There are two broad types of sutures used in surgery: absorbable and non-absorbable, and within each, the material, structure, and coating determine what happens on the table and long after the patient has gone home. Get the classification right, and wound closure becomes predictable. Get it wrong, and you’re looking at delayed healing, unwanted scarring, or a second visit you didn’t want.
Ask any surgeon what changed their approach to suturing early in their career, and most will tell you it wasn’t a textbook. It was a case that went slightly sideways because the suture material didn’t match the tissue. That’s really what this guide is about, not a dry rundown of suture classification, but a working reference for choosing between absorbable and non absorbable sutures for the right job, backed by what Aqmen Medtech actually manufactures.
Suture Classification: The Two Questions That Matter
Every suture, no matter the brand or the catalogue number, answers two questions that sit at the core of suture classification:
1. Does it get absorbed by the body (absorbable suture material), or does it stay (non absorbable sutures)?
2. Is it made of synthetic material or is it non-synthetic in nature?
Everything else, colour, coating, types of suture needles, tensile strength, sits downstream of these two decisions. Once you’re clear on absorbable versus non-absorbable and mono versus braided, picking the right one among the many types of sutures for a hernia repair versus an eye procedure stops being guesswork.
Absorbable Sutures: Built to Disappear on Schedule
Absorbable suture material is designed to break down naturally in tissue once its job of holding the wound together is done, so there’s no removal visit and no retained foreign material long-term. Within this category, you’ll typically work with:
Natural absorbable sutures:
Catgut, available as Plain (rapidly absorbed) or Chromic (treated with chromic salts to extend wound support), is one of the oldest naturally absorbable suture material options still used today. Aqmen’s AQgut® range is a twisted multifilament suture with no fraying, commonly used across GI, obstetric, gynaecological, general, and urological surgery, with roughly 21 days of wound support, making it a dependable choice among natural types of sutures in surgery.
Synthetic absorbable sutures:
This is where most modern absorbable suture material lives. Aqmen’s AQsolve® and Polysolve 910™ (Polyglactin-910, braided and coated) give around 28 days of wound support with excellent knot security, and are used across oral, eye, GI, obstetric, gynaecological, general, and plastic surgery. For faster turnover, AQfast® (Polyglactin-910, fast absorbable) supports superficial soft tissue closure over 14 days, with the added benefit of reduced pain and quicker resumption of normal activity for the patient. Polysolve+™ adds antibacterial triclosan to the same braided base for extra protection during the healing window.
Monofilament absorbable options:
Among monofilament types of sutures, AQmono® (Poliglecaprone 25) stands out as an absorbable suture material prized for minimal scarring and excellent cosmetic outcomes with predictable absorption over 21 days, making it a favourite for plastic, GI, gynaecological, general, and urological work. AQPDsyn® (Polydioxanone) goes further, offering 42 days of wound support with slow, predictable absorption, useful wherever tissue needs more time to regain strength among sutures used in surgery, from orthopaedic to abdominal procedures.
Non-Absorbable Sutures: Built to Stay the Course
Non absorbable sutures aren’t broken down by the body, so types of sutures either remain permanently or are physically removed once the wound has healed enough to hold on its own. They come into play when a wound needs long-term or permanent support, or where suture removal is straightforward, like skin closure.
AQlene® (Polypropylene, blue, monofilament) offers permanent wound support with high plasticity that accommodates wound edema, doesn’t adhere to tissue, and is easy to remove, making it a go-to for running or subcuticular skin closure.
AQbond® (Polyester, green and white, braided and coated) brings high tensile strength and a silicone coating for smooth knot sliding, commonly used in cardio and general surgery where a secure, permanent hold matters.
AQlon® (Polyamide 6 & 6/6, black, monofilament) is one of the most widely used sutures in cutaneous operations, valued for its elasticity and non-fraying finish.
AQsilk® (Silk, black, braided multifilament) is a natural non-absorbable option, soft and pliable enough for mucosal and intertriginous areas, and available in both non-sterile reels and pre-cut formats.
Between absorbable and non-absorbable sutures, the deciding factor usually comes down to how much time the tissue genuinely needs to heal, and whether a removal visit is realistic for that patient.
Types of Suture Needles: The Half of the Equation Nobody Talks About Enough
Suture material gets most of the attention, but the needle attached to it decides how cleanly that suture passes through tissue in the first place. Among the many types of sutures in surgery, the types of suture needles they’re paired with are grouped broadly by:
Point type: round-bodied (for soft, easily penetrated tissue like bowel or fascia), cutting and reverse-cutting (for tougher tissue like skin), and blunt-point (for friable organs like liver or kidney, where reducing puncture risk matters).
Curve: from straight needles to ⅜, ½, and ⅝ circle, chosen based on how much access the surgical site allows.
Attachment: swaged (needle and suture fused as one unit, standard in most modern packs) versus eyed needles, which are rarer today but still used in select settings.
Aqmen’s suture ranges, across both absorbable and non absorbable sutures, are supplied with needles matched to their surgical application, so the needle-suture combination is already validated for the procedure it’s built for, one less variable to think about mid-surgery.
How to Actually Choose Between the Options
When you’re weighing types of sutures in surgery, five questions tend to settle it:
Tissue type: Is it fascia, skin, mucosa, or a delicate vascular structure?
Healing timeline: Does the tissue need 14 days of support or 42?
Tension at the site: High-tension closures often lean non-absorbable or slower-absorbing options like polydioxanone.
Cosmetic outcome: Facial or visible skin closures favour monofilament, low-reactivity materials like poliglecaprone.
Infection risk: Sites with higher contamination risk benefit from antibacterial-coated options like Polysolve+™.
Why the Manufacturer Behind the Suture Matters
Not all suture companies in India follow the same rigour when it comes to types of sutures, and that gap shows up in consistency on the table, not just on paper. Aqmen Medtech runs every suture through checks at the pre-production, production, and post-production stages before it reaches an operating theatre, which is a big part of why the same batch performs the same way, every single time. If your OT has ever dealt with inconsistent knot security or unpredictable absorption from a supplier, that’s exactly the variability this kind of process-level quality control is meant to eliminate.
Every category above, absorbable and non-absorbable, natural and synthetic, mono and braided, exists because no single suture works for every wound. Getting familiar with the classification isn’t academic. It’s what makes the difference between a closure you don’t think about again and one you’re called back for. Talk to Aqmen for suture options matched to your caseload.
Frequently Asked Questions
Absorbable suture material breaks down naturally in the body over weeks, removing the need for a removal visit. Non absorbable sutures stay permanently or are removed once the wound has healed enough to hold on its own.
Among the types of sutures in surgery, monofilament absorbable options like Poliglecaprone 25 are commonly preferred for cosmetic closures, causing minimal tissue reaction and predictable absorption that helps reduce visible scarring on skin and facial procedures.
Suture needles vary by point (round-bodied, cutting, reverse-cutting, blunt), curve, and attachment (swaged or eyed). Understanding these types of suture needles helps match the right needle to tissue type and available surgical access.
It depends on the material used among sutures used in surgery. Fast absorbing options like Polyglactin-910 support wounds for about 14 days, while Polydioxanone can support tissue for up to 42 days.
Not always. Some non absorbable sutures, like polypropylene or polyester, are used for permanent internal support in cardiovascular procedures. Others placed on skin are typically removed once the wound has healed sufficiently.
