Bilateral Nasal Polyp with Unilateral Pathology

Abstract

ABSTRACT The antrochoanal polyp or Killian's polyp is a benign, solitary lesion that affects mainly children and young adults. It is unilateral in occurrence though a few cases of bilateral antrochoanal polyps have also been reported. We report a unilateral antrochoanal polyp extending to the opposite side, a presentation not mentioned in literature till date.
