A study out of the US with 51 patients compared three different groups; placebo and intratympanic dexamethasone, oral prednisone and intratympanic saline and oral prednisone and intratympanic dexamethasone. There was a statistically significant improvement in the combined group vs either of the other groups. Of note this study used a placebo for systemic therapy and intratympanic saline in the control groups.
The study concluded that combined therapy was superior to intratympanic or oral steroids alone. A study of patients in the United States with ISSHL compared oral prednisone alone to four intratympanic injections of methylprednisolone alone for initial treatment. Following treatment the pure tone average improved This was found to be statistically equivalent.
This study concluded that intratympanic steroid treatment is not inferior to oral steroid treatment. In subgroup analysis, the authors noted a trend for better recovery with oral steroids in those with a pretreatment pure tone average of at least 90 dB and those who presented with dizziness. In addition to initial therapy in ISSHL, intratympanic steroid injections are also being used in salvage or secondary therapy after failure of initial therapy with systemic steroids.
A study from China studied 65 patients who had been admitted for treatment of ISSHL and treated with IV prednisolone who showed no improvement in hearing. The authors recommended intratympanic steroid therapy for those who failed systemic steroid treatment for ISSHL. Another placebo controlled, blinded study compared intratympanic dexamethasone to intratympanic saline injections in patients who failed systemic steroid therapy.
The authors again recommended the use of intratympanic steroids after failure of systemic steroid therapy. A Korean study compared the use of intratympanic dexamethasone to no further treatment in patients with ISSHL who failed systemic steroid treatment. The authors recommended use of intratympanic steroids following failure of systemic steroids.
A single study was found that compared the use of additional systemic steroids to the systemic steroids with intratympanic methylprednisolone in patients that failed initial systemic therapy. Poor prognosis was defined as hearing loss greater than 70 dB, age older than 60, a flat or high high frequency hearing loss on audiogram, presence of severe vertigo or time exceeding 2 weeks from onset of initial treatment.
The studies described here seem to suggest that intratympanic steroid injections alone or systemic steroid therapy alone are equally effective in the treatment of ISSHL. However, in certain communities, patients may not have access to an ENT who performs intratympanic injections and patients need to be able to see this specialist as soon as possible and 3—5 times over a two week period for injections.
Although monotherapy with either systemic or intratympanic steroids appears to be equally effective, the literature described above suggests that primary combined therapy is superior to monotherapy. It is important for these physicians to know that patients who fail to respond to initial oral steroids may still benefit from intratympanic steroids.
Most protocols in the literature initiated intratympanic injections immediately after failure of oral steroids. Physicians should promptly refer patients to an ENT comfortable performing transtympanic steroid injections. Optimal delivery of transtympanic steroids and absorption into the cochlea is an active area of research. A study from Taiwan advocated the use of a MicroWick placed through the tympanic membrane and had patients place a dexamethasone solution in the external auditory canal twice a day 27 in an attempt to provide continual cochlear absorption of the steroid.
Other companies are investigating ways to inject steroid into the middle ear that resorb much slower than the aqueous solutions currently being used, so that only one injection is needed. There are multiple questions regarding intratympanic steroid treatment for ISSHL that remain unanswered.
First, there is no universally accepted protocol for the use of intratympanic steroids. In the articles reviewed, the number of injections varied from 3 to 8 performed over a 1 to 4 week period; dexamethasone was most commonly used followed by methylprednisolone. Future studies determining the ideal steroid and the number and frequency of injections are needed.
It is also unclear why some patients benefit from intratympanic steroids while others do not. Likely, only certain underlying pathologies are amenable to steroid therapy. Perhaps the biggest hurdle in treatment of ISSHL with intratympanic steroids is recognizing the diagnosis and achieving timely access to care. A sudden drop in hearing in one ear is often incorrectly ascribed to fluid behind the ear drum or otitis media, and treated with decongestants or oral steroids.
In the absence of a formal audiogram, a Weber tuning fork test can be used to ascertain if a hearing loss is conductive or sensorineural. The test is performed by holding a tuning fork ideally Hz firmly against the forehead. Patients with a conductive hearing loss from otitis media or similar will hear the tuning fork louder in the affected ear, while patients with ISSHL will hear it better in the non affected normal ear.
If a tuning fork is not available, a mobile phone or pager turned to its vibrate function and pressed against the forehead will work quite well. It is distinctly clear that rapid initiation of therapy for ISSHL profoundly increases the chance for a good outcome. In the primary treatment of ISSHL, achieving the correct diagnosis rapidly is paramount, as early initial treatment greatly increases the chance of hearing recovery.
Both intratympanic steroids or systemic steroids alone appear equally effective, however the use of both intratympanic and systemic steroids together is likely superior to either used alone. Hyperbaric oxygen treatment may play a role in ISSHL treatment, although robust data is lacking and patient access to hyperbaric oxygen therapy is limited.

