Sphenochoanal polyp a case report

Single nasal polypi presenting at the choana are a common entity in ENT practice. Since they usually arise from the Antrum of High-more( Maxillary sinus) and grow towards choana they are known as antrochoanal pol-yp . Choanal polyp arising from the sphenoid sinus and presenting at the choana are rare. These are known as spheno –choanal polyp, It is imperative that we differentiate between the two polyps for two reasons – 1, to give a complete disease clearance 2, to prevent un-necessary surgery for other sinuses that are not involved. Radiological investigations in-clude a C.T.Scan Paranasal Sinuses or a M.R.I. This will help in differentiating the sphenochoanal polyp from an antro choanal polyp. Diagnostic nasal endoscopy will con-firm the diagnosis. Once the diagnosis is made surgical removal must be done. This case is presented here because of its rarity and also to stress the use of endoscopes in di-agnosis and surgical management of nasal polyps.
