INTRODUCTION: Benign paroxysmal positional vertigo (BPPV) pathophysiology is based on otoconia migration from the utricle and saccule to the semicircular canals, however, the role of the saccule is still under study. Our aim is to study the otolith damage in these patients with vestibular evoked myogenic potentials (VEMPS) and correlate the results with those of computerised dynamic posturography (CDP). MATERIAL AND METHODS: We present 79 patients diagnosed with BPPV between March and June 2017...

OBJECTIVES: To determine the diagnostic accuracy of ocular vestibular evoked myogenic potentials (oVEMPs) for superior canal dehiscence syndrome (SCDS) in a large cohort of unselected dizzy patients. Most SCDS patients are dizzy (90%); however, only 30% demonstrate archetypical SCDS clinical proxies (Tullio or Hennebert findings). Several case-control studies have addressed specific SCDS markers using VEMP testing, but the diagnostic value of VEMP for SCDS has not been demonstrated in a target population of dizzy patients...

Air-conducted sound and bone-conduced vibration activate otolithic receptors and afferent neurons in both the utricular and saccular maculae, and trigger small electromyographic (EMG) responses [called vestibular-evoked myogenic potentials (VEMPs)] in various muscle groups throughout the body. The use of these VEMPs for clinical assessment of human otolithic function is built on the following logical steps: (1) that high-frequency sound and vibration at clinically effective stimulus levels activate otolithic receptors and afferents, rather than semicircular canal afferents, (2) that there is differential anatomical projection of otolith afferents to eye muscles and neck muscles, and (3) that isolated stimulation of the utricular macula induces short latency responses in eye muscles, and that isolated stimulation of the saccular macula induces short latency responses in neck motoneurons...

OBJECTIVES: Pediatric vestibular evaluations incorporate cervical and ocular vestibular evoked myogenic potential (c- and oVEMP, respectively) testing; however, in children, c- and oVEMP thresholds have been minimally investigated and frequency tuning is unknown. Children are also at risk for unsafe sound exposure secondary to VEMP. While it is unknown if VEMP threshold testing leads to cochlear changes, it is possible that this risk increases due to the increased number of trials needed to obtain a threshold...

REVIEW
R Huang, G R Bi
The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait, deficits of spatial memory and navigation. The etiology of BVP remains unclear in more than 50% of patients: in these cases neurodegeneration is assumed. Frequent known causes are ototoxicity mainly due to gentamicin, bilateral Menière's disease, autoimmune diseases, meningitis and bilateral vestibular schwannoma, as well as an association with cerebellar degeneration. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR)...

A 46-year-old female with profound sensorineural hearing loss in her left ear from childhood developed tinnitus and fluctuating hearing loss on the right side 8 years ago. Four years later, paroxysmal episodes of rotatory vertigo occurred with gradually increased frequency, lasting from half an hour to 2 hours and accompanied with nausea and vomiting. Audiometric test revealed severe sensorineural hearing loss in both of her ears. The tympanograms showed type A on both sides. The threshold of auditory brainstem response was 97 dBnHL in her right ear while no waves could be educed on her left side...

OBJECTIVE: Cervical vestibular-evoked myogenic potentials (cVEMPs) are short-latency vestibulocollic reflexes. The damage on any point of the vestibulocollic reflex pathway could affect the cVEMPs. Whether neck dissection has an effect on the sacculocollic pathway, and consequently on cVEMPs, remains unexplored. The aim of this study was to evaluate the cVEMP findings in patients with functional neck dissection without vestibular symptoms. PATIENTS AND METHODS: This cross-sectional study design, 20 patients who had undergone unilateral neck dissection with sparing of the accessory nerve, SCM and internal jugular vein, were included...

Background: Rhinoplasty is a common surgical procedure that is requested and accepted by patients for cosmetic and functional reasons. Osteotomies are performed on nasal bone, maxillary crest, or vomer to fix the deviations of the nasal dorsum or septum. During the percussion of the osteotomes with the surgical mallet, the vibration energy diffuses to the cranium. Auditory and vestibular systems may be affected by these vibrations. Objectives: To assess the effects of rhinoplasty, in which osteotomies were performed using a hammer, on the audiovestibular system...

Superior canal semicircular dehiscence (SCCD) may cause vestibular and audiological symptoms that are sometimes debilitating. Computed tomography (CT) and the vestibular evoked myogenic potential (VEMP) test are essential for the diagnosis of SCCD. Various surgical techniques have been developed to manage SCCD but have many associated complications. Our technique uses an approach that otologists and surgeons are highly familiar with and that has other advantages, such as minimizing surgical trauma and preventing recurrences...
