About This Presentation

Description : Check out this medical PowerPoint presentation titled "Overview of tinnitus" by Nina L. Shapiro, MD.

This medical PowerPoint presentation is about tinnitus, a condition in which an individual experiences a ringing, buzzing, or other sounds in their ears or head that are not caused by an external source. It affects approximately 15-20% of the population, and it can be a temporary or chronic condition.

Tinnitus can be subjective or objective. Subjective tinnitus is the most common form, and it is typically caused by damage to the inner ear, exposure to loud noises, or age-related hearing loss. Objective tinnitus is less common and is caused by physical abnormalities in the ear, such as blood vessel disorders, muscle spasms, or a tumor.

Symptoms of tinnitus can vary in intensity and frequency, and they may be constant or intermittent. They can be accompanied by hearing loss, dizziness, or ear pain. Tinnitus can have a significant impact on an individuals quality of life, leading to stress, anxiety, and depression.

There is no known cure for tinnitus, but there are several treatments available to manage the symptoms. These include cognitive behavioral therapy, sound therapy, and medication. Prevention is also important, and individuals can protect their hearing by wearing earplugs in loud environments and avoiding exposure to loud noises for prolonged periods.

What is tinnitus? Perception of sound but no external source Usually experienced as buzzing, hissing or ringing Not fully-formed sounds e.g. speech or music Not sound hallucinations experienced during bouts of mental illness Occurs in one or both ears, or arising within the head It can have a profound effect on the sufferer “… perceived severity of tinnitus correlates closer to psychological and general health factors, such as pain or insomnia, than to audiometrical parameters …” (Zoger et al, 2006) Langguth B, et al. (2013) Lancet Neurol.12:920-930; Zöger S et al. (2006) Psychosomatics. 47:282-288. 24-Jun-23 Slide 3

Sound features of tinnitus Sounds experienced in tinnitus can vary according to several criteria: Langguth B, et al. (2013) Lancet Neurol.12:920-930. 24-Jun-23 Slide 4

Evaluating tinnitus severity At the other extreme, some patients suffer so much that daily living is difficult and they are unable to work. Others suffer a level of impairment between these two levels. Tinnitus is highly variable. Some patients are able to cope with the noise and their lives continue as normal. Langguth B, et al. (2013) Lancet Neurol.12:920-930. 24-Jun-23 Slide 5

The burden of tinnitus SCALE OF PROBLEM IMPACT TINNITUS RISK FACTORS A GROWING PROBLEM Tinnitus affects 10%–15% of the general population worldwide This is an estimated 280 million people Tinnitus limits daily living in 1%–2% of people with tinnitus Hearing impairment Increasing age Gender (male) Exposure to noise Increasing size of the elderly population Frequency of noise exposure in work and leisure environments Geocze L, et al. (2013) Braz J Otorhinolaryngol.79:106-111; Langguth B, et al. (2013) Lancet Neurol.12:920-930; Roberts LE, et al. (2010) J Neurosci. 30:14972-14979. 24-Jun-23 Slide 6

Peripheral events lead to central neurological changes A range of peripheral events can lead to central neuronal changes that manifest as tinnitus Other factors can be involved in either the development or the persistence of tinnitus HEARING LOSS NOISE TRAUMA OTOTOXIC DRUGS AUDITORY NERVE ABNORMALITIES CENTRAL AUDITORY PATHWAY NEURONAL ABNORMALITIES TINNITUS ONSET TINNITUS PERSISTENCE Langguth B, et al.

Brain response to auditory deprivation Patients with tinnitus exhibit enhanced auditory sensitivity This is caused by hyperactivity of the auditory central nervous system Homeostatic pathways cause increased central ‘gain’ (i.e. sensitivity) in response to auditory deprivation to: Maintain central nervous system activity during low sensory input Ensure nerve activity is modulated to respond to changes in sensory input In patients with tinnitus and hearing loss, the tinnitus pitch and the hearing loss frequency spectrum are usually matched INCREASED SOUND SENSITIVITY Hebert S, et al.

