The polyp is a chronic inflammation of the lateral nasal wall and ethmoid mucosa in the form of an edematous sac. The incidence of polyps increases after the age of 20. Its appearance is in the form of a pale, fluid-filled mass. Causes include mucosal contact; that is, swelling of a mucosa with infection. Nasal strictures increase this swelling. Infection, allergy, aspirin sensitivity contribute to the formation of polyps by narrowing these areas more. Allergy incidence is detected in only 30% of patients with polyps. Acute upper respiratory tract infections cause polyps to grow. Polyps are also seen in fungal sinusitis. Medical or surgical treatment of a nasal polyp will absolutely reduce asthma symptoms. Polyps are usually multiple and bilateral. Patients with polyps have complaints of nasal congestion, clear and yellow-green nasal discharge, olfactory disorder, hoarse voice, and facial pain. They feel that the polyp is moving inside the nose while trying to breathe through the nose. Diagnosis is made by endoscopic nasal examination and paranasal sinus CT. Nasal polyp treatment is medical and surgical. The success rate is high with endoscopic sinus surgery. However, recurrences are encountered in some cases. Recurrence after a well-done surgery does not mean failure; is a feature of the disease.
