Theoretical study of the threshing process of corn cob under the influence of the rasp bars

Abstract The device described in this scientific article can be used to cut off the unnecessary (top and bottom) part of the corn ears grown for seed, and to thresh and separate the seeds of the precise size. In the course of our research, it was determined that the speed of rotation of the ear corn after impact Ucr , the radius of the drum Rd , the angular velocity ωr of the drum at what number of revolutions, the angular speed ωcr of the ear corn after impact, and how it affects the threshing process. According to the physical meaning of the established inequality, the ear corn does not advance from the threshing rasp bar under the impact of the strike of the threshing rasp bar, on the contrary, the threshing rasp bar passes over the corn ear and threshes or removes the seed grains. Also, during the research, Vc and Vrbr speeds were analyzed from a theoretical point of view, and their influence on the technological process was studied.

Estimation of outer-wall length in optimizing cochlear implantation in malformed inner ears

Estimation of cochlear length is gaining attention in the field of cochlear implants (CIs), mainly for selecting of CI electrode lengths. The currently available tools to estimate the cochlear duct length (CDL) are only valid for normal inner anatomy. However, inner ear malformation (IEM) types are associated with different degrees of cystic apices, limiting the application of CDL equations of normal anatomy inner ear. Therefore, this study aimed to understand the degree to which the outer wall (OW) is observed in different malformation types and to formulate mathematical equations to estimate the OW length (OWL) from cochlear parameters, namely the basal turn diameter (A-value) and width (B-value). Three-dimensional (3D) segmentation of promontory and fluid parts of the inner ear was performed to understand the extent to which the OW is visible to measure the OWL manually. Enlarged vestibular aqueduct syndrome (EVAS) was diagnosed in 37 ears, which consistently showed the extent of the OW to an angular depth of 540°, beyond which the cystic apex starts. Incomplete partition (IP) type I was observed in 30 ears, with the OW extending to only 360° of angular depth. IP type II was observed in 35 ears, with the OW extending to 450° of angular depth. IP type III was identified in 24 ears, with the OW observed for 540° of angular depth. Cavity-type malformations were observed in 36 ears, and circumference was measured in the axial view. A strong positive linear correlation was observed between the manually measured OWL and cochlear parameters for all malformation types analyzed. A multiple linear regression model was applied to formulate mathematical equations, which was further used to create a software application for estimating OWLs in IEM types, using cochlear parameters as inputs.

Possible causes of vertigo attacks in Meniere’s disease

Various types of nystagmus during vertigo attacks in Meniere’s disease (MD) include direction-changing and non-direction-changing nystagmus. The direction-changing and non-direction-changing nystagmus may be associated with how the inner ear balance organs are influenced spatially and temporally. We hypothesized that the density difference inside the endolymph elicits the stereocilia inclination of the inner ear balance organs even if the density difference area does not directly touch the stereocilia. The direction of the nystagmus could change if the density difference area spreads around the inner ear balance organs. Numerous records of the nystagmus direction with new devices from the beginning of the nystagmus during the vertigo attacks will contribute to understanding how vertigo attacks appear in MD. The influence of the density difference may be associated with the degree of endolymphatic hydrops. Under significant endolymphatic hydrops, the volume effect due to the density difference becomes more prominent. The trabecular meshwork located in the perilymph in the superior part of the inner ear may maintain the perilymphatic space and prevent the enlargement of the endolymphatic space.

Streptomycin generates oxidative stress in melanin-producing cells: In vitro study with EPR spectroscopy evidence

Streptomycin (STR) is an aminoglycoside antibiotic with a broad-spectrum of activity and ototoxic potential. The mechanism of STR-induced inner ear damage has not been fully elucidated. It was previously found that STR binds to melanin, which may result in the accumulation of the drug in melanin-containing tissues. Melanin pigment is present in various parts of the inner ear, including the cochlea and vestibular organ.The present study aimed to assess if streptomycin generates oxidative stress and affects melanogenesis in normal human melanocytes. Moreover the variation of free radical concentration in STR-treated melanocytes was examined by electron paramagnetic resonance spectroscopy (EPR). We found that STR decreases cell metabolic activity and reduces melanin content. The observed changes in the activity of antioxidant enzymes activity in HEMn-DPs treated with streptomycin may suggest that the drug affects redox homeostasis in melanocytes. In this work EPR study expanded knowledge about free radicals in interactions of STR and melanin in melanocytes. The results may help elucidate the mechanisms of STR toxicity on pigment cells, including melanin-producing cells in the inner ear. This is important because understanding the mechanism of STR-induced ototoxicity would be helpful in developing new therapeutic strategies to protect patients' hearing.