Abstract Idiopathic sudden sensorineural hearing loss ISSHL is the sudden loss of unilateral hearing of unknown etiology. Introduction A sudden decrease in sensorineural hearing from an unknown etiology broadly defines idiopathic sudden sensorineural hearing loss ISSHL. Open in a separate window. Figure 1. Figure 2. Conclusion In the primary treatment of ISSHL, achieving the correct diagnosis rapidly is paramount, as early initial treatment greatly increases the chance of hearing recovery.

These are sometimes called transtympanic steroid injections. We use steroid injections into the ear to treat several inner ear conditions such as:.
We may schedule a hearing test for you before the procedure in the Audiology Department. You can eat normally before and after the procedure. There are no restrictions. The procedure is performed by a head and neck surgeon in the office. It takes around 30 minutes. You may have symptoms after your procedure for a short time. These include:. The small amount of steroid injected is unlikely to cause side effects.
Occasionally a scar or small hole tympanic membrane perforation can form in the eardrum at the site of injection. In very rare cases the hole will need to be repaired surgically. If you have an emergency medical condition, call or go to the nearest hospital.
An emergency medical condition is any of the following: 1 a medical condition that manifests itself by acute symptoms of sufficient severity including severe pain such that you could reasonably expect the absence of immediate medical attention to result in serious jeopardy to your health or body functions or organs; 2 active labor when there isn't enough time for safe transfer to a Plan hospital or designated hospital before delivery, or if transfer poses a threat to your or your unborn child's health and safety, or 3 a mental disorder that manifests itself by acute symptoms of sufficient severity such that either you are an immediate danger to yourself or others, or you are not immediately able to provide for, or use, food, shelter, or clothing, due to the mental disorder.

In this disorder, there is excess buildup of normally occurring fluid in the inner ear. The buildup waxes and wanes. When severe, patients experience hearing loss, vertigo, tinnitus, and pressure in their ear. There is damage to the hearing and balance cells of the inner ear with each attack. Corticosteroids are strong anti-inflammatory medications that can be given to reduce the damage to these cells and treat hearing loss or vertigo.
Gentamicin is an antibiotic that is toxic to the balance cells. It may be given to provide relief from vertigo. Sudden hearing loss can also be treated by corticosteroids. If there is no improvement in hearing after taking steroid tablets, medication can be given by intratympanic injection.
In diabetics or certain stages of pregnancy, steroid tablets may have increased harmful effects. These effects are avoided by giving steroids through the ear drum. Other medications such as neuromodulators are being studied for conditions such as tinnitus.
They are not routinely given but are used in experimental trials. The injection is given in the clinic. Your doctor will lay you back and turn your head so that the affected ear is up. The ear drum is visualized with a microscope and a drop of numbing medication is placed on the ear drum. A thin needle is then used to make a tiny hole in the ear drum and medication is given through the needle. Fullness, pressure, or mild discomfort may be experienced as the ear is filled with medication.
You will then be asked to lay quietly without speaking or swallowing while the medication is absorbed by your inner ear. After an injection, residual fluid in the middle ear may cause temporary pressure, fullness, discomfort or dizziness. A dose of Tylenol will provide relief.
The ear drum will heal within a few days to weeks. It is generally well-tolerated, has been shown to result in superior perilymph concentration of steroids without the risk of systemic side effects, and so can be used as an alternative or in addition to systemic steroid use. Idiopathic sudden sensorineural hearing loss ISSNHL , considered an otological emergency, is defined as deafness of cochlear or retrocochlear origin within 72 hours, affecting at least 3 consecutive frequencies by 30 dB or greater with no identifiable cause.
Global incidence has been estimated to be 5 to 20 per , persons per year. This can comprise oral steroids, intratympanic steroid injections ITSI , or a combination of both. Guidelines from the American Academy of Otolaryngology-Head and Neck in advise that clinicians offer patients intratympanic steroid salvage therapy where there is incomplete recovery from sudden sensorineural hearing loss SSHL 2 to 6 weeks after onset of symptoms.
