Opis:
Aim: The aim of the study was to assess the acoustic and capacity analysis of singing voice using DiagnoScope Specialist software. Material and methods: The study was conducted in 131 adult subjects, including 74 women and 46 men aged 21–51, divided into 3 groups: I – 40 subjects (treatment group) – professional vocalists, II – 40 subjects (treatment group) – semiprofessional vocalists, III – 40 subjects (control group) – students of The Military Medical Faculty at the Medical University of Lodz – nonsingers. The research methodology included: primary medical history, physical examination (otolaryngological), videolaryngoscopic examination, the GRBAS scale for subjective voice evaluation, diagnostic voice acoustic and capacity analysis using DiagnoScope Specialist software, survey on lifestyle patterns which may affect voice quality. R esults: Average value of the fundamental frequency F0 was the highest in professional vocalists group; it was 316.46 Hz in women and 165.09 Hz in men. In semiprofessional vocalists group it was accordingly 260.50 Hz and 149.26 Hz, in nonsingers group it was accordingly 261.23 Hz and 159.27 Hz. The mean value of Jitter parameter in professional vocalists group was 0.30% in women and 0.54% in men, in semiprofessional vocalists group it was accordingly 0.31% and 0.57%, in nonsingers group it was 0.31% and 0.56%. The mean value of Shimmer parameter in professional vocalists group was 3.27% in women and 3.75% in men, in semiprofessional vocalists group it was accordingly 3.46% and 3.77%, in nonsingers group it was 4.33% and 4.39%. The mean value of the NHR index in professional vocalists group was 3.28% in women and 6.00% in men, in semiprofessional vocalists group it was accordingly 3.23% and 6.72%, in nonsingers group it was 3.89% and 6.13%. Conclusions: Values of the parameters which measure the character of the voice, relative period-to-period fundamental frequency perturbations, relative period-to-period amplitude perturbation and level of buzzing together with other methods have diagnostic and predictive value in early detection of voice disorders. Capacity analysis in singing voice showed very low values of the following parameters: phonation time, true phonation time, no phonation coefficient, voice efficiency coefficient and voice capacity.

Opis:
Introduction. The aim of this work was to describe acoustic neuromas as the first signs of inner ear functional disorders. Material and methods. The study covered 3,456 audiological and otoneurological patients, who were treated in the Department of Otolaryngology, Laryngological Oncology, Audiology and Phoniatrics Military Medical Academy University Teaching Hospital in Lodz within the period of 2011–2016. Among the studied subjects, an acoustic neuroma on the vestibulocochlear nerve was diagnosed in 13 cases (5,16%), including 9 women and 4 men. Each patient underwent a medical interview and an objective examination with static and dynamic tests, pure tone audiometry and speech audiometry tests, impedance audiometry tests, characteristics of tinnitus, videonystagmography and auditory brainstem evoked potentials (ABR) in crack. In each case of an incorrect ABR recording, contrast-enhanced MRI was performed. Study results. The conducted tests showed an incorrect ABR recording in 252 patients (7,29%, including 54,37% women and 45,63% men). In the performed contrast-enhanced MRI, 13 patients (5,16%), including 3,57% women and 1,59% men, had an image typical to neuroma of the vestibulocochlear nerve. Each one of the studied patients showed signs and symptoms typical to an acoustic neuroma such as hypoacusia and balance disorders, tinnitus in 12 subjects, headaches in the temporal and occipital area in 4 subjects, trigeminal neuralgia symptoms in 2 subjects and vision problems like scotoma and blurred vision reported by 1 patient. Conclusion. Each case of sensorineural hearing loss, particularly unilateral sensorineural hearing loss, requires expanded hearing tests and auditory brainstem evoked potentials tests. An incorrect brainstem evoked potentials recording such as: an elongated latency of the 5th wave, an elongated interlatency of 1–2-3 and 1–2–3–4 waves, requires a contract-enhanced magnetic resonance imaging to diagnose cerebellopontine angle tumours.

