Umsebenzi we-Tube Eustachian

I-Tube Yokuhlola

I-tube eustachian, noma ithubhu yokuhlola, ixhuma indlebe ephakathi kuya nasopharynx engxenyeni engenhla yomphimbo ngemuva kwempumu. I tube itholakale nje ngenhla yezindlebe eziphakathi futhi inezinxantathu ekuvuleni okwenziwe oval kokubili. I-bone, i-cartilage, nama-fibrous tissue yenza i-eustachian tube. Ngaphakathi kwe-tube ngokwalo, kunezindawo ezihlukile, ingxenye engaphezulu ye-tube iyabushelela, kanti ingxenye engezansi ye-tube iqukethe i-cilia, noma izakhiwo ezinjengezinwele.

Ukwahlukana KweThubhu Eustachian ku-Children and Adult

Usayizi wesitembu ezinsaneni cishe u-17.5 mm, oqhubeka ukhula kuze kube ngu-37.5 mm ubude lapho ufika kubantu abadala.

I-Angle ye-tube emantwaneni nasezinganeni i-degrees ezingaba ngu-10 kuphela kusukela endlebeni ye-eye (Frankfort) indiza enezingqimba. Lokhu kuhluke kumuntu omdala, lapho i-angle ihamba khona cishe ema-45 degrees. Lo umehluko wama-degree angu-30 ubhekwa njengenye yezinto ezibangela ingozi yezingane ezithuthukisa indlebe.

Ukusebenza kahle kwemisipha nakho kuhluke ezinganeni nakubantu abadala. Kunemisipha emi-4 efaka isandla ekuvuleni nasekuvaleni ithubhu le-eustachian: i-veal palatine, i-levator veli palatine, i-salpingopharyngeus, ne-tensor tympani. Ngo-chidlren, lezi zinhlanzi zihamba phambili, kuyilapho zikhulile, zithinteka kakhulu. Lo mcabango ucatshangwa ukuthi ubangele ingozi eyandayo kubantwana abathuthukisa indlebe yokungasebenzi.

Umsebenzi we-Tube Eustachian

I-tube eustachian iyaziwa kakhulu ngeqhaza layo ekulinganiseni ukucindezela ngaphakathi kwendlebe ephakathi. Leli yiyona nendima ebalulekile, kodwa i-eustachian tube ithatha izindima ezintathu ezilandelayo:

• Ukucindezela ukulingana kwensimbi ephakathi
• Ukukhipha isikhala sensimbi ephakathi
• Ukuvikela indlebe ephakathi amabhaktheriya noma amagciwane

Ngokwesilinganiso ithubhu ye-eustachian ivule izikhathi ezingu-1 kuya kwezingu-2 ngehora. Uma ivuliwe, kuvame ukuhlala ivulekile cishe ngamasekhondi angu-0.3 kuya ku-0.5. I-tube ye-eustachian ivuleka kaningi futhi isikhathi eside uma ihlaselwa.

Ukucindezela ukulingana

Ukucindezela kwezulu kushintshe njengoba ushintsha ukuphakama futhi njengoba isimo sezulu sishintsha. Lapho ingcindezi yomkhathi iguquka, induku yendlebe ishintsha isimo ngenxa yokucindezela okungalingani phakathi kwendlebe ephakathi. Ngaphandle kokulinganisa ukucindezeleka, indlebe yezindlebe ayikwazi ukuphendula umsindo ngendlela efanayo futhi ukuzwa kwakho kuthintekile. Uma ingcindezi enendlebe ephakathi ingalingani futhi ingcindezi enkulu isetshenziswa, ungathola ubuhlungu futhi ezimweni ezimbi kakhulu indlebe ephukile ingaba khona. Uma indlebe yenza i-equalize ungase uhlangane nesimo "sokuphuma".

Ukususwa kweNtambo Ephakathi

Ukuze ugcine ukusebenza ngendlela efanele yezindlebe eziphakathi, isikhala sidinga ukuba sibe mahhala ketshezi nezinye izinhlanga. Izakhiwo ezincane ezinjengezinwele, ezibizwa ngokuthi i-cilia, zithuthukisa ngenkuthalo ukuvulwa kwethebhu ye-eustachian. Le nqubo ayikho incike emandleni futhi izokwenzeka ngokujwayelekile ngaphandle uma kunenkinga ngenqubo; njenge-primary ciliary dyskinesia.

Kanye phakathi kwezindlebe, phansi kwe-tube ine-mucus ne-cilia eshayayo (noma ehamba emuva nasemuva e-wave like motion motion); ukuhambisa izinto ngaphansi kwe-tube eustachian emuva komphimbo.

Izinto eziningana zingathinta umsebenzi ovamile wale nqubo ngokushintsha i-viscosity, noma ubukhulu be-mucus ku-tube eustachian. Izibonelo zezinkinga ezingashintsha ubukhulu be-mucus zihlanganisa: i-cystic fibrosis, i- otitis media , ne- sinusitis . Ukutheleleka kwama-bacterial kanye negciwane kungathinta umsebenzi ovamile wale nqubo futhi kungathatha inyanga eyodwa ngemuva kokuthola umsebenzi ovamile we-cilia ukuze ubuyele.

Ezinye izithiyo zingase zivimbele noma zivimbele kancane kancane ukuvulwa kwe-tube eustachian ngemuva komphimbo. I-adenoids ekhulisiwe ne-adenoids ezinganeni ezincane ingaba imbangela yalokhu kuvinjelwa.

Uma kudingekile i- adenoidectomy ingenziwa ukuze ikhulule isikhala esiseduze ne-eustachian tube.

Ukuvikelwa

Ngaphansi kwezimo ezivamile, ukuvulwa kwe-tube eustachian ngemuva komphimbo kuvaliwe. Lokhu kusebenza imisebenzi emithathu yokuvikela:

• Isivimbela amabhaktheriya namagciwane kusukela ekukhuphukeni kwe-tube eustachian
• Ivimbela umsindo kusuka ekuqaliseni ukuhamba ukuya endaweni ephakathi nendlebe
• Siza ukunciphisa ingcindezi yomsindo endlebeni ephakathi ngenxa yemisindo ezwakalayo

Lesi sivikelo siphazanyiswa yizifo ezibangelwa i-eustachian tube evulekile ngemuva komphimbo ukuze ihlale ivulekile. Isikhumba esikhulu se-eustachian yisibonelo salokhu futhi sibhekwa kabanzi yi-uphawu lokutshela ngokuzenzakalela, noma ukuzwa okungavamile kwezwi lakho siqu noma ukuphefumula.

Izindlela Zokuvula I-Tube Eustachian

Uma ushintsha ukuphakama, kuvamile ukuzwa izindlebe ezixhunyiwe . Ngenkathi ekuqaleni lo mzwelo uwukucasula nje, ngaphandle kokulingana okufanele, ubuhlungu bungase bukhule njengoba uqhubeka ukushintsha ukuphakama. Ukuze unciphise ukuzwa noma ubuhlungu, udinga ukudala ukuvulwa kwe-tube eustachian. Nazi ezinye zezindlela ozama ngazo:

• i-yawning
• sneezing
• ushingamu
• I-toynbee isebenza - ukugwinya ngenkathi ucindezela ikhala lakho
