Sonographic Anatomy and Imaging of the Extracranial Component of the Hypoglossal Nerve (CNXII)

open access: yesJournal of Medical Radiation Sciences, EarlyView.
The hypoglossal nerve (HN) provides motor innervation to tongue muscles responsible for tongue movement, speech, mastication, swallowing, respiratory functions and management of oral secretions. The intracranial component of the HN can be demonstrated on magnetic resonance imaging and the extracranial component can be demonstrated with sonographic ...

Tic douloureux in patients with incidental intracranial meningioma; MR findings and review of literature

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2015
Patients with trigeminal neuralgia undergo various investigations in-order to rule-out suspected underlying causes. MRI has proven to be the imaging modality of choice when trigeminal nerve pathology is suspected; it also provides useful guidance in ...

Imaging Characteristics of Persistent Carotid‐Vertebrobasilar Anastomoses Detected by Ultrasound

open access: yesJournal of Ultrasound in Medicine, EarlyView.
In this case series, we aimed to evaluate the ultrasonic characteristics of 35 patients with persistent carotid‐vertebrobasilar anastomoses (PCVBA), a rare variant between the anterior and posterior cerebral circulation. Ultrasound detected seven (30.4%, 7/23) primitive trigeminal arteries (PTA), eight (100%, 8/8) primitive hypoglossal arteries (PHA ...

Cues from neuroepithelium and surface ectoderm maintain neural crest-free regions within cranial mesenchyme of the developing chick [PDF]

open access: yes, 2002
Within the developing vertebrate head, neural crest cells (NCCs) migrate from the dorsal surface of the hindbrain into the mesenchyme adjacent to rhombomeres (r)1 plus r2, r4 and r6 in three segregated streams.

Mechanisms of Improving Feeding Function With Capsaicin Following Local Anesthesia in Infant Pigs

open access: yesThe Laryngoscope, EarlyView.
With inferior alveolar nerve anesthetization, we found changes in some behavioral variables, as well as a decrease in bolus sizes and improved airway protection. This highlights the tradeoff between feeding efficiency and feeding safety. With capsaicin administration, some behavioral variables were returned to baseline values fully or partially, which ...

Perceiving Smellscapes [PDF]

open access: yes, 2020
We perceive smells as perduring complex entities within a distal array that might be conceived of as smellscapes. However, the philosophical orthodoxy of Odor Theories has been to deny that smells are perceived as having a distal location.

Surgical Management of a Cerebellopontine Angle Tumor After Sudden Onset Facial Paralysis

open access: yesThe Laryngoscope, EarlyView.
Patients with cerebellopontine angle tumors rarely experience acute facial weakness. In this report, we summarize a case where immediate tumor decompression after a patient presented with sudden ipsilateral flaccid facial palsy resulted in complete recovery of facial nerve function, followed by staged gross total tumor resection. Return of facial nerve
