The neurootological data of 12 patients attending our ear, nose, and throat clinic were analyzed. The patients submitted to a neurootological routine evaluation consisting of patient history recording and audiometric and equilibriometric investigations (i.e., electronystagmography). The conclusion was that many tinnitus patients--even those who had no vestibular symptoms--showed some disturbanc...

MATERIALS and METHODS: This is a prospective work in 123 patients with different types of vestibular disease seen because of dizziness in which both procedures were performed the same day. First, the spontaneous nystagmus and head-shake nystagmus were measured. The video head-impulse test was carried out, and finally, the caloric test was performed with water at two different temperatures. Both...

To ensure high acuity vision, eye movements have to be controlled with astonishing precision by the oculomotor system. Many human diseases can lead to abnormal eye movements, typically of the involuntary oscillatory eye movements type called nystagmus. Such nystagmus can be congenital (infantile) or acquired later in life. Although the resulting eye movements are well characterized, there is on...

Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo and nystagmus in clinics. Vertigo has many causes and the recurrence of vertigo is unknown. Among a lot of factors, vitamin D deficiency is more important. This study was conducted to determine the effect of vitamin D supplementation on torsional nystagmus in BPPV patients. This study wants to show the d...

Aim of this study was to determine sensitivity and specificity of the mastoid vibration test in patients who had suffered an attack of vestibular neuritis. Results were compared with the caloric test and two bedside tests of vestibular function (head shaking test and head thrust test). Results are reported in 28 patients who had a residual vestibular deficit 6 months after acute neuritis and in...

INTRODUCTION Cochlear implants are undeniably an effective method for the recovery of hearing function in patients with hearing loss. OBJECTIVE To describe the preoperative vestibular assessment protocol in subjects who will be submitted to cochlear implants. METHODS Our institutional protocol provides the vestibular diagnosis through six simple tests: Romberg and Fukuda tests, assessment f...

OBJECTIVE To characterize (1) the impairment and recovery of functional balance and (2) the extent of vestibular dysfunction and physiological compensation following superior canal dehiscence syndrome (SCDS) surgical repair. DESIGN Prospective study. SETTING Tertiary referral center. PARTICIPANTS Thirty patients diagnosed as having SCDS. INTERVENTIONS Surgical plugging and resurfacing o...

The symmetry of primary and secondary optokinetic afternystagmus (OKAN I and OKAN II, respectively) was studied in 14 patients with vestibular neuritis, as well as in 50 normals. The patients were examined at onset of symptoms and at follow-up 3 and 12 months later. At onset, OKAN was found mainly to reflect the spontaneous nystagmus. Although the spontaneous nystagmus disappeared in all patien...

Spontaneous reports of oscillopsia are rare in cases of congenital nystagmus (CN). We examined the relationship between nystagmus waveform characteristics and oscillopsia in one such case. To reduce the patient's nystagmus, she was fitted with contact lenses. We examined the effects of tactile feedback by applying local anesthetic while she wore the lenses. When she was without lenses, we provi...
