The Variability of function of the Eustachian tube in patients with chronic sinusitis.

BackgroundThe Eustachian tube is a complex and inaccessible structure, which is responsible for the ventilation of the middle ear. The aim of the study was the assessment of an impact of chronic sinusitis on the auditory tube function. MethodsThe prospective analysis of 84 surgically treated chronic sinusitis patients was carried out. This study is based on preoperative results of impedance audiometry in correlation with the data from the medical history of chronic sinusitis, symptoms reported by the patients, results of Computered Tomography (CT) and the stage of inflammatory changes according to Lund and Mackay score. ResultsThe significant majority of patients of our study (65) had advanced auditory tube symptoms, while 4 patients suffered from symptoms significantly impacting daily life. In patients with chronic sinusitis the analysis demonstrated that tympanometry type B (12.67) and C (12.4) occured with significantly higher number of points of Lund-Mackay score than type A (9.2). In allergy sufferers type B of tympanometry was more often observed with characteristically bilaterally located inflammatory changes in maxillary and anterior ethmoid sinuses.ConclusionThe profile of chronic sinusitis patient in whom Eustachian Tube Dysfunction is more often observed, is as follows: Lund and Mackay score above 12pathological changes are bilaterally observed in maxillary and frontal ethmoid sinuses decrease of nasal patency nad postnasal dripAllergyoverusing alcohol and cigarettes, at least alcoholWorse result of Lund and Mackay score and the age of patients are 2 factors favoring the dysfunction of the Eustachian Tube.

Association between Sudden Sensorineural Hearing Loss and Lyme Disease.

OBJECTIVES: Sudden sensorineural hearing loss (SSNHL) is defined as sensorineural hearing loss of 30 dB or more over at least three adjacent audiometric frequencies occurring within a 72-h period of time. One of the causes of SSNHL could be the progressive inflammatory state caused by an infection. The aim of this study was to assess the prevalence of SSNHL caused by various factors, most importantly those potentially related to Lyme disease. MATERIAL AND METHODS: The study includes a group of 86 patients between the ages of 20 and 70 who were hospitalized due to SSNHL between 2017 and 2018. All of these patients underwent a detailed medical interview and an otolaryngological examination, including audiological and diagnostic tests. Additionally, ELISA and Western blot tests were performed to confirm the diagnosis of Lyme disease. RESULTS: In this group of 86 patients, nine patients presented with positive antibodies toward Borrelia burgdorferi sensu lato. This group was treated with antibiotics and experienced partial or complete regression of their deafness. This may suggest a relationship between SSNHL and Lyme disease. CONCLUSION: Infections caused by Borrelia burgdorferi may contribute to the development of inflammatory and angiopathic lesions, which are a possible cause of SSNHL. The longer the duration of the infection, the greater the likelihood of permanent and irreversible changes in the vessels of the cochlea or auditory nerve. Therefore, serological tests for Borrelia burgdorferi should be performed during the diagnosis of SSNHL as a possible cause of this illness.

Does the short-term exposure to radiofrequency electromagnetic field originating from mobile phone affect auditory functions as measured by Acoustic Admittance and Evoked Otoacoustic Emission tests?

BACKGROUND: Mobile phones constitute an important source of radiofrequency electromagnetic field (RF-EMF) for humans. Taking into account high sensitivity of sensory hair cells of the inner ear to endogenous and exogenous agents, the potential impact of mobile phone usage on auditory organs is of particular interest. AIM: The aim of the study was to evaluate the impact of short-term exposure to RF-EMF generated by a mobile phone during 15-minute simulated phone call on human hearing as measured by Transient Evoked Otoacoustic Emission (TEOAE) and Acoustic Admittance Testing (AAT). MATERIAL AND METHODS: Within-subject study was performed on 23 healthy volunteers. All of the participants underwent TEOAE and AAT before and immediately after 15-minute simulated phone call with the use of a standard, modern smartphone. Analyzed parameters included: static compliance of tympanic membrane, middle ear pressure, ipsi- and contralateral acoustic reflex thresholds and percentage of signal reproducibility in TEOAE for exposed and non-exposed ear. Additionally, the results were compared in subgroups distinguished basing on self-reported sensitivity to RF-EMF originating from mobile phones. RESULTS: No statistically significant differences were identified between results of TEOAE and AAT before and after exposure, both in exposed and non-exposed ear. The results of EMF sensitive and non-sensitive subjects were comparable in all performed tests. CONCLUSIONS: Short-term exposure to mobile phone electromagnetic field did not influence auditory functions as measured by Evoked Otoacoustic Emission test and Acoustic Admittance Testing.

