Kev lig kev cai, nws ntseeg tau hais tias lub sij hawm ntawm kev kho mob ntawm cov caws pliav yuav tsum yog 6 lub hlis mus rau 1 xyoo tom qab caws pliav yog paub tab thiab ruaj khov.Yog vim li cas yog tias tom qab cov caws pliav yog qhov paub tab thiab ruaj khov, nws cov ciam teb yog qhov tseeb, cov ntshav tau txo qis, thiab kev phais phais los ntshav tsawg dua.Cov txheej txheem uas tsis yog phais los tiv thaiv qhov caws pliav los "kho" nti (tiv thaiv cov caws pliav hyperplasia), xws li kev hnav khaub ncaws elastic kom txo cov ntshav ntawm cov caws pliav, kev txhaj tshuaj hauv qhov caws pliav ntawm cov tshuaj hormones steroid los txhawb caws pliav collagen degradation, silicone gel khoom thiab siv sab nraud ntawm cov tshuaj, thiab lwm yam. , Tab sis cov txiaj ntsig yog feem ntau poob siab.Kev nce qib ntawm ultra-pulse CO2 fractional laser thev naus laus zis ua ke nrog kev tshawb fawb tob txog cov kab mob ntawm cov caws pliav tau ua rau peb hloov cov txheej txheem kev kho mob caws pliav.Tam sim no, feem ntau cov kws tshawb fawb tawm tswv yim txog kev nce qib ntawm kev kho laser ntawm nti mus rau ib lub lis piam tom qab qhov txhab tshem tawm los yog ib qho tom qab phais.Lub qhov txhab tau zoo nyob rau lub sijhawm no, thiab caws pliav yog nyob rau theem pib ntawm hyperplasia.Lub exfoliative fractional laser yuav siv tau los qhia triamcinolone acetonide thiab lwm yam tshuaj.Cov kev kho mob muaj kev nyab xeeb dua thiab ua tau zoo dua, nrog cov txiaj ntsig zoo dua, uas txo qhov muaj peev xwm ntawm kev phais phais tom qab tshem tawm qhov caws pliav.
Vim li cas ablative CO2 fractional laser zoo dua li kev kho tsis yog-ablative fractional laser?
Lub fractional CO2 laser yog roj laser, thiab lub hauv paus ntsiab lus ntawm kev ua yog "focal photothermal action".Lub fractional laser generates arrays ntawm cov kab me me uas siv rau ntawm daim tawv nqaij los tsim ib qho chaw me me thermal puas nrog ntau yam peb-dimensional cylindrical lug.Muaj cov ntaub so ntswg tsis zoo nyob ib ncig ntawm txhua qhov chaw raug mob me me, thiab nws cov keratinocytes tuaj yeem nkag tau sai thiab ua kom nws zoo sai.Nws tuaj yeem ua rau collagen fibers thiab elastic fibers proliferate thiab rearrange, ua cov ntsiab lus ntawm hom I thiab hom III collagen fibers ze rau qhov qub piv, hloov cov qauv ntawm pathological caws pliav, maj mam soften thiab rov elasticity.Lub ntsiab haum ntawm cov fractional laser yog dej, thiab dej yog lub ntsiab ntawm daim tawv nqaij, uas yuav ua rau lub dermal collagen fibers yuav tsum rhuab mus shrink thiab denature, thiab induce lub qhov txhab kho cov tshuaj tiv thaiv nyob rau hauv lub dermis, lub collagen tsim nyob rau hauv. kom tso nyiaj, thiab txhawb kev loj hlob ntawm collagen, thiaj li txhim kho daim tawv nqaij elasticity thiab txo cov caws pliav, cov txheej txheem tseem ceeb suav nrog: ① kev puas tsuaj thiab cuam tshuam cov hlab ntsha ntawm cov hlab ntsha hauv cov caws pliav;② vaporize thiab tshem tawm cov caws pliav;③ inhibit fibrous cov ntaub so ntswg ntau lawm thiab ntau heev proliferation;④ induce fibroblast apoptosis.
Dab tsi yog qhov contraindications ntawm fractional laser?
Cov neeg uas muaj qhov caws pliav;cov neeg mob puas hlwb;active vitiligo thiab psoriasis, systemic lupus erythematosus;cev xeeb tub los yog lactation;cov neeg uas muaj photosensitivity;noj isotretinoin hauv 1 xyoo dhau los, tam sim no lossis ib zaug kis tus mob khaub thuas los yog kab mob Herpes yooj yim puas tau.Yog tias koj tau muaj lwm yam kev kho mob laser hauv 3 lub hlis, koj yuav tsum qhia qhov tseeb rau koj tus kws kho mob, leej twg yuav tshuaj xyuas seb koj puas tuaj yeem txais kev kho laser tshiab.
Cov ntaub ntawv saum toj no yog muab los ntawm laser diode tshuab tsum.
