Abstract
A method of applying a topical numbing agent to a nasal cavity without sedating a patient may include inserting a catheter into a nostril of the patient, the catheter having a first bend that forms a first angle such that at least a portion of the catheter is non-linear. The method may also include guiding a distal end of the catheter into the nasal cavity using a computerized tomography (CT) system by aligning a distal end of the catheter with a first cavity portion of the nasal cavity using a projection of the catheter within the nasal cavity on a CT scan of the patient, and moving the catheter within the nasal cavity while dynamically displaying the projection of the catheter by the CT system relative to the nasal cavity. The method may further include dispensing the topical numbing agent through the catheter into the first cavity portion.
