To the Editor:
Navigation is now part of our daily life, whether flying a plane or driving a car. Going after a target blindly while a great localizing tool is available sounds irrational. It is like operating on a deep brain glioma without image guidance. While we have no control group, surgeons dealing with the lateral femoral cutaneous nerve (LFCN) are quite familiar with the difficulty it usually takes to find the nerve. I like this quote from Allen Maniker, “If you think it’s nerve, it’s probably not. Just as you are about to give up, you will find it. By the end of the case it all looks like a nerve.”1 Even in the most experienced hands, ultrasound (US) can help identify abnormalities such as duplicate nerves or nerves coursing lateral to the anterior superior iliac spine. I would like to emphasize that the time spent in the US suite is much less costly than the one spent in the operating room under anesthesia.
