Vertigo and dizziness of functional origin

In patients consulting otologists for vertigo a functional source can be expected in 50% of the patients and more frequently among young females than among older male subjects. Functional vertigo is frequently perceived as a turning sensation inside the head, functional dizziness frequently as a rocking sensation of the whole body, while patients with vertigo of somatic origin frequently seem to complain of a spinning sensation outside the head. The duration pattern of functional vertigo is frequently of a fluctuating or continuous type, while in the nonfunctional subjects it is of 2-5 hr. duration. In patients with vertigo of functional origin eye-closure tends to release rather than inhibit nystagmus.     

Vertigo/dizziness following COVID-19 vaccination

PurposeThis study assessed the vertigo/dizziness in patients following COVID-19 vaccination.Patients and methodsFrom July 2021 to June 2022, totaling 50 patients with dizzy spells following COVID-19 vaccination by AZ (AstraZeneca-Oxford University, AZD1222), BNT (Pfizer-BioNTech, BNT162b2) or Moderna (Moderna, mRNA-1273) vaccine were enrolled in this study. The interval from vaccination to the onset of vertigo/dizziness was compared with inter-episodic interval of vertigo/dizziness in the same patients, but without vaccination, during past one year (2020).ResultsThe incidences of severe systemic complication per 10⁶ shots were 0.86 for Moderna vaccine, 1.22 for AZ vaccine, and 1.23 for BNT vaccine. Conversely, rate of post-vaccination vertigo/dizziness was noted in the Moderna group (66 %), followed by the AZ group (20 %) and the BNT (14 %) group, meaning that type of COVID-19 vaccine may affect various organ systems. The median time to the onset of vertigo/dizziness following vaccination is 10d, which is consistent with the onset of IgG production, and significantly less than inter-episodic interval (84d) in the same patients without vaccination.ConclusionPost-vaccination vertigo/dizziness can manifest as exacerbation of previous neurotological disorder. The median time to the onset of vertigo/dizziness following COVID-19 vaccination is 10d. Since the outcome is fair after supportive treatment, the immunomodulatory effect of the vaccines does not undermine the necessity of the COVID-19 vaccination.     

Effects of greater occipital nerve block on tinnitus and dizziness

We analyzed relationships among tinnitus relief, dizziness, and results of vertical autocorrelation studies of head movement to investigate the effect of greater occipital nerve block on the sensory and motor system in 2 patients with abnormal head movement. Tinnitus improved in 14 (52%) of 28 tinnitus patients after occipital nerve block. The percentage of patients reporting tinnitus improvement (54%, or 7 patients) among 13 patients without a history of trauma was not significantly higher than among 12 patients with trauma (33% or 4 patients). However, tinnitus improvement in patients with dizziness but without trauma was more frequent than that reported by nontraumatic tinnitus patients without dizziness (p<.05). Vertical autocorrelation results while stepping in place were better in patients with tinnitus relief than in those not reporting tinnitus relief (p =.001). Dizziness improved in 8 of 13 patients (62%) with trauma, similar to improvement in 8 of 14 patients without trauma (57%). Improved word perception test results in the presence of noise suggested that improvement in tinnitus and dizziness after occipital nerve block was related to improved attention.     

Psychiatric diagnoses in patients with psychogenic dizziness or severe tinnitus

Psychiatric assessments were made of patients with psychogenic dizziness (N = 17) and severe tinnitus (N = 24) using the Structured Clinical Interview for DSM-III-R (SCID). The psychogenic dizziness group had a high prevalence of psychiatric disorders (100%), the majority being anxiety disorders (94%), particularly diagnoses in the panic-agoraphobic cluster (76%). The severe tinnitus group had a lower prevalence of psychiatric disorders (63%) with a predominance of mood disorders (46%). Those tinnitus patients with no hearing loss tended to have more diagnoses per patient and more anxiety disorders than those with hearing loss. Although this was not a random sampling of these patients populations, the results are of sufficient magnitude to warrant further studies. The implications of the results are discussed in terms of treatment and future research.     

