Will a full tummy tuck be enough or do I need an extended tummy tuck? (Photo)

Based on your pictures, your abdomen displays significant dimpling and skin irregularities. You are likely an excellent candidate for a full tummy tuck with muscle plication. This procedure removes excess skin and fat as well as tightens your abdominal muscles to give the appearance of a flatter abdomen.
If liposuction is desired, it is best to wait 3-6 months after your first procedure as combining a tummy tuck with liposuction is not recommended as blood supply to the abdominal flap may be compromised by doing so. An in person or virtual consultation with a tummytuck specialist will provide you an accurate recommendation and pricing.

The skin excess does extend beyond your hip bones so in my opinion an extended tummy tuck would give you the best results.

Hello and thank you for your question. First off, congratulations on losing all that weight, that's definitely a big accomplishment! Answering your last question, you should always try to maintain a healthy and active lifestyle, and be weight stable for at least 6-12 months prior to any body contouring procedure for best results. Aside from the obvious healthy benefits, this is because weight gain/loss is not a symmetric process, and any asymmetries resulting from an additional 10 lbs weight loss can be corrected in your subsequent surgery to give the best possible aesthetic result.
From the pictures you have provided, you have striae (stretchmarks) present throughout your entire abdomen. This is associated with a moderate/severe amount of excess skin and subcutaneous fat present diffusely throughout your trunk and extending to the sides into your flanks. There are skin folds across your lower abdomen extending to your mid flanks, but evaluation of these is limited by your underwear. Based on all this, you would definitely benefit from an abdominoplasty (tummy tuck- includes muscle repair) and liposuction of at least your flanks to best help improve your abdominal/trunk contour.
The difference between a "standard" and "extended" tummy tuck is just how far your incision extends to the side, and this is based on how much excess skin and fat needs to be removed to produce an aesthetic contour. They are essentially the same procedure, so no need to be concerned here. Generally, every surgeon tries to keep their incisions as short as possible so they can be easier hidden, but the goal here is improved body contour at the expense of scars, so this is important to keep in mind throughout the process. Regarding the transverse lower abdominal scar, it should be well hidden within your bikini or underwear, and if you adhere to proper scar care and sun avoidance after surgery, it should eventually heal to be minimally noticeable.
Liposuction is a great adjunct which would definitely provide additional benefit, particularly to the contour of your flanks, and can be done at the same time as your tummy tuck procedure for the best possible single operation results. Some surgeons universally include this as a component of all their tummy tuck procedures, and some itemize it as a separate procedure.
With all that said, it is always difficult to provide tentative surgical recommendations, as there is only so much information to be gained from any photos and descriptions provided. I recommend for you to come see me or another plastic surgeon for a formal consultation to thoroughly discuss your surgical goals, undergo a formal examination, evaluate all your options (surgical and nonsurgical), and decide on the best procedure(s) for your specific case. I hope this helps!
Best wishes,