Экономическое обоснование уборки зерновых культур ранних фаз спелости очесом и приготовления корма из необмолоченного вороха

Abstract. The stripping of grain allows organizing the separate harvesting of grain for feed in early phases and for food purposes in the phase of full ripeness. Purpose. To carry out the economic justification of the technology of harvesting early ripening grains by stripping without threshing and the technology of preparing pelleted fish feed for fish from unthreshed ears and additives. Methods. Economical estimation of the technology of winter wheat harvesting by stripping in early phases of ripeness without threshing and its processing into feed has been carried out by comparing operational and indicated expenses of the total technological operations. Scientific novelty lies in the joint estimation of the economic efficiency of technologies of harvesting and processing of grain crops. Results. The prime cost of harvesting cereals without threshing and separation is 2.65 times lower than that of the harvesting technology with combine threshing and separation. The cost of performing operations under the traditional (from grain) and the new (from ears) technologies of pelleted fish feed production is almost equal. However, the total cost of technological operations of harvesting grain without threshing and preparation of pelleted feed from unthreshed ears using the new technology is 24.3 % lower than that of traditional technology of harvesting with threshing and preparation of feed from grain. The use of non-grain part of ears of early ripeness in the composition of feed will increase the amount of raw material from hectare of sown area by 20–30 %. The proposed technologies is cost-effective and promising for implementation in the agricultural enterprises of southern Russia.

Immuno-surveillance and protection of the human cochlea.

Despite its location near infection-prone areas, the human inner ear demonstrates remarkable resilience. This suggests that there are inherent instruments deterring the invasion and spread of pathogens into the inner ear. Here, we combined high-resolution light microscopy, super-resolution immunohistochemistry (SR-SIM) and synchrotron phase contrast imaging (SR-PCI) to identify the protection and barrier systems in the various parts of the human inner ear, focusing on the lateral wall, spiral ganglion, and endolymphatic sac. Light microscopy was conducted on mid-modiolar, semi-thin sections, after direct glutaraldehyde/osmium tetroxide fixation. The tonotopic locations were estimated using SR-PCI and 3D reconstruction in cadaveric specimens. The sections were analyzed for leucocyte and macrophage activity, and the results were correlated with immunohistochemistry using confocal microscopy and SR-SIM. Light microscopy revealed unprecedented preservation of cell anatomy and several macrophage-like cells that were localized in the cochlea. Immunohistochemistry demonstrated IBA1 cells frequently co-expressing MHC II in the spiral ganglion, nerve fibers, lateral wall, spiral limbus, and tympanic covering layer at all cochlear turns as well as in the endolymphatic sac. RNAscope assays revealed extensive expression of fractalkine gene transcripts in type I spiral ganglion cells. CD4 and CD8 cells occasionally surrounded blood vessels in the modiolus and lateral wall. TMEM119 and P2Y12 were not expressed, indicating that the cells labeled with IBA1 were not microglia. The round window niche, compact basilar membrane, and secondary spiral lamina may form protective shields in the cochlear base. The results suggest that the human cochlea is surveilled by dwelling and circulating immune cells. Resident and blood-borne macrophages may initiate protective immune responses via chemokine signaling in the lateral wall, spiral lamina, and spiral ganglion at different frequency locations. Synchrotron imaging revealed intriguing protective barriers in the base of the cochlea. The role of the endolymphatic sac in human inner ear innate and adaptive immunity is discussed.

Reconstruction of Partial Defect of Ear in a Tertiary Care Institute.

Auricle is the outward visible part of ear and composed of skin and cartilage. Auricle due to its standout and projected position is more vulnerable to get injured and cause distortion of the facial aesthetics. Reconstruction of the ear defect should be individualized depending on the defect size, location, nearby skin, patient requirement and surgeon experience. To present the results of various reconstructive options for partial ear defect which will aid in decision making among reconstructive options available. Reconstruction was individualized considering the defect size, depth, location, surrounding skin. In upper 1/3 defect reconstructive options include Antia-Buch chondrocutaneous advancement flap, autogenous cartilage with temporoparietal fascial flap, for middle 1/3 defect options include retroauricular soft tissue tube flap, diefenbach procedure, Autogenous cartilage graft and temporoparietal fascial flap, for lower 1/3 defect reconstructive options include pre auricular flap, triangular repair method, Zenteno Alanis technique. Reconstruction with various techniques results in aesthetically good outcomes. There is no major complication seen in any patient. Reconstruction of ear defect with various options available has good outcome. Planning is important part in reconstruction process. Reconstructive option chosen for a ear defect should be individualized depending on patient characteristics, surgeon experience.

