These comprised 2 o 4 branches which arise from each side of the basilar
With respect to the outer ear occlusion effect (mechanism 1) and middle ear ossicle inertia (mechanism 2), the pressure difference across the basilar
membrane, inducing its displacement, is a result of the vibrations of the tympanic membrane (occlusion effect) or of the stapes footplate (ossicle inertia), which act inward to the inner ear, as in AC.
La mayoria de las alteraciones oseas del axis no tiene relacion con invaginacion basilar
, es mas las mas frecuentes el "os terminal" o el "os odontoideum" que es una falla de fusion del nucleo de osificacion del diente conocido como osiculo de Bergman, puede confundirse con una fractura de odontoides Tipo 1.
Sixteen consecutive patients (14 males and 2 females; age, 54-67 years; mean age, 61.9[+ or -]3.9 years) with basilar
artery atherosclerosis were prospectively recruited from February 2014 to July 2014.
The absence of atheromatous plaques in the posterior circulation (patency of the vertebral arteries, basilar
, and left PCA) and the lack of clotting disorder have argued against an arterial embolization.
Confocal images of the basilar
membrane showed that the stereocilia and hair cells of the wild-type and Myo3a mutant mice were intact at the age of 2 months; by contrast, the stereocilia of the Myo3a mutant mice started to degenerate, and the hair cells began to disappear at 6 months.

skull fractures (Review)," The Cochrane Database of Systematic Reviews, vol.
Jun-Hyuk Kwak, Youngdo Jung, and Kyungjun Song designed the artificial basilar
membrane, performed experiments and analysis, and wrote the manuscript.
Head CT (Figure 1) showed 1.5 cm right panhemispheric hyperdensity in the subdural space with significant midline shift, falcine herniation, uncal herniation, and loss of basilar
Meta-analysis revealed that acupuncture can increase more significantly Vm of left vertebral artery (MD: 2.86; 95% CI: 1.25-4.46; P = 0.0005), right vertebral artery (MD: 3.52; 95% CI: 1.52-5.51; P = 0.0006), and basilar
artery (MD: 2.60; 95% CI: 1.42-3.79; P < 0.0001) compared with medication.
In histopathologic study, basilar
artery (BA) atherosclerosis plaque components do not differ qualitatively from coronary plaque ; atherosclerosis plaque of BA may have remodeling exactly as in coronary arteries .
Right internal carotid angiogram showed complete occlusion of the right middle cerebral artery and the formation of moyamoya vessels in the basal ganglia and a persistent primitive trigeminal artery (PPTA) that branched from the C4 portion of the right internal carotid artery and terminated at the upper portion of the basilar
artery [Figure 1]c.
