A review of my colleagues’ responses may give the casual RealSelf reader the wrong impression on this topic. In breaking with some of my more prolific RealSelf “2 lines or less” responders, I think this topic is important and deserves a proper explanation.
From the beginning of time, surgeons have used multiple ways of bringing cut tissues together, from using fire ants to bite and hold the tissues and then twisting their heads off (which would not go over well with PETA and current sterility regulations), to using rubber tree sap on strips to using silk, horse tail hairs or cotton strands to silver wires. Everything has been tried. In time, sutures (stitches) became divided into 2 large groups: very long lasting (Permanent) and Dissolving. Further divisions into single strand VS multiple strand (rope like) stitches help in categorizing stitches.
As Surgery evolved and the science of surgery has grown into multiple specialties, surgeons availed themselves of a certain suture for a certain job; picking the suture which provided the best duration of strength for the interval required for healing.
Simply put, a stitch is a foreign body (just like a pacemaker, breast implant, artificial lens, artificial hip, bullet, heart valve, etc). Some people tolerate them extremely well while others do not. As a result, in picking a specific suture, surgeons choose one whose duration and strength correspond to how long it will be needed before the body’s healing and scar tissue are sufficient to maintain the tissues or structure / implant in place. For example, when we stitch facial cuts, we universally clean the wounds and close them in several layers with dissolving sutures. Since there is no constant pull on the skin edges, we do not need to rely on long-lasting or permanent stitches. Similarly, in eye surgery where only a temporary hold is needed while the body is healing, permanent stitches are not needed and small dissolving stitches are commonly used (except for lenses). The heart and blood vessels pose different challenges. The heart beats 60 to 120 times a minute. The heart valves snap open and shut this many times until the valve degenerates and needs changing or your heart stops. In other words, non-stop action for the rest of your life. If a new heart valve was stitched with the best long lasting dissolving stitches, it would not take too many beats after the last stitch has dissolved for the valve to be blown away from the heart by the force of contraction. Similarly, all vessels (from the biggest in the body to coronary bypass grafts to those stitched together under the microscope as when fingers are put back on) are joined with permanent stitches to avoid their coming apart. The same applies to shoulder, hips and knee joints which experience large forces of tension and compression.
When it comes to abdominal hernia surgery, we almost always use permanent stitches because the human abdomen is under a significant amount of permanent tension. Using dissolving stitches in hernia surgery invariably results in recurrence of the bulging.
Which brings us to the topic of THE proper closure Tummy Tuck muscle repairs and the transverse wound. The old joke remains ; 2 Plastic surgeons in the room – 3 different opinions (at least). (And if allowed, our discussions resemble those seen in the British Parliament. Those who have seen it, will understand).
Tummy Tuck Surgery and Body Contouring after massive weight loss was influenced and advanced by one surgeon more than many others – Dr. Ted Lockwood of Kansas. Dr. Lockwood described the strength layer of the lower abdomen and the thigh – the SFS, which allows us to lift the thighs as part of a tummy tuck. He also described the High Lateral Tension Abdominoplasty, a very innovative tummy tuck method upon which many other techniques are based.
A concept known to ALL Plastic surgeons is that to obtain an attractive, narrow scar, tension on the (superficial) skin closure must be avoided by all means. Tension on the skin always results in wide, ugly scar. How then can we really pull the tummy skin and flatten it but avoid the tension being transmitted to the top layer of the skin? We use deeper stitches to do all the pulling along the deep layers allowing the superficial skin edges just “kiss” and put together without tension. The resulting scars are always nice. This principal is used in Facelift surgery and in Tummy Tuck surgery. IF I am to smooth the tummy, lift my patient’s thighs, smoothing them and the lower tummy, I put deep tension holding anchor stitches in the SFS layer. On this point, the vast majority of Plastic surgeons would agree.
The question comes, what happens to the superficial, visible scar when the deep stitches dissolve?
What do you think? What does your common sense tell you?
WHY would we need permanent stitches in the heart, in blood vessels, to anchor joints, but somehow the weight of the thighs can now only be supported by our scar tissue without pulling on the superficial skin? That is where Plastic surgeons disagree.
Having seen multiple previously beautiful, hairline thin Tummy Tuck scars widen months after surgery when the deep dissolving stitches went away and the weight of the lower aspect of the wound WAS transmitted to the scar, I am convinced that there IS a place for permanent stitches in the deep SFS layer in Tummy Tuck surgery. Dr. Lockwood thought so and passionately advocated the use of braided permanent stitches (Neurolon) in the deep layer. (The same stitch you appear to have by the way).
And now, for the sake of complete disclosure, the dirty secret. ALL stitches can spit. Both dissolving (Vicryl, PDS etc) and permanent. Long lasting dissolving stitches whose knots are often stiff can be very annoying to patients and once they are pushed close to the skin, they are extruded very much like the permanent stitch you wrote about. In both cases, the removal of the suture is followed by rapid healing.
The ONLY question you need to ask yourself and your surgeon – What is better FOR ME - a CHANCE of spitting one or more deep permanent stitches as a payment for a hairline scar and smooth tummy and thighs OR the slightly smaller chance of spitting long-lasting dissolving stitches (such as PDS) with a near certainty of tension-related, delayed scar widening?
I know which answer most of my patients would give.
Cheer up. As hard as this may be on you now it WILL get better.
