I hriatna hloh vek mah la, aw khawvelah i kir leh thei ang em? - Auditory Brainstem Implant (ABI) chungchang hi i zir chiang ang u.

I hnaih bertu, i fa ngei pawh ni thei, bengngawnga piang emaw, natna emaw, accident emaw eng emaw avanga hriatna hloh vek a nih chuan i lungngaihna leh tanpui theih lohna i neih chu thumal hmanga sawi a harsa hle. "I dam chhung zawng hetiang hian a awm dawn em?" Mahse, technology hmasawnna avang hian tûn laiah hian hriatna hloh nasa ber berte tân pawh êng thlen thei tûr hmanrua a awm a ni. Chu chu tunlaia kan sawi mek hmanraw bik pakhat a ni.

A awlsam zawngin ABI chu eng nge ni?

ABI hi `Auditory Brainstem Implant` tih tawifelna a ni. Sinhala tawng chuan `Auditory Brainstem Implant` tihna a ni. Hei hi hriatna hloh thuk ber, chu chu beng chhungril lama ri mantu (`cochlea` emaw beng hnah) emaw, chu aw signal te thluaka phurtu nerve (the auditory nerve) emaw chuan sound , emaw, pian tirh atanga awm lo emaw, hriat theihna atana hmanraw bik a ni.

I beng atanga i thluak thlenga aw phurtu nerve chu kawngpui angin ngaihtuah rawh. He bridge hi a chhiat chuan sound hian a cross thei lo va, thluak a thleng thei lo. Chutah chuan ABI device chu a rawn lut a, a bridge (nerve) chhe tawh chu a bypass a, thluak chhunga hriatna control tu (brainstem) lamah signal a thawn nghal a ni. Hei hi hriatna pangngai angin a ri lo a, mahse aw khawvel nena inzawmna siam leh theihna hun tha tak a pe che a ni.

He device hi eng ang nge a nih? Pang hnih a nei em?

Ni e, he device hian part lian pahnih a nei a. Pakhat chu taksa pawnah bun a ni a, pakhat zawk chu surgery hmanga taksa chhungah dah a ni.

1. Processor: Hei hi beng chungah emaw, lu sir lamah emaw, hriatna hmanrua ang maia bun thin a ni. I chhehvela aw awmte chu microphone hmangin a pickup a ni. Chumi hnuah chuan chu aw chu electrical signal-ah a chantir a, taksa chhunga processor-ah a thawn ta a ni. Zana i mut hunah he pawn lam hi paih chhuah tur a ni.

2. Internal Implant: Hei hi vun hnuaia surgery hmanga dahna hmun a ni. Part dang pahnih a nei bawk.

• Receiver-stimulator: He part hi lu sir lama vun hnuaia inzawm hian pawn lam atanga signal a dawng thin.
• Electrode paddle: He receiver tawp lama paddle te tak te hi uluk takin thluaka cochlear nucleus complex chungah dah a ni. Hei hian thluak chu direct-in a tichak a, aw hriatna a siam bawk.

He enkawlna hi tute tan nge a inhmeh ber?

ABI hi hriatna lama harsatna nei zawng zawng tan a tha lo. Hearing aid dang emaw cochlear implant emaw hmanga hlawkna hmu thei lo, hriatna lama harsatna thuk ber nei tan bik a siam a ni.

He technology hi Neurofibromatosis 2 (NF2) tih hming pu, genetic condition hmuh tur awm lo tak tak nei tan siam a ni. He natnaah hian auditory nerve-ah hian tumor (acoustic neuromas) a lo awm thin. Heng tumor te hi surgery hmanga lakchhuah a nih pawhin auditory nerve chu a tichhe vek thei a ni. Hei hian beng pahnihah hriatna a hloh vek thei a ni.