Appropriate Vestibular Stimulation in Children and Adolescents-A Prerequisite for Normal Cognitive, Motor Development and Bodily Homeostasis-A Review.

The structural development of the vestibular part of the inner ear is completed by birth but its central connections continue to develop until adolescence. Their development is dependent on vestibular stimulation-vestibular experience. Studies have shown that vestibular function, modulated by experience and epigenetic factors, is not solely an instrument for body position regulation, navigation, and stabilization of the head and images but also influences cognition, emotion, the autonomous nervous system and hormones. To emphasize the importance of appropriate vestibular stimulation, we present a literature review of its effect on bodily homeostasis, cognition and emotion.

Evaluation of the efficacy and tolerability of the combination of lidocaine + phenazone in the local therapy of acute otitis media at the doperforative stage in adults

Introduction. Acute otitis media is a widespread multifactorial disease characterized by inflammatory changes in the mucosa of all parts of the middle ear. One of the most important tasks in the early stages of the disease is adequate anesthesia of patients. The article provides a retrospective assessment of the efficacy (speed of analgesia) and tolerability of topical use of Otipax® (lidocaine + phenazone) in adult patients with acute otitis media before perforation, the timing of its use is justified.Aim. To assess the efficacy and tolerability of topical Otipax® in adult patients with pre-perforated acute otitis media prescribed by a physician in routine practice.Materials and methods. Outpatient maps of 50 adult patients with acute otitis media were analyzed.Results. In almost all 50 patients after the use of Otipax®, the analgesic effect occurred after 3 minutes. The analgesic effect remained on average for 35–40 minutes, then the pain gradually resumed, but in dynamics there was a decrease in its intensity. Hearing loss and ear congestion were initially noted in all patients, by the 3rd visit these complaints persisted, but their intensity was significantly lower, on the 10th day of observation there were no subjectively impaired hearing in any of the patients, which corresponded to acumetric and tuning fork data. The anti-inflammatory effect of Otipax® after a day provided a significant decrease in the intensity and area of hyperemia and infiltration of the eardrum. After 10 days, almost all patients had no otoscopic signs of otitis media. No adverse events were reported during the follow-up period.Conclusions. The use of Otipax® (lidocaine + phenazone) ear drops complies with the clinical guidelines of the Ministry of Health of the Russian Federation in 2021 for the treatment of patients with acute otitis media before perforation, effectively and safely, is the method of choice for reducing ear pain in patients already at the primary appointment.

Suicide by sharp force associated with major self-mutilation and self-cannibalism.

Self-stabbing and self-cutting represents an uncommon method of suicide. We present a case of a 30-year-old man who was found dead in the forest. The body was naked and showed multiple cut and stab wounds on different parts of the body (face, neck, chest, abdomen, and extremities). A single-edged kitchen knife was found approximately 20m from the body. Parts of both ears, the fifth toe of the right foot, and the scrotum were cut off. At the autopsy, two of the severed body parts-the toe and the part of the left ear-were found in the stomach. The cause of death was asphyxiation due to blood aspiration resulting from a cut throat injury. A police investigation uncovered a history of substance abuse and two previous suicidal attempts using a knife. Upon complex analysis of all the evidence, the manner of death was ruled a suicide, which was preceded by actions of major self-mutilation and self-cannibalism, both considered rare behavioral patterns.

Ontogenetic changes in sagitta otoliths of whitemouth croaker Micropogonias furnieri (Acanthuriformes: Sciaenidae) and its implication in acoustic communication

Abstract The otoliths of teleosts are part of the inner ear. They are related to the balance system and are also mechanical components of sound transmission, responsible for hearing in fish. Their morphology is determined by the function they perform and is also influenced by environmental factors. In this context, our goal was to: analyse the possible morphological changes of sagitta otoliths of Micropogonias furnieri (Desmarest, 1823) during its ontogeny, based on six biometric indexes. We analysed 162 sagittae otoliths of Micropogonias furnieri collected in the Rio de la Plata estuary. The variation of the indexes was associated with the different size groups. Rectangularity and aspect ratio [otolith length/total fish length (OL/TL) and sulcus area/otolith area (SA/OA)] were the indexes that contributed the most to the discriminant function. Biometric index differences were related to diverse juvenile environments. The observed shift in the SA/OA relationship could be attributable to a need to respond to a change in the perception of sound (pulse and frequency) experienced by individuals larger than 20 cm that begin to frequent the same areas as spawning adults. In this sense, the ontogenetic morphological change of sagitta otoliths plays an important role in perception and acoustic communication for this species.

