Key Points :
1) Intranasal steroid injections were historically very effective, but
fell out of favor due to devastating visual complications
2) Other specialties, such as orthopedists and neurosurgeons, had
analogous, severe complications with particulate steroids
3) Thromboembolic complications can be avoided by using non-particulate
steroids such as dexamethasone
4) To date, there has yet to be any significant attempt to evaluate the
safety and effectiveness of intranasal dexamethasone treatments
5) The otolaryngologists’ aversion to intranasal injection treatments
may not be evidence-based
