Wideband Tympanometry and Pressurized Otoacoustic Emissions in Children with Surgical Excision of Palatine and/or Pharyngeal Tonsils.

Palatine and pharyngeal tonsil hypertrophy may lead to dysfunction of the auditory tube due to a propensity for infection, potentially giving rise to otitis media. This is a quantitative and longitudinal study, developed from 2019 to 2021, at the State University of Campinas (UNICAMP). The studied sample comprised 15 participants aged 5 to 12 years (mean 7.9 years), 12 male and 3 female, arranged into two groups: children diagnosed with pharyngeal and/or palatine tonsil hypertrophy who were candidates for surgery (G1), and children who were later evaluated after surgery (G2). As part of the test, an otoscopy and measurements of logoaudiometry, pure-tone threshold audiometry, wideband tympanometry (ambient and peak pressure), and otoacoustic emissions (TEOAEs and DPOAEs, both at ambient and peak pressure) were all performed. There were statistically significant differences between phases in pure-tone audiometry, in terms of 226 Hz tympanometry, wideband tympanometry in peak pressure conditions, in the amplitude measurement TEOAEs in both pressure conditions, in DPOAEs in ambient pressure conditions, and in the signal/noise measurement in both pressures in DPOAEs. Overall, it was found that hearing tests were different for subjects with palatine and pharyngeal tonsil hypertrophy compared to the post-surgical group.

Holistic assessment of cochlear implant outcomes using the international classification of functioning disability and health model: data analysis of a longitudinal prospective multicenter study.

PURPOSE: To study outcome after cochlear implantation using the Cochlear Implant (CI) outcome assessment protocol based on the International Classification of Functioning, Disability and Health (ICF) model (CI-ICF). METHODS: Raw data of a prospective, longitudinal, multicenter study was analyzed. Seventy-two CI candidates were assessed preoperatively and six months postoperatively using the CI-ICF protocol. Following tools were used: (1) Work Rehabilitation Questionnaire (WORQ), (2) Abbreviated Profile of Hearing Aid Benefit (APHAB), (3) Audio Processor Satisfaction Questionnaire (APSQ), (4) Speech, Spatial, and Qualities of Hearing Scale (SSQ12), (5) Hearing Implant Sound Quality Index (HISQUI19), (6) Nijmegen CI Questionnaire (NCIQ) (7) pure tone audiometry, (8) speech audiometry, (9) sound localization. RESULTS: There was a significant improvement of speech discrimination in quiet (p = 0.015; p < 0.001) and in noise (p = 0.041; p < 0.001), sound detection (p < 0.001), tinnitus (p = 0.026), listening (p < 0.001), communicating with-receiving-spoken messages (p < 0.001), conversation (p < 0.001), family relationships (p < 0.001), community life (p = 0.019), NCIQ total score and all subdomain scores (p < 0.001). Subjective sound localization significantly improved (p < 0.001), while psychometric sound localization did not. There was no significant subjective deterioration of vestibular functioning and no substantial change in sound aversiveness. CI users reported a high level of implant satisfaction postoperatively. CONCLUSION: This study highlights the positive impact of cochlear implantation on auditory performance, communication, and subjective well-being. The CI-ICF protocol provides a holistic and comprehensive view of the evolution of CI outcomes.

Encoding of speech sounds with frequency-following response in infants with Congenital Zika Syndrome: A case-controlled study

ABSTRACT Purpose: to investigate the frequency-following response (FFR) for sustained neural activity. Methods: 39 individuals, aged between 20 to 47 months old were divided into 2 groups: (i) 20 individuals without prenatal exposure to the congenital Zika syndrome (CZS) or hydrocephaly, normal development, no risk factors for hearing loss or syndromic hearing impairment and (ii) 19 individuals diagnosed with CZS and microcephaly - based on imaging studies linked to the clinical presentation of the condition. All participants exhibited normal click-ABR tests. FFR waveforms were documented using the /da/ syllable employing the Navigator Pro. The statistical analysis used was ANOVA (p-value <0.05). Results: no distinctions were observed concerning the variables of group, age, or gender with respect to FFR latency values, except for an interaction between gender and group for latency values associated with waves V and F. Children with CZS and microcephaly showed a difference for latency values in wave V for both males and females, when compared to the control group. Conclusion: children presented with CZS and microcephaly showed higher average latencies for waves V, A, C, D and F (male) compared to the control group, whereas, in waves E, F (female) and O they showed higher values in the control group.

