ABSTRACT
The esophageal effect of topical anesthetics applied to the nasopharynx was evaluated. Eight healthy volunteers underwent an esophageal motility study after each of the following: no anesthesia, 5% cocaine solution applied to the nasopharynx, and 20% benzocaine spray applied to the pharynx. Upper esophageal sphincter relaxation was prolonged after use of the 5% cocaine solution. No other significant effects on esophageal motility or pressures were noted.