Tinnitus is a balance of sensory input and spontaneous activity The decreased input from the cochlea, due to outer hair cell damage, results in readjustments in the central auditory system resulting in abnormal neural activity including hyperactivity, bursting discharges and increases in neural synchrony.

Tinnitus and hearing loss Most patients with tinnitus have some degree of hearing loss 75%–90% of patients with otosclerosis have tinnitus ABOUT 80% OF PATIENTS WITH IDIOPATHIC SENSORINEURAL HEARING LOSS HAVE TINNITUS “Hearing loss is a hidden disability and to have tinnitus is sort of like a double whammy” Family physician with moderate tinnitus, Canada Axelsson A, Ringdahl A (1989) Br J Audiol 23:53-62; Ayache D, et al (2003) Otol Neurotol 24:48-51; Nosrati-Zarenoe R et al (2007) Acta Otolaryngol 127:1168-1175; Sobrinho PG et al.

Tinnitus and distress: a vicious cycle Experiencing sound in the absence of an external stimulus can be emotionally upsetting This reaction can make the sounds appear worse This results in a vicious cycle of worsening tinnitus and increasing distress TINNITUS EMOTIONAL DISTRESS Schaette R.

Other psychological associations with tinnitus Tinnitus is associated with increased levels of psychological problems 24/90 (26.7%) versus 5/90 (5.6%) for age-matched controls without tinnitus HYPOCHONDRIA HYPERACUSIS COGNITIVE IMPAIRMENT TINNITUS ANXIETY DEPRESSION SLEEP PROBLEMS Andersson G, McKenna L.

Other tinnitus-associated problems SLEEP PROBLEMS COGNITIVE IMPAIRMENT HYPERACUSIS Sleep disturbance is common in patients with tinnitus In particular, the time taken to achieve sleep may be lengthened in tinnitus patients Insomnia and tinnitus-associated distress can work together in a worsening spiral to adversely affect psychological wellbeing Patients with tinnitus can exhibit depressive functioning and/or anxious vigilance Cognitive performance can be worse among tinnitus sufferers versus controls in the absence of depression and anxiety Hyperacusis is an oversensitivity to certain sound frequencies or volumes It is common among tinnitus sufferers and may be a consequence of tinnitus In an age-matched control study, 60% of tinnitus sufferers reported hyperacusis, compared to 20% of controls Hyperacusis is measureable in tinnitus ears with and without hearing loss Andersson G, McKenna L.

Tinnitus management options Currently, there is no cure for tinnitus, but management is possible HEARING AIDS DRUGS SOUND THERAPY TINNITUS EVIDENCE BASED TINNITUS MANAGEMENT APPROACHES e.g. TINNITUS RETRAINING THERAPY COUNSELLING COGNITIVE BEHAVIOURAL THERAPY Belli H, et al.

Hearing aids are central to tinnitus management Reports of the use of hearing aids in the management of tinnitus go back over 60 years Because hearing loss is often associated with tinnitus, at least partial restoration of hearing should help to reduce the central gain in auditory perception that is a feature of tinnitus A recent scoping review of studies of hearing aids in tinnitus revealed that 17/18 publications showed improvements in tinnitus symptoms by fitting hearing aids “The majority of studies reviewed support the use of hearing aids for tinnitus management. Clinicians should feel reassured that some evidence shows support for the use of hearing aids for treating tinnitus …” Shekhawat et al, 2013 Shekhawat GS, et al.

Drug options for tinnitus management No approved drugs (European Medicines Agency [EMA] or US Food and Drug Administration [FDA]) Some psychopharmacological agents may help reduce the severity of psychological issues associated with tinnitus, and some may also lessen tinnitus symptoms Belli H, et al.

The need for multidisciplinary care Tinnitus management should include hearing aids with appropriate frequency ranges together with psychological support and education This requires a multidisciplinary care team GP, ENT specialist, psychologist/psychiatrist and hearing-care professional As a leading supplier of hearing aids, Phonak can be another member of your team, helping your patient to have the optimal hearing aid for their situation 24-Jun-23 Slide 22
