The nasal turbinates are bony structures covered by a mucous membrane lining the inside of the nose. There are 3-4 turbinates on each side of the nose (inferior, middle, superior, and sometimes supreme). Generally, the inferior turbinate is the most common of these to contribute to nasal obstruction as the majority of nasal airflow is through the inferior part of the nose. The turbinates will swell in response to inflammation, which is often caused by nasal allergies. The nasal obstruction related to enlarged turbinates tends to alternate from side to side as part of the nasal cycle. This swelling may respond to a nasal steroid spray (like Flonase, Nasonex, etc) used on a daily basis over the course of 4-6 weeks, but many times, the turbinates remain enlarged and continue to cause nasal obstruction despite medical treatment. Many patients also have nasal obstruction caused by a deviated septum, which will not respond to a nasal steroid spray or any other nasal decongestant because this is a fixed obstruction of bone or cartilage. While it is very common to shrink the turbinates at the time of septoplasty, your surgeon should perform a thorough history and physical exam to determine which procedures would benefit you the most.
