Long Term Silicone Implant Risk for Chronic Sinusitis
A silicone implant which has been otherwise symptom free for 20 years is unlikely to be responsible for your chronic sinus condition. Having a deviated nasal septum, allergies, narrow sinus outflow tracts, enlarged turbinates etc. are more that likely the issue. I recommend a comprehensive nasal and sinus evaluation with an experienced Facial Plastic Surgeon/ ENT who can evaluate your situation, exam your nose, review your CT scan, allergy work up and nasal endoscopy studies and recommend an appropriate plan of therapy. Surgical and non-surgical options should be considered. Best wishes.
