Will ADM be Absorbed? How Long Does the Result Last?
Q：聽說真皮移植會被吸收，異體真皮填補能維持多久？
Q: I heard that dermal grafts get absorbed by the body. How long will the ADM (Acellular Dermal Matrix) results last?
A：薛醫師的專業解答：
這是一個非常專業的好問題。首先，我們要區分「暫時性填充」與「組織一體化」的差別。
- 吸收與穩定期： 在植入後的初期（約 1-3 個月），確實會有一部分水分或非結構性物質被身體自然吸收，這是正常的修復過程。
- 血管新生與一體化： 異體真皮最大的優點在於它的「支架特性」。約在 3-6 個月後，您身體的微血管與纖維母細胞會長入這個支架中。
- 半永久性的改善： 一旦您的組織與支架完成「一體化（Integration）」，它就變成了您皮膚結構的一部分。它不再是外來物，而是轉化為您真實的真皮組織。
結論：不同於幾個月就會消失的玻尿酸，異體真皮粉提供的是「半永久性」的體積支撐。雖然隨著年齡老化膠原蛋白仍會緩慢流失，但手術墊平的凹陷不會像填充物那樣完全被打回原形。
A: Dr. Hsueh’s Professional Answer:
This is an excellent and highly professional question. We must distinguish between “temporary filling” and “tissue integration.”
- Absorption and Stabilization: During the initial phase (approx. 1-3 months), a small portion of the volume—mainly fluid or non-structural components—will be naturally absorbed. This is a normal part of the healing process.
- Angiogenesis and Integration: The greatest advantage of ADM is its “scaffold” property. Between 3 to 6 months post-procedure, your body’s own microvessels and fibroblasts will grow into this scaffold.
- Semi-Permanent Improvement: Once your own tissue completes the “Integration” process with the scaffold, it becomes a permanent part of your skin structure. It is no longer a foreign filler but has transformed into your actual dermal tissue.
Conclusion: Unlike hyaluronic acid, which disappears within months, ADM provides “semi-permanent” volume support. While natural aging will eventually cause gradual collagen loss over years, the treated scars will not simply “deflate” back to their original state like synthetic fillers.
薛醫師的衛教小撇步 (Dr. Hsueh’s Pro-Tip):
我常跟病患說，這就像在貧瘠的土地（凹疤）上鋪設擋土牆與土方。前幾個月土石會稍微沉降壓實，但只要植被（血管）長進去後，這塊土地就穩固了。
I often tell my patients: it’s like building a retaining wall and adding soil to a barren slope (the scar). The soil may settle slightly in the first few months, but once the vegetation (blood vessels) takes root, the foundation becomes stable and permanent.
