Treatment of postoperative frontal saphenous oedema with budesonide suspension in the low forward head position. Oedema often occurs in the postoperative cavity after nasal endoscopic surgery, and the use of local hormones is the main method to control the oedema. The traditional method of using nasal spray hormones is generally difficult to reach the frontal saphenous fossa area, which is the most important location for oedema and recurrence. How to do it: stand (or lie on your back or kneel on the floor) with your head tilted forward and the top of your head facing the floor so that your nostrils are as vertical as possible, and put half of the medication (pramipexole) inhaled into the syringe or plastic bottle into one nostril and hold it for 5 to 10 minutes.
