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 e pili ana i ka maka, ka orbital a me retrobulbar fascia, nā ʻiʻo extraocular, nā aʻalolo cranial, nā kīʻaha koko, ka momona, ka lacrimal gland me kona ʻeke a me kāna ʻāʻī, nā lihilihi, medial a me lateral palpebral ligaments, nānā i nā ligaments, ka ligament suspensory, septum , ciliary ganglion and short ciliary nerves.

ʻO nā ʻōpuni he ʻano conical a i ʻole ʻehā ʻaoʻao pyramidal cavities, e hāmama ana i ka waena waena o ke alo 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 ʻano embryologically ʻokoʻa. , ka iwi maxillary ma lalo a ma waena, me ka iwi lacrimal a me ka iwi ethmoid, ka paia waena o ka canal 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 ka zygomaticosphenoid suture.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 orbital repair implant material koho, pono nā mea implant implant i kēia mau hiʻohiʻona: maikaʻi biological compatibility, maʻalahi e hoʻohālikelike a waiho ʻia i loko o nā ʻāpana kīnā o ka paia orbit, hiki ke maʻalahi ke hoʻopaʻa i kona ʻano i kākoʻo i nā mea orbital i mālama i ke kūlana maʻamau, hiki ke hoʻololi. ka nalo ʻana o nā mea orbital a hoʻonui i ka volume orbital cavity, hoʻonui CT volume e hoʻomaʻamaʻa i ka nānā ʻana ma hope o ka hana.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 paia 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.