Temporal Ordering and Auditory Resolution in Individuals with Sensorineural Hearing Loss

Abstract Introduction Peripheral hearing loss, besides causing inadequate auditory input, can lead to distortions in the tonotopic auditory map and reorganization of neural networks. Therefore, the processing of temporal aspects of a sound stimulus and, consequently, the effectiveness of human communication can be negatively impacted. Objective To test the temporal ordering and auditory resolution of people with mild and moderate sensorineural hearing loss and to compare them with the those of people with normal hearing. Methods A total of 19 right-handed individuals aged 16 to 59 years with mild to moderate postlingually acquired symmetric bilateral sensorineural hearing loss participated in the study. They were submitted to frequency and duration pattern tests and a random gap detection test. Results The mean correct response rate in the frequency pattern test was of 66.3%, and, in the duration pattern test, 71.7%. The mean threshold in the random gap detection test was of 14.1 ms. A comparison with the criteria established for normal subjects without peripheral hearing loss revealed that more than half the subjects had abnormal results in the temporal ordering test, while a smaller fraction had reduced temporal resolution. Conclusions The performance of the subjects with acquired sensorineural hearing loss was poorer than that of the participants without peripheral hearing loss. Their results on the temporal ordering test were also poorer than in the temporal resolution test, demonstrating the importance of analyzing both these auditory skills in people with peripheral hearing loss.

The Effects of Monaural Stimulation on Frequency-Following Responses in Adults Who Can Sing in Tune and Those Who Cannot

Abstract Introduction Musicians have an advantage over non-musicians in detecting, perceiving, and processing nonverbal (i.e., environmental sounds, tones and others) and verbal sounds (i.e., consonant, vowel, phrases and others) as well as instrumental sounds. In contrast to the high skill of musicians, there is another group of people who are tone-deaf and have difficulty in distinguishing musical sounds or singing in tune. These sounds can originate in different ways, such as a musical instrument, orchestra, or the human voice. Objectives The objective of the present work is to study frequency-following responses (FFRs) in individuals who can sing in-tune and those who sing off-tune. Methods Electrophysiological responses were recorded in 37 individuals divided in two groups: (i) control group (CG) with professional musicians, and (ii) experimental group (EG) with non-musicians. Results There was homogeneity between the two groups regarding age and gender. The CG had more homogeneous responses in the latency of the FFRs waves when responses between the right and left ears were compared to those of the EG. Conclusions This study showed that monaural stimulation (right or left) in an FFR test is useful for demonstrating impairment of speech perception in individuals who sing off tune. The response of the left ear appears to present more subtlety and reliability when identifying the coding of speech sound in individuals who sing off tune.

Can an individual with low frequency hearing in the candidate ear benefit from a cochlear implant even if they have normal hearing in the other ear?

PURPOSE: To determine hearing preservation and subjective benefit after cochlear implant (CI) surgery in patients with low frequency hearing in the ear to be implanted (i.e., they have partial deafness, PD) and close to normal hearing in the other. METHODS: There were two study groups. The test group was made up of 12 adult patients (mean age 43.4 years; SD 13.6) with normal hearing or mild hearing loss in one ear, and with PD in the ear to be implanted. The reference group consisted of 12 adult patients (mean age 44.5 years; SD 14.1) who had PD in both ears and who underwent unilateral implantation in their worse ear. Hearing preservation was assessed 1 and 14 months after CI surgery using the Skarzynski Hearing Preservation Classification System. The APHAB questionnaire was used to evaluate the benefit from the CI. RESULTS: The differences in HP% between the groups were not significant: mean hearing preservation (HP%) in the test group was 82% one month after CI surgery and 75% some 14 months after implantation; corresponding results in the reference group were 71% and 69%. However, on the APHAB background noise subscale, the benefit in the test group was significantly larger than in the reference group. CONCLUSION: To a large extent it was possible to preserve low-frequency hearing in the implanted ear. This means that individuals with low frequency hearing in the implanted ear (partial deafness) and with normal hearing in the other generally received more benefits from cochlear implantation than did patients with partial deafness in both ears. We conclude that residual low frequency hearing in the ear to be implanted should not be considered a contraindication for a CI in a patient with single-sided deafness.

