Dr. Kandula is no stranger to sinus issues.

After breaking his nose twice early in his life, he had traditional sinus surgery in 2011.

In 2016, Dr. Kandula noticed some deterioration from his first sinus surgery, so he underwent in office balloon sinuplasty and turbinate reduction. It was captured on video while Dr. Kandula narrated the entire procedure.

Sublingual (under-the-tongue) drops/tablets

sublingualdropsThe ADVENT Sinus and Allergy Center is one of only a few practices in Wisconsin to offer allergy sufferers allergy drops as an alternative to allergy shots. The antigens used in the allergy drops are the same FDA-approved antigens used in allergy shots, but they’re far more convenient, typically cost less, and require fewer clinic visits than allergy shots.
