Treatment of sensorineural hearing loss

The first step is to determine whether the hearing loss is truly sensorineural, rather than conductive (e.g., earwax impaction, otitis media, or eustachian tube dysfunction). Sudden hearing loss, like "an ear being turned off," requires treatment as an emergency until a diagnosis is confirmed, because the therapeutic window for effective treatment is limited. [1]

It is critical to document the onset of symptoms. For sudden sensorineural hearing loss, most recommendations pin treatment effectiveness to the first 14 days, while some "rescue therapy" options limit the effectiveness to up to one month from onset. The earlier treatment is started, the higher the chance of recovery. [2]

A rapid assessment of associated symptoms is necessary: severe dizziness, neurological symptoms (facial asymmetry, limb weakness, speech impairment), bilateral hearing loss, and recurrent episodes. These symptoms increase the likelihood of a "non-idiopathic" cause and alter the examination and treatment strategy. [3]

Even if the cause is unclear, if sudden sensorineural hearing loss is suspected, the priority is to conduct audiometry as quickly as possible and begin therapy if the diagnosis is confirmed. A delay of "a couple of weeks to observe" often means a lost chance for recovery. [4]

Table 1. When urgent help is needed

Situation	Why is this important?	What to do in the coming hours or days
Sudden hearing loss within hours or 1 day	There is a short therapeutic window	Urgent audiometry, start treatment according to the sudden form scheme
Hearing loss plus severe dizziness	The higher the risk of a serious cause, the worse the prognosis.	Urgent consultation with a specialist, clarifying diagnostics
Bilateral sudden hearing loss	There may be a systemic reason.	Urgently exclude systemic diseases and drug causes
New neurological symptoms	There may be a central cause	Urgent neurological assessment, imaging as indicated
Rapidly progressive hearing loss over weeks	Autoimmune and other causes are possible	Accelerated examination, early rehabilitation

[5]

Diagnostics that really impact treatment

Audiometry is a basic tool: it confirms the type of hearing loss, its severity, and frequency profile, and helps assess its progression. For sudden sensorineural hearing loss, audiometry is recommended as soon as possible, preferably within 14 days of symptom onset. [6]

Next, the question of excluding retrocochlear pathology (e.g., tumor causes) is addressed: in cases of confirmed sudden sensorineural hearing loss, recommendations support magnetic resonance imaging (MRI) as the primary method or alternative tests if MRI is unavailable. However, routine computed tomography (CT) of the head "just in case" is not recommended. [7]

Routine laboratory testing for sudden sensorineural hearing loss is usually unhelpful and not recommended. Testing should be targeted and ordered when the history and examination suggest a specific cause: for example, an autoimmune process, infection, or drug toxicity. [8]

It is important to simultaneously evaluate risk factors and other treatable causes, such as recent use of potentially ototoxic medications, occupational or household noise, cancer therapy, and systemic inflammatory diseases. For drug-induced hearing loss, the key principle is early detection, hearing monitoring, and, if possible, replacement or correction of therapy. [9]

Table 2. Most frequently needed tests and why

Method	What does it give?	When it is especially useful
Pure tone and speech audiometry	Confirms the neurosensory type, degree, speech intelligibility	Always, especially with sudden hearing loss
Tympanometry and ear examination	Cuts off conductive causes	If you feel congested, after an infection, or if you suspect a plug
Magnetic resonance imaging (MRI) as indicated	Rules out retrocochlear causes	Asymmetry, unilateral persistent decrease, suspicion of a tumor cause
Targeted tests	They are looking for a specific systemic cause	Bilateral hearing loss, systemic symptoms, recurrent episodes
Assessment of drug load	Finds ototoxic factors	Chemotherapy, aminoglycosides, high doses of certain drugs

Sudden sensorineural hearing loss: Treatment where timing is everything

If sudden sensorineural hearing loss is confirmed, the most accepted basic therapy is corticosteroids, administered for the first 14 days. The option can be systemic (oral) or local (intratympanic administration into the middle ear cavity); the choice depends on contraindications, the risk of side effects, and the availability of the procedure. [11]

If recovery is incomplete, intratympanic steroids are considered as "rescue" therapy for approximately 2-6 weeks from the onset of symptoms. This is important because many patients present late or do not respond to initial therapy, and local administration may offer an additional chance of improvement with a lower systemic burden. [12]

Hyperbaric oxygen therapy is considered an option only in combination with steroids: either in the first 14 days or as rescue therapy for up to 1 month. However, the evidence base is mixed: reviews and meta-analyses show potential benefit in some patients, but the quality of the studies and the applicability of the results vary, so the method is not considered mandatory. [13]

It is particularly important that current guidelines explicitly warn against "popular but ineffective" prescriptions for sudden onset: routinely prescribing antiviral drugs, thrombolytics, vasodilators, and so-called vasoactive agents is not recommended, as they lack the expected benefit, while carrying risks and costs. This is a fundamental difference between the evidence-based approach and many older approaches. [14]

