Lafta kaliga: anatomy iyo cudurada

lafta kaliga foomamka calvarium ah. Waxaa la xidhiidha dareenka (aragga iyo urta), fulinta shaqo ah dual, wuxuuna ka kooban yahay laba qaybood: siman oo toosan. waaxda siman u qaybsan yahay sanka unpaired iyo qaybo ka mid ah orbital uumi.

lafta kaliga ka kooban yahay afar qaybood: laba qolfo orbital, sanka iyo aad kaliga. dusha kaliga ayaa Iskeelada soo socda: kaliga (Iska Fududeeyaan), maskaxda (colnimada Nabiga) iyo laba temporal (dhinaca). lafta kaliga ee geedi socodka of isbedel horumar, horumarisa tuulmo la kaliga, taasoo keentay in foodda qabow beddelay: ka mid marwalba uu noqday convex. Oogada kaliga waa convex horteeda, midline siman waxaa jira in yar oo quruxsan dareemi. The qaybo xukuntaa oogada sare ee dulmiga galo dusha orbital. lafta kaliga (qolfo dusha) laga soocay dusha sare ee line temporal temporal ku arcuate.

cudurka

Hyperostosis lafta syndrome kaliga ama Morgagni-Stewart-Morel la og yahay in sayniska muddo ka badan 250 sano, laakiin xataa maanta danta saynisyahano cudurka tani sii socoto, waxna lagama. Sida natiijo ah oo cudurkan waxaa jira maskaxda, daaqsinka-vascular iyo dheefshiidka iyo cudura hormoon. qorayaasha Qaar ka mid ah calaamadaha ugu weyn waxaa ka mid ah hyperostosis cayilka, hypertension, madax xanuun joogto ah. Inta badan cudurkan waxa la xidhiidha xanuunada dhimirka (myotonia Atrophic, xanuunada maskaxda, cudurka cerebrovascular, cudurka rheumatoid). Si kastaba ha ahaatee, ilaa iyo haatan ma aasaasay qodob oo kala duwan etiological.

Osteoma lafta kaliga - cudur dhif ah lagu gartaa formation of burooyin aan halis ahayn. Waxaa la rumeysan yahay in etiology ee osteoma la xiriira arrin la iska dhaxlo (itimaalka gudbinta cudurada farcamay of 50 boqolkiiba), sida ku cad exostosis lagu dhasho.

pathogenesis cudurka

Osteomas yaqaan saddex nooc: adag, oo geed isbonji la medullary. osteoma adag ka kooban yahay wax cufan (taarikada), kaas oo loo qoondeeyey waxa barbar socda dusha sare ee neoplasm ah. osteoma nooca Medullary ku jira godadka ballaaran oo waxaa ka buuxa dhuuxa lafaha.

Sida laga soo xigtay Virchow kala saaro laba nooc oo burooyinka: geteroplasticheskie (soo sameeyey unugyo), hyperplastic (soo sameeyey lafta). Kooxdu waxay ugu horeysay ka mid ah osteophytes - layers yar ee lafta. Haddii ay mashquulin goobada oo dhan lafta, waxaa loo yaqaannaa hyperostosis. Haddii mass lafta waxaa loo soo saaray qaab burooyinka bannaan ee xaddidan, waxaa exostosis, haddii la jira gudahood lafta - enostosis.

calaamadaha Clinical osteoma

Osteomas, baxaya on dusha hoose oo lafta kaliga, oo ay la socdaan madax xanuun joogta ah, suuxdin, xanuunada xasuusta, calaamadaha cadaadiska intracranial kordhay. Haddii buro waa kooban ee "Sella" muujin kartaa dheelitir la'aanta hormoon. Marka kooban ee degaanka JQSHM horumarsan diplopia, exophthalmos, ptosis, anisocoria, aragga hoos u, iwm

Inta badan osteoma kooban ee (lateral) oogada sare ee lafta. Osteomas, kooban dibaddeeda oo saxan lafaha qalfoofka, muujiyey qaab waxbarasho cufan, aan xanuun lahayn oo dhab ah. Cilad ku salaysan tahay natiijada bukaan eegida iyo shucaaca. Marka koritaanka buro extracranial loo jeediyo neefsashada, urta, mararka qaarkood doorinaynaa lafaha wajiga.

Oo weliba inta badan faafin osteoma intracranial. burooyinka noocan oo kale ah waxaa ku baabbi'iyo derbigii gadaal ka mid ah JQSHM kaliga, keenaya riixo walax maskaxda. Haddii in this habka cudurka bahal la xidhiidha horumarinta arachnoiditis, malax maskaxda, meningitis. Kala cudurka ka osteosarcoma iyo osteomyelitis. Neoplasms la saaraa qaliin.