Audiometric and Self-Reported Outcomes in Patients with Otosclerosis and a Small Air-Bone Gap after Stapes Surgery.

INTRODUCTION: The main determinant in deciding on stapes surgery in patients with otosclerosis is the degree of hearing loss, specifically the size of the preoperative air-bone gap (ABG). The debate over the minimum ABG centers on the risk-to-benefit ratio of stapes surgery in patients with small ABG (sABG). The aim of this study was to measure the audiological outcomes and self-assessed satisfaction in a group of otosclerosis patients with an sABG who underwent stapedotomy. METHODS: There were 83 patients with preoperative sABG ≤25 dB HL (mean of 500, 1,000, 2,000, 4,000 Hz) included in this study. Audiometry was performed before surgery and 6 months and 12-36 months after surgery. Self-reported patient outcomes before and after surgery were collected using questionnaires. RESULTS: At the 6-month follow-up, the ABG was closed within 10 dB in 63 (78.8%) cases. Preoperatively, tinnitus was present in 70% of patients, of which 66% reported that tinnitus was a moderate or severe problem. Postoperatively, 71% of patients experienced a significant reduction in tinnitus severity and 34% of them reported complete disappearance. The self-report outcomes relating to quality of life and hearing reflected a good level of satisfaction in most patients. CONCLUSION: The possibility of reducing bothersome tinnitus after stapes surgery, and thus improving the patient's quality of life, should be taken into account when making a decision on stapes surgery in these patients.

New technology can benefit established middle ear implant users: Samba 2 vs previous models of audio processors for Vibrant Soundbridge.

INTRODUCTION: The Vibrant Soundbridge (VSB) is a semi-implantable hearing aid for patients with various types of hearing loss and has been available for over 25 years. Recently, new audio processors with advanced signal processing, noise reduction, and multi-microphone technology have appeared. The aim of this study is to compare the benefits of using the newest Samba 2 processor to the previous generation processors in a group of experienced VSB users. METHODS: There were 22 experienced VSB users (mean time of using VSB was 9 years, SD = 2) who had their processor (D404 or Amadé) upgraded to the newest model (Samba 2). The mean age of the subjects was 56 years (SD = 20). Assessments were made by free-field audiometry, speech reception in quiet and noise, and Patient-Reported Outcome Measures (PROMs). RESULTS: Hearing tests in free field showed statistically significant improvements in hearing sensitivity and speech discrimination in quiet and noise with the Samba 2 audio processor compared to the earlier technology. PROMs confirmed the benefits of using the newest audio processor and there was more satisfaction in terms of usability. CONCLUSIONS: Access to modern technology for VSB patients provides measurable benefits.

Auditory middle latency responses and hearing skills in adults / Potencial evocado auditivo de média latência e habilidades auditivas em adultos

ABSTRACT Purpose: to compare the Auditory Middle Latency Response in adults, one group with and another group without altered auditory skills. In addition, the aim was to compare cut-off values of 30% and 50% for the Ear Effect in terms of sensitivity and specificity. Methods: the sample comprised 32 individuals of both genders with no hearing loss who were divided into Group 1 (16 individuals with no alterations in auditory skills) and Group 2 (16 individuals with alterations in auditory skills). All participants received an audiological evaluation and measurement of Brainstem and Auditory Middle Latency Potentials. Results: when Group 1 and Group 2 were compared, a statistically significant difference was only observed in Na and Pa amplitude of waves A1C3 and A2C3. In the analysis of sensitivity and specificity of the Auditory Middle Latency Response, a cut-off value of 50% gave a better balance between sensitivity and specificity. Conclusion: adults presented with altered auditory abilities had smaller response amplitudes in the Na and Pa components of the waves generated in the left hemisphere. A cut-off value of 50% gave a better discrimination of the Ear Effect for identifying subjects with altered auditory skills.

