Q

What is the medical treatment for nasal polyps?

A

Oral and nasal steroids

  • High dose prednisolone and nasal steroid for 20 days will eliminate 50% of polyps
  • Lower bioavailability in modern nasal steroids
  • Poor response in certain groups
  • Intranasal injection not effective

Immunotherapy

Q

How do you diagnose rhinosinusitis?

A

SINUS RADIOGRAPHS
Poor visualisation of the osteomeatal complex and the anterior ethmoidal sinuses.
-High rate of false positive findings
-Less expensive, but not as accurate as newer imaging
