Chronic sinusitis can be treated successfully with the right medication. But you need a good evaluation.
As far as the hearing loss is concerned, the treatment depends on the type and degree of hearing loss.
Next Steps
1. Visit an ENT specialist for a good workup including a CT Scan of the nose and paranasal sinuses
2. You will need an Audiometry to assess the type and degree of hearing loss and the treatment options will depend on that
Health Tips