Opis:
Introduction: Nystagmus test is the most important and objective method of assessing balance disorders. The caloric test, as the sole test illustrates the excitability of individual labyrinths, enabling the assessment of each of them separately. The aim of the study is a comparative analysis of results of caloric nystagmus test obtained using the method of ENG and VNG in healthy subjects. Material and methods: The study included a group of 20 healthy people, including 10 women and 10 men aged 22-26 years. In all patients were performed medical interview and subject otoneurologic examination. Subsequently, among all subjects the ENG and after 7 days the VNG were performed tests with calibration, evaluation of spontaneous nystagmus and attempts by Hallpike caloric test. The caloric test was conducted by means of HOMOTH air calorimeter in the air temperatures of 30°C and 44°C, and the exposure of the ear lasting 40 sec. Results: In the caloric tests there were no canal paresis that goes beyond the boundaries of accepted norms in any of examined persons. It was observed that averages of slow phases velocities (SPV) were lower in ENG than VNG. The VNG also allow to designate value of absolute directional preponderance of nystagmus and labyrinths excitability. Conclusions: The obtained results show that the VNG test for ENG test is more precise and allows to better describe Hallpike caloric test. The value of Hallpike’s caloric test was significantly increased by the analysis of absolute directional preponderance in VNG.
Wprowadzenie: Najważniejszą obiektywną metodą oceny zaburzeń układu równowagi jest badanie oczopląsu. Badanie kaloryczne jako jedyny test obrazuje pobudliwość poszczególnych błędników, umożliwiając ocenę każdego z nich osobno. Cel pracy: Celem pracy jest analiza porównawcza wyników badania oczopląsu kalorycznego uzyskanych przy użyciu metody ENG i VNG u osób zdrowych. Materiał i metody: Badaniami objęto grupę 20 osób zdrowych, w tym 10 kobiet i 10 mężczyzn w wieku 22-26 lat. U wszystkich chorych przeprowadzono badanie podmiotowe oraz badanie przedmiotowe otoneurologiczne, badanie ENG i w odstępie 7-dniowym badanie VNG z kalibracją, oceną oczopląsu samoistnego oraz próbami kalorycznymi wg Hallpike’a. Test kaloryczny wykonano kalorymetrem powietrznym firmy HOMOTH, używając temperatury powietrza 30°C oraz 44°C, podawanych przez 40 s do ucha. Wyniki: W teście kalorycznym u żadnej osoby nie stwierdzono deficytu kanałowego wykraczającego poza granice przyjętych norm. Zaobserwowano niższe wartości średnie maksymalnej prędkości wolnej fazy oczopląsów w badaniu ENG niż VNG. Ponadto badanie VNG dodatkowo umożliwiło wyznaczenie wartości przewagi kierunkowej bezwzględnej oraz średniej pobudliwości błędników. Wnioski: Uzyskane wyniki wskazują, iż badanie VNG w stosunku do badania ENG jest bardziej precyzyjne i umożliwia dokładniejsze opisanie próby kalorycznej wg Hallpike’a. W badaniu VNG analiza parametru przewagi kierunkowej bezwzględnej znacznie podnosi wartość próby kalorycznej wg Hallpike’a.

Opis:
Introduction: This study aimed to perform comparative analysis of the diagnostic value of the Video Head Impulse Testing (VHIT) Ulmer I and Dix-Hallpike Test in patients with balance system disorders in outpatient healthcare practice and medical jurisdiction. Material and methods: The study included 63 patients, aged 20–79, 28 women (20–72 years) and 35 men (23–79 years),
divided into two groups: group I (study group) – 33 patients with vertigo of mixed origin (on the basis of the Fitzgerald-Hallpike caloric test during the VNG), and group II (reference group) – 30 healthy subjects. After the ENT interview and physical examination, exclusion of pathological lesions in the external acoustic meatus and middle ear, each patient underwent the Fitzgerald-Hallpike caloric test in VNG as well as the VHIT and Dix-Hallpike test, with the evaluation of eyeball reaction during head rotation. Results: In the group of patients with mixed origin vertigo (group I), the Fitzgerald-Hallpike caloric test showed unilateral labyrinth disturbances in 90.9% of the patients (mean 41.8%) and relative directional preponderance of the mean value of 19.0%, whereas in 9.1% of the patients, the detected values of labyrinth excitability were normal. Benign paroxysmal positional vertigo was diagnosed in 9.1% of all the examined vertigo cases. This diagnosis was based on the positive response to the Dix-Hallpike maneuver and indicative of damage to the posterior semicircular canal in VHIT (without signs of deficiency in VNG). Conclusion: VHIT and the Dix-Hallpike test enable quick and precise detection of benign paroxysmal positional vertigo in outpatient healthcare practice and medical jurisdiction.

Opis:
Introduction: The aim of the work was to evaluate one-time recording of ENG and VNG in healthy subjects selected for the given diagnostic tests with reference to the sensitivity and usefulness of this kind of testing in vertigo diagnostics. Material and methods: The tests covered 50 healthy subjects, including 24 women and 26 men aged 20-22 (the mean age of 20,5 years) who did not report any inconvenience from otorhinolaryngological organs and the conducted interview did not reveal any balance disorder or vertigo. Every patient underwent otoneurological subjective and objective tests, electronystagmography (ENG), including a calibration test, head-tracking test, optokinetic nystagmus test, rotatory chair test, positional tests according to Cawthorne and Rose, a Hallpike caloric test as well as videonystagmography which included a calibration test, spontaneous nystagmus evaluation, head-tracking test, positional tests according to Cawthorne and Rose with a head rotation test and Hallpike caloric test. The above tests were performed separately, 24 hours one by one. One-time recording of ENG and VNG was made 48 hours following the last test while each of the two tests was preceded by an additional calibration test. The final recording included the spontaneous nystagmus evaluation, positional tests according to Cawthrone and Rose together with the head rotation test and Hallpike caloric test. Results: Any negative mutual influence of the conducted tests has not been observed. Both in the one-time and separate recording, the caloric test revealed lower values of the mean velocity of the nystagmus free phase in ENG with relation to VNG. No signs from spontaneous nystagmus, as well as optokinetic and positional nystagmus, could be found in any case. Conclusions: The conducted tests did not show any possibility of mutual exclusion of the given ENG and VNG diagnostic tests one-time recording. However, their use in diagnostics of balance disorders and vertigo requires further studies

