Long-term improvement in tinnitus after modified tinnitus retraining therapy enhanced by a variety of psychological approaches.

This work evaluates an enhanced tinnitus retraining therapy (TRT) for patients with chronic tinnitus based on different group therapeutic interventions in a day hospital setting. Therapy for chronic tinnitus is intended to improve the way patients cope with tinnitus by learning how to reduce tinnitus-induced impairments. Short-term and long-term changes in stress variables and tinnitus-related distress were investigated using 3 psychometric instruments. Patients received 7 consecutive days of a multidisciplinary therapy at the Charité University Hospital in Berlin. The data were assessed before and after therapy, either immediately or after 3, 6 or 12 months. As a control, we used scores of tinnitus patients from the waiting list, and compared these to the scores of the therapy group 3 months after the end of treatment. The main factors of the modified TRT were Jacobson’s progressive muscle relaxation, physiotherapy, education via lectures and training of selective attention, as well as changes of appraisal, mental attitude and behavior towards tinnitus. The therapy resulted in a significant reduction in both short-term and long-term tinnitus-related distress and psychometric stress variables, with the latter being more reduced in patients with higher initial scores. Moreover, our study revealed differences in psychometric parameters concerning duration of tinnitus, age and gender, which may explain the different outcomes of therapy. The outpatient setting enables the patients to test, practice and transfer strategies into their everyday life.

Outcomes of long-term outpatient tinnitus-coping therapy: psychometric changes and value of tinnitus-control instruments.

Objectives: Increasing tinnitus compliance and coping are desirable aims of successful treatment in chronic tinnitus. However, application of established procedures such as tinnitus retraining therapy (TRT) is often relatively short. In addition, the value of tinnitus control instruments (TCI) is questionable, especially for minor severity levels of tinnitus, and the comparability of treatment results is low. To evaluate long-term changes of tinnitus-related distress, defined psychometric data were collected in patients with compensated tinnitus (cT) or decompensated tinnitus (dT) during a standardized 2-yr outpatient tinnitus-coping therapy (TCT). Design: In a prospective clinical investigation, the data of 70 tinnitus patients were recorded at the beginning and at 6-mo intervals, with a final investigation after 24 mo. The first group consisted of 40 patients with cT and dT who were randomly assigned to a treatment group and a waiting-list control group. After a period of 12 mo without treatment, the control group was treated similarly. The tinnitus questionnaire (TQ) of Goebel and Hiller, visual analog scales (VAS), and a severity questionnaire for tinnitus-associated complaints were used as psychodiagnostic instruments. Therapy components consisted of counseling, fitting patients with TCIs (TCI provision), auditory and relaxation training, and psychosomatic care if necessary. A second group of 30 patients with cT receiving TCT without TCI devices was investigated to evaluate the additive efficacy of TCI in cT. Results: The initial TQ score did not differ between the treatment group and the waiting-list control group. After 12 mo, the control group did not show any significant changes, but the treatment group had improved significantly. During TCT, the combined data of both groups showed a statistically significant decrease of the TQ score in dT (59.1 to 34.8) and cT (32.8 to 24.0). These changes were especially reflected by the subscales of cognitive and emotional distress and also by the VAS and the severity questionnaire. dT patients benefitted without dependence on age or duration of pre-existing tinnitus; for cT patients, this was true mainly of the younger and older subjects and for tinnitus lasting for less than 1 yr. TCI provision improved the efficacy of TCT in patients with cT. Conclusions: The psychometric changes demonstrate a clear decrease of tinnitus-related distress in all severity levels of sufficiently treated chronic tinnitus. Long-term TCT induces improvement even up to the time of 24 mo. With TCIs established particularly in patients with dT, our results suggest that a supporting adjustment of TCI devices is helpful in cT to foster quicker rehabilitation. The outpatient interdisciplinary TCT, consisting of cognitive tinnitus desensitization, TCI provision, and psychosomatic support if required, represents a successful treatment strategy for both dT and cT patients.

