Study type | Interventional |
The purpose of this study is to determine the normal distribution of nasal tissue cathelicidin antimicrobial peptides (cAMP) levels in subjects with normal smell and subjects with smell dysfunction. The investigators will also look at the effect of nasal saline irrigation on olfaction and cAMP levels and if nasal irrigation is capable of harvesting olfactory cilia. The investigators hypothesize that nasal saline will have no effect on olfaction and will be inadequate to harvest olfactory cilia.
