title: Endoscopic vocal fold injection using a 25-gauge butterfly needle.
abstract: OBJECTIVE
  To describe a useful technique for infiltrating a bulking agent using a butterfly needle, as part of a transoral endoscopic vocal fold medialisation procedure.
  
  
  METHODS
  This paper describes the procedure of grasping the needle with phonosurgery forceps and administering the injectate to the vocal fold through careful application of the syringe plunger via a length of rubber tubing from outside the mouth.
  
  
  RESULTS
  This procedure is performed routinely in our institution without complication. The advantages of this technique are discussed.
  
  
  CONCLUSIONS
  This is a safe and easy method of injecting into a vocal fold.