Malignant rhino- and otobasal mucosal melanomas--therapy and outcome

BACKGROUND: Malignant melanoma of the rhinobasal mucosa is very rare and makes up less than one percent of all malignant melanomas. Symptoms are unspecific in most cases, and patients often present with large tumours. During the past two decades, a variety of therapeutic modalities has been proposed. MATERIALS AND METHODS: In a retrospective quality assessment, we analysed the charts of fifteen consecutive patients suffering from malignant melanoma of the skull base who where treated in our department since 1993. The influence of specific surgical and adjuvant therapy on recurrence and outcome was evaluated. RESULTS: Initial symptoms were unspecific in all patients. Thus, melanoma was an accidental finding of a biopsy or sinus surgery in most patients, including all cases with amelanotic melanoma. All patients underwent surgery as the initial treatment, in 8 cases followed by adjuvant therapy. In these patients the disease specific survival was slightly better than in patients treated with surgery only. When recurrence was treated by radical mutilating surgery, this did not influence the overall prognosis. CONCLUSION: We conclude from our data and analysis of literature that the prognosis of MM has not developed favourably during the past two decades. Radiation therapy and adjuvant immuno- or chemotherapy seems to have a positive impact. Mutilating surgery is usually not indicated nor is it associated with an improvement of outcome.     

Cervical tinnitus after cervical vertebrae treatment

There is a wide variety in the discussions on cervical tinnitus as a possibility of hearing disorders. Hearing loss at low frequencies and low frequent tinnitus are typical signs in this context. It is important to remember that these complaints occur not only with pathological changes in the cervical spine, but possibly also after treatment in this region. The patients presented here suffered from tinnitus or hearing loss after treatment of the cervical region. In all cases the cervical spine is clearly indicated as having triggered the signs. When diagnosing and treating patients with complaints of the cervical area, there should be close cooperation between the physician, the patient and the physiotherapist.     

Different forms of dizziness occurring after cochlear implant

Dizziness after cochlear implant (CI) was studied in a series of 94 consecutive adult patients receiving a cochlear implant, 46 (49.0%) of whom experienced dizziness post-operatively. In 29 patients, post-operative dizziness occurred soon after surgery and subsided within one month. Dizziness of the continuous type, lasting more than 6 months, was a complaint in only two patients. In addition to these already known forms of dizziness, spells of vertigo occurring later than one month after cochlear implant were experienced by 15 patients (delayed-V). The spells of delayed-V occurred suddenly and persisted for several hours. Moreover, 85.7% of delayed-V patients complained of hearing and tinnitus abnormalities during these spells. The clinical features of delayed-V were similar to those in patients with Ménière’s disease. The preoperative bithermal caloric test showed a significantly higher response for the delayed-V group than the other groups (ANOVA: P < 0.05) in terms of slow phase eye velocity of caloric nystagmus. These findings suggest that inner ear lesions due to cochlear implant surgery develop gradually. Similarities in clinical features between delayed-V and Ménière’s disease indicate the presence of labyrinthine hydrops. Received: 28 March 2000 / Accepted: 12 October 2000     

Vertigo, imbalance and mourning

It is a well-known fact, and there are several publications on this matter, the links between panic attacks, simulation, anxiety, depression and lightheadedness or imbalance, but in our perusal of the related literature no connection between pathological mourning, dizziness and imbalance was found. In this paper are reported the outcomes of a prospective study of 58 patients suffering vertigo and imbalance as well and psychiatrically assessed. Pathologic mourning shows its predominance among otic vertiginous. This feature, we think, should be investigated when collecting the anamnesis of patients complaining of dizziness and/or imbalance in order to planning the appropriate treatment.     

Nutrition, biochemistry, and tinnitus

Biochemical mechanisms are a significant factor in neurootological problems. Investigation of biochemical causes of neurootological problems, such as tinnitus, are warranted and can be cost-effective. Dietary, nutritional, chemical, hormonal, immunological, and stress factors are involved directly in neurootological problems and must be evaluated and considered in designing the treatment regimen for patients complaining of tinnitus.     