A Modified Version of Tinnitus Retraining Therapy: Observing Long-Term Outcome and Predictors

Tinnitusretraining therapy (TRT) in Germany includes not only directive counseling and sound therapy but also stress management and facultative psychotherapeutic treatment. The aim of the present study was to investigate the impact of this modified version of TRT on certain tinnitus-related aspects of distress and variables that may predict treatment outcome. Clinical data from 92 patients undergoing outpatient TRT in the Charité Tinnitus Centre were evaluated retrospectively over 1 year. Treatment outcome was defined by changes in specific areas of tinnitus-related distress and assessed by the Tinnitus Questionnaire. Changes in audiometric frequency and loudness of tinnitus were examined by regular audiometric testing. The overall Tinnitus Questionnaire score was significantly reduced after 1 year. Severely affected tinnitus sufferers (decompensated tinnitus) profited more than less affected patients (compensated tinnitus). In cases of indicated psychotherapy, improvement was significant for the patients who took advantage of psychotherapeutic treatment during TRT but was not significant for those who interrupted or dismissed an indicated psychotherapy. Changes in tinnitus-specific areas of distress were most pronounced in the scales for emotional and cognitive distress and intrusiveness. Significant changes in sleep disturbances, auditory perceptual difficulties and somatic complaints were observed in patients with decompensated tinnitus. In patients with chronic tinnitus, modified TRT may lead to significant subjective improvement in certain tinnitus-related symptoms like emotional and cognitive distress and intrusiveness. Particularly patients suffering from severe tinnitus distress take advantage of therapy. Careful psychotherapeutic diagnostics and therapies and, if necessary, motivation to make use of psychotherapy seem to be essential preconditions for therapeutic success in patients with severe psychosomatic comorbidity.

Gender and chronic tinnitus: differences in tinnitus-related distress depend on age and duration of tinnitus.

Objective: Conflicting data about the role of gender in tinnitus distress exist in the literature. In addition, little is known about gender differences regarding age and duration of tinnitus. Tinnitus was shown to be related to stress and impairment of coping, sense of coherence, and personal resources. There are known differences in the aforementioned psychological parameters between man and women or among different age groups. The authors hypothesized that this may also be true for patients with chronic tinnitus in addition to gender- and age-related differences in tinnitus annoyance. Therefore, using a large number of patients with chronic tinnitus, the authors analyzed pretherapeutic scores of tinnitus annoyance, perceived stress, proactive coping strategies, sense of coherence, and personal resources in addition to hearing loss and tinnitus pitch and loudness in respect to gender and age of the patients as well as duration of tinnitus. Design: The study group included 607 female and 573 male patients who reported tinnitus for longer than 3 months. The age of the patients ranged from 17 to 81 years in both gender groups. Pretherapeutic scores of tinnitus annoyance, perceived stress, proactive coping strategies, sense of coherence, and personal resources as well as the degree of hearing loss and tinnitus pitch and loudness were analyzed. Results: Irrespective of age and tinnitus duration, women were more annoyed by tinnitus and perceived more stress than men did. In addition, women scored lower than men in proactive coping, sense of coherence, and personal resources but had lower levels of hearing loss and tinnitus loudness than men did. The differences were small, but statistically significant. Analysis of three age groups revealed significant differences between older female and male patients. Tinnitus annoyance was stronger in the middle-age groups of women and men (45–59 years of age) than in younger patients and decreased again in older men (≥60 years of age), but not in older women. Women, but not men, had cognitive distress scores that progressed with age. Older women (≥60 years of age) reported more sleep disturbances than older men. Women had more somatic complaints and coped less efficiently than men, except for younger patients (<45 years of age). The scores of perceived stress decreased whereas scores of sense of coherence and self-efficacy increased in older men and women (≥60 years of age). However, women scored worse than men did in this age group. Hearing loss was found to be correlated with tinnitus loudness and age in both gender groups. The duration of tinnitus affected subjective hearing problems, intrusiveness of tinnitus, and proactive coping. This association was in part age-dependent. Conclusions: The authors found gender differences regarding tinnitus-related distress in patients with chronic tinnitus; however, these differences depended on age and in part on duration of tinnitus. Addressing these differences could result in improved, tailored therapy approaches. For instance, applying physical exercise and relaxation techniques could be of special help for older women to reduce their somatic complaints and sleep disturbances. Similarly, cognitive behavioral therapy could reduce their cognitive distress. Therapy for younger patients should in particular include stress management.

