Can a deviated septum surgery affect allergies?

Helps the congestion: The nasal septum is the divider between the nostrils. No one is perfect, but some folks' bony septums can be significantly deviated from the midline (from birth or injury) adding to congestion from viruses or allergies. Correcting this deviation will alleviate this obstruction to a greater or lesser extent, help any sleep apnea, but the sneezing, itching, and running will still occur.
