How common are nerve damage, hitting growths, elevated blood pressure and weird responses to anesthesia during a neck lift?

In our practice, neck lift is performed in twilight anesthesia. Blood pressure is regulated before and in the course of surgery.Problems with anesthesia are very rare with this type of sedation/local anesthesia. Preoperative evaluation and clearance by patient's primary care physician is mandatory before surgery. No postoperative pain! All together, very safe and straight forward surgery in experienced hands. Good luck.

All the issues you mention are very uncommon. Best thing is to get a peroperative medical clearance from your doctor. Changes in BP and pain and anxiety can be easily managed during surgery.

You present many different issues which cannot be answered unless the chart was reviewed. Some can be expected, such as elevated blood pressure post op due to pain, which can happen to anyone. Other answers really depends on more information. What kind of nerve damage, motor or sensory, and where? What kind of growth, lipoma, lymph node, solid tumor growth and where? Blood pressure and weird response to anesthesia? What kind of anesthesia and was there an anesthesiologist? What was the weird reaction? More detailed information is needed.
