	II. Osteology. 5a. 3. The Frontal Bone. Gray, Henry. 1918. Anatomy of the Human Body.
		The frontal bone resembles a cockle-shell in form, and consists of two portions—a vertical portion, the squama, corresponding with the region of the forehead; and an orbital or horizontal portion, which enters into the formation of the roofs of the orbital and nasal cavities.
		The superior surface is convex, and marked by depressions for the convolutions of the frontal lobes of the brain, and faint grooves for the meningeal branches of the ethmoidal vessels.
		The anterior canal transmits the nasociliary nerve and anterior ethmoidal vessels, the posterior, the posterior ethmoidal nerve and vessels.

	Ethmoid bone - Wikipedia, the free encyclopedia
		The ethmoid bone (os ethmoidale) is a bone in the skull that separates the nasal cavity from the brain.
		The ethmoid bone (os ethmoidale) 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.
		The anterior border articulates with the spine of the frontal bone and the crest of the nasal bones.

	Solitary plasmocytoma of frontal bone presenting as an asymptomatic forehead lump
		We present a case of a solitary extramedullary plasmacytoma of the frontal bone presenting as an asymptomatic forehead lump with clinically benign characteristics.
		Hispathological examination of the excised specimen confirmed the diagnosis of plasmacytoma of the frontal bone.
		Solitary bone plasmacytoma is an uncommon form of plasmacytoma and is localized to the involved bone [1].

		The last piece of cartilage to ossify is between the body of the sphenoid bone and the occipital bone, anterior to the foramen magnum: this is the spheno-occipital synchondrosis (the epiphyseal plate for growth in length of the base of the skull and it ossifies at age 25).
		The parietal bones are separated by the sagittal suture and from the frontal bone by the coronal suture.

		Bone rongeurs are used to extend the circular osteotomy and expose ethmoidal conchae.
		A bone trephine may be used to perform the sinusotomy rostral to a location that parallels the zygomatic processes of the frontal bone.
		The sinusotomy may be enlarged using bone rongeurs to expose the caudal nasal passages for sinus drainage or greater areas of frontal sinus for sinus obliteration or reconstruction of the nasofrontal opening.

		The frontal bone may be divided into two main portions, a vertical squamous portion which articulates with the paired parietals along the Coronal Suture and forms the forehead, and two orbital plates, which contribute to the ceiling and lateral walls of the left and right eye orbits.
		With in the bone, and above and the metopic suture, is the Frontal Sinus.
		The left and right Frontal Crest, begins at each Zygomatic Process of the frontal bone, and provides the anterior origin of the Temporal Line to which the left and right temporal muscle is attached.

		Suture dividing the frontal bone from the upper maxilla and the cuneiform.
		The portion from R to S marks the part of the suture common to the frontal bone and the first bone [os zygomaticum] of the maxilla; it is seen in the hollow of the temple [fossa temporalis] in the third figure of the sixth chapter, extending there from b to the b next to it.
		Then, the fourth bone is terminated by the sutures separating it from the second [os lacrimale] and third [os ethmoidale] maxillary bones; these sutures (from X along C to c, then to d) run the entire length of the lower part of the eye socket and in the anterior region of the second maxillary bone.

	Features of Human Cranium - Atlas of Human Skull Bones and Facial Bones
		The human cranium and the facial bones are the foundation for the soft tissues of the face and head.
		The important facial bones include the jaw bone or mandible, the maxilla or upper jaw, the zygomatic or cheek bone, and the nasal bone.
		Processes are areas where the bones have extra tissue to hold muscles and ligaments; lines are grooves in the bone from other developmental processes; foramina are holes in the bones through which nerves and blood vessels pass; sinuses are empty spaces in the bones that make the skull lighter.

		Anatomically the frontal sinus is a pyramidal shaped structure with vertical and horizontal segments in the frontal bone.
		It borders the anterior cranial fossa and the roof of the orbit.
		The etiology of frontal sinusitis stems from blockage of the nasofrontal duct ostium.

		Nasal Region Close-Up Mandible Close-Up The skull is comprised of two main groups of bones, the cranial bones which form the cranium (a set of bones that forms the box enclosing the brain) and the facial bones (the bones comprising the anterior surface of the skull including the jaw).
		The frontal bone forms the anterior portion of the cranium commonly referred to as the forehead.
		Areas of the frontal bone just lateral to the glabella are filled with rather large cavities called the frontal sinuses.

	Frontal Bone (Site not responding. Last check: 2007-08-19)
		The "frontal bone" forms the front portion of the skull above the eyes and includes the forehead, the roof of the nasal cavity, and the roofs of the orbits (bony sockets) of the eyes.
		On the upper margin of each orbit, the frontal bone is marked by a "supraforamen" or ("suproorbital notch" in some skulls), through which blood vessels and nerves pass to the tissues of the forehead.
		Within the frontal bone are two "frontal sinuses," one above each eye near the midline.

		DD:.there is apparently absence of bone anterior to this line, with the absence present to a point approximately equivalent to where the coronal suture on the right side should be.
		This fracture seems to extend into the frontal bone, more or less at the midline, down to the frontal sinus which is also fractured.
		DD: There is a fracture fragment inferior to the absent bone, with the corner of the fragment extending down to the parietal squamosal suture, and this fragment is displaced from its normal position as indicated by overlap of the infero and posterior aspects of the fracture fragment.

		The overlying soft tissue was dissected free from the bone exposing the entire anterior iliac crest and the medial and lateral cortical walls.
		Following the cadaver study, the trephine was used to harvest bone in a total of 149 patients requiring autologous free grafts for various augmentation procedures: 11 patients in study I, 84 patients in study II, and 54 patients in study III.
