Plication surgery is any procedure in which a surgeon folds tissue back onto itself and secures the fold with sutures, tightening or reshaping a structure without removing it. The word comes from the Latin “plicare,” meaning to fold. Because no tissue is excised, plication tends to preserve blood supply and, in some cases, can even be reversed. The technique appears across a remarkable number of medical specialties, from facelifts and weight-loss procedures to eye muscle corrections and heart valve repairs.
How Folding Differs from Cutting
Most traditional surgical tightening involves cutting away excess tissue and reattaching what remains. A resection of an eye muscle, for instance, removes a measured strip of muscle to shorten it. Plication achieves the same shortening by folding the muscle onto itself and stitching the fold in place. The practical upside is that the tissue stays intact. Blood vessels running through the area are less likely to be damaged, healing can be faster, and in certain procedures the fold can be released later if the result needs adjustment. A randomized trial comparing plication to resection in eye-muscle surgery found that plication was similarly effective while being less traumatic, quicker, and potentially reversible.
This folding principle scales up and down. A plastic surgeon plicating the connective tissue layer beneath facial skin is working on a thin, delicate sheet. A bariatric surgeon folding the stomach wall inward to shrink its capacity is handling a thick, muscular organ. The sutures, the instruments, and the access approach change, but the underlying logic stays the same: create a controlled fold, anchor it with stitches, and let the new geometry do the work.
Facial Rejuvenation and Facelifts
One of the most common cosmetic uses of plication involves the SMAS, a fibrous layer that sits between the skin and the deeper muscles of the face. As people age, this layer stretches and sags. During a SMAS plication facelift, the surgeon identifies the point of greatest laxity, grasps that tissue with forceps, and places a buried suture that advances the loose portion toward the firmer tissue above it. The fold is then reinforced with additional interrupted sutures along the plication line.1Facial Plastic Surgery Clinics of North America. Millennial Facelifts: The Endoscopic Approach Makes Them a Reality The result lifts the midface and jawline without removing the SMAS tissue itself.
Recovery from SMAS plication deserves some attention. Folding the platysma muscle in the neck, which is often done alongside the facial SMAS work, raises venous pressure in the face and can increase postoperative swelling. Research on post-facelift recovery found that overly tight platysma plication combined with elastic bandaging amplified facial congestion, and that surgeons could minimize swelling by avoiding excessively tight folds and relying on aspiration drainage rather than compressive dressings.2Aesthetic Plastic Surgery. Face lift postoperative recovery This is a useful reminder that plication, while less invasive than excision, still has real mechanical consequences on surrounding tissue.
Gastric Plication for Weight Loss
Gastric plication takes the folding concept to the stomach. Instead of stapling away a large portion of the stomach the way a sleeve gastrectomy does, the surgeon folds the stomach wall inward and sutures it in place, creating a large internal fold that shrinks how much the stomach can hold. Two main approaches exist. In anterior plication, the front wall of the stomach is folded inward from top to bottom using two rows of running sutures, and the greater and lesser curvatures are brought together. In greater curvature plication, the blood vessels along the outer curve are divided first, and the greater curvature is folded inward with two suture lines.3PubMed. Laparoscopic gastric plication for treatment of severe obesity
The appeal of gastric plication is that no stomach tissue is removed and no staple line exists to leak, which is one of the most feared complications of sleeve gastrectomy. The procedure is also potentially reversible: if the sutures are taken down, the stomach returns to its original shape. In practice, though, how gastric plication compares to sleeve gastrectomy is mixed. One trial following patients for a year found that BMI dropped similarly in both groups and that plication patients actually had fewer readmissions, though one plication patient died of a pulmonary blood clot.4PubMed. Comparison of Short-Term Effectiveness and Postoperative Complications: Laparoscopic Gastric Plication vs Laparoscopic Sleeve Gastrectomy Another study found that sleeve gastrectomy patients had lower BMI at follow-up, while plication patients had shorter hospital stays, with complication rates similar between the groups.5PubMed Central. Comparison of laparoscopic sleeve gastrectomy and laparoscopic gastric plication: One year follow-up results
A systematic review and meta-analysis pooling multiple studies found that sleeve gastrectomy produced more sustained weight loss over time and had a lower overall complication rate, while the two procedures did not differ meaningfully in hospital stay, operative time, reoperation rate, or cost.6PubMed Central. Laparoscopic Gastric Plication versus Laparoscopic Sleeve Gastrectomy: An Up-to-Date Systematic Review and Meta-Analysis Gastric plication has not displaced sleeve gastrectomy in most surgical practices, but it remains an option in settings where reversibility or the absence of a staple line matters to the patient or surgeon.
