Frontal pfupa: anatomi uye zvokurwara

The frontal pfupa anoumba calvarium. Rinobatanidzwa ne pfungwa (kuona uye kunhuwidza), kuita munhu hunyambiri basa, uye ine zvikamu zviviri: chinjikira uye tote. Horizontal dhipatimendi rakakamurwa unpaired nasal uye orbital zvikamu chiutsi.

The frontal pfupa ine zvikamu zvina: zviviri orbital, nasal uye frontal pachiyero. Frontal penyika ine zvinotevera chikero: frontal (yokunze), uropi (yomukati) uye vaviri nezvenyama (divi). The frontal mapfupa ari mubishi yemhindumupindu kuchinja, anova frontal pazvikomo, zvichiguma inotonhorera huma kushanduka kubva downhill akava convex. The frontal penyika iri convex pamberi, mvere midline hapana oneka pakakwirira. The Anterior zvikamu rokunze pose pachikero anopinda orbital pamusoro. The frontal pfupa (pamusoro chikero) anosiiwa pemvura arcuate rwenyama rwepanyama mutsetse.

chirwere

Hyperostosis of frontal pfupa chirwere kana Morgagni-Stewart-Morel nesayenzi kweanodarika makore 250, asi kunyange nhasi kufarira masayendisiti kuti chirwere ichi mberi vachimuvenga zvokutoda kumuponda. Somugumisiro chirwere ichi pane pfungwa, vegetative-vascular uye metabolic uye hormone zvirwere. Vamwe vanyori kuti hyperostosis chikuru zviratidzo zvinosanganisira kufutisa, BP, kuramba nomusoro. Kazhinji chirwere ichi unobatanidzwa chirwere chepfungwa (atrophic myotonia, chepfungwa zvirwere, cerebrovascular chirwere, RA chirwere). Zvisinei, saka kure haana kusimbiswa vaakasarudza etiological chinhu.

Osteoma of frontal mapfupa - isingawanzowanikwi chirwere dzinoratidzwa paumbwe benign anomera. Zvinonzi vaidavira kuti etiology kuti osteoma chokuita nenhaka chinhu (ndingangokuvara kuparadzira zvokurwara zvakananga vazukuru 50 muzana), sezvinorondedzerwa vachiberekwa exostosis.

The pathogenesis chirwere

Osteomas anozivikanwa mhando nhatu: zvikukutu, uye medullary chipanje. osteoma Hwakasimba ine gobvu zvinhu (nemahwendefa), izvo akaronga akaererana pose ari neoplasm. Medullary mhando osteoma rine zvakawanda in ayo akazara mwongo.

Maererano Virchow kusiyanisa nezvemarudzi maviri anomera: geteroplasticheskie (aumba kubva connective zvinyama), hyperplastic (aumba kubva mafupa). Boka rokutanga rinosanganisira osteophytes - vaduku akaturikidzana panguva mafupa. Kana anogara rose sekamufarenzi pakati pfupa, dzinonzi hyperostosis. Kana pfupa gobvu wakabudiswa muchimiro anomera munzvimbo shoma nzvimbo, zvinoita exostosis, kana zviri mukati pfupa - enostosis.

Clinical zviratidzo osteoma

Osteomas, hwava pamusoro romukati pemvura frontal pfupa, achiperekedzwa kakawanda nomusoro, nezvipusha, ndangariro zvirwere, zviratidzo yakawedzera intracranial kumanikidzwa. Kana bundu iri mupasi mu "sella" anogona kuratidza hormone kusaenzana. Kana vemunyika vari sinuses nzvimbo kunokudziridzwa diplopia, exophthalmos, ptosis, anisocoria, ungaderedza chiratidzo, etc.

Kakawanda osteoma vemunyika kuruvazhe (lateral) pechiso mafupa. Osteomas, vemunyika pamusoro kunze dehenya mapfupa ndiro, richiratidzwa muchimiro gobvu, nyarara uye chaiyo dzidzo. Chirwere pazvikanganiso kurapwa uye radiological zvakawanikwa. Kana extracranial bundu kukura akashatirwa kufema, kunhuwidza, dzimwe nguva akaremara chiso marangwanda.

Asi kazhinji kuparadzira intracranial osteoma. namamota yakadaro aparadza rwemberi rusvingo frontal sinuses, kukonzera compression uropi fuma. Kana iri pathological muitiro akabatanidza chirwere kuva arachnoiditis, pfungwa pute, yomumuzongoza. Kusiyanisa chirwere kubva osteosarcoma uye osteomyelitis. Neoplasms vanobviswa surgically.
