Hello, You have history of having sinus surgery done. Presently, your CT shows sphenoid sinus moderate to severe mucosal thickening and bilateral posterior ethmoid and maxillary sinus mild mucosal thickening. You have lost weight and appetite post surgery and have constant drainage that causes you to vomit. Your third surgery was painful. Removal of turbinates may cause pain and dryness. Post-operative infection may cause such symptoms. Patients with pre-operative sinusitis have an increased risk of infection. To prevent nasal obstruction , much of the cartilage in the nasal septum is removed. Small scar bands may occur post surgery and may require minor procedure by your treating doctor post surgery, get a follow up examination at the earliest. If there is a clear nasal discharge post surgery, CSF leak a very rare complication may be suspected and needs urgent repair as it may lead to infection and further complications. Sometimes impaired sense of taste or smell occurs post surgery causing loss of appetite. Get clinically re- examined, get necessary procedures done if required. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
