Nasal polyps are a relatively common otolaryngological disease with a high incidence rate clinically. The symptoms are numerous and may include nasal congestion, runny nose, reduced sense of smell, headache, and dizziness. For some patients, the polyps can be seen with the naked eye during examination, especially if there are many polyps or if they are located near the front of the nose. Generally, after using an anterior rhinoscope to widen the nostrils, the polyps can be seen. However, in some cases, the polyps grow in hidden areas, such as in the olfactory region or within the sinuses, making them difficult to detect with the naked eye. In such cases, a nasopharyngoscopy or sinus CT scan can be performed for more accurate diagnosis.
