| Name | PDO Threads (Polydioxanone Threads) |
| Uses | Minimally invasive procedure using dissolvable PDO threads to lift and tighten sagging skin, improve skin texture, and stimulate collagen production. |
| Route Of Administration | Subdermal insertion of PDO threads using a fine cannula or needle. |
| Frequency Of Use | Typically performed once, with follow-up treatments every 12-18 months as needed. |
| Concentration(s) | PDO thread types vary based on treatment goals: - **Mono Threads**: Skin tightening and collagen stimulation - **Cog Threads**: Lifting effect for sagging skin - **Screw Threads**: Volume restoration and skin elasticity enhancement |
| Maximum Dosage (Day, Wk) | One treatment per session; number of threads used depends on the treatment area and patient anatomy. |
| Contraindications | Pregnancy, breastfeeding, active skin infections, history of keloid scarring, autoimmune diseases, bleeding disorders, recent dermal filler treatment in the same area (within 2 weeks), or hypersensitivity to PDO material. |
| Possible Side Effects | Mild swelling, bruising, tenderness, temporary skin dimpling, asymmetry, or rare risk of infection or thread extrusion. |
| Compatibility With Other Treatments/Drugs | Safe to combine with PRP, microneedling, and neurotoxin injections. Avoid aggressive facial massages, deep chemical peels, or laser treatments in the treated area for 2-4 weeks post-procedure. |
| Allergies | Assess for hypersensitivity to PDO thread material or local anesthetics used during the procedure. |
| Administration Time | 45-60 minutes per session, including numbing time and thread insertion. |
| Dosing/Settings | Standard PDO thread placement: - **Number of Threads**: 2-10 per treatment area - **Insertion Depth**: Subdermal layer - **Lifting Techniques**: Parallel placement, cross-hatching, or mesh patterns depending on patient needs. |
| Test Spot Requirement | Not required; however, first-time patients should start with a conservative number of threads to assess tolerance. |
| Pre-Treatment Guidelines | - Avoid NSAIDs, anticoagulants, alcohol, and blood-thinning supplements (e.g., fish oil, vitamin E) for 5-7 days before treatment. - Cleanse the skin thoroughly before the procedure. - Use a topical or local anesthetic to minimize discomfort. - Mark the treatment area based on the lifting or tightening goals. |
| Provider Clearance Guidelines | - Ensure the patient meets all clearance criteria before treatment. - If the patient has a history of facial trauma, recent surgery, or uncontrolled medical conditions, consult with a specialist before proceeding. - Document all clearance decisions in the patient’s medical record. |
| Pre-Treatment Screening Workflow | - Does the patient have a history of keloid formation? (If YES, proceed with caution and document risk counseling) - Is the patient on blood thinners? (If YES, consult before proceeding) - Has the patient recently had filler in the treatment area? (If YES, delay PDO treatment for at least 2 weeks) - Is the patient pregnant or breastfeeding? (If YES, contraindicated) |
| What To Do If Adverse Reaction Occurs | - **Bruising or swelling**: Apply cold compress and recommend arnica gel. - **Persistent tenderness or asymmetry**: Monitor and reassess after 2 weeks; consider manual adjustment if necessary. - **Infection (rare)**: If suspected, swab for culture and start empirical antibiotic therapy. - **Thread extrusion**: Trim exposed thread if visible and ensure proper healing. |
| Clinic Implementation Guidelines | - Confirm all consents are signed before treatment. - Ensure aseptic technique during PDO thread insertion. - Use proper cannula or needle placement techniques to minimize trauma and enhance results. - Conduct post-treatment follow-up within 2-4 weeks. |
| Photographic Documentation Protocol | - Take pre-treatment photos from standardized angles (front, side, and close-up views). - Take post-treatment photos immediately after the procedure and at the 4-week follow-up. - Store images securely in the patient’s medical record. |
| Post-Treatment Care | - Avoid excessive facial movements, strenuous exercise, or sleeping on the treated area for 48 hours. - Do not manipulate or massage the treated area for at least 2 weeks. - Use cold compresses for swelling and over-the-counter pain relievers if needed. - Mild tenderness and tightness may persist for up to 2 weeks. |
| Additional Documentation Requirements | - Signed informed consent detailing risks, benefits, and post-care instructions. - Treatment log including number and type of PDO threads used, placement technique, and patient response. - Post-treatment care instructions provided and documented. |
