Like any procedure problems can occur. The endoscopic brow lift is no exception. The problems that do occur happen approximately one percent of the time. Your individual reviewing of the brow lift procedure should reveal low complication rates with a high acceptance rate. Of course, counseling with your doctor should eliminate some of the risks.
Since this procedure can be completed under local anesthesia and/or general anesthesia you will have some recovery time either at home or in the hospital. Can you be conscious for the procedure? That will be a discussion during your initial consultation. If so you probably will be aware of the sensations like tugging and pulling associated with it, and for most people that might not be unacceptable. Being put to sleep by IV sedation would be the choice for most people including your physician, unless he sees otherwise. As always there is an inherent risk associated with any anesthesia, if any symptoms occur before or after your surgery your doctor should be notified. Stress and surgery go hand in hand.
Although the endoscopic technique is less traumatizing than the coronal lift, care should be taken when visualizing around the nerves and cutting around the hairline, nerve damage or minor hair loss may occur. The surgeons experience may be a factor. Irregularities of the forehead surface afterwards have been reported but may be rare occurrences. Swelling, pain and minor bruising are considered a result of the procedure more than a problem. A few days of rest and maybe some ice packs will reduce the pain and swelling along with some pain medication suggested by your physician. There may be a possibility of numbness, but should subside with time. In rare cases numbness may be permanent. Analyze your symmetry, make sure your eyebrows are even, if not, let your plastic surgeon know and he should be able to fix these types of problems.
Longevity of an endoscopic brow lift varies but on the average they last about 10 years and some patients will last a lifetime. The health of the patient generally may determine the lasting effects. Factors such as smoking and how well you treat your body physically and internally may also have a role.
