Bone Frontal: nokwakheka kwegazi

Ithambo ngokungqalileyo yakha calvarium. Inxulunyaniswa izivamvo (emehlweni kunye nevumba), enza umsebenzi ezimbini, kwaye iqulathe amacandelo amabini: abathe nkqo nabathe tye. isebe oxwesileyo yohlulwe ngeempumlo unpaired kunye nezahlulo Orbital zomphunga.

Ithambo ngokungqalileyo iqulathe izahlulo ezine: isikali ezimbini Orbital, ngeempumlo kunye ngokungqalileyo. umphezulu Frontal unawo isikali zilandelayo: ngokungqalileyo (elingaphandle), ingqondo (ngaphakathi) kunye ezimbini temporal (icala). Ithambo ngokungqalileyo kwinkqubo utshintsho zazivelela, iphuhlisa iindonga ngokungqalileyo, nto leyo ebunzi epholileyo lilimbi ukusuka longele waba khaxa. Umphezulu ngokungqalileyo yi khaxa ngaphambili, umgca agudileyo kukho ukuphakama encinane buqapheleke. Imimandla Icipande kumphezulu engaphandle lwezi zinto scales engena kumphezulu Orbital. Ithambo ngokungqalileyo (isikali kumphezulu) siyahlukana phezu komgca arcuate temporal temporal.

isifo

Hyperostosis of the ngokungqalileyo ithambo syndrome okanye Morgagni-Stewart-Morel yaziwa kwinzululwazi iminyaka engaphezu 250, kodwa namhlanje nomdla izazinzulu kwesi sifo kuyaqhubeka. Ngenxa yale sifo kukho yengqondo, kwezityalo nemithambo kunye pathways nokuphazamiseka hormone. Abanye ababhali ukuba iimpawu hyperostosis eziphambili ziquka ukutyeba, lwegazi, intloko ebuhlungu sizingise. Amaxesha amaninzi le sifo kudityaniswe abagula ngengqondo (myotonia atrophic, ukuphazamiseka ebuchotsheni, isifo cerebrovascular, usuleleko samathambo). Noko ke, ukuza kuthi ga ngoku akukho kusekwa into ecacileyo etiological.

Osteoma wethambo ngokungqalileyo - isifo enqabileyo luphawulwa ukuyilwa yamathumba ebubonisayo. Ekukholelwa ukuba umyalezo we osteoma ezinxulumene factor ilifa (amathuba yokudlulisela ngezifo lenzala-50 epesenti), njengoko kuchaziwe exostosis naso.

Le Pathogenesis kwesifo

Osteomas eyaziwa iindidi ezintathu: eziqinileyo, kunye imfunxa medullary. osteoma Solid ibandakanya izinto ashinyeneyo (amacwecwe), apho zicwangciswe ngaxeshanye phezu a neoplasm. Medullary uhlobo osteoma iqulethe nemingxuma kabanzi eye zizaliswe umongo wethambo.

Ngokutsho Virchow ukwahlula iintlobo ezimbini yamathumba: geteroplasticheskie (wabumba ukusuka kwizicwili), hyperplastic (wabumba amathambo). Iqela lokuqala luquka osteophytes - maleko ezincinane kule ithambo. Ukuba asezikhundleni yonke achazwe apha wethambo, zibizwa hyperostosis. Ukuba eqina ikhutshwa ngohlobo yamathumba kwisithuba elinganiselweyo, nto exostosis, ukuba ikhoyo nokubakho ngaphakathi ithambo - enostosis.

Iimpawu Clinical osteoma

Osteomas, asakhulayo phezu engaphakathi ithambo ngokungqalileyo, ephelekwa yintloko ebuhlungu rhoqo, ukuxhuzula, memory ukuphazamiseka, iimpawu eyandileyo uxinzelelo intracranial. Ukuba Ithumba yenzelwe ukuba i "sella" ngazo kungalingani hormone. Xa yenzelwe kwindawo sinuses ephuhliswa diplopia, exophthalmos, ptosis, anisocoria, sinciphise umbono, njl

Kaninzi osteoma eyendayo olungaphandle (sclerosis) kobuso ithambo. Osteomas, yenzelwe ngaphandle kwipleyiti ithambo ukakayi, wabonakaliswa ngohlobo imfundo ashinyeneyo, elingenabuhlungu kwaye ibe yinyani. Uxilongo isekelwe kwiziphumo zeklinikhi radiology. Xa ukukhula ithumba extracranial aphazanyiswa ukuphefumla, ivumba, maxa wambi zikhubazekile amathambo ebusweni.

Kodwa amaninzi ukusasaza osteoma intracranial. yamathumba ezinjalo abatshabalalisa udonga elingasemva sinuses ngokungqalileyo, ibangela ucinezelo ukwimo ebuchotsheni. Ukuba kule usulelo nkqubo yezifo ezinxulumene ukuphuhlisa arachnoiditis, ithumba ebuchotsheni, meningitis. Ezohlula sifo ukusuka osteosarcoma kunye osteomyelitis. Neoplasms zisuswa intsumpa.
