Uthola yini lokho okuhlanganisa ukukhuliswa komsindo ophansi we-acoustic we-hearing hearing ne-high-frequency sound access of a implant cochlear? Uthola okuthiwa i-hybrid cochlear implant. Ukufakelwa kwe-hybrid cochlear kuyinkimbinkimbi eyenziwe ngokuhlinzwa ephethe iprosesa yomsindo wangaphandle esebenza nengxenye ye-cochlear implant of the device futhi isebenza njengesizwa sokuzwa ukulahlekelwa kwezwi eliphansi.
Isebenza kanjani?
Amakhomphyutha enkampanini yomsindo wangaphandle athatha imisindo, futhi leyo imisindo iguqulwa kolwazi lwedijithali. Lezi zomsindo zithunyelwa ngokuqondile kwi-electrode array ku- cochlea .
Ngesikhathi esifanayo, i-acoustic / hearing aid ingxenye iqoqa imisindo ephansi-imvamisa, ikhulise, futhi lezo zomsindo zidluliselwa emgodini wezindlebe emgqonyeni wezindlebe nasezindlebeni zangaphakathi.
I-cochlea iqoqa ulwazi oluzwakalayo oluvela emithonjeni yombili futhi ithumela ebuchosheni obunengqondo ngalokho okuzwakalayo.
Ubani Okhethiwe?
Ukufakelwa kwe-hybrid cochlear kuvunyelwe ukusetshenziswa kwe-unilateral (eyodwa indlebe) kubantu abaneminyaka engu-18 ubudala nangaphezulu aba:
- sishintsha ukuzwa kwe-frequency hearing futhi
- okujulile kuya ekujuleni kwenhlanhla yokuzwa ukuzwa kwenzwa nge
- ukuhlomula okulinganiselwe ngokufanelekayo ukuzwa izinsiza zokuzwa.Kodwa ukuzwa okuphansi kwamagundane kufanele kube emkhawulweni ovamile ukuze ulinganise ukulahlekelwa kokuzwa (okungcono kunama-60dBHL) .Ukuzwa ukuzwa okuvame ukuphakama ezindlebeni zokufakelwa kumele kube nokuphakama okukhulu noma okulingana no-75dBHL ngo-2000, 3000, no-4000Hz. Ngendlebe ehlukile, leso silinganiso kumele sibe sikhulu kunaleyo noma silingane no-60dBHL.
Okunye ukungafani
Ngokwezinkombandlela ze-Nucleus Hybrid, awuyena ozokhethwa kulokhu okufakelwayo uma ukuzwa kwakho kungabangelwa izilonda ze-acoustic nerving or central pathway auditway, isifo sesisindo esiphakathi (noma ngaphandle kwembobo eardard), awunayo i-cochlea (indlebe yangaphakathi), noma ube nesifo esinzima sokuzwa ukulahlekelwa kweminyaka engu-30 noma ngaphezulu.
Umsindo we-Frequency Frequency
Kulokhu, ama-frequencies aphansi abhekwa njengomsindo olinganiselwe kuhlanganise no-500Hz. Amazinga aphansi ahlanganisa imisindo yevolumu, njenge "ah" ne "oo". Banikeza isigqi nomculo wokukhuluma futhi badlulisele ulwazi lwevolumu. Izibonelo zemisindo ephansi-imvamisa ukuduma, i-drums bass, noma izwi elijulile lomuntu.
Imisindo Ephezulu-Frequency
Amazinga aphezulu afaka ukucaca nokucabangela izinga elizwakalayo. Imisindo ehambisanayo, njenge "s" ne "f" ifaka isandla ekuqondeni inkulumo. Izibonelo zemisindo ephezulu kakhulu zihlanganisa amabellane, izinyoni ezigubhayo, namacilongo.
Izinzuzo ze-Implantation Hybrid Cochlear
I-implantation ye-hybrid cochlear ivumela labo ababengekho ngaphambili ukuthi bazuze ekuboneni okuphezulu kwemvamisa kwemisindo engenakwenzeka nge-hearing aid ngenkathi benganikeli imizila ephansi ehlala phansi ku-cochlea ngenxa ye-short electrode array. Abasebenzisi futhi babika ukwaneliseka okwengeziwe ngenkulumo emculweni nomculo wekhwalithi ezwakalayo ne-hybrid implant versus aid aid kuphela.
Izimo ze-Implantation ye-Hybrid Cochlear
Inqubo yokuhlinza iyadingeka ukuze kubekwe ukufakelwa kwe-cochlear, futhi lokho kubeka izingozi ezihambisana nokutheleleka kanye ne-anesthesia. Lapho sekufakwe ukufaka, ezinye izindlela zokwelapha ezifana ne- MRI kanye ne-electroconvulsive therapy azikwazi ukwenziwa.
Ukuhlukunyezwa kwekhanda kungalimaza ukufakwa. Ikhwalithi yomsindo ingahle ihlanekezwe ngokuzungezile uma imayelana nemithombo ethile yokuphazanyiswa, njengezinhlelo zokuphepha, imishini yokuxhumana yeselula, kanye nama-radios amabili. Kufanele kuphawulwe ukuthi lokhu kubuchwepheshe obusha, futhi kunomkhawulo wesikhathi eside otholakala kubasebenzisi.
Ukuze uthole olunye ulwazi, noma ukuthola ukuthi ungumuntu ozobhapathizwa, thintana no-audiologist wakho.
