Exempel på ethmoid

• Craniofacial skeletal sequelae with these severe phenotypes are compatible with loss of frontonasal process derivatives, such as the ethmoid, nasal bones and premaxilla.

• Both lateral ethmoids extend laterally beyond the frontal profile in dorsal view, but this condition is probably due to the crushing of the specimen.

• The precise structure of the ethmoid region cannot be determined.

• The shape of the nose is determined by the ethmoid bone and the nasal septum, which consists mostly of cartilage and which separates the nostrils.

• The ethmoid fracture can produce bone fragments that penetrate the cribriform plate.

• The lacrimal duct, nasal bone, nasal cavity, vomer, maxillary sinus, cribriform plate, and ethmoid cells are often missing on the involved side.

• This involves penetrating three separate sinus cavities: the ethmoid sinus, the sphenoidal sinus, and the maxillary sinus.

• This procedure is often successful in the removal of small encephaloceles of the ethmoid osteomas of the ethmoid sinus wall or small olfactory groove meningiomas.

• The porous, fragile nature of the ethmoid bone makes it particularly susceptible to fractures.

• The irregular bones are: the vertebr, sacrum, coccyx, temporal, sphenoid, ethmoid, zygomatic, maxilla, mandible, palatine, inferior nasal concha, and hyoid.

• The human palatine articulates with six bones: the sphenoid, ethmoid, maxilla, inferior nasal concha, vomer and opposite palatine.

• The former involve the occipital bone, temporal bone, and portions of the sphenoid bone; the latter, superior portions of the sphenoid and ethmoid bones.

• Its posterior margin is connected with the perpendicular plate of the ethmoid; its inferior margin with the vomer and the palatine processes of the maxillae.

• Large hematomas usually start within the ethmoid labyrinth, and smaller ones tend to begin on the sinus floor.

• The origins and causes of the ethmoid hematoma are generally unknown.
