Frontal iwi:'anatomia a me ka pathology

Ke frontal iwi 'ano apau loa i ka calvarium. Ua Ua pili me ka makaukau no (maka a me ka honi), hoʻokō i kekahi kuleana pili i pālua, a he mau pauku: papamoe, a me ka vertical. Papamoe Oihana Ua maheleia i unpaired nasal a me orbital māhele o ka mahu.

Ke frontal iwi ninoieo o ka eha māhele: elua orbital, nasal a me ka frontal unahi. Frontal ili i ka kēia mau unahi: frontal (mawaho), lolo (loko) a me elua kino (ʻaoʻao). Ke frontal iwi i loko o ke kaʻina hana o ka evolution loli, e hoʻomōhala ana i frontal puu, kūpono ma me lae hoʻololi: mai ihona pali ia i lilo convex. Ke frontal ili Ua convex ma ke alo, ala apuupuu midline he mea uuku kekahi 'elevation. Ke anterior māhele o ka pā ili o na unahi komo ka orbital ili. Ke frontal iwi (ili unahi) ua kaawale mai ka ili o ka arcuate kino kino laina.

Hyperostosis o ka frontal iwi maʻi pale a Morgagni-Stewart-Morel ua ike i ka 'epekema no maluna o 250 makahiki, akā, i keia la i ka uku kuala o kānakaʻepekema a hiki i keia maʻi mau unabated. E like me ka no o keia maʻi ma laila nō ka noʻonoʻo, vegetative-vascular a me ka metabolic a me hormonal kāna hana. Kekahi i kākau i hyperostosis ka papa kuhikuhiE symptoms nā obesity, hypertension, koʻikoʻi headache. Pinepine ua hui keia maʻi me ka noʻonoʻo 'kāna hana (atrophic myotonia, cerebral kāna hana, cerebrovascular maʻi, rheumatoid maʻiʻaʻai). Eia naʻe, no laila, mamao i hookupaaia he okoa etiological ololi.

Osteoma o ka frontal iwi - he ke nānā maʻi wehewehe aku ma ke kahua o ka benign hikoko. Ua Ua manaoio aku i ka etiology o osteoma pili me ka hereditary ololi (pahiki o ka pū i hiki pathology kauoha mamo o ka 50 pakeneka), e like me ia i ho'ākāka 'congenital exostosis.

Ke pathogenesis o ka maʻi

Osteomas ikeia ekolu ano: paa, a me ka medullary huahuakai. Paa osteoma ninoieo o anuanu mea (papa), a i hoʻonohonoho ia laua a hiki i ka ili o ka neoplasm. Medullaryʻano osteoma he nui cavities i i piha me ka iwi a ka lolo.

E like me ke Virchow hoomaopopo nāʻano o nā hikoko: geteroplasticheskie (i hana mai connective'aʻaʻa), hyperplastic (i hana mai i ka iwi). Ka mua pūʻulu nā osteophytes - nīnūnē papa ma ka iwi. Inā ka mea, kūlana 'i ka holoʻokoʻa anapuni o ka iwi, e kapaia ka mea, hyperostosis. Inā iwi nuipa a ua hoopuka ia i loko o ka palapala o ka hikoko i loko o ka kaupalena makahiki, ia exostosis, ina ka mea, ua i loko o ka iwi - enostosis.

Lapaʻau hoailona osteoma

Osteomas, ka pukaʻana ma luna o ka pā ili o ka frontal iwi, pu ma pinepine headaches, ke kāʻili 'ana, hoomanao kāna hana, symptoms o ka mahuahua intracranial puʻe. Inā kaʻeho ua IIeEeAIEUIeXAIIUE i loko o ka "sella" hiki hoike hormonal imbalance. I ka IIeEeAIEUIeXAIIUE ma na sinuses wahi ua ulu diplopia, exophthalmos, ptosis, anisocoria, ua hoʻemi hihiʻo, etc.

Loa pinepine osteoma IIeEeAIEUIeXAIIUE i loko o ka pā (kīloi paʻewa) ili ana i ka iwi. Osteomas, IIeEeAIEUIeXAIIUE ma ka waho o ka puniu wale iwi papa, hoikeia mai ma ka palapala o ka hoʻonaʻauao anuanu, painless a me maoli. ʻike, ua nānā 'ana i lapaʻau a me ka radiological nā haʻina. I ka extracranialʻeho ulu ua kupikipikio hanu, nā dudima, i kekahi manawa ino lehalehu t iwi.

Akā, loa pinepine e halii mai i intracranial osteoma. Oia hikoko e luku mai i ka hope paia o ka frontal sinuses, ma o na la mīkini'opihia o ka lolo waiwai. Inā hiki i keia pathological kaʻina pili maʻiʻaʻai ulu arachnoiditis, lolo abscess, meningitis. Differentiate i ka maʻi, mai osteosarcoma a me ka osteomyelitis. i wehe surgically Neoplasms.
