How is a dog ear revision performed?

You are correct...most dog ears require a slight extension of the original incision.  They can usually be reduced a lot, and there is also the chance of raising or lowering the ends of the incision if you like.

Dog-ears are excess skin and fat at the edge of the incision. Many dog-ears resolve on their own, however, if the dog-ear has not disappeared it may be a minimal to surgical incision. If the dog-ear is quite “large” you may require general anesthesia. So if a dog-ear is large or in a complex area. If the dog-ear is small it may require just a small in office procedure. The area is usually locally anesthetist and the area is made sterile then using a scalpel or curved scissors the excess dog is tented upward. A triangular area of skin and fat is excised on each side of the dog-ear. Then layers of suture are places to re-approximate the skin. Typically dog-ears should heal in 10-14 days depending on the size of the dog-ear a drain may need to be inserted.

Hello, revision of the dog ear can be done in the office setting using local numbing medication. Unfortunately, to treat the dog ear, it usually involves lengthening the incision in some manner. The incision does not have to be extended in a strait direction...it can often be curved or routed in a different direction...but it most likely will be longer.  Sorry.