Stability of ABR Wave V Threshold in Early Hearing Diagnostics in Children from Selected Groups at Risk of Congenital Hearing Loss.

<b>Introduction:</b> Upon hearing that the "little" patient has trouble with hearing, we are mostly interested in the level of his hearing threshold. When the child is in the first year of life, results can only be achieved by means of ABR test. Subsequent control tests, especially in children from the hearing loss risk groups selected in this study, show that the obtained outcomes are subject to fluctuations. Their fluctuating nature is manifested by the instability of wave V threshold in subsequent diagnostic periods. Such variability often delays the implementation of the appropriate proceeding. Knowledge of the dissimilarity of behavior of the wave V threshold occurring in individual groups at risk of hearing loss allows for the correct interpretation of the obtained results, and thus, effective therapeutic measures. <br><b>Aim:</b> The aim of the paper is to analyze the stability of wave V threshold during the first year of life in children from selected risk groups for congenital hearing disorders. <br><b>Material and methods:</b> From the patient population of 2,114 individuals examined in 2015-2016 at a reference center participating in the Universal Neonatal Hearing Screening Program in 2015-2016, the results of 250 children were subjected to retrospective analysis. Furthermore, 4 groups of little patients were formed (children with Down syndrome; children with other diseases or damage to the nervous system; children with cleft palate or cleft lip and cleft palate; children with congenital cytomegaly) in whom diagnostic practice revealed variable results of the wave V threshold. We analyzed the results of tests obtained during the first year of the child's life divided into 4 diagnostic periods. <br><b>Results:</b> The highest percentage of instability in the established threshold of wave V between individual diagnostic periods occurred in the group of children with cleft palate or cleft lip and cleft palate. In the group of children with Down syndrome, it was observed that the instability of the ABR test results decreased over time. In the group of children with other diseases or damage of the nervous system, the highest percentage of the lack of stable ABR wave V thresholds was observed between the 1st and 2nd as well the 1st and 4th diagnostic periods. On the other hand, in the group of children with congenital CMV, there was a relatively low percentage of instability of results. <br><b>Conclusions:</b> (1) Although the ABR test is a diagnostic standard, in particular groups of patients the study is burdened with high variability of measurement results in subsequent diagnostic periods. Such a group of patients are children with cleft palate or cleft lip and cleft palate; therefore, it must receive particular attention in treatment planning; (2) in selected groups at risk of hearing loss, due to the high percentage of children with hearing impairment (70%), the validity of performing newborn hearing screening tests was confirmed.

Analysis of diagnostic-therapeutic results after the first year of life in children of hearing disturbance risk groups.

INTRODUCTION: It is assumed that the critical period for diagnosis of hearing disorders is the baby's first three months of life and that appropriate course and implementation of treatment and/or rehabilitation should begin before a child is six months old. However various kinds of problems may occur during auditory screening of a child may exceed this interval. AIM: The aim of this study was an evaluation of auditory screening results for children over 12 months old with congenital hearing loss. MATERIAL AND METHODS: Results from 250 children were analyzed retrospectively. The study group consisted of children between one and three months old observed between 2015-2016. For the purpose of this analysis we divided the patients into four groups: children with Down Syndrome, children with nervous system disorders , children with cleft palate or both cleft palate and lip and children with congenital CMV. To discuss performed diagnostics and treatment two groups of children were esteblished: • with implementation of appropriate course of treatment • without instituted treatment Results: 250 children were examined in Level III NICUs in the years 2015 - 2016. The highest proportion of children with the implemented course of proceedings, was in groups with children with congenital CMV (71.1%). The highest proportion of children substituted with a hearing prosthesis was observed in the group of children with Down Syndrome. The lowest proportion of children with the implemented course of proceedings, was in groups with children with cleft palate or both cleft palate and lip (41.6%). CONCLUSIONS: • Early implementation of treatment and/or rehabilitation in children with hearing disorders is crucial to prevent depression of speech and psychological development. I t is important in children with cleft palate or both cleft palate and lip even if surgical correction is discussed. • The highest proportion of children with the implemented course of proceedings, was in groups with children with congenital CMV. This children should be observed despite of right results of hearing tests. • In children with nervous system disorders 1 year period of observation is too short to exclude problems with hearing.