Introduction. The aim of this study was to analyse the occurrence of inverted papillomas of the nose and paranasal sinuses in patients that underwent endoscopic sinus surgery in our department. Material and methods. Between 2006 and 2016, 3,574 patients underwent surgery due to paranasal sinus diseases. Patients were qualified for surgery based on medical history, computed tomography, and laboratory tests. Data were gathered from medical files, and they included age, sex, and histopathological diagnosis. Results. Among 3,574 patients that underwent surgery due to chronic inflammatory changes, on histopathology, inverted papillomas were diagnosed in 80 patients, including 31 women (38.75%) and 49 men (61.25%). Most patients were aged 60-70 years (women, 12.5%; men, 15%) or 50-60 years (women, 5%; men, 21.25%). Between 2006 and 2016, the number of surgeries ranged from 264 (7.38%) in 2013 to 355 (9.93%) in 2016, and the number of inverted papillomas ranged from 4 in 2007 and 2015 (1.23%) to 12 in 2014 (3.87%). Over the last 4 years of the study period, the incidence of inverted papillomas increased. Conclusions. Among 3,574 patients operated on due to chronic inflammatory changes, on histopathology, inverted papillomas were diagnosed in 80 cases (2.23%); thus, all patients qualified for endoscopic surgery due to inflammatory or hypertrophic changes should undergo rhino-fiberoscopy. Recurrence of inverted papillomas was observed in 17.50%, typically in patients with nasal polyps that co-occurred with inverted papillomas. We regard rhino-fiberoscopy as the most valuable method for detecting tumour recurrence in patients after surgery for inverted papillomas ranged from 4 in 2007 and 2015 (1.23%) to 12 in 2014 (3.87%). Over the last 4 years of the study period, the incidence of inverted papillomas increased. Conclusions. Among 3,574 patients operated on due to chronic inflammatory changes, on histopathology, inverted papillomas were diagnosed in 80 cases (2.23%); thus, all patients qualified for endoscopic surgery due to inflammatory or hypertrophic changes should undergo rhino-fiberoscopy. Recurrence of inverted papillomas was observed in 17.50%, typically in patients with nasal polyps that co-occurred with inverted papillomas.

Introduction. The aim of the study was to evaluate the neck torsion test in objective examinations of patients with vertigo and/or hearing loss. Material and methods. The study was conducted in 100 patients, including 54 women and 46 men aged 17–79 years, who were divided into two groups: I – 50 patients, including 30 women and 20 men aged 17–79 years (mean age 49.92 years) with dizziness and/or hearing impairments, and confirmed asymmetry of intracranial vessels, II – 50 patients – the control group, including 24 women and 26 men aged 20–71 years without dizziness and/or hearing disorders and without disturbance in the construction of intracranial vessels. For each patient, the following tests were carried out: subjective, objective otorhinolaryngological, Doppler ultrasound specifying the diameter of vertebral and carotid arteries and the velocity of blood flow in these vessels, audiological diagnostics, including the examination of latency of waves I, III, V of the auditory evoked potentials of the brain stem, otoneurological diagnostics with used the neck torsion test. Results. It appears from the analysis of the material presented that the application of the neck torsion test in the Doppler ultrasound results in the fact that the difference in the mean systolic velocity of blood flow in vertebral artery is higher on the side opposite to the turning of the neck, and the increase in the average diastolic blood flow velocity in the vertebral artery on the side of the test being performed and its reduction on the opposite side in the study group, when compared to the control group. The value of the wave I, II, V latency in the ABR test during the neck torsion test is extended more in the study group than in the controls, on the side of the performed test. The performed neck torsion test in the VNG test increases the occurrence of both, square waves and nystagmus (much higher in the study group than in the controls). Conclusion. The application of the neck torsion test in the Doppler ultrasound, ABR and VNG test in patients with vertigo and/or hearing loss means that these tests become functional, thereby increasing their diagnostic value and may be used to monitor the rehabilitation of inner ear disorders.
