The endoscopic middle meatal maxillary antrostomy is one of the most commonly performed endoscopic procedures. Because of the intimate relation of the orbit to the maxillary sinus, such procedure carries the possibility of major orbital complications. Accordingly, we describe a manoeuvre that helps confirm proper placement of the instruments within the maxillary sinus during surgery, obviating orbital insult.