Antidepressants and dizziness

OBJECTIVE: To assess the clinical therapeutic significance of sleep disruption and admitted depression in patients with nonspecific dizziness. DESIGN: Retrospective database review. SETTING: Large tertiary care clinical practice. METHOD: Answers to questions about sleep disruption and depression from 137 patients who met inclusion criteria for nonspecific dizziness and a comparison group of 39 patients were contrasted. The Pearson chi-square test was used to determine the statistical significance of the results. MAIN OUTCOME MEASURE: Six weeks after beginning antidepressant therapy, patients were asked if their symptoms improved significantly. RESULTS: Patients with nonspecific dizziness reported more sleep disruption and admitted to depression more frequently than the comparison group. Persons with sleep disruption were more likely to respond to antidepressant therapy than those without sleep disruption. CONCLUSIONS: (1) Sleep disruption is common in persons with nonspecific dizziness. (2) Nonspecific dizziness may respond to antidepressant therapy, particularly in patients who report sleep disruption and/or depression.     

Otoacoustic emissions and persistent tinnitus after acute acoustic trauma

OBJECTIVES: To follow up the auditory status of military personnel after an acute acoustic trauma and to identify the possible predictive value of hearing thresholds and otoacoustic emissions during the first 24 hours after the acoustic trauma. STUDY DESIGN: A group of 24 young military subjects, aged 22 +/- 2.3 years, without any otologic problem before the acoustic trauma, were examined at three time intervals after an accidental acoustic trauma caused by the discharge of a firearm: 24 hours, 72 hours, and 15 days. METHODS: Each subject was submitted to medical examination and to a questionnaire detailing the circumstances of the acoustic trauma. Pure tone audiometry was performed from 1 to 8 kHz per half octave. Transiently evoked otoacoustic emissions were recorded in the nonlinear mode at 80 dB pSPL, and distortion product otoacoustic emissions were recorded from 1 to 6 kHz, using a distortion product-gram type procedure, at 65/55 dB SPL, with f2/f1 = 1.22. Two groups of subjects were defined: group 1 (n = 8) represented subjects with short-lasting tinnitus (<72 h) and group 2 (n = 16) subjects with long-lasting tinnitus (>72 h). RESULTS: Hearing thresholds did not differ significantly between these two groups 24 hours after the acoustic trauma. However, otoacoustic emissions showed significantly lower amplitudes 24 hours after the acoustic trauma in subjects showing a longer lasting tinnitus. CONCLUSION: Otoacoustic emissions appear to be a better predictor of the persistence of tinnitus than hearing thresholds alone 24 hours after an acute acoustic trauma.     

Vertigo after head injury--a five year follow-up.

Three hundred and twenty-one head injury patients investigated at the Workmen's Compensation Board Hospital and Rehabilitation Centre were studied. The patients were classified into two groups, minor and moderate according to the duration of post-traumatic amnesia. Post-traumatic vertigo was a significant symptom in 34 per cent and 50 per cent of the minor and moderate groups respectively. Based on the findings of full otoneurologic and vestibular examination, objective vestibular disorder was noted in 40 per cent and 65 per cent of the two vertiginous groups respectively. An approach to the interpretation of vestibular and oculomotor abnormalities is outlined in order to assign a peripheral (end organ or nerve), central (brainstem or cerebellar) or undertermined localization. Hearing loss occurred in 20 per cent of the minor and 72 per cent of th e moderate head injury patients tested. A five-year post head injury follow-up was available with respect to recovery of vertigo and work rehabilitation. The results of this follow-up are discussed.     

Pulsatile tinnitus caused by pneumocephalus after Janneta surgery

Pulsatile tinnitus of nonvascular origin is rare. We herein present a case of pulsatile tinnitus complicated with Jannetta surgery due to a communication created between the drilled mastoid cells and epidural space. She was successfully cured by otological surgery where the mastoid tip was packed with bone cement. A 68–year-old woman was referred to the previous hospital with complaints of right autophony, aural fullness, hyperacusis to her footsteps, and pulsatile tinnitus for the past three years. She had received Jannetta surgery for right hemifacial spasm seven years before. The computed tomography (CT) of the right temporal bone showed bony dehiscence between the mastoid cells and posterior cranial fossa. She underwent otological surgery to obliterate the tip of the mastoid cavity with artificial bone cement (BIOPEX^?) under general anesthesia. Her annoying aural symptoms were immediately abolished and she has been free from symptoms at ten months after surgery. It is critical to ensure the closure of any communication created between the middle ear and epidural space during surgeries in order to prevent the occurrence of pulsatile tinnitus.