Table 3. Sudden sensorineural hearing loss: a practical solution framework

Step	Recommended tactics	Time window
Confirm the diagnosis	Urgent audiometry	Preferably immediately, but no later than 14 days
Initial therapy	Corticosteroids systemically and/or intratympanically	Up to 14 days from start
If the recovery is incomplete	Intratympanic steroids as rescue therapy	2-6 weeks
Additional option	Hyperbaric oxygenation only with steroids	Up to 14 days or up to 1 month
What to avoid routinely	Antivirals, thrombolytics, vasodilators, vasoactive	Always, unless there is a separate indication

[15]

Chronic and progressive sensorineural hearing loss

In chronic sensorineural hearing loss, "hair cell restoration pills" are generally unavailable because these structures are not fully regenerated. Therefore, the goal of treatment is to slow progression where possible and compensate for hearing loss as much as possible through rehabilitation. [16]

Compensation begins with hearing aids and properly selected settings, as this is what most often improves speech understanding and quality of life. If aids are ineffective and the hearing loss is more severe, cochlear implantation is considered: it does not restore "normal hearing," but can provide useful sound perception and improve speech understanding after a period of adaptation and training. [17]

It is also important to treat the causes and factors that accelerate hearing loss: noise exposure, repeated acoustic trauma, and uncontrolled use of ototoxic medications. For drug-induced hearing loss, the primary contribution to prognosis is early detection of audiometric changes and adjustment of therapy in consultation with the treating physician who prescribed the potentially toxic medication. [18]

In some patients, sensorineural hearing loss is associated with immune mechanisms, and then the strategy may include anti-inflammatory treatment, but such cases require accurate diagnosis and monitoring by a specialist: regimens are highly dependent on the clinical scenario, and the evidence base for many “steroid-sparing” approaches remains limited and ambiguous. [19]

Table 4. What can be the “treatment of the cause” for sensorineural hearing loss?

Possible cause	The essence of the approach	Commentary on evidence
Drug-induced ototoxicity	Early hearing monitoring, dose adjustment, and therapy change if possible	Supported by risk management reviews
Immune-mediated form	Anti-inflammatory therapy as indicated, dynamic assessment of response	The approach is individual, the data is heterogeneous
Noise load	Source elimination, hearing protection, safe listening training	Prevention is key, the damage is often irreversible.
Age-related hearing loss	Early auditory rehabilitation, correction of communication strategies	The main effect is achieved through rehabilitation.
Persistent severe bilateral loss	Cochlear implantation plus auditory-verbal rehabilitation	Efficiency depends on selection and rehabilitation

[20]

Tinnitus, hyperacusis, dizziness: it's not just the ear that needs treatment

Tinnitus often accompanies sensorineural hearing loss and can be more distressing than the hearing loss itself. Current guidelines emphasize the need to assess the impact of tinnitus on sleep, anxiety, attention, and quality of life, and then choose a comprehensive approach rather than relying solely on "vascular IVs." [21]

When tinnitus and hearing loss are combined, auditory therapy is often helpful: improving the audibility of external sounds reduces the contrast of internal noise. Sound therapy and psychological approaches, including cognitive behavioral interventions, are also used to reduce distress and improve adaptation. [22]

There are few medications with proven efficacy specifically for chronic tinnitus, so guidelines generally do not support "vitamins, nutraceuticals, and supplements" as primary treatment. Much more important are properly designed treatment plans, patient education, sleep and anxiety management, and the selection of hearing aids. [23]

If dizziness develops, don't automatically attribute it to "poor circulation." A clinical assessment of vestibular symptoms is necessary, as treatment approaches vary: sometimes vestibular rehabilitation is sufficient, while other times it's necessary to rule out specific inner ear diseases or central causes. [24]

Table 5. Tinnitus in sensorineural hearing loss: what usually works best

Tool	What does it affect?	Who is it especially suitable for?
Selecting a hearing aid	Reduces the severity of tinnitus by masking it with external sounds and improving audibility	Tinnitus plus hearing loss
Sound therapy	Reduces noise contrast, helps with habituation	For persistent tinnitus and sleep problems
Cognitive behavioral methods	Reduces distress, anxiety, and improves sleep	With a significant impact on quality of life
Training and support	Reduces fear, increases symptom control	Almost everyone at the start
Medicines	Not the primary method for chronic tinnitus	Considered only for concomitant indications

[25]

Prevention and monitoring: how not to worsen what remains

The most effective prevention of sensorineural hearing loss in adults is noise control and the rational use of medications with potential ototoxicity. A large proportion of the causes of hearing loss in the population are preventable, as highlighted by international reviews on hearing and rehabilitation. [26]

If potentially ototoxic drugs are prescribed, prevention strategies include identifying at-risk patients, performing a baseline hearing assessment before treatment, regular monitoring, and revising the treatment regimen at the first sign of deterioration. This is especially important in oncology and severe infections, where the cost of complications is high. [27]

After an episode of sudden sensorineural hearing loss, it's important not to "close the door" on the initial improvement. Recommendations recommend follow-up audiometry at the end of treatment and a repeat assessment within 6 months to document the outcome and initiate auditory rehabilitation promptly. [28]

To prevent social decline in quality of life, early integration of hearing technologies and communication strategies is important: subtitling, environmental adjustments, and training for loved ones. Rehabilitation is not a "last step," but rather a part of treatment that should begin early, as soon as it becomes clear that hearing will not be fully restored. [29]
