Allocation to intervention
Randomised controlled trial
Query!
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be enrolled from the primary investigators clinic. If willing to volunteer they will have an identifier number generated by computer program to ensure anonymity. The identifier numbers will then be randomized by a third party using a random sequence generator. Concealment of allocation will be accomplished by sealed opaque envelopes.
Query!
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
We will use block randomization. 40 patients will be recruited and allocated equally to each group (allocation ratio 1:1).

Summary
Brief summary
Chronic Rhinosinusitis is a chronic condition of the nose and paranasal sinuses. Patients suffering from chronic sinusitis complain of headaches, nasal congestion and thick nasal discharge. The burden of chronic sinusitis on our society is high. It causes increased cost to health care system and decreased productivity with loss of work days. No single treatment was found to control the symptoms of chronic sinusitis. It was found that dry mannitol delivered to the lungs of patients with cystic fibrosis makes the secretions less thick, easier to clear and symptoms better controlled. We believe these effects are transferrable to chronic sinusitis patients. We believe that mannitol will help loosen their nasal discharge, making it easier to clear and eventually control their symptoms better
