When the patient was found to have a recurrence several months to years later, it was noticed that the polyp now appeared to emerge from the antrostomy site in the inferior meatus rather than from the sinus ostium, as is generally the case.
It is a known fact that antrochoanal polyps have an infective etiology1 and that they emerge from the accessory ostium of the maxillary sinus.2 In the patients described above, it is probable that persistence of the infective etiology (maxillary sinusitis) as well as blockage of the accessory ostium by edema has led to the protrusion of the polyp through the intranasal antrostomy site.
