1. A system for acquiring measurements of a patient's upper airway comprising: a stereovideoscope comprising a scope coupled to a flexible tubing and configured to be positioned within the patient's upper airway, said scope comprising a plurality of stereoscopic lenses configured to capture data indicative of a portion of the patient's upper airway, said flexible tubing comprising a biocompatible material; and a processing element in communication with said stereovideoscope and configured to generate an image indicative of a portion of the patient's upper airway based on the captured data in order to acquire at least one geometrical measurement indicative of the portion of the patient's upper airway and to determine a probability of the patient's response to a tongue-base treatment based on the at least one geometrical measurement.