RESUMO Objetivo: comparar a latência e a amplitude dos componentes Na, Pa, Nb e Pb do Potencial Evocado Auditivo de Média Latência em adultos com e sem alterações em habilidades auditivas, bem como analisar a sensibilidade e a especificidade dos valores de corte de 30% e 50% para o Efeito de Orelha. Métodos: compuseram a amostra 32 indivíduos de ambos os sexos e sem perda auditiva, sendo subdivididos em Grupo 1 (16 indivíduos sem alterações em habilidades auditivas) e Grupo 2 (16 indivíduos com alterações em habilidades auditivas). Todos os participantes foram submetidos a uma avaliação audiológica e aos Potenciais Evocados Auditivos de Tronco Encefálico de Média Latência. O teste ANOVA foi utilizado na análise dos dados, considerando significantes os valores de p menores ou iguais a 0,05. Resultados: foi observada diferença estatisticamente significante apenas na amplitude de Na e Pa, quando Grupo 1 e Grupo 2 foram comparados. Esta diferença foi observada nas ondas A1C3 e A2C3. Na análise de sensibilidade e especificidade do Potencial Evocado Auditivo de Média Latência, observou-se que o valor de corte de 50% apresentou um melhor equilíbrio entre os critérios de sensibilidade e especificidade. Conclusão: os indivíduos adultos com alterações nas habilidades auditivas apresentaram menor amplitude de resposta nos componentes Na e Pa das ondas geradas no hemisfério esquerdo. O valor de corte de 50% apresentou um melhor equilíbrio na análise do Efeito de Orelha para a contribuição no diagnóstico de alterações de habilidades auditivas.

Stapedotomy in Congenital Stapes Ankylosis with Mobile Footplate: A Case Report.

BACKGROUND This paper presents a case of a 15-year-old child with a rare congenital anomaly of the middle ear in which the stapes was fused to the medial wall of the tympanic cavity. CASE REPORT This defect coexisted with partial malleus fixation in the attic and caused conductive hearing loss at an average level of 35-40 dB. Two exploratory tympanotomies were performed, where excess bone between the stapes and promontory was removed and the head of the malleus was released in the attic. The good effect of these procedures was unstable, mainly due to re-attachment of the stapes to the medial wall of the tympanic cavity. At the next surgery it was decided to perform stapedotomy, despite the mobile stapes footplate. The operation was performed with a small-fenestra stapedotomy technique. Perforation of the footplate was done using a microdrill with a balanced speed. A KURZ prosthesis with a diameter of 0.5 mm was used. The postoperative period passed without any complications. Three and 6 months after the surgery, control pure tone audiometry was performed and showed significant improvement in hearing thresholds. During the follow-up period of more than 6 months, hearing improvement remained stable. CONCLUSIONS We concluded that it was safe to perform stapedotomy in the presence of a mobile stapes footplate when congenital anomaly of the stapes superstructure caused its severe fixation in the middle ear. In our opinion, in a child with congenital ear anomaly, consideration should be given to the multifocal origin of the hearing loss.

Rapid Maxillary Expansion (RME): An Otolaryngologic Perspective.

Background. To evaluate the possible effects of Rapid Maxillary Expansion (RME), such as nasal breathing problems, middle ear function, Obstructive Sleep Apnea (OSA) in the otolaryngology field. RME has already been introduced in orthodontics to expand the maxilla of young patients affected by transversal maxillary constriction. Methods. A literature search was performed using different databases (Medline/PubMed, EMBASE, and CINAHL), from May 2005 to November 2021, according to the PRISMA guidelines. Results. The application of RME in children has shown good results on nasal function, reducing nasal resistances, independently from a previous adenotonsillectomy. These results are not only related to the increasing of nasal transverse diameters and volume, but also to the stiffening of airway muscles, enabling the nasal filtrum function and avoiding mouth opening, thereby decreasing respiratory infections. Positive effects have also been reported for the treatment of conductive hearing loss and of OSA, with the reduction of Apnea Hypopnea Index (AHI), possibly due to (i) an increased pharyngeal dimensions, (ii) a new tongue posture, and (iii) reduced nasal respiratory problems. Conclusions. Otolaryngologists should be aware of the indications and benefits of the RME treatment, considering its possible multiple beneficial effects.

The Oticon Ponto System in Adults With Severe-to-Profound and Mixed Hearing Loss: Audiologic Outcomes and Patient Satisfaction.

