The maxillary (or second division) nerve block is an effective method of achieving profound anesthesia of a hemimaxilla. This block can be used for procedures involving the maxillary sinus, including the maxillary sinus elevation procedure. The purpose of this study was to evaluate a computer-controlled anesthetic delivery system (Wand) for maxillary nerve block injection to attain maxillary sinus anesthesia for sinus floor elevation procedure. ⋯ The Wand appears to offer a number of advantages over the hand-held syringe when the greater palatine block technique for the maxillary nerve block is used. It is suggested that, when indicated, and with the required knowledge and respect for the associated anatomy, this technique should be considered with greater ease and more confidence.
