Acoustic neuroma

Acoustic neuroma - a benign bundu, iyo yakaumbwa kubva masero enzvimbo rechinomwe cranial etsinga. Inoitwa anoverengeka zvikamu, izvo basa kunzwa uye vestibular nerevane kuongorora uye kuzvidzora. zvokurwara ichi ndizvo varwere vakwegura makore 50-60. Nokuti bundu ichi kunoratidzwa kunonoka kukura.

etiology

The zvinokonzera namamota kwakadaro haangasimbiswi, zvinokonzera njodzi uyewo asingazivikanwi. Mune zvisingawanzoitiki kacho acoustic neuroma chiratidzo neurofibromatosis, inova majini chirwere. With ichi kunotoda mufananidzo bundu kazhinji bilateral.

zviratidzo

Kunzwa kurasikirwa, dzungu - zviratidzo izvo zvaizobatsira acoustic neuroma. Zviratidzo kuoneka pashure pfupi pashure panowanikwa namamota uye tsika kuti zvemo zviitiko. Kunzwa vanotaura ndiye wokutanga kunotoda kuratidzwa neuromas. It ari hunhu nokushatiriswa iyo hworatidza pachayo kudivi bundu. Varwere vanonzwa ruzha siyana uye ruzha. Vamwe havana hanya zvinokosha kutyorwa auditory ushande.

The zvishoma nezvishoma imwe nebundu chinokurwadzai vertigo, izvo dzimwe nguva tora pamusoro hunhu vestibular nematambudziko. Muchiitiko chino, zviri pamwe svoto uye kurutsa. An Chinangwa kudzidza padzakacherechedza chinjikira maonero nystagmus, iyo yava kutaurwa zvakananga maonero kurutivi bundu vakawanda. Cochlear, vestibular chikamu etsinga vari sei panguva imwe chete.

Zvinotevera zviratidzo kuonekwa kana chirwere vari paresthesias uye kurwadziwa, izvo vemunyika parutivi bundu lesion. Ivo yakasindimara, dzava zvakasikwa. In yokutanga nguva chirwere wehurumende, vanogona nomuzvarirwo kuserera. marwadzo aya anokonzerwa kumanikidzwa, iyo inoshandura bundu iri riri trigeminal etsinga, pakukoka pedyo vestibular-cochlear. Mune zvimwe zviitiko, marwadzo kutora paroxysmal. Naizvozvo, vakarasika kuti trigeminal neuralgia, uye mazino chirwere. Sezvo bundu kunowedzera kumanikidza uye Nokurwadziwa narini.

Uyezve zvekuchipatara kuratidzwa kuvimba kukura anomera. With kukura uye shure azviratidze zviratidzo cerebellar tishu. With pave shure uye pasi inobata vagus uye glossopharyngeal tsinga, umo nyonganyonga yacho kumedza basa, nehanya, kuora mwoyo, phonation, ungaderedza gag dzepanguva.

Acoustic neuroma inenge hakupesani muitisi kutsinga dzinouya uye motokari chaitika. Pyramidal hurongwa zvinovhiringidzika zvishoma, pamwe zvakawedzera hunenge.

Gare gare zviratidzo chepfungwa kumanikidzwa kuri kuwedzera. In ichi nepaburi munda maonero.

Diagnostics

Zvinoda kushandiswa zvinotevera nzira:

- chinhu audiogram, iyo inobatsira kuyera kunzwa neimwe nzeve;

- electronystagmography iyo anobvumira kuti chamber nokukurumidza ziso kufamba kana dzungu apo achizadza nzeve Canal mhepo kana mvura inopisa;

- kwokunzwa kuongororwa kuti zvinobatsira kuongorora kwaiita pfungwa hunde;

- rinobva resonance kuri;

- computed tomography.

Nzira dzose idzi kubvumira kusiyanisa zvokurwara ichi nezvimwe mapundu uropi akadai neuroma uropi.

mabatiro

Kune akawanda marapirwo kuti bundu iri: Rinda nokumirira, radiosurgery, kuvhiya. Pana hukuru duku, unexpressed kurapwa anokuzviratidza uye varwere vakwegura vakashandisa nzira yokutanga. Mune mamwe mamiriro ezvinhu zvose, acoustic neuroma kunoda kuvhiyiwa.
