Polyposis which includes sinonasal polyposis, antrochoanal
polyps and polyps with fungal aetiology is present in 34.
When compared to antrochoanal
polyps, the nasal polyps have many more submucous glands and much more eosinophilic infiltration (5, 6).
polyps are the most common form of choanal polyps.
It is still indicated in cases of irreversible scarring, polypoidal mucosal inflammation, antrochoanal

The most common indications are: chronic sinusitis refractory to medical treatment, recurrent sinusitis, nasal polyposis, antrochoanal
polyps and sinus mucoceles.
Most choanal polyps arise from the maxillary sinus, and they are called antrochoanal
polyp originates from maxillary antrum and extends through the ostium to the nasal cavity and nasopharynx.
