Type 1 is the spheno-parietal type, irregular H like-shaped suture, formed by articulation of the frontal, parietal, greater wing of the sphenoid
and the squamous part of temporal bones.
Foreign body within sphenoid
sinus: Multidetector-row computed tomography (MDCT) demonstration.
In the skull, sphenoid
and frontal bones are affected.
6,7] This case report presents the case of a sphenoid
wing meningioma in a patient who presented with cognitive impairment.
Involvement of the infratemporal fossa or sphenoid
sinus is common, with each occurring in roughly two-thirds of patients (n = 5, 71%).
2) These include: the infundibular pattern, with inflammation of the maxillary sinus and opacification of the ipsilateral ostium and infundibulum; the ostiomeatal unit pattern, with inflammation of the ipsilateral maxillary, frontal and ethmoid sinuses and occlusion of the middle meatus (Figure 1); the sphenoethmoidal recess pattern, with obstruction of the sphenoethmoidal recess and inflammation of the ipsilateral posterior ethmoid and sphenoid
sinuses; the sinonasal polyposis pattern, which is characterized by the diffuse presence of polyps in the paranasal sinuses and nasal cavity; and the sporadic pattern, also termed unclassifiable, which is diagnosed when there is random sinus disease not related to ostial obstruction or polyposis.
Study of Sphenoid
Sinus Anatomy in Relation to Endoscopic Surgery" Int.
sinusitis is an uncommon condition that comprises less than 3% of all cases of sinusitis.
Other unlisted and unexpected incidental anatomical variations included; pneumatized uncinate process in three films, pnuematized superior turbinate in CT (n = 5), the presence of septations adjoining the carotid in the lateral wall of the sphenoid
or posterior ethmoids and exposure of the optic nerve within the posterior ethmoid and sphenoid
(n = 3).
We describe a patient with an aggressive follicular variant of papillary thyroid carcinoma who presented with an unusual metastasis to sphenoid
Paranasal mucoceles are most commonly found in the frontal sinus, and are occasionally found in the ethmoid and sphenoid
I then used a gloved finger to palpate her vomer, a small bone that articulates with the soft palate and sphenoid
, which was restricted and which released while Ali sucked on my finger.
As a result, the ethmoid air cells are rarely limited to the lateral ethmoid masses; they often extend into the turbinates, crista galli and the neighbouring frontal, maxillary, sphenoid
and palate bones.
htm) a cerebrospinal fluid leak -- where her sphenoid
sinus was cracked in two places.
Among the topics are imaging in endoscopic sinus surgery, sphenopalatine artery ligation and vidian neurectomy, the endoscopic resection of pituitary tumors, the anatomy of the sphenoid
and adjacent structures of importance during skull base surgery, and endoscopic surgery of the cranocervical junction.