Factors that have an influence on bone conduction thresholds changes after otosurgery in the patients operated on due to the perforation of the tympanic membrane with the preserved ossicular chain.

INTRODUCTION: The aim of the middle ear surgery is to eliminate abnormalities from the mucous, ensure the due airing of the postoperative cavity and reconstruct the sound-conducting system in the middle ear. Numerous reports can be found in literature on the changes to bone conduction as a consequence of middle ear surgery. STUDY OBJECTIVE: The aim of the work is to define the factors that affect bone conduction in the patients operated on due to the perforation of the tympanic membrane with the preserved and normal mobile ossicular chain. MATERIAL AND METHOD: A prospective analysis of patients operated on due to diseases of the middle ear in 2009-2012 was carried out. The cases of patients operated on for the first time due to chronic otitis media were taken into consideration. The analysis encompassed the patients who had undergone myringoplasty. The patients were divided into several groups taking into account the abnormalities of the mucous observed during otosurgery. RESULTS: A significant improvement of bone conduction was observed in the patients with dry perforation, without other lesions in the middle ear. The appropriate pharmacological treatment before otosurgery in patients with permanent discharge from the ear resulted in significant bone conduction improvement. The elimination of granulation lesions turned out to be a positive factor for the future improvement of the function of the inner ear. CONCLUSIONS: The lack of abnormalities on the mucous of the middle ear (e.g. granulation,) and discharge has a positive impact on improvement of bone conduction after myringoplasty. Adhesions in the tympanic cavity, especially in the niche of the round window, have a negative impact on improvement of bone conduction in patients after myringoplasty.

Analysis of difficulties occurring during the early auditory screening in children.

INTRODUCTION: It is assumed that the critical period for diagnosis of hearing disorders is the baby's first three months of life and that appropriate course and implementation of treatment and/or rehabilitation should begin before a child is six months old. However various kinds of problems may occur during auditory screening of a child may exceed this interval. This problem is particularly pronounced among children with development and health problems and leads to unreliable and varied results. AIM: The aim of this study was an analysis of prevalence of difficulties occurring during the first year of auditory screening among groups of children with congenital hearing impairment. MATERIAL AND METHODS: Patients were examined in The Universal Newborn Hearing Screening Program in the years 2012 - 2013 in Level III NICUs in Krakow. Results from 250 cases were analyzed retrospectively. Medical exam results of patients with high risk of hearing loss were also included in our analysis. The groups of children included in our study were: children with Down Syndrome, children with nervous system disorders , children with cleft palate or both cleft palate and lip and children with congenital CMV. RESULTS: In the group of children with cleft palate or both cleft palate and lip the most frequent cause of not conducting objective audiometric tests was bad health condition of a child which precluded his arrival for administering the tests. The most common cause of difficulties in performing hearing tests was the emotional state of children from groups with Down Syndrome. In the group of children with congenital CMV the most common cause of difficulties was a lack of availability of their parents. CONCLUSIONS: 1. We encountered the greatest diagnostic difficulties during the child's first year of life in chosen high-risk groups of children with congenital hearing loss in children with cleft palate or both cleft palate and lip. 2. The highest prevalence of not finished tests was in III and IV interval for all chosen high-risk groups with congenital hearing loss.

[Response changes of inner ear observed after middle ear surgery]. / Zmiana odpowiedzi ucha wewnetrznego obserwowana po operacjach na uchu srodkowym.