Biochemical differences between perilymph, cerebrospinal fluid and blood plasma in the guinea pig

Seven selected biochemical substances were systematically analyzed in perilymph (PL), cerebrospinal fluid (CSF) and blood plasma or serum of anesthetized guinea pigs in order to compare the composition of these fluids with regard to the origin and biochemical nature of PL. Compositional differences between the fluids were expressed by PL/CSF and PL/plasma concentration ratios of the chemical components measured. Contrary to the prevailing notion, the results suggest that the specific biochemical composition of PL corresponds neither to that of CSF nor to that of a simple ultrafiltrate of blood plasma. Furthermore, except for the total protein concentration, no significant differences were found in the composition of PL between the scala tympani and scala vestibuli.

Therapeutic Efficacy of Magnesium in Acoustic Trauma in the Guinea Pig

Comparative functional and morphological tests were performed in two groups of impulse noise-exposed guinea pigs treated either with magnesium (Mg) or isotonic saline as a placebo to extend the knowledge on the therapeutic efficacy of Mg in acoustic trauma demonstrated recently. The permanent threshold shifts were significantly lower in the Mg than in the placebo group as measured by auditory brainstem response audiometry, distortion product otoacoustic emissions and compound action potentials (CAPs) 1 week after exposure. This also applies to the damage to hair cell stereocilia tested with scanning electron microscopy. There were frequency-related differences in the individual functional responses. The CAP threshold shifts reflected the morphological damage most obviously.

Extra benefit of a second cochlear implant with respect to health-related quality of life and tinnitus.

Objective To evaluate whether the second cochlear implant (CI) provides any extra benefit with respect to health-related quality of life, tinnitus, and auditory abilities. Design The data were evaluated using validated questionnaires before and after the first and second CI supply. Preimplantation data were collected retrospectively. Patients Forty postlingually deafened adults, 11 male and 29 female subjects were included in this study. All patients were sequentially bilaterally implanted with a multi-channel CI for at least 6 months. Results The health-related quality of life assessed with the Nijmegen Cochlear Implant Questionnaire further increased after the second CI. In patients with initially higher level of tinnitus annoyance measured with the Tinnitus Questionnaire, the scores decreased after the first CI and remained steady after the second CI. Patients with initially lower level of tinnitus annoyance had a further decrease of the Tinnitus Questionnaire score after the second CI. Additionally, the second CI induced further improvement of auditory abilities, as assessed by the Oldenburg Inventory and the Freiburg monosyllable test in quiet and the HSM and Oldenburg sentence tests in noise. The quality of life scores correlated with the auditory abilities, especially after the second CI. Conclusion The present study provides evidence that the second CI leads to further increase in quality of life and reduction of tinnitus annoyance in addition to improvement of auditory abilities as compared with the first CI. Patients with bilateral CIs benefit from additional positive effects in all these fields.

Impact of laser eustachian tuboplasty on middle ear ventilation, hearing, and tinnitus in chronic tube dysfunction.

