papa papa orbital anatomical

Ma ke anatomy, ʻo ka orbit ka lua a i ʻole ke kumu o ka iwi poʻo kahi i kū ai ka maka a me kona mau ʻāpana. "Orbit" hiki ke kuhikuhi i ke kumu iwi. ʻO ka nui o ka orbit i ke kanaka makua he 30 milliliters, noho ka maka i 6.5 ml o ka nui. ʻO nā mea orbital ka maka, ka orbital a me retrobulbar fascia, extraocular muscles, cranial nerves, blood vessels, fat, the lacrimal gland with its sac and duct, the eyelids, medial and lateral palpebral ligaments, check ligaments, the suspensory ligament, septum, ciliary nerve ganglions and short nerve ganglions.

ʻO nā ʻōpuni he ʻano conical a i ʻole ʻehā ʻaoʻao pyramidal cavities, wehe ʻia i ka waena waena o ka maka a kuhikuhi hou i ke poʻo. He kumu, he piko a me nā paia ʻehā i loko o kēlā me kēia orbit.

ʻO nā paia iwi o ke awāwa orbital i loko o ke kanaka he mosaic o ʻehiku mau embryologically ʻokoʻa, ʻo ia ka iwi zygomatic ma ka ʻaoʻao, ka iwi sphenoid, me kona ʻēheu liʻiliʻi e hana ana i ka canal optic a ʻo kona ʻēheu nui e hana ana i ka ʻaoʻao hope o ke kaʻina orbital iwi, ʻo ka iwi maxillary me ka ʻaoʻao o lalo a me ka medially. paia o ke kahawai orbital. He lahilahi loa nā ʻea ethmoid, a he ʻano i kapa ʻia ʻo ka lamina papyracea, ka ʻili iwi ʻoi loa o ka iwi poʻo, a ʻo kekahi o nā iwi haʻihaʻi maʻamau i ka trauma orbital.

Hoʻokumu ʻia ka pā ʻaoʻao e ke kaʻina mua o ka zygomatic a ʻoi aku ma hope e ka pā orbital o ka ʻēheu nui o ka sphenoid. Hui nā iwi ma ke kuʻi zygomaticosphenoid. ʻO ka paia ʻaoʻao ka pā mānoanoa loa o ka orbit, ʻo ia ka ʻili i ʻike nui ʻia, no laila maʻalahi ke hālāwai ʻana i nā mea palupalu i ka trauma ikaika.

ʻO ka haʻihaʻi o ka paia orbital haʻahaʻa ka haʻihaʻi maʻamau i ka haʻihaʻi orbital blowout, kahi e hoʻopiʻi pinepine ai e like me ka enophthalmic invagination, ka maʻi ocular neʻe ʻana, ka diplopia a me ka neʻe ʻana o ka ocular, e hoʻopilikia nui i ka hana a me ka helehelena. No nā haʻihaʻi orbital blowout, pono e hana ʻia ke ʻoki i ka wā hiki ke ʻoi aku ka invagion intraocular ma mua o 2mm a ʻoi aku ka nui o ka ʻāpana haʻi e like me ka hōʻoia ʻana e CT. I ka hoʻoponopono ʻana i ka haʻihaʻi orbital, ʻo nā mea hana maʻamau i hoʻohana ʻia me ka iwi artificial hydroxyapatite, porous polyethylene polymer synthetic material, hydroxyapatite complex a me nā mea metala titanium. No ka hoʻoponopono orbital implant material koho, pono nā mea implant implant e loaʻa i kēia mau hiʻohiʻona: maikaʻi kūlohelohe maikaʻi, maʻalahi ke hoʻohālikelike ʻia a waiho ʻia i nā ʻāpana kīnā o ka pā orbit, hiki ke maʻalahi i ka mālama ʻana i kona ʻano i kākoʻo i nā mea orbital i mea e mālama ai i ke kūlana maʻamau, hiki ke hoʻololi i ka nalo ʻana o nā mea orbital a hoʻonui i ka nui o ka orbital cavity, hoʻonui ka nānā ʻana i ka CT. Ma muli o ka maʻalahi o ka titanium mesh a loaʻa ka hoʻoponopono maikaʻi, ʻaʻohe ona sensitization, carcinogenesis a me teratogenicity i ka pilina me ke kino kanaka, a hiki ke hui maikaʻi ʻia me ka iwi iwi, epithelium a me nā mea pili, no laila ʻo ia ka mea metala maikaʻi loa me ka biocompatibility.

Hoʻolālā ʻia nā Papa Orbital Preformed mai ka ʻikepili CT scan. Aia kēia mau papa i nā implants e pili kokoke ana i ka anatomy topographical o ka papahele orbital kanaka a me ka pā medial a ua manaʻo ʻia no ka hoʻohana ʻana i kahi trauma craniomaxillofacial koho. ʻO ke ʻano ʻekolu-dimensional i hana mua ʻia: Hoʻolālā ʻia no ka liʻiliʻi liʻiliʻi a me ka ʻoki ʻana e hōʻemi ana i ka nui o ka manawa e pono ai ka contour plate. Nā ʻaoʻao pā i hoʻohālikelike ʻia: No ka hoʻokomo ʻana i ka pā ma o ka ʻoki ʻana i ka ʻili a me ka liʻiliʻi o ka hoʻopili ʻana ma waena o ka pā a me nā ʻiʻo palupalu a puni. Hoʻolālā ʻāpana: E hana i ka nui o ka pā e hoʻoponopono i ka topography orbital a me ka mālama ʻana i nā palena o ka pā me nā kihi ʻoi liʻiliʻi. Wahi ʻoʻoleʻa: Hoʻihoʻi i ke ʻano i ka papahele orbital hope e kōkua i ka mālama ʻana i ke kūlana kūpono o ka honua. nā hāʻina piha no ka hoʻoponopono ʻana a me ka hana hou ʻana o ka papahele orbital.
