Imvelaphi:Nangona ukususwa kweenwele ze-laser kuye kwenziwa kwiminyaka yakutshanje ukususa okanye ukunciphisa iinwele ezimnyama ezingafunekiyo, iteknoloji, kubandakanywa neendlela ezifanelekileyo zeentlobo ezahlukeneyo zesikhumba kunye neendawo zomzimba, ayikalungiswa.
Injongo:Siphonononga imigaqo yokususwa kweenwele ze-laser kwaye sichaze uphando olwenziwayo lwezigulane ze-322 eziye zathatha i-3 okanye ngaphezulu kwe-alexandrite laser hair ukususwa kweenwele phakathi kukaJanuwari 2000 kunye noDisemba 2002. isifundo se-retrospective.
Iindlela:Ngaphambi kokuba unyango, izigulane zavandlakanywa ngugqirha kwaye zaziswe ngendlela, ukusebenza kakuhle kunye nemiphumo enokubakho yonyango.Ngokohlelo lweFitzpatrick, izigulane zihlelwa ngokohlobo lwesikhumba.Abo banesifo se-systemic, imbali yokuvalelwa kwelanga, okanye ukusetyenziswa kweziyobisi ezaziwa ngokubangela i-photosensitivity kwakungabandakanywanga unyango lwe-laser.Zonke unyango lwenziwa kusetyenziswa i-alexandrite laser ye-long-pulse kunye nobukhulu bendawo engaguqukiyo (18 mm) kunye ne-3 ms ububanzi be-pulse, eyayisebenzisa i-nanometers ye-755 yamandla.Unyango luphinda luphindwe ngamaxesha ahlukeneyo ngokuxhomekeke kwinxalenye yomzimba ekufuneka iphathwe.
IZIPHUMO:Ireyithi yokulahleka kweenwele iyonke iqikelelwa ukuba yi-80.8% kuzo zonke izigulane kungakhathaliseki ukuba luhlobo luni lwesikhumba.Emva kokonyango, kwakukho iimeko ze-2 ze-hypopigmentation kunye neemeko ze-8 ze-hyperpigmentation.Azikho ezinye iingxaki ezichaziweyo.IZIGQIBO: Unyango lwe-laser ye-alexandrite ye-long-pulse inokuhlangabezana nokulindela izigulane ezinqwenela ukususwa kweenwele ngokusisigxina.Uvavanyo olunyamekileyo lwesigulane kunye nemfundo ecokisekileyo yesigulane ngaphambi kokuba unyango lubaluleke kakhulu ekuthotyelweni kwesigulane kunye nempumelelo yolu buchule.
Okwangoku, i-laser ye-wavelengths eyahlukeneyo isetyenziselwa ukususwa kweenwele, ukusuka kwi-695 nm ruby laser ekupheleni okufutshane ukuya kwi-1064 nm Nd: YAG laser ekupheleni kwexesha elide.10 Nangona amaza amaza amafutshane engakufezekisi ukususwa kweenwele okunqwenelekayo kwexesha elide, amaza amaza amade asondele kakhulu kumazinga okufunxa ukukhanya kwehemoglobin eneoksijini kunye nemelanin ukuze isebenze ngokupheleleyo.I-alexandrite laser, ebekwe phantse embindini we-spectrum, lolona khetho lufanelekileyo kunye nobude be-755 nm.
Amandla e-laser achazwa ngenani leefotoni ezinikezelwa kwithagethi, kwiijoules (J).Amandla esixhobo se-laser achazwa ngumthamo wamandla ahanjiswa ngexesha, kwiiwatts.I-Flux yinani lamandla (J / cm 2) elisetyenzisiweyo kwindawo yeyunithi.Ubungakanani bendawo buchazwa ngobubanzi be-laser beam;Ubungakanani obukhulu buvumela ukuhanjiswa kwamandla ngokufanelekileyo ngedermis.
Ukuze unyango lwe-laser lukhuseleke, amandla e-laser kufuneka atshabalalise i-follicle yeenwele ngelixa egcina izicubu ezijikelezileyo.Oku kuphunyezwa ngokusebenzisa umgaqo wexesha lokuphumla kwe-thermal (TRT).Eli gama libhekisa kwixesha lokupholisa koko kujoliswe kuko;Umonakalo okhethiweyo we-thermal ufezekiswa xa amandla ahanjiswayo ede kune-TRT yesakhiwo esikufutshane kodwa mfutshane kune-TRT ye-follicle yeenwele, ngaloo ndlela ingavumeli ukujoliswe kuyo kuphole kwaye ngaloo ndlela yonakalise i-follicle yeenwele.11, 12 Nangona i-TRT ye-epidermis ilinganiswa kwi-3 ms, ithatha phantse i-40 ukuya kwi-100 ms ukuba i-follicle yeenwele ipholile.Ukongeza kulo mgaqo, ungasebenzisa kwakhona isixhobo sokupholisa esikhumbeni.Isixhobo zombini sikhusela ulusu kumonakalo onokwenzeka we-thermal kunye nokunciphisa intlungu kwisigulane, ukuvumela umqhubi ukuba anikeze ngokukhuselekileyo amandla amaninzi.
