Furthermore, radiologic investigations help in determining tumor deep infiltration, lymph nodes involvement, and the presence of distant metastases. These should complement clinical evaluation by giving a more precise view of the disease characteristics, its overall behavior, and pattern of spreading.

Cervical- and ocular-VEMPs are short latency surface potentials produced through the activation of saccular and utricular afferents by sound and vibration. They are tests of dynamic otolith function. The SVV/H test in peripheral lesions probes static asymmetries in utricular function and represents a perceptual error in perceived gravitational vertical/horizontal. VEMPs and SVV/H enable the characterization of patterns and severity of otolith dysfunction in common vestibular disorders. Combined with tests of semicircular canal function, they provide a useful tool for eliciting diagnostic profiles in vestibular neuritis and Ménière's disease.

However, recent trends in the developed world show that there has been an annual increase in the percentage of women with hypopharyngeal cancer. In France, there has been a significant annual percentage change in the incidence of this form of cancer - a decrease in men and a greater increase in women since the 1980s. In the developing world, India, Taiwan and other countries, the incidence of hypopharyngeal cancer has increased in both men and women. These populations indulge widely in the social habit of tobacco usage at an earlier age, both smoking and chewing, excessive alcohol drinking, along with the chewing of the areca nut. Recent research has proven that areca nut alone is carcinogenic. The combination of tobacco and alcohol has a greater multiplicative impact on increasing the risk of cancer, while the involvement of areca nut remains to be proven. The World Health Organisation has commenced a Global Mission on the cessation of smoking and reduction of alcohol intake. The effect of this work has been credited with a reduction of hypopharyngeal and other head and neck cancers.

Panic attacks may cause or contribute to acute or episodic vestibular symptoms. Generalized anxiety and depression do the same for chronic vestibular symptoms. Fear of falling causes considerable functional impairment, particularly in the elderly. Persistent postural-perceptual dizziness, a newly defined functional vestibular disorder that was 145 years in the making, is the most common cause of chronic dizziness in neurotologic practice. These 5 disorders are the primary diagnoses in 8-10% of patients who consult neurologists or otologists for vestibular symptoms and may be present in up to 50% of patients with structural vestibular disorders.

The aminoglycoside class of antimicrobials has been especially well studied in this regard. Many questions remain unanswered as to how to best monitor and prevent this complication. A bilateral vestibular loss profoundly affects an individual's quality of life, physical activities, and overall independence. Paradoxically, the effects of gentamicin ototoxicity have provided further insight into the workings of the vestibular system, especially the vestibulo-ocular reflex. The microbiological activity, therapeutic use, toxicities, and genetics predisposing a person to aminoglycoside ototoxicity are presented. The clinical importance of recognizing ataxia, disequilibrium, and oscillopsia as presenting symptoms for vestibulotoxicity rather than hearing loss or vertigo is stressed. Documented risk factors and new observations regarding the spectrum of vestibular dysfunction and differences in vestibulotoxicity from multiple daily dosing vs. single daily dosing schedules are presented for the first time. While most vestibulotoxicity arises from systemic aminoglycoside administration, intratympanic application has been used therapeutically for intractable Ménière's disease.

Recent Findings: Recent evidence supports the canalolithiasis model as the pathophysiological mechanism and predominant subtype of BPPV. Scanning electron micrographs of extracted posterior semicircular canal contents show free-floating otoconia of utricular origin. Calcium homeostasis has also been shown to contribute to the pathogenesis of the disorder by creating an environment in which otoconia are more prone to dislodging from their native gelatinous substrate. Recent findings have served to identify variant-specific provocative tests with the greatest diagnostic utility while simultaneously maximizing their diagnostic yield. Current data have also helped elucidate the efficacy of repositioning maneuvers and surgical interventions.