Elderly onset atypical Lemierre’s syndrome concurrent with a rheumatoid vasculitis sacral ulcer infection: a case report

BackgroundTypical Lemierre’s syndrome is usually secondary to an oropharyngeal infection. Recently, several cases following a primary infection site other than the oropharynx have been reported as atypical Lemierre’s syndrome; although, these primary lesions are limited to the head and neck. This is the first case potentially sequential to infectious foci outside the head and neck.Case presentationWe describe an atypical Lemierre’s syndrome in a 72-year-old woman with rheumatoid arthritis, which occurred during the treatment of Streptococcus anginosus bacteremia acquired from a sacral ulcer infection related to rheumatoid vasculitis. At first, the symptoms resolved after the initial administration of vancomycin for the bacteremia caused by methicillin-resistant Staphylococcus aureus and Streptococcus anginosus that entered via a sacral ulcer. On the 8th day, the patient developed a fever of 40 °C and unexpectedly required 10 L of oxygen due to rapid deterioration of oxygenation temporarily. Immediately contrast-enhanced computed tomography was performed to investigate systemic thrombosis including pulmonary embolism. Afterward, the newly formed thrombi at the right external jugular vein, bilateral internal jugular veins, and the right small saphenous vein were detected, and apixaban was started. On the 9th day, the patient again had an intermittent fever of 39.7 °C, and continuous Streptococcus anginosus bacteremia was revealed; subsequently, clindamycin was administered. On the 10th day, she developed a left hemothorax; consequently, apixaban was discontinued, and a thoracic drain was inserted. She repeatedly had an intermittent fever of 40.3 °C, and contrast-enhanced computed tomography detected an abscess formation at the left parotid gland, pterygoid muscle group, and masseter muscle. After Lemierre’s syndrome was diagnosed in combination with the abovementioned jugular vein thrombus, clindamycin was replaced with meropenem, and vancomycin was increased. Swelling of the lower part of the left ear became prominent with delay and peaked at approximately the 16th day. The subsequent treatment course was favorable, and she was discharged on the 41st day.ConclusionClinicians should consider Lemierre’s syndrome as the differential diagnosis of internal jugular vein thrombosis occurring during sepsis, even though an antibiotic is administered or a primary infection site is anything besides the oropharynx.

Vestibular anomalies and dysfunctions in children with inner ear malformations: A narrative review.

About 20% of children with congenital hearing loss present malformations of the inner ear. In the past few years much has been understood about the morphology and function of the anterior part of the labyrinth, since hearing loss may have a dramatic effect on the overall development of a child. Nowadays, for most of them, a chance for hearing rehabilitation is available, making hearing loss a treatable condition. The anomalies range from the lack of development of the whole inner ear to specific anomalies of isolated structures. Despite the frequent concomitant involvement of the posterior part of the labyrinth, this part of the inner ear is frequently neglected while discussing its morphology and dysfunction. Even though vestibular and balance function/dysfunction may have a significant impact on the global development of children, very little is known about these specific disorders in patients with inner ear malformations. The aim of this review is to summarize the available literature about vestibular anomalies and dysfunctions in children with inner ear malformations, discussing what is currently known about the topic.

Thermal imaging and physiological responses of crossbred goats under different housing system during hot humid season

In order to observe the effect of hot humid (July-August) season on physiological responses and skin surface temperature, eighteen adult female crossbred goats were selected divided equally into three groups i.e. Group I (control), Group II(modified shed) and Group III (open environment) based on their body weight. These animals were fed as per the standard feeding schedule followed at NDRI, Karnal. The average respiration rate of group I, II and III was 76.11±1.03, 67.22±0.06 and 70.49±0.61per minute respectively during morning hours. The RR increased significantly during afternoon over morning values in all the groups due to increase of THI. The rectal temperature of goats during morning hours was 38.73±0.02, 38.57±0.03 and38.68±0.03°C in group I, II and III respectively and no significant change in RT was observed during the afternoon. The overall lowest and highest skin temperature were recorded at the lower part of legs and ears respectively in group I and II, whereas ingroup III the highest skin temperatures was found to be at dorsal and lowest at ventral region of the body. The information generated may serve as normal reference values for crossbred goats under different housing conditions and may be useful for predicting the animal welfare and prognosis of diseases.

