MR imaging was used to evaluate the relationship of the root exit zone of the seventh cranial nerve to surrounding vascular structures in 13 patients with clinically documented hemifacial spasm and in 70 asymptomatic patients. MR imaging clearly demonstrated the course of the seventh nerve from the root exit zone of the brainstem to the internal auditory canal and its relationship to the surrou...

BACKGROUND Heritable disorders of connective tissue are recognized in a small minority of patients with neurovascular diseases. In this report, we review the neurovascular manifestations of four heritable connective tissue disorders: Ehlers-Danlos syndrome, Marfan's syndrome, osteogenesis imperfecta, and pseudoxanthoma elasticum, as well as two other systemic disorders with potential vascular m...

U pper extremity fractures are often evaluated by primary care physicians at the patient’s initial presentation or at followup after the emergency department. These fractures account for approximately 2 million emergency department visits annually. Eighteen percent of the visits are for humeral fractures; 31 percent are for radial or ulnar fractures; and 51 percent are for carpal, metacarpal, o...

Pain during extraction of impacted mandibular third molars which can occur despite adequate local anesthesia is termed as “escape pain phenomenon”. Recently, it was described during elevation of a mesioangular impacted mandibular third molar and also while curetting an extracted third molar socket. This phenomenon has been overlooked, as it was previously considered secondary to pressure effect...

The posterior circulation is part of the brain circulation that is subject to stroke. Strokes which involve the posterior circulation account for approximately 25% of all ischemic strokes, and about 10-20% of all hemorrhagic strokes. While the mortality rate from ischemic strokes in posterior circulation could be as low as 4%, the cerebellar and pontine hemorrhages carry a mortality rate close ...

Neurovascular contact is considered a frequent cause of classical trigeminal neuralgia and microvascular decompression with transposition of a blood vessel is preferred over other surgical options in medically refractory patients with classical trigeminal neuralgia. However, the prevalence of neurovascular contact has not been investigated in a representative cohort of patients with classical t...
