Clinical Breakthroughs Nyob rau hauv pob txuv thiab mob pob khaus kho nrog Microneedling

https://en.wikipedia.org/wiki/Microneedles

Scars yog cov imprints mus tas li ntawm kev raug mob tob tob. Kev nyuaj siab pob txuv nti thiab hypertrophic traumatic caws pliav cuam tshuam rau cov neeg mob tus kheej - kev ntseeg siab thiab kev puas siab puas ntsws zoo -. Cov txheej txheem ib txwm siv-laser resurfacing, tshuaj tev tawm, thiab kev phais tshem tawm- feem ntau ntsib kev txwv txog kev ua tau zoo, kev poob qis, lossis kev cuam tshuam tsis zoo.Microneedling omuaj kev nyab xeeb, zoo, thiab siv tau rau kev kho caws pliav.

Pob txuv nti, feem ntau ntawm daim tawv nqaij atrophic caws pliav, tshwm sim los ntawm collagen tsis txaus nyob rau hauv lub dermis. Lub ntsiab logic ntawm microneedling rau cov nti yog"ua txhaum los tsim."Cov koob lub cev sever abnormal fibrous septa tethering ntawm daim tawv nqaij, tso caws pliav ntaub so ntswg thaum ib txhij stimulating fibroblasts synthesize tshiab collagen los sau cov kev nyuaj siab. Kev xyaum kho mob dictates rab koob ntev raws li caws pliav qhov tob: 0.5-1.0 hli rau cov kab nrib pleb sab saum toj thiab 1.5-2.0 hli rau qhov tob tob hauv lub thawv. Kev sib tham yog ncua 4-6 lub lis piam sib nrug, feem ntau xav tau 3-6 kev kho mob.

Extensive clinical evidence supports this approach. A meta-analysis of 120 patients with moderate-to-severe acne scars showed that over 75% achieved >50% kev txhim kho tom qab plaub zaug, nrog qhov kev txaus siab nruab nrab ntawm 8.2/10. Qhov tseem ceeb, microneedling muaj qhov pheej hmoo tsawg dua ntawm post-inflammatory hyperpigmentation (PIH) piv rau ablative lasers. Hauv cov neeg Esxias, qhov tshwm sim PIH tsuas yog 5-10% nrog microneedling, piv rau 20-30% nrog cov laser fractional, tsim nws raws li qhov kev xav tau rau hom tawv nqaij tawv (Fitzpatrick IV-VI).

Rauhypertrophic nti thiab keloids, microneedling muaj qhov tshwj xeeb zoo. Cov caws pliav no yog tus cwj pwm los ntawm ntau dhau ntawm fibroblast proliferation thiab collagen tsub zuj zuj. Microneedling lub cev cuam tshuam cov pob khoom hnyav collagen thaum ua haujlwm rau kev tiv thaiv -fibrotic cov neeg ua haujlwm zoo li Triamcinolone lossis 5-Fluorouracil, ua tiav ob qho txiaj ntsig ntawm "kev cuam tshuam thiab kev tawm tsam." Cov kev tshawb fawb qhia tias kev sib txuas ntawm microneedling nrog kev txhaj tshuaj intralesional txo qis tus nqi rov qab mus rau ib feem peb ntawm qhov pom nrog kev txhaj tshuaj ib leeg, thaum txo qhov mob thiab poob qis.

Hauvkho mob caws pliav, microneedling txhim kho kev ntxhib los mos thiab dyschromia. Kev faib tawm melanocyte tsis sib xws feem ntau ua rau hyper- lossis hypopigmentation; microneedling txhawb nqa cov khoom sib xws ntawm cov khoom ci ci los yog txhawb nqa melanocyte tsiv teb tsaws los kho cov xim tsis sib haum. Tsis tas li ntawd, cov neocollagenesis txhawb nqa los ntawm microneedling ua kom zoo dua nrog cov txheej txheem ntawm daim tawv nqaij, ua rau cov caws pliav flatter thiab zoo nkauj dua qub.

Lub sijhawm zoo yog qhov tseem ceeb: lub qhov rais zoo tshaj plaws rau kev cuam tshuam yog 3-6 lub hlis tom qab- raug mob thaum lub caws pliav nyob rau hauv ib qho kev hloov kho tshiab. Thaum laus lawm, cov caws pliav yuav tsum tau ua ntau zaus, kev txhim kho tseem ceeb tseem ua tau. Nrog nws cov xwm txheej tsawg kawg nkaus, tsis tshua muaj kev pheej hmoo, thiab rov ua dua, microneedling tau dhau los ua lub hauv paus thev naus laus zis hauv kev tswj cov caws pliav.
