Dysgeusia, characterized as an altered perception of taste to any one of the four major tastant qualities (sweet, salt, sour, and bitter), is frequently experienced after dental anesthesia and neuroma (middle ear) surgery. Many medications, ranging from antiinflammatory drugs and protease inhibitors to antihypertensive drugs such as amiloride, have also been found to disrupt gustatory perceptio...

Hereditary motor and sensory neuropathy (HMSN) types I and III and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) in developed countries are the most frequent causes of enlargement of peripheral nerves, “hypertrophic neuropathy”, with clinically palpable thickened nerves, visible on MRI. They may even be the cause of spinal cord compression. 8 We report on a patient who develo...

The upper airway (nasal passages, paranasal sinuses, pharynx, and glottis) provides the sentinel portion of human respiratory tract, with combined senses olfaction (cranial nerve I) trigeminal sensation V) signaling quality inspired air. Trigeminal function also complements sense taste (in turn mediated by cranial nerves VII, IX X), participates in genesis aversions. ability stimulation aero-di...

A 38-year-old man presented with influenza A (H1N1) pneumonia complicated by acute respiratory distress syndrome, resulting in an extended intensive care unit stay (37 days). After he was extubated, he was found to have left-side IX, X and XII cranial nerve palsies. Computed tomography of his neck showed bilateral elongated styloid processes (5.0 cm long; Figure), consistent with Eagle syndrome...

A total of 311 patients with a unilateral acoustic neurinoma were operated on via the enlarged middle cranial fossa approach. A total tumor removal was achieved in 98% of cases. The mortality was 0.6%. Overall in acoustic neurinoma surgery, the percentage rates of meningitis (1.6%), cerebrospinal fluid fistula (1.6% requiring surgery), and neurological deficits were fairly low. The facial nerve...

Cranial nerve lesions often accompany head trauma. Olfactory, facial and vestibular nerves are the most commonly injured nerves. Optic and oculomotor nerve injuries are less frequently involved, and trigeminal, abducens and lower cranial nerves are rarely involved. The injury may occur in central nervous system or in the lower motor unit. Traumatic bilateral abducens paralysis is a very rare oc...