OBJECTIVE: To measure audiologic outcomes and self-assessed satisfaction with the Ponto system in a group of patients who had severe to profound and mixed hearing loss. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Sixteen patients aged 21 to 74 years with severe-to-profound and mixed hearing loss (bone conduction thresholds, ≥45 dB HL). INTERVENTIONS: Ponto implant surgery. MAIN OUTCOME MEASURES: Pure-tone audiometry, free-field hearing thresholds, effective gain, word recognition score in quiet, and speech reception threshold (SRT) in noise were assessed. Patient-reported outcomes were collected using the Clinical Global Impression Scale, Glasgow Benefit Inventory, and Abbreviated Profile of Hearing Aid Benefit. Information concerning any medical complications was also gathered. RESULTS: Both word recognition score and SRT were significantly better after 12 months compared with before surgery. At normal speech level (65 dB SPL), 12 of 16 users had speech discrimination ≥70%. However, at the 12-month follow-up, the average effective gain was -6.2 dB. In general, the self-report outcomes showed good satisfaction in most patients. Postoperatively, skin complications were noted in six patients, of whom two underwent reoperation. All patients were still using the Ponto after an average observation time of 2.7 years. CONCLUSION: Although skin complications were not uncommon, the Ponto system seems to be an effective method of improving hearing performance and provides subjective satisfaction in real-life situations in patients with severe-to-profound and mixed hearing loss. However, considering the significantly increased bone conduction thresholds and the risk of their further deterioration, long-term follow-up is still needed.

Multi-Frequency Intraoperative Monitoring of Hearing Preservation during Cochlear Implantation.

(1) Background: Current indications for cochlear implants (CIs) have expanded to include patients with appreciable low-frequency hearing. However, longitudinal results indicate that only one-third of these recipients retain full hearing preservation. In another words, the remaining two-thirds lose this facility either partially or fully. This points to the need to better understand the impact of cochlear implantation on cochlear integrity. Intracochlear electrocochleography (ECochG) involves the recording of electrical potentials generated in the inner ear in response to acoustic stimuli, and previous studies have shown that these potentials give an indication of residual inner ear function. Aim of the research: The aim is to monitor intracochlear ECochG during CI surgery and gain a better understanding of how the implant impacted inner ear function. A newly developed SPL Chirp was used for stimulation. (2) Methods: Intracochlear ECochG signals were measured in a subject with residual preoperative low-frequency hearing, while an electrode array was introduced into the cochlea and was continued until the round window was sealed. Afterwards, surgical events were reviewed with the surgeon; preoperative and postoperative radiological data and hearing thresholds were also evaluated. (3) Conclusions: Real-time intraoperative monitoring, with multifrequency evaluation and video recording, has the potential to allow surgeons and audiologists to continuously assess cochlear function. ECochG monitoring may be a useful tool during cochlear implantation to gain frequency-specific information on the status of the patient's hearing, assisting surgeons to lower hearing trauma during the operation.

Chronic Tinnitus and the Positive Effects of Sound Treatment via a Smartphone App: Mixed-Design Study.

BACKGROUND: Tinnitus is a phantom auditory sensation in the absence of an external stimulus. It is accompanied by a broad range of negative emotional symptoms and a significantly lower quality of life. So far, there is no cure for tinnitus, although various treatment options have been tried. One of them is mobile technology employing dedicated apps based on sound therapy. The apps can be managed by the patient and tailored according to their needs. OBJECTIVE: The study aims to assess the effect of a mobile app that generates background sounds on the severity of tinnitus. METHODS: The study involved 68 adults who had chronic tinnitus. Participants were divided into a study group (44 patients) and a control group (24 patients). For 6 months those in the study group used a free mobile app that enriched the sound environment with a background sound. Participants were instructed to use the app for at least 30 minutes a day using their preferred sound. The participants in the control group did not use the app. Subjective changes in the day-to-day functioning of both groups were evaluated using the Tinnitus Handicap Inventory (THI) questionnaire, a visual analog scale, and a user survey. RESULTS: After 3 months of using the app, the THI global score significantly decreased (P<.001) in the study group, decreasing again at 6 months (P<.001). The largest improvements were observed in the emotional and catastrophic reactions subscales. A clinically important change in the THI was reported by 39% of the study group (17/44). Almost 90% of the study participants (39/44) chose environmental sounds to listen to, the most popular being rain and ocean waves. In the control group, tinnitus severity did not change over 3 or 6 months. CONCLUSIONS: Although the participants still experienced limitations caused by tinnitus, the advantage of the app was that it led to lower negative emotions and thus reduced overall tinnitus severity. It is worth considering whether a mobile app might be incorporated into the management of tinnitus in a professional setting.

