Impedancemetry: ihe ọ bụ?

Impedance - bụ ihe instrumental usoro nke nchoputa, nke na-enyere chọpụta ebe na ọdịdị nke ndị ntị ọnwụ. Na ya, ị nwere ike nweta ihe ọmụma banyere ọnọdụ nke auditory tube, cochlea, n'etiti ntị, nakwa dị ka ha innervating irighiri akwara.

Nke a na usoro na-enye ohere ịchọpụta ọrịa ndị dị ka perforation nke eardrum, timpanoskleroz, mkpọchị patency nke auditory akpa, otitis media, otosclerosis na ndị ọzọ.

Na impedancemetry anọchi anya akpaka n'ihe shiee now conduction n'etiti ntị mgbe na-agbanwe agbanwe ikuku kọlụm nsogbu na mmetụta ụda. Nchịkọta nke agbanwe - na now nnabata, ma ọ bụ conductivity nke owuwu nke elu ma na etiti ntị na olu impedance.

Na impedancemetry gụnyere inwe ezi conductivity n'ihe mgbe ikuku mgbanwe. Nke a na-akpọ tympanometry. The ngwa na-achọpụta rụọ mgbanwe nnabata mgbe nsogbu enwekwu na abụọ na narị abụọ millimeters mmiri kọlụm na ẹsụhọde ya n'okpuru -400 millimeters.

Nchọpụta nke ventilashion ọrụ nke auditory tube

Impedance - ihe ọ bụ? Nke a ụzọ a nyochaa nke auditory ngwa maka ya Mbelata ma ọ bụ distortion. Otu ihe mere nwere ike Eustachian tube dysfunction.
