Intraoral Blocks for Facial Anesthesia: A Multimedia Instructional Tool

Publication ID Published Volume
1780 January 21, 2010 6


This is an interactive module created for medical students and residents in emergency medicine, dermatology and plastic/cosmetic surgery. On the home page the user may choose one of three intraoral nerve blocks, the infraorbital, mental or buccal. Each of the three intraoral nerve blocks has its own page on which the user may see a narrated video of the nerve block being given on a patient and on a skull. These videos walk the user through the proper technique for the injection.

In addition, the distribution of the nerve anesthetized is described and the user may scroll over an illustration of the face to light up the area of the face anesthetized by that particular nerve block. This project was designed to provide medical students and residents with options in anesthetizing the faces of their patients. Intraoral nerve blocks are easy to administer, relatively painless and are of long duration because the anesthetic solution is deposited very near the nerve exit point from the skull. This may provide more comfortable anesthesia for patients and enhance patient cooperation leading to better clinical outcomes.

This project is really about enhancing patient care. It is significant because it provides an easy to use educational tool that delivers the basics of administering intraoral blocks to obtain facial anesthesia. Using intraoral blocks for facial anesthesia has several benefits including relatively painless injections, longer duration and more profound anesthesia. When a physician can provide a more comfortable injection that provides longer lasting and more profound anesthesia, the patient is happier and the physician can perform optimally with superior clinical outcomes.

Educational Objectives

  1. To be able to review the nerve distribution patterns of the mental, infraorbital and buccal nerves relevant to utilizing intraoral blocks of these nerves for successful and profound facial anesthesia.
  2. To be able to describe the facial areas anesthetized by the mental, infraorbital and buccal nerve blocks.
  3. To be able to demonstrate techniques and provide detailed instructions for the mental, infraorbital and buccal nerve blocks.
