The association between positional vertebral and basilar artery flow lesion and prevalence of vertigo in patients with cervical spondylosis.

OBJECTIVE: The aim of our investigations was to characterize the relationship between basilar artery (BA) flow velocity in patients with cervical spondylosis and age, grade of radiological changes, prevalence of vertigo, and decreased blood flow velocity through vertebral arteries (VA) after head rotation. STUDY DESIGN AND SETTING: A prospective, controlled study in academic neurotology was conducted. We examined 80 patients with radiological evidence of cervical spondylosis. Forty patients complained of positional vertigo lasting more than 6 months. Patients were examined by transcranial Doppler ultrasound with head rotations. RESULTS: We showed significant association between velocity flow in basilar artery after neck rotation and age, prevalence of vertigo, grade of radiological changes, and positional vertebral artery flow lesion. CONCLUSION: Spondylotic-induced VA compression may be the reason for decreased blood flow velocity in the basilar artery during head rotation, which may be of particular importance for older patients, especially complaining of vertigo. SIGNIFICANCE: Every patient with high-grade cervical spondylosis, especially complaining of vertigo, should be examined by using TCD (transcranial Doppler) with head rotations. In case of positional blood flow reduction during head rotation, further angiographic examination should be undertaken so as to plan suitable treatment. EBM RATING: C-4.

[Hearing evaluation in patients with vertigo].

INTRODUCTION: Vertigo is one of the most frequent and disturbing sensations that the practicing otolaryngologist is called upon to treat. Vertigo is the illusory sensation of motion. True vertigo is caused by pathology in the peripheral end organ, the vestibular nerve, and the pathways that connect them in the brainstem and rarely, in the cortex. AIM: The aim of this study was to evaluate hearing in people with vertigo according to the etiology of balance disorders. The study comprised 127 patients treated in our clinic between 1999 and 2004, 88 women and 39 men (254 ears) aged 24-90 years. The average age was 56. METHODS: Hearing tests (pure tone audiometry, speech audiometry, impedance audiometry, auditory brainstem responses, OAE) as well as vestibular function tests (electronystagmography, rotational chair tests, caloric tests) were performed. In order to evaluate the nature of vertigo radiological diagnostics (head and cervical computer tomography, vascular diagnostics using Doppler sonography) was performed. RESULTS: Audiometric testing showed impaired hearing in 71 of 127 subjects. Among 73 patients with vertigo of vascular origin caused by vertebrae-basilar insufficiency, bilateral cochlear lesion was noticed in 33 cases and unilateral in 9. In 8 patients with cervical ankylosing spondylitis 3 had cochlear hearing loss (1--unilateral, 2--bilateral). CONCLUSIONS: In our group of patients with vertigo in the most of cases the hearing loss was on cochlear origin.

[Distortion product otoacoustic emissions before and after one year exposure to impulse noise].

INTRODUCTION: Firearms are a common source of impulse noise that may be very harmful to the auditory organ. Impulse noise from weapons and explosions continually produces hearing damage among military personnel. The discovery of otoacoustic emission (OAE) has given a new possibility of early diagnosis of noise induced hearing loss. The transiently evoked otoacoustic emission (TEOAE) and distortion product otoacoustic emission (DPOAE) are non-invasive, objective and frequency specific audiometric tests for evaluating outer hair cell function. The aim of the study was to asses the effects of exposure to impulse noise on DPOAE after one year of the obligatory military service. MATERIAL AND METHODS: The study comprised 92 (184 ears) soldiers, subjected to impulse noise during military service. The examine group was divided according total noise exposure. The control group consisted of secondary school students not exposed to noise. DPOAE was recorded before and after one year of military service. RESULTS: After military service significant deterioration of DPOAE level was observed at frequencies of 1, 3, and 4 kHz on the right ear and 2, 5 and 6 kHz left one. CONCLUSIONS: 1. Reduction of DPOAE amplitude connected all frequencies. 2. We did not notice significant differences between groups connected total noise exposure.

[Impulse noise influence on hearing].

UNLABELLED: Impulse noise from weapons and explosions produces hearing damage among military service. The discovery of otoacoustic emissions (OAE) has given a new possibility of early diagnosis of noise induced hearing loss. The aim of the study was to assess the effects of exposure to impulse noise on TEOAE, SNR and PTA. MATERIAL AND METHODS: the study comprised 92 (184 ears, aged 18.5-20 years) soldiers, subjected to impulse noise during one year of military service. The soldiers were divided in to three groups according exposure to noise. Group I the highest exposure 2222, 9 kPa2/s, group II--611, 8 kPa2/s and group III--103-109 kPa2/s. The control group consisted of 60 (120 ears) secondary school students. Hearing evaluation was performed before and after one year of military service, using extended pure tone audiometry, tympanometry, TEOAE and SNR. RESULTS: after military service significant deterioration of hearing was observed on average 1-2 dB for 0.125-3 kHz and 4-6 dB for 4-12 kHz for all examined soldiers without differences between groups. TEOAE reductions were registered predominantly at frequencies of 3 and 4 kHz, for both ears and SNR mean values reduction for the frequencies of 2, 3 and 4 kHz. CONCLUSIONS: TEOAE especially in cases where clinical audiometry is less sensitive can monitor small changes in the cochlea. There were no differences between groups and ears.

