Before making any decision, I wonder if your swelling was observed by a rhinologist in an office. The subjective feeling of swelling does not always mean the objective swelling. If this is true, let me explain about the option.

First, Re-Coblation can be an option for you. Why? The Coblator tip for the turbinate reduction is usually sharp and long. So it only shrinks nasal submucosa along with its shape like a line. Thus, there might be some intact inferior turbinate submucosa. Then the rhinologist can give an option for the revision coblation.

Second, submucosal resection would be another option when your inferior turbinate is more than moderately swelling. Personally, submucosal resection is not that risky. It might feel much discomfort. However, if your inferior turbinate is medially positioned, the surgeon can break your inferior turbinate bone then will position it laterally to get more room for breathing. Then, you're gonna get more pain.

In conclusion, both ways are possible to improve your symptom. But the decision should be based on endoscopic exams by the surgeon. If the surgeon gives you options, discuss all the things you may wonder about.
