Anaesthesia of the tympanic membrane: Comparison of EMLA cream and iontophoresis

Abstract

The authors undertook a study to evaluate the effectiveness of two methods for providing local anaesthesia of the tympanic membrane for the purpose of inserting a grommet. The methods compared were the application of EMLA (Eutectic Mixture of Local Anaesthetics) cream and the use of iontophoresis. Both methods seem to provide a satisfactory level of local anaesthesia. It was felt that where multiple procedures were to be performed in one outpatient session the use of EMLA cream might be a more efficient technique.