Correcting Penile Curvature in Peyronie’s Disease
Peyronie’s disease causes fibrous scar tissue, called plaque, to develop inside the penis, leading to curvature that can make intercourse painful or impossible. Penile plication straightens the penis by placing sutures on the side opposite the plaque, shortening the longer side to match the shorter, curved side. It has become the preferred surgical technique for this condition because of its safety, efficiency, and high success rate.7PubMed Central. Peyronie’s penile plication
Plication is best suited for men who still have good erections and whose curvature is moderate. Guidelines generally suggest it for curvature under about 60 degrees in men with a penis longer than 13 centimeters, since the procedure does shorten the penis somewhat, with predicted shortening of up to about 20 percent.8International Journal of Impotence Research. Plication techniques in Peyronie’s disease: new developments For men with more severe curvature or significant erectile dysfunction, surgeons typically turn to grafting procedures or penile implants instead.9PubMed Central. Surgery for Peyronie’s disease
Technique refinements over the past decade have expanded who can benefit. Newer approaches avoid fully degloving the penis by using a smaller penoscrotal incision, reducing surgical trauma. Surgeons have also developed ways to bury suture knots beneath the tissue surface to prevent the palpable lumps that some patients find uncomfortable, and some now thin or incise the plaque itself to reduce shortening.8International Journal of Impotence Research.

Eye Muscle and Eyelid Corrections
Plication shows up in two distinct areas of eye surgery: correcting misaligned eyes and lifting droopy eyelids.
Strabismus, or crossed eyes, happens when the muscles that control eye movement are imbalanced. The traditional fix for a weak muscle is resection, which involves detaching the muscle from the eye, cutting a piece off, and reattaching the shorter muscle. Plication achieves the same tightening by folding the muscle-tendon unit back onto itself and suturing it to its original insertion point. No muscle is detached, no tissue is cut, and the blood supply running through the muscle stays intact. A randomized clinical trial found plication to be as effective as resection when combined with a loosening procedure on the opposing muscle, with the added benefits of being quicker and preserving the blood vessels that feed the front of the eye.10PubMed Central. Plication as an alternative to resection in horizontal strabismus: A randomized clinical trial Because the muscle is never detached, surgeons can theoretically reverse the procedure if the alignment turns out to be off.11JAMA Ophthalmology. Surgical Outcomes Following Rectus Muscle Plication: A Potentially Reversible, Vessel-Sparing Alternative to Resection
Eyelid ptosis, the medical term for a drooping upper lid, is a separate problem. It happens when the muscle or tendon responsible for lifting the lid weakens or stretches. Plication can tighten this mechanism without cutting anything away. In one large series, a plication of the deeper layer of the eyelid-lifting tendon achieved the target lid height and symmetry in about 95 percent of eyelids, with only around 5 percent of patients needing a revision.12PubMed Central. Mild to moderate blepharoptosis correction: Outcomes of levator aponeurosis posterior layer plication A modified technique folding both the tendon and the underlying smooth muscle together reported an overall success rate of about 88 percent.13Annals of Plastic Surgery. A Modified Technique Using Levator Aponeurosis–Müller Muscle–Reinforced Plication for Blepharoptosis Correction For patients who develop a drooping lid after cosmetic double-eyelid surgery, a plication approach through the inner lining of the lid can correct the asymmetry with minimal visible scarring.14PubMed.

Diaphragm Plication for Breathing Difficulty
The diaphragm is the dome-shaped muscle separating the chest from the abdomen, and it does most of the mechanical work of breathing. When one side of the diaphragm becomes paralyzed or abnormally elevated, it sags downward during inhalation instead of contracting, which crowds the lung on that side and makes breathing feel labored, especially when lying flat or exercising. Plication flattens the diaphragm by folding and suturing the floppy tissue so it can no longer balloon in the wrong direction. Whether the cause is nerve damage, a congenital defect, or an unexplained weakness, the surgical treatment is the same: reduce the dysfunctional sagging during inspiration.15The Annals of Thoracic Surgery. Diaphragm Plication for Eventration or Paralysis: A Review of the Literature
Minimally invasive approaches using video-assisted or robotic techniques have emerged as alternatives to open surgery, with similar effectiveness and less surgical trauma.15The Annals of Thoracic Surgery. Diaphragm Plication for Eventration or Paralysis: A Review of the Literature The results can be dramatic in the short term: a retrospective study found that lung function improved by roughly a quarter within six months after plication. However, from about the 18-month mark, lung function began to decline gradually, returning to preoperative levels by around the fourth year.16PubMed Central. Long-term efficacy of diaphragm plication on the pulmonary function of adult patients with diaphragm paralysis: a retrospective cohort study That finding suggests diaphragm plication provides meaningful but potentially time-limited relief, and patients should go in with realistic expectations about long-term durability.
Tightening Loose Shoulder Joints
Some people have shoulder joints that are unstable in multiple directions, a condition called multidirectional instability. The joint capsule, a thick fibrous envelope that wraps around the ball-and-socket joint, is too loose or stretchy, allowing the arm bone to shift around more than it should. This causes pain, a feeling of the shoulder slipping, and difficulty with overhead activities. Capsular plication folds the excess capsular tissue and sutures it to reduce the joint’s internal volume, effectively tightening the envelope.17Arthroscopy Techniques. Arthroscopic Capsular Plication for Multidirectional Shoulder Instability in Hypermobile Ehlers-Danlos Syndrome Patients
This procedure is typically done arthroscopically, through small incisions with a camera and instruments inside the joint. A study of capsular plication in patients with multidirectional instability, including those with a connective tissue disorder that makes joints hypermobile, found meaningful functional improvement and a low failure rate.18PubMed Central. Arthroscopic Capsular Plication Shows Low Failure Rates and Meaningful Functional Improvement in Multidirectional Shoulder Instability With and Without Hypermobile Ehlers-Danlos Syndrome A separate series of competitive swimmers who had failed non-surgical treatment and underwent capsular plication showed that while the procedure helped many return to competition, some could not get back to their pre-injury training volume, highlighting that even a well-executed plication has limits in athletes who place extreme demands on the shoulder.19PubMed Central.

