Sphenoidal spine

spine of sphenoid

Intrinsic Ligaments of the Sphenoid. Posterior margin is also free and presents a small process near its centre for the attachment of pterygo-spinous ligament from the spine of sphenoid. Foramen ovale: It is a fairly large oval aperture lying posterolateral to the foramen rotundum and opens into the infra-temporal fossa. Because so few of these surgeries occur, there is little data to support statistics for success or failure. So I am not sure, but at least there seems to be agreement that antibiotics might do more harm than good in the long run. This can be terribly dangerous if it reaches the sphenoid. I do have a severe headache that has lasted seven days now.

They begin to be developed before birth, and are of a considerable size by the age of six. The anterior surface of the pterygoid process is broad and triangular near its root, where it forms the posterior wall of the pterygopalatine fossa and presents the anterior orifice of the pterygoid canal. If bony fusion takes place at an earlier age, say at 15 years, then the antero-posterior growth of the base of skull will be arrested so that the maxillary teeth of upper jaw fail to adjust with the teeth of lower jaw because the growth of the mandible takes place at the normal rate. The foramen rotundum is a circular hole in the greater wing of the sphenoid bone connecting the middle cranial fossa to the pterygopalatine fossa. Also had my house air quality checked to make sure there was no hidden invisible odorless mold or leaking carbon monoxide leaks, or radon.

Each lateral surface of the body joins with the greater wing projecting laterally and with the pterygoid process extending downward. Occasionally the carotido-clinoid ligament is converted into a bone. Pterygoid Process The pterygoid process descends inferiorly from the point of junction between the sphenoid body and the greater wing. Greater wings: Each greater wing projects laterally and then upward as a strong curved process from the side of the body. Our primary mission is to help our followers feel better, improve the quality of life without sinus disease. Lower and medial part of each concha is smooth and presents a sphenoidal foramen through which each sphenoidal sinus communicates with the spheno­ethmoidal recess of the superior meatus of nasal cavity.

Its upper and lateral margins are articular, join respectively with the orbital plate of frontal bone and the postero­medial margin of zygomatic bone. I was getting very sick, and concern that they were going to have to put me in the hospital on intravenous antibiotics. Medial to this is a triangular, serrated surface, for articulation with the frontal bone; this surface is continuous medially with the sharp edge, which forms the lower boundary of the superior orbital fissure, and laterally with the serrated margin for articulation with the zygomatic bone. Therefore, vomerovaginal canal lies above, and palatino-vaginal canal below the vaginal process. In this article, we shall look at the anatomy of the sphenoid bone — its location, structure, and clinical significance.

It started a couple of months ago with blood ,green out my nose with severe headaches when I bent my head or coughed. The sphenoid will affect all of these bones, and all of these bones will affect the sphenoid. I do not want surgery if something else can be done. In part 2 of this article, we will track what can shift the sphenoid and the possibilities for what is affected by said shift. Bilateral enlargement of parotid glands is seen without abnormal signaling. The sphenoidal conchae are each developed from a center that makes its appearance about the fifth month; at birth they consist of small triangular laminae, and it is not until the third year that they become hollowed out and coneshaped; about the fourth year they fuse with the labyrinths of the , and between the ninth and twelfth years they unite with the sphenoid bone.

The superior pharyngeal constrictor muscle attaches to the inferior end of this plate. The lateral margin of the anterior surface is serrated, and articulates with the lamina papyracea of the ethmoid, completing the posterior ethmoidal cells; the lower margin articulates with the orbital process of the palatine bone, and the upper with the orbital plate of the frontal bone. The medial joins the lateral pterygoid plate about the sixth month. Thank you for your information. This muscle tenses or elevates the soft palate during the swallowing process so food does not enter the nasopharynx. —The sphenoidal conchæ are two thin, curved plates, situated at the anterior and lower part of the body of the sphenoid. On either side of the dorsum sellæ is a notch for the passage of the abducent nerve, and below the notch a sharp process, the petrosal process, which articulates with the apex of the petrous portion of the temporal bone, and forms the medial boundary of the foramen lacerum.

The foramen spinosum is a round, small opening in the greater wing of the sphenoid located posterolateral to the foramen ovale and connecting the middle cranial fossa to the external surface of the skull. They are attachment sites for the tentorium cerebelli dura mater , which separates the cerebellum from the inferior occipital lobes of the brain. For involving sphenoid sinus, it can be extremely risky. Anterior surface of both plates is continuous and forms the posterior wall of pterygopalatine fossa which presents in the upper part the following three foramina, from lateral to medial side with downward inclination: i Foramen rotundum; ii Anterior opening of pterygoid canal; iii Palatino-vaginal or pharyngeal canal See Fig. Posterior surface of the dorsum sellae slopes downward and backward, and is continuous with the upper surface of the basi-occiput in adults to form the clivus, upon which rests the upper part of the pons. These two parts of the sphenethmoid may be distinguished as and , respectively, although there is often some degree of fusion. Between the pre- and postsphenoid there are occasionally seen the remains of a canal, the canalis cranio-pharyngeus, through which, in early fetal life, the hypophyseal diverticulum of the buccal ectoderm is transmitted.

You also need to learn basic medical facts. It would seem she considers this a bacterial infection. Numerous structures pass through here to reach the bony orbit. —The medial pterygoid plate is narrower and longer than the lateral; it curves lateralward at its lower extremity into a hook-like process, the pterygoid hamulus, around which the tendon of the Tensor veli palatini glides. The temporal surface of the greater wing of the sphenoid is the attachment site for the temporalis muscle. Rectangular abrasions on the wing tips of the sphenoid bones. However since the operation I have had severe headaches, slightly blurred vision and some loss of hearing on the affected side right.

The lateral surface of this plate forms part of the pterygoid fossa, the medial surface constitutes the lateral boundary of the choana or posterior aperture of the corresponding nasal cavity. Cell count is down, nose pours out water when turn my head upside down, Dizziness can be severe, fever off and on. Each greater wing of the sphenoid has five surfaces: cerebral, two parts of the lateral surface - temporal and infratemporal, maxillary, and orbital surfaces. In , the epipterygoids are absent and the pterygoids considerably reduced. Gerry says June 11, 2015 Tum Tum — I am female, 73. Superiorly the medial plate is prolonged on to the under surface of the body as a thin lamina, named the vaginal process, which articulates in front with the sphenoidal process of the palatine and behind this with the ala of the vomer. I felt better for the longest time — May thru July, then it returned.

The pain would only last a second at a time, and I never knew when to expect it next. He is putting me back on antibiotic. Since Cafergot contains caffeine, which is a vasoconstrictor, I take one quarter of the dosage of the 3 meds. Last night I experienced a burning sensation in the area above the eye and also in the area below the eye around the upper cheek. . —The superior surface of each is flat, and supports part of the frontal lobe of the brain.
