Do Enlarged Lower Turbinates Always Show Up on a CT Scan?

Depending on the views obtained, the turbinates do indeed show up on CT scan. However, recommendations to cauterize, infracture, or perform partial inferior turbinectomies or turbinoplasties are based on airway assessment, not JUST CT scan.

Reading a CT scan is something radiologists do as their specialty, but their focus (and report) may be based on identifying fracture, tumor, or other abnormality, and may not specifically address airway, which involves subjective as well as objective tests, observation, and recommendations.

It sounds as if you are having doubt as to the recommendations of your rhinoplasty consultant--if in doubt, seek consultation with one or more additional experts in rhinoplasty: ABPS-certified plastic surgeons with extensive experience in rhinoplasty, or board-certified ENT experts in rhinoplasty surgery.

BTW, it is usually not necessary to cauterize, infracture, AND perform partial turbinectomies, but choose which of these is necessary or advisable--not usually ALL of them! Best wishes!

No not always, CT scans are static cuts and if the angle of the cut is not perfect it may not show the area of the obstruction well.
