@narelled23 The Flexible Laryngoscope is one of the most valuable tools the ENT has for evaluating issues in the throat. After many years of "stuttering" through diagnoses and issues, with the scope the doc was able to rule out any significant reflux, any physical obstruction, and find that vocal chord dysfunction was the cause of my choking episodes and vocal issues.
Our clinic uses disposable tubing to manage the slight infection risks, and the probe used for tissue sampling came straight out of the bag in which it was sealed after sterilization via autoclave.
It was not fun having my throat numbed, but far less invasive then a full endoscopy, with no prep (fasting, etc) required.

If the doctor takes proper precautions, the infection risk should be very small, and the ability to find a proper diagnosis is quite good.