Morphological and Metric Identification of Earprint between Sexes

The observable morphological features of the outer ear are used in criminal investigations. An ear print is a two-dimensional replica of the parts of the outer ear (such as the helix, antihelix, tragus, and antitragus) that contact the surface and create pressure. It is often found in burglary cases (breaking into the home or workplace). Although the unique structure of the ear and its usefulness in identification has been recognised by researchers, there are very few studies in which its uniqueness is stated with certainty. There is no numerically precise data on which these studies are based. As the number of sources in the literature is limited and does not provide the expected results with certainty, this study aims to fill this gap in the relevant literature. In the study, the ear prints of the subjects were taken by a printing method, digitised, and analysed from a forensic point of view. The individual-specific structure of the external ear morphology was analysed based on observational and metric measurements, and a reliable database was presented for future studies.

Применение компьютерной томографии височных костей в планировании и оценке эффективности реконструктивной хирургии среднего уха

One of the possible methods of eliminating the trephine defect after performing open-type operations on the middle ear in patients with suppurative otitis media is obliteration of the cavities of the middle ear with fat tissue. There are no references to radiological assessment of emerging changes when using this technique in the domestic and foreign literature, which dictates the need to develop predictors of negative results in the early postoperative period. We have studied the possibility of using computed tomography (CT) of the temporal bones to evaluate a fat implant in order to predict the outcome of reconstructive intervention during obliteration of the retrotympanic parts of the middle ear with fat tissue. All patients underwent control CT examinations 1, 3, 6, and 12 months after surgery. Depending on the clinical manifestations in the postoperative period, the examined patients were divided into three groups. As a result of the study, the analysis of the CT picture showed that an increase in the density characteristics of the autograft and the appearance of small gas bubbles in the early postoperative period are not a predictor of the negative result of the surgery. Whereas the CT picture of the presence of a large amount of gas and, as a consequence, the absence of a well-formed fat sac already in the early postoperative period were harbingers of the negative outcome of the surgery. Thus, obliteration of the middle ear cavity by auto-fat is a reliable method of treatment of chronic purulent otitis media; therefore, further integration of this technique into clinical practice with the use of CT of temporal bones is planned.

Audiovestibular Consequences of Congenital Cytomegalovirus Infection: Greater Vulnerability of the Vestibular Part of the Inner Ear.

To investigate the impact of congenital cytomegalovirus infection on cochlear and vestibular function. This retrospective study conducted between March 2014 and March 2020 included children with confirmed congenital cytomegalovirus infection who underwent a complete audio-vestibular evaluation. It included a bithermal caloric test, a video head impulse test and a cervical vestibular evoked myogenic potential associated with a complete hearing assessment. The cohort of 130 children included in the study had a median age of 21 months (interquartile range: 12 to 37 months). Eighty-three children (64%) showed an inner ear impairment (both cochlear and vestibular). The vestibular part of the inner ear was significantly more frequently impaired than the cochlear part (ρ = 0.003). Sixty-two children (48%) showed confirmed hearing impairment. The severity of hearing loss was variable, with a high proportion of profound hearing loss (30/62, 48%), which was often bilateral (47/62, 76%). The vestibular assessment showed a canal function disorder in 67 children (88%) and an otolith function disorder in 63 children (83%; ρ = 0.36). The video head impulse test was significantly less altered (64%) compared with the bithermal caloric test (80%; ρ = 0.02) and the cervical vestibular evoked myogenic potential (83%; ρ = 0.009). Only seven out of 83 children (8%) showed hearing loss without vestibular dysfunction, of which only one had a normal hearing screening test at birth. For the children who passed the hearing screening test at birth and presented an inner ear impairment [n = 36, median age: 16 (11 to 34) months], vestibular disorders were later found in 35 children (97%) and 17 of them (47%) developed hearing loss secondarily. This underlines the importance of assessing both vestibular and auditory parts of the inner ear. When comparing the agreement of cochlear and vestibular impairment, the severity and the laterality of the impairment were low [Cohen's kappa 0.31 (0.22 to 0.40) and 0.43 (0.32 to 0.55), respectively]. In our study, we demonstrated that although both cochlear and vestibular parts of the inner ear can be impaired by congenital cytomegalovirus infection, the vestibular part seems more often impaired compared with the cochlear part. This underlines the importance of vestibular evaluation in the follow-up of cytomegalovirus-infected children associated with hearing assessment.