Objectives: Long-term Eustachian tube dysfunction (ETD) predisposes to various secondary middle ear diseases. Most surgical and prosthetical interventions on the Eustachian tube itself have proven to be ineffective, whereas middle ear surgeries treat the sequelae of ETD without major influence on the underlying tubal pathology. The purpose of our study was to evaluate the outcome of laser Eustachian tuboplasty (LETP) on tubal function and associated otological symptoms in topically anesthetized ETD patients with intact or perforated eardrums. Design: In a prospective clinical investigation, outpatient LETP was carried out in 31 subjects with therapy-refractory chronic ETD. The study population comprised two groups: 16 patients with mesotympanic eardrum perforations diagnosed with noninflammatory chronic otitis media (COM) and 15 patients with intact eardrums including otitis media with effusion, adhesion processes, and dysfunctional pressure equalization. Clinical examination and data acquisition were performed 2 wks before LETP as well as 8 wks and 1 yr postoperatively. On COM patients, LETP was done at 10-wk intervals before the scheduled tympanoplasty. Assessment of clinical effectiveness was based on transnasal videoendoscopy, ear microscopy, tubal function tests (Valsalva maneuver and passive tubal opening), audio- and tympanometric measurements, and visual analog scales. Tansnasal, fiber-guided laser surgery was performed in contact mode using a semiconductor diode laser (&lgr; = 830 nm, 4 W). We hypothesized that regulated laser ablation of hyperplastic mucosa at the epipharyngeal dorsal circumference of the tubal ostium could be effective in improving the associated symptoms such as dysfunctional pressure equalization, aural fullness, conductive hearing loss, and tinnitus. Results: LETP resulted in persistent volume reduction of the posterior tubal circumference in all patients. Objective parameters revealed significant improvement of tubal function tests and middle ear ventilation in 62% of subjects after 8 wks (66% after 1 yr). Significant long-term reduction of conductive hearing loss was achieved in both patient groups. Besides, tinnitus loudness was significantly reduced in COM subjects after tympanoplasty. Visual analog scales showed very low values for intraoperative pain and discomfort and high scores for long-term overall patient satisfaction as well as improvement of the symptoms such as dysfunctional pressure equalization and aural fullness. Subjects with post-LETP Valsalva feasibility marked higher values for satisfaction and symptom improvement than patients without successful Valsalva maneuver. COM subjects scored higher in hearing improvement and satisfaction after LETP and successful tympanoplasty than patients with intact eardrums. Conclusions: Outpatient LETP seems to be a suitable, safe, easily applicable, and well-tolerated treatment option before (revision) tympanoplasties and in all investigated diseases developing from long-lasting pathologic middle ear ventilation. Minimally invasive shaping of the hyperplastic nasopharyngeal Eustachian tube under topical anesthesia seems to be effective in improving tubal function as well as the associated symptoms such as dysfunctional pressure equalization, aural fullness, and conductive hearing loss in otherwise therapy-refractory chronic ETD.

Three years later: report on the state of well-being of patients with chronic tinnitus who underwent modified tinnitus retraining therapy.

Successful management of patients with chronic tinnitus is an important health issue. One of the tinnitus management strategies used at our Tinnitus Center is a combination of tinnitus retraining therapy (TRT) with physiotherapy and psychological management [called modified TRT (MTRT)]. We have used this type of management for over a decade and have described the protocol in detail elsewhere. In the present study, we wanted to determine the effect of MTRT on the well-being of tinnitus patients 3 years after treatment onset. One hundred and thirty patients with chronic tinnitus were assessed using psychometric instruments immediately before 7-day MTRT, immediately after the therapy and 3 years later. Patients with very severe tinnitus-related distress associated with major depression and a risk of suicide were excluded from this study. MTRT resulted in a sustained reduction of tinnitus-related distress. Moreover, the quality of life of patients had increased, as assessed by a separate questionnaire. The effect of MTRT was influenced by the degree of tinnitus-related distress and by the patients age, the latter being gender dependent. Hearing loss and tinnitus duration had only a minor influence on the therapeutic effect. Taken together, we report a positive change in the state of well-being of patients with chronic tinnitus measurable with various psychometric instruments 3 years after the onset of MTRT. i 2014 S.

Protective effects of magnesium on noise‐induced hearing loss: Animal studies

Magnesium (Mg) deficiency was found to increase noise‐induced hearing loss in laboratory animals. This paper reports both prophylactic and therapeutic effects of Mg on the acoustic trauma produced by a high‐level impulse noise series (Lpeak 167 dB, 38 min, 1/s). Hearing loss was tested by auditory brainstem response audiometry at frequencies between 0.5 and 32 kHz. Permanent hearing threshold shifts (PTS) were measured 1 week after the exposure. For the prophylaxis experiments, anesthetized guinea pigs with either a physiologically high or low Mg status, produced by different diets, were used. For the therapy experiments, animals with the low Mg status received (immediately after exposure) either Mg injections combined with a Mg‐rich diet or saline as a placebo. Total Mg concentrations of perilymph, cerebrospinal fluid, and plasma were analyzed to test the Mg status of the animals. The PTS was found to be significantly lower in the high‐Mg group than in the low‐Mg group. This also applies to the PTS found...
