Inverted papilloma is a benign type of true tumor. It can also be diagnosed clinically as a precancerous lesion, which can be caused by viral infection, inflammatory stimulation, and metabolic reactions. Because of its correlation with papilloma virus, early detection, early diagnosis and treatment are required. After surgery, regular follow-up is needed, and nasal endoscopy and sinus CT examination are feasible. Usually, a light diet is the mainstay, with less spicy and stimulating food, and do not use tobacco and alcohol as stimulants.
