Both are O.K., my preference is sedation.

Advantages of general anesthesia:

• No pain with injections
• Ease for the surgeon

Disadvantages of general anesthesia:

• Higher risk (arguably)
• Higher cost in some practices where an in office procedure can be done with sedation but not general anesthesia
• More nausea associated with general anesthesia
• Blood pressure can increase on waking which can lead to hematomas

The procedure can be done either way and I have and do both.  My preference is excellent local anesthesia with sedation for the reasons discussed above.