Heart Valve, Abdominal Wall, and Pelvic Floor Repair
Plication is used in cardiac surgery to repair aortic valves that leak because one of the valve leaflets has prolapsed, or drooped, into the ventricle. By placing a plication suture along the free edge of the floppy leaflet, the surgeon shortens it just enough to restore proper closure. This approach is usually the first choice for cusp prolapse repair because it is straightforward and carries a lower risk of overcorrection compared to the alternative technique of resuspending the leaflet with a new suture line.20The Annals of Thoracic Surgery. Cusp Prolapse Repair in Trileaflet Aortic Valves: Free Margin Plication and Free Margin Resuspension Techniques
In the abdominal wall, plication is a central step in repairing rectus diastasis, the separation of the left and right abdominal muscles that commonly occurs after pregnancy. The surgeon folds the stretched connective tissue between the muscles and sutures it, pulling the muscle bellies back toward midline. This repair is often combined with body contouring procedures such as abdominoplasty, especially in patients with excess skin or soft tissue laxity.21PubMed Central. Abdominoplasty and rectus diastasis repair-a plastic surgeon’s perspective
The pelvic floor is another area where plication has a long history. Posterior vaginal wall prolapse, where the back wall of the vagina bulges forward due to weakened support, can be repaired by plicating the fascia underneath. A review of the evidence found that midline fascial plication offered strong anatomic correction and better functional outcomes than older techniques that relied on plicating the pelvic floor muscles themselves, which sometimes caused pain during intercourse.22International Urogynecology Journal. Surgical management of posterior vaginal wall prolapse: an evidence-based literature review
Why Suture Choice Matters
Because plication relies entirely on sutures to maintain a fold, the choice of suture material is not trivial. In procedures where the fold needs to be permanent, there is a natural instinct to use non-absorbable sutures that stay in the body indefinitely. But those permanent sutures can create problems of their own. A study of penile plication found that absorbable and non-absorbable sutures produced equally good straightening results, but patients who received non-absorbable sutures were far more likely to report bothersome lumps they could feel through the skin.23Urologia Internationalis. Absorbable versus Non-Absorbable Sutures in Plication Surgery for Penile Curvature: A Comparison of Outcomes That finding has pushed many surgeons toward absorbable sutures or toward techniques that bury knots deep within tissue where they are less likely to be felt.
Suture diameter introduces its own tradeoffs. Thicker sutures can handle more tension but tend to tear through tissue when loads are high, while thinner sutures distribute force more gently but are more likely to break under strain.24Frontiers in Surgery. Progress in tension-relieving suturing surgery: revolutionary surgical techniques and patient prognosis evaluation methods Surgeons match suture size to the tissue being plicated: delicate eyelid work calls for very fine thread, while abdominal wall plication uses heavier gauge. Getting this balance wrong in either direction raises the risk of the repair failing or the tissue being damaged by the suture itself.
When Plication Is Chosen Over Alternatives
Across all these specialties, plication tends to be favored in a few recurring situations. It is attractive when preserving the native tissue matters, such as in heart valve repair, where keeping the patient’s own valve avoids the need for blood thinners that come with mechanical replacements. It is preferred when reversibility is valuable, as in pediatric eye-muscle surgery, where growth may change alignment over time. And it is often the less invasive option when a structure needs to be tightened rather than replaced or removed, as in shoulder capsules or stretched abdominal walls.
The tradeoff is durability. Plication repairs depend on sutures holding tissue in an unnatural configuration, and biological tissue has a tendency to stretch back over time. The diaphragm plication data, where lung function gains faded by the fourth year, illustrates this clearly. Gastric plication faces a similar concern, as the stomach wall can gradually relax. When long-term durability is the top priority and the condition is severe, surgeons often lean toward more permanent options like excision, grafting, or implants. Plication sits in a sweet spot where the condition is moderate, the tissue is healthy enough to hold a fold, and the patient values a less destructive approach.
Candidates for plication surgery generally go through a careful selection process. In Peyronie’s disease, that means measuring curvature, assessing erectile function, and estimating how much length will be lost. In eye surgery, it means quantifying the degree of misalignment. In bariatric surgery, it means weighing the lower risk profile against the possibility of less dramatic or less durable weight loss. The specific criteria differ across specialties, but the shared question is always the same: is the tissue healthy and elastic enough to hold a fold, and will the expected benefit justify the limitations of a suture-dependent repair?
