Ingemuva:Nakuba ukukhishwa kwezinwele nge-laser kuye kwenziwa eminyakeni yamuva ukuze kukhishwe noma kuncishiswe izinwele ezimnyama ezingafunwa, ubuchwepheshe, kuhlanganise nezindlela ezifanele zezinhlobo ezahlukene zesikhumba nezindawo zomzimba, abukathuthukiswa.
Inhloso:Sibuyekeza izimiso zokukhishwa kwezinwele nge-laser futhi sibike ucwaningo olwenziwa kabusha lweziguli ezingama-322 ezikhishwe nge-laser ye-alexandrite yama-pulsed amade amade phakathi kuka-Januwari 2000 no-December 2002. ucwaningo lokubheka emuva.
Izindlela:Ngaphambi kokwelashwa, iziguli zahlolwa udokotela futhi zaziswa ngomshini, ukusebenza kahle kanye nemiphumela emibi engase ibe khona yokwelashwa.Ngokwesigaba se-Fitzpatrick, iziguli zihlukaniswa ngohlobo lwesikhumba.Labo abanesifo se-systemic, umlando wokuzwela ilanga, noma ukusetshenziswa kwezidakamizwa ezaziwa ukuthi zibangela i-photosensitivity abazange bafakwe ekwelashweni nge-laser.Konke ukwelapha kwenziwa kusetshenziswa i-alexandrite laser ye-long-pulse enosayizi wendawo ongashintshi (18 mm) kanye no-3 ms ububanzi be-pulse, esebenzise ama-nanometer angu-755 wamandla.Ukwelashwa kuphindaphindwa ngezikhathi ezahlukene kuye ngokuthi ingxenye yomzimba okufanele ilashwe.
IMIPHUMELA:Isamba sokulahlekelwa izinwele silinganiselwa ku-80.8% kuzo zonke iziguli kungakhathaliseki uhlobo lwesikhumba.Ngemuva kokwelashwa, kube namacala ama-2 we-hypopigmentation kanye namacala ayi-8 we-hyperpigmentation.Azikho ezinye izinkinga ezibikiwe.IZIPHETHO: Ukwelashwa nge-laser ye-alexandrite ye-long-pulse kungahlangabezana nokulindelwe yiziguli ezifisa ukususwa izinwele unomphela.Ukuhlolwa kwesiguli ngokucophelela kanye nemfundo ephelele yesiguli ngaphambi kokwelashwa kubalulekile ekuthotshelweni kwesiguli kanye nempumelelo yale nqubo.
Njengamanje, ama-laser amaza ahlukahlukene asetshenziselwa ukususwa kwezinwele, kusukela ku-695 nm ruby laser ekugcineni okufushane kuya ku-1064 nm Nd: YAG laser ekugcineni.10 Nakuba ubude begagasi obufushane bungakufinyeleli ukususwa kwezinwele okufiswayo kwesikhathi eside, amaza amade amade asondelene kakhulu namazinga okumunca ukukhanya e-hemoglobin ene-oksijini ne-melanin ukuze asebenze ngokugcwele.I-alexandrite laser, etholakala cishe phakathi nendawo, iyisinqumo esihle esinobude obungamaza angama-755 nm.
Amandla e-laser achazwa ngenani lama-photon alethwe kokuhlosiwe, ngama-joules (J).Amandla edivayisi ye-laser achazwa inani lamandla alethwa ngokuhamba kwesikhathi, ngama-watts.I-Flux inani lamandla (J/cm 2) elisetshenziswa endaweni yeyunithi ngayinye.Ubukhulu bendawo buchazwa ububanzi be-laser beam;Ubukhulu obukhulu buvumela ukudluliswa kwamandla ngokuphumelelayo ngedermis.
Ukuze ukwelashwa nge-laser kuphephe, amandla e-laser kufanele abhubhise i-follicle yezinwele ngenkathi egcina izicubu ezizungezile.Lokhu kufezwa ngokusebenzisa isimiso sesikhathi sokuphumula esishisayo (TRT).Igama libhekisela esikhathini sokupholisa sethagethi;Ukulimala okushisayo okukhethiwe kufezwa lapho amandla alethwayo ede kune-TRT yesakhiwo esiseduze kodwa emfushane kune-TRT ye-follicle yezinwele, ngaleyo ndlela ingavumeli okuhlosiwe ukuba kuphole futhi ngaleyo ndlela kulimaze i-follicle yezinwele.11, 12 Nakuba i-TRT ye-epidermis ikalwa ku-3 ms, kuthatha cishe u-40 kuya ku-100 ms ukuze i-follicle yezinwele iphole.Ngaphezu kwalesi simiso, ungasebenzisa futhi idivayisi yokupholisa esikhumbeni.Umshini womabili uvikela isikhumba emonakalweni oshisayo futhi unciphisa ubuhlungu esigulini, okuvumela opharetha ukuthi alethe ngokuphepha amandla engeziwe.