BACKGROUND: Relationship beetwen middle ear surgery and function of the inner ear is known. This problem is often discussed in determination of hearing improvement after otosurgery. AIM: Usefulness of the click evoked otoacoustic emissions (CEOAE) in evaluation of the inner ear function and effectiveness of tympanoplasties is discussed. MATERIAL AND METHODS: Prospective analysis of 70 individuals operated on middle ear problems was performed. Patients were divided into four groups of otosurgeries: stapedoplasty, myringoplasty, type II tympanoplasty, type III tympanoplasty. Otoacoustic emissions and pure tones audiometry were performed before middle ear surgery and 3 months after ear operation. RESULTS: In all established groups improvement in ABG (air bone gap) was observed. Improvement of bone conduction thresholds in the ranges of 5dB was observed in individuals with otosclerosis and type I and type III tympanoplasty. Patients with type II tympanoplasty developed no changes of bone conduction threashold after otosurgery. CONCLUSIONS: Behind routine audiometric diagnostics otoacoustic emissions can be useful in postoperative evaluation of effectiveness of middle ear surgery (especially in patients operated on otosclerosis and in individuals with chronic otitis media with intact ossicular chain).

[Analysis of factors affecting the abnormal otoacoustic emissions in infants]. / Analiza czynników majacych wplyw na nieprawidlowy wynik emisji otoakustycznej u niemowlat.

INTRODUCTION: Otoacoustic emissions are routine diagnostics in hearing examination of newborns. Lack of right responses in DPOAE is an indication to father diagnostic procedures to know the reason and institute treatment. AIM: The aim of this paper is analysis of hearing impairment factors in children which are treated in the audiological out-patients ward. MATERIAL AND METHODS: We analyzed retrospectively 168 consecutive children in which diagnostic of hearing apparatus was perform in the first year of life. Children were divided into three groups: with bilateral lack of otoacoustic emissions in newborn ward, with unilateral lack of otoacoustic emissions in newborn ward and with right responses in otoacoustic emissions but with presence of risk factors of hearing impairment in history. RESULTS: In 36 cases results of screening otoacoustic emissions was wrong. Unilateral disturbance of this examination was observed in 24 cases and bilateral in 12 cases. 132 children have right responses in otoacoustic emissions but risk factors of hearing impairment were present. CONCLUSIONS: 1. Immaturity, low birthweight and therapy in intensive care ward are important reasons of disturbance in otoacoustic emissions. 2. Administration of ototoxic medications in pregnancy is the most common risk factor of hearing impairment in children.

[Quality of life in patients treated for cancer of paranasal sinus and other area at head and neck]. / Wplyw dysfagii na jakosc zycia chorych z nowotworami zatok przynosowych i w innych lokalizacjach glowy i szyi.

AIM: The oncology efficiency and quality of life are both important for patients with head and neck cancer in every-day life. MATERIAL AND METHODS: Evaluation of the dysphagia discomfort was made of 240 patients (190 male and 50 female). The primary location of the tumor was: paranasal sinuses, oral cavity, oropharynx, hypopharynx and larynx. The treatment was surgical or sugical and radiotherapy. Patient's quality of life was evaluated according to the self-administered questionnaire (M.D. Anderson Dysphagia Inventory MDADI). RESULTS: The comparison of the influence of dysphagia on the quality of life was made in two groups of patients. The first group consist of maxillectomy patients wearing obturator protheses, the second one were treated for cancer located in other mentioned area. Patients with primary tumors of the oral cavity, oropharynx, hypopharynx and larynx had significantly greater swallowing disability with an adverse impact on their quality of life compared with patients after maxillectomy. Method of treatment and stage of head and neck cancer greatly affected dysphagia-related quality of life. The longer the interval between completion of treatment and assessment by the MDADI, the higher the total score, thus reflecting a higher quality of life and funcional status as related to swallowing. CONCLUSION: The MDADI is the validated and reliable self-administered questionnaire designed specifically for evaluating the impact of dysphagia on the quality of life of patients with head and neck cancer.
