Please be kind enough to explain to me what does \"new maxillary sinus polypoid mucosal thickening/lesions; stable left air cells hypoplasia and opcaification
Welcome to Chat Doctor . Thickening of the maxillary sinus and polypoid appearance may be due to anything from simple sinusitis i.e. inflammation to something sinister as cancer.  You have not mentioned your age or symptoms... You will need an endoscopy and Biopsy and based on the results your condition will become clear.  Please revert to me with details of age, symptoms and clinical findings so that I can help you further. If you are young and relatively asymptomatic then it is likely only sinusitis with polyp that will need medication and probably a small surgery to remove the Polyp. Hope this answered your query
