Uburyo bwo Guhindura Uburyo Bwiza: Uruhare rw'ikoranabuhanga rya laser mu buvuzi bw'indwara z'uruhu n'imitsi bigezweho

Imiti ya Lazeri yahinduye urwego rw’ubuvuzi bw’amaso—kubaga umutwe n’ijosi. Icyahoze gifatwa nk’inzozi za “star-trek” ubu ni ikintu cy’ingenzi mu byumba byo kubaga, gitanga urwego rw’ubuhanga budasanzwe. Dore isesengura ryimbitse ry’uburyo ikoranabuhanga rya lazeri ririmo guhindura imiterere y’ubuvuzi bw’indwara zo mu bwonko.

Ihame ry'Ubuvuzi

Imbaraga zo kuvura za imirasire ya laser muri ENTishingiye ku ihame rya selective photothermolysis na vaporisation.

Bitandukanye n'ibikoresho bisanzwe by'icyuma gikonjesha bishingiye ku gukata kwa mashini, imirasire ya laser itanga urumuri rwinshi ku rugero runaka rw'uburebure. Iyo uru rumuri ruhuye n'uturemangingo, rwinjizwa n'uturemangingo tw'amazi cyangwa hemoglobin. Uku gukurura bitanga ubushyuhe bwinshi, bigatuma uturemangingo twibandwaho duhinduka umwuka cyangwa tugahita twivanga.

CO₂ Laser: Ni urugero rwiza rwo kubaga mu mihogo. Inyurwa cyane n'amazi, bigatuma igabanya neza ubushyuhe buke.

Diode Lasers: Izi zikunze gukoreshwa hakoreshejwe imigozi yoroshye, bigatuma habaho uburyo bwo "gukora mu biro". Zibasira hemoglobine, bigatuma ziba nziza ku ndwara z'imitsi (nk'udukoko tw'ijwi cyangwa telangiectasasia).

Ibyiza byo Kuvura

Imiti ya laser itanga inyungu zitandukanye ugereranyije n'ubuvuzi gakondo:

Hemostasis (Umurima udafite amaraso): Laser ifunga imiyoboro y'amaraso na limfu iyo igabanyije. Ibi ni ingenzi cyane mu mutwe no mu ijosi, aho imiterere y'umubiri iba ikomeye kandi ubushobozi bwo kubona neza ari bwo buhambaye.

Uburyo bwo gukora neza:Bituma abaganga babaga bashobora gukuraho ibisebe neza, bikarindahafi y'ingingo nzima—ikintu cy'ingenzi mu kubungabunga ijwi no kumira.

Tekiniki idakoreshwa mu gukoraho:Mu bihe bimwe na bimwe (nk'isubiramo ry'ubuhumekero rya papillomatosis), laser ishobora gukoreshwa idakoze ku mubiri, bigagabanya imvune z'imikorere.

Uburyo bwo kuvura abarwayi bataha:Imirasire igezweho ikoresha fibre (KTP / Diode) yemerera abantu gukora ubuganga mu biro bakoresheje anesthesia yo mu gace runaka, birinda ingaruka n'ikiguzi cy'inzobere rusange.

Ibipimo by'ibanze (Ibibazo by'ingenzi byo kuvurwa)

Ikoranabuhanga rya laser rikoreshwa mu buvuzi bw’indwara zo mu mutwe n’iz’amaguru:

Indwara yo mu bwonko bw'umurabyo (Ijwi n'Inzira y'Indege):

Ibisebe byo mu majwi bitameze neza (polyps, nodules, Reinke's edema).

Kanseri yo mu mara (kanseri yo mu mara ya T1/T2 yo mu cyiciro cya mbere cy'indwara).

Papillomatosis isubira mu myanya y'ubuhumekero (RRP).

Gucika intege kw'ijwi ku maguru yombi (erytenoidectomy / cordotomy).

Ubumenyi bw'amaso (Ugutwi):

Gupima ibice by'umubiri (stapedotomy) ku bijyanye no gupima ibice by'umubiri (otosclerosis) (gukoresha laser ya CO₂ cyangwa Erbium kugira ngo hakorwe fenestra nyayo mu gice cy'ibirenge cya stapes nta gukomereka kwa tekiniki).

Gukuraho cholesteatoma n'ibibyimba by'imitsi yo mu gutwi ko hagati.

Ubumenyi bw'impuzankano (Izuru n'Imiyoboro y'amagufwa):

Kuvura telangiectasia yo kuva amaraso mu buryo bw'umwimerere (Osler-Weber-Rendu).

Kugabanya turbinate mu gihe cy'inzibacyuho idakira y'amazuru.

Umutwe n'Ijosi:

Leukoplakia yo mu kanwa na dysplasia.

Indwara yo kubura ibitotsi mu gihe cyo gusinzira (Laser-Assisted Uvulopalatoplasty – LAUP).

Umwanzuro

Ikoranabuhanga rya laser muri ENTsi igikoresho gusa, ahubwo ni uburyo bwo kongera amaboko y'umuganga ubaga. Dukoresheje uburyo bwo kureba mu buryo bwa mikorosikopi n'ubuhanga bw'urumuri, ubu dushobora kuvura indwara zitandukanye kuva kuri kanseri y'umwijima yo mu ntangiriro kugeza ku ndwara yo kubura umwuka mu gihe cyo gusinzira mu buryo bwihuse, bunoze, kandi bugakira vuba kurusha mbere hose.
