A frontal kashi kunshi sassa hudu: biyu orbital, hanci da kuma frontal ma'auni. Frontal surface yana da wadannan ma'aunan: frontal (m), kwakwalwa (ciki) da kuma biyu na boko (gefen). A frontal kashi a cikin tsarin juyin halitta canje-canje, tasowa frontal mounds, sakamakon sanyi goshi canza: daga downhill ya zama convex. A frontal surface ne convex a gaban, m midline akwai kadan m tadawa. A cikin agara sassa na matsanancin surface na da Sikeli shiga orbital surface. A frontal kashi (surface Sikeli) da aka rabu da surface na arcuate boko boko line.

A sakamakon wannan cuta akwai shafi tunanin mutum, vegetative-jijiyoyin bugun gini da kuma na rayuwa da kuma hormonal cuta. Wasu mawallafa to hyperostosis babban bayyanar cututtuka sun hada da kiba, hauhawar jini, m ciwon kai. Sau da yawa da wannan cuta da aka hada tare da shafi tunanin mutum da cuta (atrophic myotonia, cerebral cuta, cerebrovascular cuta, rheumatoid kamuwa da cuta). Duk da haka, ya zuwa yanzu ba a kafa wani jinsin etiological factor.

Osteoma na frontal kashi - a rare cuta halin da samuwar benign siffofin maruran. An yi imani da cewa etiology na osteoma dangantawa da hereditary factor (Yiwuwar yada Pathology kai tsaye zuriyar kashi 50), kamar yadda aka bayyana nakasar exostosis.

A pathogenesis da cutar

Osteomas sani iri uku: m, kuma medullary soso. M osteoma kunshi m abu (faranti), wanda aka shirya a layi daya zuwa surface wani neoplasm. Medullary irin osteoma ƙunshi m cavities wanda suna cike da bargo.

A cewar Virchow rarrabe iri biyu marurai: geteroplasticheskie (kafa daga connective nama), hyperplastic (kafa daga kashi). Na farko da kungiyar hada osteophytes - qananan yadudduka a kashi. Idan suka zauna dukan karkara na kashi, aka kira su hyperostosis. Idan kashi taro da aka bayar a cikin nau'i na marurai a cikin iyaka sarari, shi exostosis, idan an dauke a cikin kashi - enostosis.

Clinical ãyõyi osteoma

Osteomas, kunno kai a ciki surface na frontal kashi, tare da m ciwon kai, seizures, memory cuta, cututtuka da ya karu intracranial matsa lamba. Idan ƙari da aka sarrafa a cikin "sella" iya tabbatar da hormonal rashin daidaituwa.
