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 Highmore( Maxillary sinus) and grow towards choana they are known as antrochoanal polyp . 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 unnecessary surgery for other sinusesthat are not involved. Radiological investigations include a C.T.ScanParanasal Sinuses or aM.R.I.This will help in .differentiating the sphenochoanal polyp from an antro choanal polyp.Diagnostic nasal endoscopy will confirm the diagnosis. Once the diagnosis is made surgical removal must be done. This caseis presented here because of its rarity and also to stress the use of endoscopes in diagnosis and surgical managementof nasal polyps.
