What long-term treatments helped you manage chronic sinusitis?

[HarperT]

I've been dealing with chronic sinusitis for over a year, with constant facial pressure, congestion, and recurrent infections that antibiotics only temporarily fix. My ENT has suggested trying a longer course of nasal corticosteroids and possibly moving towards a sinus CT scan to evaluate for structural issues. For others who have found successful long-term management strategies, what combination of medications, irrigation routines, or even surgical interventions finally provided you with consistent relief and improved your quality of life?