The Clinical Effect of Steroid Therapy on Preserving Residual Hearing after Cochlear Implantation with the Advanced Bionics HiRes Ultra 3D Cochlear Implant System.

(1) Background: The main aim of this study was to assess the clinical effectiveness of two different schemes of administration of steroids ((1) dexamethasone administered intravenously in comparison with (2) combination of steroid treatments: orally administered prednisone and intravenously administered dexamethasone) in comparison with a control group (no steroid administration) on hearing preservation (HP) in patients who underwent an Advanced Bionics cochlear implantation. (2) Methods: Thirty-five adult patients met the inclusion criteria. All patients were randomly divided into three subgroups depending on the scheme of steroid administration: (1) the first subgroup with only intravenously administered dexamethasone (0.1 mg per kg body weight twice a day for three days), (2) the second subgroup with a combination of methods of administration of steroids (intravenous and oral steroid therapy (dexamethasone, 0.1 mg/kg body weight twice a day plus prednisone, 1 mg/kg weight once a day for three days before surgery and after administration of dexamethasone (4th, 5th, 6th day) and after this time the dose of prednisone was reduced)) and (3) the third subgroup without steroid therapy (control group). The results were measured by pure tone audiometry (PTA) in three periods: (1) before implantation, (2) during activation of the processor (one month after implantation), and (3) 12 months after activation. Patients' hearing thresholds before implantation were on average 82 dB HL, 77 dB HL, and 88 dB HL, respectively. (3) Results: The majority of the patients from the first subgroup had hearing preserved partially (77.8%). A similar result was observed in the second study group (oral + i.v.) (partial hearing preservation was found in 61.5% of the participants). The opposite was true in the control group; a plurality of control patients (38.5%) had no measurable hearing 12 months after the activation of the processor. (4) Conclusions: Pharmacological treatment consisting of the administration of steroids in patients who had undergone cochlear implantation with the Advanced Bionics HiRes Ultra 3D cochlear implant system may be beneficial for preserving residual hearing in patients.

The COVID-19 pandemic and upgrades of CI speech processors for children: part II-hearing outcomes.

PURPOSE: To gauge the benefits to children of upgrading speech processors during the COVID-19 pandemic. METHODS: The study involved 297 children, aged from 7.3 to 18.0 years, whose processors were upgraded to either Nucleus 7 or Kanso 2, or to Sonnet 2 or Rondo 3. To document the benefits of the upgrades, a speech-in-noise discrimination test and Patient Reported Outcome Measures (PROMs) were used. RESULTS: There was a significant benefit from the newer processors in terms of speech discrimination in noise. Patient Reported Outcome Measures (PROMs) indicated less hearing disability, a higher level of functioning in everyday life situations, and more satisfaction with the new speech processor in social situations. CONCLUSION: There is a measurable improvement in performance when the devices are upgraded to the new technology.

The COVID-19 pandemic and upgrades of CI speech processors for children: part I-procedure of speech processor upgrade.

PURPOSE: To demonstrate the feasibility of upgrading speech processors during the COVID-19 pandemic. METHODS: Adopting concepts from "lean thinking", we optimized hospital workflows to allow speech processors to be upgraded despite the obstacles arising from national guidelines for COVID-19 prevention. The study involved 297 children, aged from 7.3 to 18.0 years, whose processors were upgraded on five consecutive Saturdays during a time of peak COVID-19 in Poland. RESULTS: The optimized workflow allowed us to conduct speech processor upgrades during a time of peak COVID-19 in Poland. The upgrades were conducted as scheduled, patient flow was smooth, appropriate social distancing was kept, and no reports of COVID-19 infection in our patients in the 2 weeks after their visit were received. CONCLUSION: Upgrading of speech processors in children is still feasible under coronavirus conditions.

Validation of AQoL-8D: a health-related quality of life questionnaire for adult patients referred for otolaryngology.

