To correct the dog ears, does it require more cutting , extending my scar further? (photos)

Revision of the submental scar can be performed after about 6 months or so and the incision may need to be extended. The contours do tend to improve with time.  

Thank you for your question and congratulations on your surgery.  In regards to fixing dog ears it's typically a pretty simple procedure.  Yes it does require an incision but not necessarily causing the incision to be much longer.  I would suggest speaking with your surgeon and following their recommendations.  Best of luck. 

Hello and thank you for your recent photos and question.  I would recommend waiting to you reach 6-12 to do any revisions as swelling can change the appearance of the end result.  Best of luck!

Dear Caring5209,
You are still in early postoperative period and there is a chance that your dog ears will improve with time. Generally speaking, you can expect a bit longer scar if you require surgical excision. If you have any questions, I suggest you to consult your plastic surgeon.

Generally speaking, revisional surgery should be delayed until adequately healed and stabilized. This point (while different for everyone)  is typically reached by 6 months post op.
With regards to your specific question, all dog ear excisions require scar extension posteriorly. How far back they extend is dependent upon the size of the dog ear. They can also be reduced via liposuction in conjunction with a more limited excision.Ultimately, I would allow for 6 months of healing (an additional 3 in your case) before considering further revision.
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

You are still early in the healing process and what you are seeing may not be your final results yet. The best course of action would be to have more patience and wait for about 6 months to fully heal, and only by then will you be able to conclude your results.

Hello and thank you for your question and photo's.  Yes, the scar does get extended to remove the dog ear, you may have needed an upper body lift where the scar goes all the way around the back and breasts.  

Hi and welcome to our forum!A dog ear represents a puckering of the skin at the incision terminations, occurring after skin closure. It may occur if the angle of skin excision segment is too great, elevating the base of the angle. Small dog ears will flatten and soften over a period of 6-12 months after surgery, while larger ones require surgical re-excision, extending the scar slightly further. The procedure is usually performed under a local anesthetic and is relatively minor.15% of cosmetic procedures require a secondary touchup.Maintain followup with your plastic surgeon.Best wishes...

Given that you are only three months out of surgery, I would not be surprised if the appearance of the "dog ears" improve over the course of the next several months (even up to one year and beyond). 
Generally, if in the longer term, there is redundant skin/tissue at the end of incision lines present (AKA dog ears)  additional skin excision may be necessary to improve contour in the area. This usually results in some extension of the scar .
 I hope this helps.
