Dehiscence of the lamina papyracea is an anomaly of the ethmoid that was identified long ago on skull dissections (2, 3). In the present study we describe six cases noted. cases. Following the ribs and long bones, craniofacial bones are the second most common site of involvement and comprise 25% of the cases. Among FD of the head and neck, the maxilla and mandible are the most frequent sites to be involved, followed by the frontal, parietal and occipital bones. However, FD of the paranasal sinuses is very rare The ethmoid bone is located between the nasal bones of the face and has the following features: • It forms the crista galli on top (superiorly) - the cocks comb. • It forms the cribriform plate (a horizontal plate beneath the crsita galli) Ethmoid bone is a pneumatic bone; contain the ethmoid air cells (ethmoid paranasal sinus) which drain into superior and middle nasal meatus.

In most mammals, the nasal chamber is large & filled with ridges from the ethmoid bones called the turbinals or ethmoturbinals. These bones are covered with olfactory epithelium in life and serve to increase the surface area for olfaction (i.e., a more acute sense of smell) Image of a patient with fracture nasal bone associated with deviation of dorsum of nose 6. Nasal bones undergo fracture in its lower portion and seldom the upper portion is involved in the fracture line. This is because the upper portions of the nasal bone is supported by its articulation with the frontal bone and frontal process of maxilla. 7

Ethmoid bone. The ethmoid bone is a single midline facial bone that separates the nasal cavity from the brain and is located at the roof of the nose and between the orbits. It is a cubical shape and is relatively lightweight because of its spongy construction. It contributes to the anterior cranial fossa Embryologically the ethmoid is different from all the other sinuses. The ethmoid bone originates from the car-tilaginous nasal capsule or paleosinus (endochondral bone), whereas the other paranasal sinuses are exten-sions from the ethmoid (extracapsular) into membranous bone (neosinus) via epithelial diverticula extensions

In a study of th The ethmoid bone forms the anterior floor of the cranium. It articulates with the underside of the frontal bone, extending inferiorly and posteriorly behind the nose. The ethmoid bone also forms a portion of each orbit. The sphenoid bone is a complex bone that makes up part of the floor of the cranium and also portions of its lateral outer shell Ethmoid bone. The ethmoid bone separates the nasal cavity from the brain. It forms part the perpendicular plate of the osseous nasal septum. It also contains small foramen that allow the olfactory nerve to move from within the skull to the top of the nasal cavity to sample air particles. This part of the ethmoid bone is called the cribriform plate ethmoid bone gave rise to important pathogenetic considerations, an endoscopic diagnostic concept, and a subsequent approach to functional endoscopic sinus surgery (F.E.S.S.), to date there have been no fundament - al studies on the stabilizing function of the principal ethmoid cells

The first defines them as the most posterior ethmoid cells, being superolateral to the sphenoid sinus and closely associated with the optic nerve. Another, more general description defines Onodi cells as posterior ethmoid cells extending into the sphenoid bone, situated either adjacent to or impinging upon the optic nerve 53 Ethmoid sinusitis is the inflammation of a specific group of sinuses — the ethmoid sinuses — which sit between the nose and eyes.

Palatine bone (Os palatinum) The palatine bone is a paired bone located between the maxillae and the pterygoid process of the sphenoid bone.It participates in building the three cavities within the skull; the oral cavity, nasal cavity and the orbits.It does so by articulating with five bones; maxilla, sphenoid, ethmoid, inferior nasal concha, and vomer Ethmoid sinusitis is an uncomfortable condition that can be treated as well as prevented. If sinusitis symptoms go on for more than a few days, a doctor will likely prescribe antibiotics to help. An osteoblastoma is a benign bone tumor that most often occurs in the vertebral column and the long bones of the extremities. Paranasal sinus involvement is very rare. We report an osteoblastoma of the ethmoid sinus in a 13-year-old boy who presented with exophthalmos. CT demonstrated an expansile, lesion of the right ethmoid sinus, which caused the orbital contents to be compressed and. The ethmoid bone is exceedingly light and spongy, and cubical in shape; it is situated at the anterior part of the base of the cranium, between the two orbits, at the roof of the nose, and contributes to each of these cavities. It consists of four parts: a horizontal orcribriform plate, forming part of the base of the cranium; a perpendicular.

The ethmoid bone and lacrimal bone make up much of the medial wall and the sphenoid bone forms the posterior orbit. At the posterior apex of the orbit is the opening of the optic canal, which allows for passage of the optic nerve from the retina to the brain. Lateral to this is the elongated and irregularly shaped superior orbital fissure. the CT features of focal hyperostosis, 2 patterns of localized bone thickening were noted. Plaquelike bone thickening was seen mainly when focal hyperostosis involved the lateral wall of the nasal cavity. On the other hand, cone-shaped bone thickening was seen only in the walls of the paranasal sinuses or the bony septum

Ethmoid sinus cancer may spread rapidly to the adjacent areas, especially because of the fact that the early disease is frequently asymptomatic. Unfortunately, this also means that the Cancer involving the ethmoid sinus alone is a rare entity. In majority of cases, by the time Ethmoid sinus cancer is detected, it has already reached advanced stage The sphenoid bone is the most complex bone of the human body.Because of its shape, it is also known as the wasp bone. It makes up most of the middle part of the base of the skull and contributes to the floor of the middle cranial fossa of the skull.. The soft tissue structures such are the cranial nerves and parts of the brain are associated with this bone and have intense relations to it Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes — the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a.

The orbits are the bony recesses that enclose and protect the eyes. The orbital complex consists of the bones that form the orbit and include the maxilla, lacrimal bone, ethmoid, palatine bone, sphenoid, frontal bone and zygomatic bone 5. Due to the number of cells within the ethmoid sinus, it is the most difficult to segment. You will likely often have to switch between the segmentation tool and the paint tool. 6. You can then create a 3-D model of the ethmoid sinus

The zygomatic bone functions as a structure which joins the bones of the face while protecting the arteries, nerves, veins, and organs which lie below the surface. The arches of the zygomatic bone provide a person's cheeks with the structure to fill out the face. The zygomatic bone itself has no ability to move, as it is a stationary bone. Facial Bones.

The ethmoid bone separates the orbit from the ethmoid sinus. Lateral wall - Formed by the zygomatic bone and greater wing of the sphenoid. Apex - Located at the opening to the optic canal, the optic foramen. Base - Opens out into the face, and is bounded by the eyelids. It is also known as the orbital rim Zygomatic bone, also called cheekbone, or malar bone, diamond-shaped bone below and lateral to the orbit, or eye socket, at the widest part of the cheek. It adjoins the frontal bone at the outer edge of the orbit and the sphenoid and maxilla within the orbit. It forms the central part of the zygomatic arch by its attachments to the maxilla in front and to the zygomatic process of the temporal. The human skull comprises of the ethmoid bone which is a singular porous bone that forms the midfacial region of the skull. It adds to the molding of the nasal septum orbit and the nasal cavity.