PURPOSE: The purpose of the study was to validate the AQoL-8D questionnaire in the adult population of patients referred to an otolaryngology clinic. METHODS: AQoL-8D was translated into Polish. 463 patients (age18-80 years) with otolaryngological conditions were assessed with the AQoL-8D, SF-6D, and SWLS questionnaires. We investigated the item content-relevance, factor structure by means of Confirmatory Factor Analysis, corrected item-total correlations, Cronbach's alpha, Pearson correlation of the AQoL-8D scores with results from SF-6D and from the SWLS questionnaires. Finally, ANOVA was used to test the AQoL-8D ability to group the HRQoL of patients in terms of their otolaryngological management type. RESULTS: The median score of item content-relevance was 5.0 for all AQoL-8D items. Confirmatory Factor Analysis revealed the following fit indices: Comparative Fit Index = 0.81; Tucker-Lewis Index = 0.80; and Root Mean Square Error of Approximation = 0.07. Cronbach's alpha for AQoL-8D dimensions ranged from 0.48 to 0.79. Mean item-total correlations over all dimensions, super dimensions, and the instrument overall were higher than 0.3. There was a significant Pearson correlation between the results obtained with AQoL-8D and SF-6D (r = 0.68), and with AQoL-8D and SWLS (r = 0.43). A one-way ANOVA showed a significant effect of management type on HRQoL as measured by AQoL-8D [F(4,458) = 6.12, p < 0.001] CONCLUSION: AQoL-8D provides valid and reliable measures of HRQoL in patients undergoing otolaryngological treatment. Because it is a generic questionnaire, it is possible to make general comparisons of otolaryngology outcomes with those from other subspecialties.

Effectiveness of tinnitus therapy using a mobile application.

BACKGROUND: The World Health Organization reports that the number of tinnitus sufferers is increasing year on year. Given the common use of mobile devices and the availability of applications designed to support patients in tinnitus therapy and reduce tinnitus severity, patients seeking help are likely to try this form of support. The aim of this study was to evaluate the effectiveness of a mobile application in tinnitus sound therapy, in this case ReSound Tinnitus Relief™. METHODS: The study involved 52 patients hospitalized for tinnitus. All participants used the free ReSound Tinnitus Relief application for 6 months. The application is based on sound therapy. Patients were advised to use the application for at least 30 min per day, the sounds should not completely mask the tinnitus, and they should be listened to via a loudspeaker. The effects of the therapy were evaluated by means of standardized questionnaires for tinnitus severity: the Tinnitus Handicap Inventory and the Tinnitus Functional Index. RESULTS: The study showed a reduction in tinnitus severity as measured by both questionnaires. The general severity decreased after the first 3 months and again in the following 3 months of using the application. In both questionnaires the biggest changes were observed in the subscales of emotions. CONCLUSIONS: Results obtained here from standardized questionnaires indicate that the tested application may contribute to tinnitus reduction. However, it is advisable to conduct further research on the applicability of such technology in medical practice.

Self-help interventions chosen by subjects with chronic tinnitus - a retrospective study of clinical patients.

OBJECTIVE: Self-help (without specialist support) can play an important role in tinnitus therapy. The purpose of this study was to investigate what fraction of subjects with tinnitus use self-help, what techniques are most commonly used to reduce tinnitus severity, and what distinguishes patients that use self-help from others. DESIGN: retrospective, observational study. STUDY SAMPLE: Adult patients admitted to our hospital clinic (460 participants) aged 19-83 years and reporting chronic tinnitus. The survey concerned therapy attempts prior to the clinic visit as well as self-help techniques chosen freely by the patient to reduce tinnitus severity. RESULTS: Data showed that 40.9% of the respondents chose some action themselves to reduce their tinnitus severity. Among the reported self-help techniques, acoustic stimulation was the most popular. In addition, patients chose distraction attention, relaxation, meditation, yoga, and physical activity. The likelihood of undertaking self-help increases with better education and higher tinnitus severity. CONCLUSIONS: Knowledge about patients' preferences of forms of self-help may help the health practitioner suggest a more suitable form of therapy. Due to the great interest in using sound therapy in tinnitus, it would be worthwhile looking at new forms of this therapy, for example increasingly popular mobile applications.