[Analysis of select diagnostic examination results and their connection with cervical vertigo diagnosis].

Cervical spine spondylotic changes are known to cause vertigo, but diagnostic criteria are not established. The aim of present study was to asses diagnostic value of classical radiologic, electronystagmographic (ENG) and transcranial doppler ultrasonographic (TCD) examinations in cervical vertigo diagnostic process. Forty patients with vertigo lasting more than 6 months with radiological evidence of cervical spondylosis participated in the study. All patients had ENG and TCD with neck rotation test. Cervical vertigo was diagnosed in patients with positive neck rotation test in: TCD examination (15% decrease of vertebral artery flow) and/or ENG examination (cervical nystagmus). We diagnosed cervical vertigo in 65% of patients. Multivariate model of logistic regression analysis showed that the best statistical predictors of cervical vertigo were: asymmetry of vertebral artery flow in TCD (OR: 92.2; 95% CI: 6,2-1381) and presence of osteophytes and discopathy in radiological examination (OR: 64.1; 95% CI: 1,3-1107). The transcranial doppler ultrasonographic examinations seems to be useful for diagnosing cervical vertigo.

[Kinesitherapy treatment for patients with cervical vertigo (preliminary report)].

The aim of the study was to assess the effectiveness of kinesitherapy in cervical vertigo treatment. Thirty two patients with cervical vertigo, aged 20 to 75, were examined. The patients performed kinesitherapy exercises three times a day for four weeks. The effects of therapy were assessed by everyday task self-control cards and ENG examinations. In the present study, objective improvement was noticed in 18,7% patients. Subjective improvement assessed by the patients everyday task self-control cards reached 62.5%. Kinesitherapy seems to be the good method of treating neck-related vertigo, but it should be confirmed in further study on the large group of patients.

[Phlegmon neck and face as a complication peritonsillar abscess--case report].

The authors describe a 46-year-old male patient. Inflammatory state of tonsils and peritonsillar abscess caused a serious complication which came to parapharyngeal phlegmon and superficial soft tissue phlegmon face and neck. A wide application of antibiotic gives a rare complication, but mortality reaches a few percent. A basic method is a surgical treatment--a wide cut of tissues in many places, to drainage interfascia space and compound aim intravenous antibiotic therapy.

[Middle ear schwannoma--case report].

Schwannoma is one of the common benign middle ear space tumors. The tumors may present with facial nerve paresis or palsy, otologic symptoms and/or parotid mass middle ear schwannomas may originate from the nerves of the tympanic caviti or by extensions from outside the middle ear space. Schwannomas of the facial nerve can occur along any segment, but they frequently involve the geniculate ganglion and extend proximally or distally from there. MRI and CT imaging characteristics are similar to those of vestibular schwannomas. We present the clinical and radiologic features of a middle-space schwannoma originating from facial nerve. The patient underwent middle ear exploration and mastoidectomy. The tumor was of facial nerve origin and was separated from middle ear. The pathologic diagnosis was schwannoma.

Evaluation of Transient and Distortion Product Otoacoustic Emissions before and after shooting practice.

Firearms are a common source of impulse noise that may potentially damage a hearing organ. It is not easy to predict soldiers' personal susceptibility to noise exposure. The purpose of this study was to evaluate of the transient evoked otoacoustic emission (TEOAE) and distortion-product otoacoustic emission (DPOAE) before and after shooting and compare it with conventional pure tone audiometry. Standard pure tone audiometry, tympanometry, TEOAE and DPOAE measurements were recorded before and 10-15 minutes after shooting. Ten male soldiers (20 ears) were exposed to impulse noise from automatic gunfire (15 single rounds of live ammunition). They did not use any earplugs. The reduction in amplitude of the TEOAE after shooting was 3.1 and 5.1 as SPL for 3 and 4 kHz respectively for the right ear and 4.3 dB SPL for 1 kHz and 0.6 dB SPL at 2 kHz for the left ear. The greatest reduction in DPOAE occurred at frequencies of 1.0 kHz (3.8dB SPL) and 3.0 kHz (2.9 dB SPL) for the left ear. There were no differences in the audiometric thresholds before and after shooting. Emissions appear to be more sensitive for monitoring early cochlear changes after shooting, than pure tone audiometry.
