After surgery, it is common for the resorbable wire used to close the skin to disappear naturally over time. Yet, it happens that a resorbable wire stays under the skin well beyond the expected period, raising concerns and issues. We decided to enlighten you on this phenomenon by addressing the key points:
- What is a resorbable wire and how does its degradation work?
- Potential causes that explain the persistence of the yarn under the skin
- The expected resorption time by wire type and individual factors
- Risks associated with a wire that does not disappear as expected
- Existing medical options to deal with this situation in an appropriate manner
Understanding these aspects will allow you to approach healing with more serenity and know how to recognize signs that require special vigilance.
Function and specificities of the resorbable wire under the skin
The resorbable wire is a masterpiece for surgeons in managing internal sutures or certain skin closures. Unlike non-resorbable wires, it gradually degrades through biochemical interaction with the body. These wires are designed to limit a second intervention, thus facilitating recovery.
The composition plays a key role: the yarns are frequently made from polyglycolic acid, polylactic acid or similar materials that decompose into non-toxic molecules, eliminated by the natural processes of the body. This mechanism promotes healing itself, limiting excessive inflammation and the risk of infection.
These yarns are used in a variety of fields, ranging from cosmetic surgery to orthopaedic surgery and gynaecological surgery. For example, during muscle repair or subcutaneous closure, these threads provide good tissue tension without leaving any visible external trace. In some areas of the face, resorbable tensor threads also allow a medical lift, their lasting effect can spread up to 24 months.
Their main advantage comes from the reduction of complications often associated with manual withdrawal: less rooting of bacteria, reduction of post-operative pain, and an improved aesthetic thanks to the gradual disappearance of the suture.
It is essential to understand that these yarns are very varied, and the degradation times depend in particular on their chemical nature and use.
Why the resorbable wire can stay under the skin longer: major causes
A resorbable wire that persists under the skin is not a systematic anomaly, but several factors can slow down resorption:
- The type and composition of the wire : Some wires are designed to degrade quickly, such as fast Vicryl in 7 to 14 days, while others, such as PDS, are made to last up to six months or longer. The yarns used in cosmetic surgery can even remain visible for up to 24 months.
- The biological reaction of the body : The creation of scar tissue around the wire can create a mechanical barrier preventing its assimilation. In some cases, the body encapsulates the wire in a small fibrous shell, insulating the material of the enzymes necessary for its dissolution.
- Initial poor settlement : A yarn placed under excessive tension or badly buried in the tissues may have difficulty in naturally degrade. This can occur, for example, if the surgical area undergoes frequent movement or pressure.
- Personal health factors : Diabetes, vitamin or protein deficiency, and some autoimmune diseases directly impact your body's enzyme capabilities. Tobacco also plays an important negative role in reducing local vascularization, delaying healing and deterioration of the yarn.
- Post-operative complications : Chronic infection or inflammation around the suture site may hinder the normal recovery and resorption process.
For example, in a recent study in 2024, 12% of patients with abdominal surgery had a resorbable wire that remained visible to control six months after surgery, often associated with a moderate local inflammatory reaction.
These causes are not isolated and can be combined. A rapid and adapted management will depend on a good recognition of these factors.
Length of resorption of the yarn under the skin: what should be known?
The classic time for a resorbable wire to disappear varies according to several criteria that we will detail for your understanding. The table below provides a summary of the average lead times according to the most commonly used yarn types:
| Type of wire | Average duration of resorption | Common use |
|---|---|---|
| Quick Vicryl | 7-14 days | Surface sutures, light aesthetic surgery |
| Vicryl standard | 60 to 90 days | Deep internal fabrics |
| Monocryl | 90 to 120 days | Subcutaneous sutures, plastic surgery |
| PDS | Up to 180 days (6 months) | Tissues with slow healing (tendons, aponeurosis) |
| Plastic tensor yarn | 12 to 24 months | Medical facelift |
Many patients question when the wire persists beyond these deadlines. It should be noted that these figures correspond to statistical averages and that individual metabolism, area treated and overall health status influence the rate of degradation.
A resorbable wire placed in a highly vascularized area, such as the face, will often eliminate it more quickly than in a less well irrigated area, such as the Achilles tendon. Similarly, well-nourished non-smokers have a very different healing and assimilation capacity than those with metabolic disorders.
In case of a scar where the yarn seems to persist for a long time, a specialized consultation provides precise answers and can help avoid possible complications.
Risks, complications and reactions to be monitored around a resorbable wire under the skin
A resorbable wire that does not degrade as expected can cause various complications, which should be detected and helped to prevent:
- Persistent inflammation: Redness, warmth and local oedema that do not disappear may indicate a chronic inflammatory response to the thread.
- Infection: The presence of purulent discharge, pus, with or without fever, is a sign of infection not to be ignored.
- Allergic reaction: Although rare, sensitivity to wire material can trigger pruritus, itching and extended redness.
- Nodule or granuloma formation: The body can encapsulate the thread, creating a palpable mass under the skin that can become aesthetically or physically annoying.
- Wire migrations: In some cases, the wire may come out or move, requiring rapid extraction.
These topical complications require special attention as they directly influence the quality of healing and the patient's comfort. Regular monitoring is essential to prevent these phenomena.
For example, patients followed after lifting with resorbable wires showed an incidence of prolonged local inflammation in 8% of cases, treated effectively with anti-inflammatory drugs and, if necessary, surgical withdrawal.
Medical solutions and driving to stand against a resorbable wire left under the skin
If the yarn persists under the skin and causes annoying symptoms, several treatment options can be considered depending on the severity of the case:
| Treatment option | Description | When to focus on it |
|---|---|---|
| Monitoring | Regular follow-up without immediate intervention, without inflammation or major infection | Stable position, non-inconvenient thread and no pain |
| Manual withdrawal | Extraction of yarn under local anaesthesia, carried out in consultation | Exposed wire, localized discomfort or pain, moderate inflammation |
| Antibiotic medicines | Prescribed in case of proven infection to control bacterial proliferation | Clear infectious signs, pus, fever |
| Surgery | Intervention to remove a wire deeply anchored or migrated, under local or general anesthesia | Severe complications, failure of other treatments |
Good communication with your medical team is essential to define a strategy adapted to your situation. These treatments are in the vast majority of cases simple and effective, allowing to quickly restore comfort.
Personally and preventively, we recommend that measures be taken to promote healing:
- Avoid physical activities that intensively solicit the area operated for at least 6 weeks
- Maintain a balanced diet rich in vitamins C and zinc
- Do not smoke to optimize blood irrigation and healing
- Carefully monitor signs of inflammation or post-operative infection
- Quickly check as soon as there are anomalies on the scar
These simple gestures promote better resorption of the wire and healthy healing without complications.