Surgeon’s decision concerning limb amputation after frostbite as a basis of subsequent successful activity of general practitioner-family physician (own clinical observations and experience of education in state and English language)

The degree of frostbite depends on environment temperature, cold wind and the duration of exposition. Tissue freezing after the loss of warmth and appearing of ice crystals in superficial and deep tissues are in the basis of frostbite. Because of easy access and peripheral anatomic features frostbites preferably involve distant upper and lower parts of limbs, ears, nose and cheeks. There are wide spectrum of clinical manifestations of frostbites in the range of lesions, which disappear to lesions, which require amputations. Such classification of lesions clinical characteristics is a working classification basing on degree of injury. Even without tissue losses patients may suffer of long-term consequences after frostbites, which can include vasomotor disorders, neuropathic and nociceptive pain and arthritis after frostbites. Article describes own clinical observations of very severe (ending with amputation) frostbite case. We consider submitted description as an informative for discussion during practical classes in state and English languages. Making in time and saving amputation by the surgeon is a very important aspect for the long-term management of patient by primary care physician following rehabilitation program including all necessary vital prescriptions. Described approach to our patient was based on long-term development of manifestations with precise demarcation line and joining of purulent process after frostbite up to the time of his conscious appeal for medical help.

Promising Outcome of Radiation Therapy for Chondroblastoma of Temporal Bone in Childhood: A Case Report

Chondroblastoma is a rare cartilaginous benign bone tumor. Chondroblastoma in the temporal bone is also quite rare. Total excision is the main treatment. Data regarding tumor response to radiation therapy (RT) is insufficient. We describe a case of chondroblastoma that was treated with RT following subtotal tumor resection. In this case, the patient was a 14-year-old male who presented with a three-month history of ear fullness and hearing loss in his right ear. Magnetic resonance imaging revealed a mass partly filling the right external auditory canal and the inferior part of the middle ear. Histopathological findings indicated chondroblastoma. Subtotal tumor resection was performed due to risk of complications. RT was planned upon the growth of the tumor during follow-up. Treatment with subtotal resection and postoperative RT has been successful and the patient had no recurrence in the course of the 12-year follow-up. In chondroblastoma, complete surgical resection is still the gold standard. But the success of subtotal resection followed by adjuvant RT should also be kept in mind for cases where the total excision would pose high morbidity.

Audiological profile and handicap levels in people with vestibular disorders at Centro Equilibra, Vértigo and Equilibrio, San José, Costa Rica

Background and objectiveVestibular disorders are linked to a group of pathologies that can affect the vestibular part, the auditory part, or both parts of the inner ear. The problem in this study is the little information that exists about the audiological profile of people suffering from vestibular disorders in Costa Rica. There are international research studies on this topic, but there are no records of studies conducted in the Costa Rican population. This is why there is interest in developing this research which aims to characterize the audiological profile and the levels of handicap in people with vestibular disorders under Centro Equilibra, Vertigo and Equilibrio consultation during the months of September to November 2019. Patients and methodsA descriptive, cross-sectional, quantitative, and observational analytical study with patients over 18 years old who attended Centro Equilibra. The main variables analysed were sex, age, personal pathological history, medical diagnosis, main vestibular symptoms, auditory manifestations, and levels of handicap. ResultsThe data was obtained from 177 people; vestibular disorders occurred more in the female sex (ratio 2.6:1). The mean age was 56 years. Fifty-three point seven percent presented slight sensorineural hearing loss, gradually decreasing. Of the population, 33.9% presented tinnitus, mostly at high frequencies. In the adult population, 52% presented some level of hearing handicap, unlike older adults, where the majority (77%) did not present any level of handicap. People with vestibular disorders perceive greater physical handicap (83%). ConclusionsHearing loss was the most common hearing manifestation and although statistical analysis shows that it is not directly related to vestibular disorders, it is related to concomitant metabolic diseases. For this reason, it is necessary to promote the prevention of metabolic diseases as one of the measures to improve hearing health, even from an early age.
