Ophthalmic artery is the branch of internal carotid artery as it emerges from the cavernous sinus medial to anterior clinoid process. Thereafter it traverses in optic canal to enter in the orbit, lies inferolaterally to the optic nerve. It continues forward over the optic nerve (80%) and below the nerve (20%). Main trunk of the artery ends by dividing in to supratrochlear and dorsal nasal branc...

background: role of atherosclerosis  in the pathogenesis of ischemic and hemorrhagic  infarctions is still matter  of debate. intima-media thickness (imt) of the common carotid  artery (cca) and  internal  carotid  artery (ica) are markers of atherosclerosis. the aim of this study was to compare  cca imt and ica imt of patients  with ischemic and hemorrhagic infarction. methods: two equal group...

Background and Objective: Vocal cord paralysis results in impairment of breathing and/or speech. One the causes vocal is disruption vagus nerve innervation to cords by mass effect a neighbouring structure. We report rare case secondary internal carotid artery dissection. Method: The diagnosis was based on clinical history, physical examination imaging studies. Literature review done. Case Repor...

We evaluated the ability of dynamic CT scanning to accurately demonstrate the laterosellar extradural venous spaces. Careful examination of 680 consecutive patients with this technique has permitted us to describe four main venous groups: the veins of the lateral wall (present in 98% of cases), the vein of the inferolateral group located beneath cranial nerve VI (present in 92% of cases), the m...

Correspondence To the Editor: Carotid body tumor (CBT) is a highly vascular neoplasm of neural crest origin arising in paraganglial cells of the carotid bifurcation. Branches from external carotid artery or glomic artery arising at the bifurcation of common carotid artery dominate in the blood supply mode. Only very few cases with supplementary blood supply from an internal carotid artery (ICA)...

OBJECTIVES/HYPOTHESIS To illustrate detailed anatomy of the extracranial portion of the glossopharyngeal nerve in the parapharyngeal space as encountered during transoral surgery. STUDY DESIGN Prospective cadaveric dissection. All dissections were performed transorally and confirmed with transcervical dissection. METHODS Eight color-injected cadaveric heads (16 sides) were dissected to demo...

A 14-year-old Thai boy presented because of a history of headache, mandibular swelling, and facial nerve palsy. A microorganism identified as Pythium insidiosum was cultured from the mandibular abscesses. Despite treatment with amphotericin B, iodides, ketoconazole, and surgery, the infection progressed. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the neck revea...

The location of the original sites of the lesions was studied in 22 non-traumatic and 21 traumatic intracavernous carotid aneurysms in which the neck of the aneurysm was confirmed, and also in 23 traumatic carotid-cavernous fistulas in which the location of the fistula was identified. In the cavernous sinus, common sites of non-traumatic and traumatic carotid aneurysms as well as traumatic caro...