Chu bâkah, ABI hi a hnuaia natna nei puitling, naupang leh naute tân a hlawkpui thei bawk:

• Hriatna lama harsatna nei (aplasia) neia piangte tan.
• Auditory nerve a lo thang tha lo (`hypoplasia`) tan.
• Beng chhung lam, cochlea-a ruhro (cochlear ossification) engemaw zat avanga hriatna hloh tawhte tan chuan.
• Luruh hliam na tak (temporal bone fracture) avanga auditory nerve tihchhiat tawhte tan.
• Enkawlna dang hmanga tihdam theih loh hriatna hloh thuk tak nei tan.

ABI leh Cochlear Implant hi eng nge an danglamna?

An pahnih hian hriatna hmanrua ni mah se, an hnathawh dan leh an hman dan chu a danglam vek a ni. He table hi i en chuan awlsam takin i hrethiam ang.

Operation hma leh operation hnuah eng nge thleng?

Surgery neih hmain

Hei hi thutlukna lian tak a nih avangin operation hmain nang leh i dinhmun uluk takin enfiah hmasa phawt ang che. Hei hian test engemawzat a huam ang:

• Hearing tests: I hriatna level hi hearing aid hmanga teh a ni a, hearing aid hmang lo pawhin a teh thin.
• Communication assessment: Speech therapist chuan i tawng hmasawnna leh inbiakpawhna style a enfiah ang.
• Electrophysiological test: Hriatna hloh chu khawiah nge a awm tih leh eng chen nge a awm tih chiang taka hriat theih nan special test an nei thin.
• Scans: I beng chhung lam, auditory nerve leh i thluak hmun kaihhnawih te en turin CT scan leh MRI scan nei turin an ti thei che a ni.
• Medical history: I doctor chuan i medical history kimchang leh i hriatna hloh chungchang chipchiar takin a zawt ang.

Operation hnuah

Operation hnuah ni hnih atanga ni li chhung damdawi inah i awm a ngai dawn a ni. Hei hi `NF2` tumor lakchhuah ruala tih a nih chuan damdawi ina awm rei pawh a rei thei.

Mahse, hre reng ang che, operation hnuah pawh device hian hna a thawk nghal lo. Medical team hian operation an neih atanga kar 4 atanga kar 6 vel hnuah he device hi an activate ang a, chutih hunah chuan hliam te chu a dam tha tawh ang. Chumi hnuah chuan kum khatna atan thla tin i luh a ngai ang a, i device settings (programming) chu i duh angin i siamrem ang.

Engtin nge a rah chhuah? Risk a awm em?

Results leh hlawkna te

Sawi hmasak tur chu ABI hian hriatna pangngai a siam leh ngai lovang tih hi a ni. Mahse, a hlawknate chu a langsar hle a ni:

• Aw hriatna: I chhehvela thawm (ui ri, phone ri, car rawn hnaih ang chi) i hmu tan thin.
• Aw hrang hrang: 1.1.Naupang aw leh puitling aw ang chi hi i thliar hrang thei a, i hre thei bawk.
• Lip-reading a awlsam ta: Mi pakhatin a thusawi laia a ri ruala a hmui i en hian a thusawi hriatthiam theihna chu nasa takin a tipung a ni.

Mi tinah result a inang lo hle. Naupang kum naupang tak atanga (an hriatna hloh rei tak a nih hma) ABI dawng thinte chuan puitling aiin thumal hriatthiamna an nei tha zawk tih hmuhchhuah a ni.

Risk leh complication awm thei te

Hei hi thluak surgery buaithlak tak a nih avangin thluak surgery eng pawha hlauhawm awm fo pawh a awm bawk. Medical team tawnhriat ngah takin an tih chuan harsatna awm theihna a tlem hle. Harsatna awm thei thenkhat chu:

• Thluak vel tui (`Cerebrospinal fluid`) a leak chhuak thin.
• Device a thawk tha lo emaw, implanted electrode a kal emaw.
• Hliam natna.
• Hri kai, meningitis ang chi te.
• Hmai nerve (`Facial nerve palsy`) tihchhiat.
• Hriatna nena inzawm lo hmun dang stimulation avanga lungawi lohna.

I medical team chuan operation hmain heng zawng zawng hi chipchiar takin an sawiho ang che.
