In a recent publication1 a satisfactory technic for performing radical operations on the maxillary sinus under local anesthesia was described. It has been our custom to do practically all of our radical operations on the sinus by blocking the nerves with infiltration anesthesia, and experience has proved that operation on the frontal as well as on maxillary sinuses can be performed with this method of anesthesia.
It is a simple procedure to produce satisfactory narcosis for operation on the frontal sinus, which actually requires injection at only two sites. However, since it is distinctly advantageous to inject a solution of epinephrine into the region of the primary incision, we take advantage of this infiltration by using a weak solution of procaine hydrochloride as a carrier for the epinephrine. If this step is included, it constitutes a third and optional site of anesthetization.
