Persistent inflammation of the sphenoid sinuses located behind the nose.
Medical records that document the frequency and character of your sinusitis episodes are central to supporting a rating. For the higher levels, records showing radical surgery, a diagnosis of chronic osteomyelitis, or repeated surgeries with ongoing symptoms would be relevant. Physician notes, operative reports, and imaging can show these findings.
For the 30% and 10% levels, treatment records showing how many times per year you were prescribed prolonged antibiotic courses of four to six weeks — and whether those episodes required bed rest and physician care — help establish whether episodes were incapacitating. Office visit notes, pharmacy records, and discharge summaries that describe headaches, sinus pain and tenderness, purulent discharge, or crusting support non-incapacitating episode counts.
A 0% rating is supported by imaging such as X-rays or CT scans that show the condition without accompanying documented symptoms or treatment. Statements from you or people who know you describing how recurring episodes affect your ability to work or carry out daily activities can help show the real-world impact of your symptoms alongside clinical records.
