The steroid medication is then gently injected into the middle ear through a fine needle. This can cause a feeling of fullness within the ear and a reduction of hearing whilst the ear fills with the steroid medication, but this is usually short-lived. Once the procedure is over, the operating table is usually tilted in a head-down position as this encourages the steroid medication to remain within the middle ear and not to leak out too soon.
You will be taken back to the recovery area and subsequently the ward where basic observations will be taken. You will be allowed to eat and drink something, and when you are feeling better you can go home. It is not unusual to experience feelings of ear fullness, tinnitus or even dizziness after the procedure, although these should settle quickly.
It is not particularly painful. It is quite common for several injections to be required. This is because the effect of steroids is cumulative, in other words their maximum benefit is seen after multiple treatments. Usually a course of three to four injections is administered, separated a month apart, although this may vary according to your own particular condition.
The procedure is generally extremely safe. Steroids do not have any significant side effects when used in such small doses to a specific local area. One possible risk is of a perforation of the ear drum after repeated injections, although this is not usually a major problem as the hole is usually tiny and easily repaired.
Likewise, some scarring of the eardrum may occur but this rarely causes any symptoms. It is possible that the vertigo may not get any better. There is a very remote chance that it could get worse if the steroid is injected into the wrong part of the ear, although this is highly unlikely to happen. In some instances, your specialist may recommend that you undergo an injection of gentamicin into the middle ear instead of a steroid.
Gentamicin is an antibiotic which is known to have mildly toxic effects on both the balance and hearing parts of the ear, although its toxic effects on the vestibular system are very much more potent than on the hearing. Despite this, there is an increased chance of a hearing loss occurring with intratympanic gentamicin injections. For this reason, they are usually reserved for patients with a pre-existing severe hearing loss at the time the vertigo is diagnosed.
The importance of early IT injection of steroids and its significant influence of hearing recovery had been reported by many researchers [ 39 , 40 ]. This was consistent with our results that showed that early IT injection was associated with a better prognosis,. Severe loss of hearing has been shown in several studies to have poorer recovery rates [ 18 , 40 , 41 ].
Good hearing outcomes following IT injection of dexamethasone for the management of ISSNHL was statistically associated with early intervention and less degree of pretreatment hearing loss.

Results Our study was conducted on 30 adult patients with unilateral ISSNHL who failed to respond or with contraindications to systemic steroids.
Background Sudden sensorineural hearing loss SSNHL is one of the most serious otologic emergencies that may have a deleterious and permanent effect of quality of life [ 1 ].
Another study combining oral and IT corticosteroids did not show a difference in hearing recovery compared with corticosteroids alone . A recent study proposed IT treatment as the sole initial treatment . Their protocol consisted of early injections for 3 consecutive days, with only 3 of 34 patients failing to improve. A systematic review concluded that IT steroids can be a valuable solution for patients with ISSNHL who either cannot tolerate systemic steroid therapy or are refractory to it .
For patients with diabetes who cannot take systemic corticosteroids, IT steroids may be an alternative [19,20]. Intratympanic steroids are usually administered as either dexamethasone or solumedrol methyl prednisolone . Agents such as histamine and hyaluronic acid have been shown to facilitate transport of the corticosteroid across the round window membrane in laboratory studies [22,23]. Intratympanic corticosteroids appear to affect both immune suppression and ion homeostasis .
Higher concentrations appear to have better outcomes. The frequency of IT steroid administration also varies widely between studies, from self-administration by the patient across a pressure-equalizing tube PET several times per day to physician administered for several consecutive days to once weekly or less.
Moreover, IT corticosteroids have been reported as primary, secondary, or salvage treatment. Although with less potential toxicity than systemic corticosteroid treatment, IT corticosteroids can also have adverse effects. These are infrequent but include pain, transient dizziness, infection, persistent tympanic membrane perforation, and possible vasovagal or syncopal episode during injection, cost, and multiple office visits.
The steroids are delivered to the middle ear and then absorbed and diffused through the round window membrane into the inner ear. Intratympanic steroids may be delivered via a needle through the tympanic membrane or may be placed into the middle ear through a tympanostomy tube or a myringotomy incision in the eardrum. Steroids may also be delivered to the round window via a microcatheter, a MicroWick , hydrogel applications, and nanoparticles.
Transtympanic needle or tympanostomy tubes are the most frequently used . The IT delivery route has additional benefit of avoiding the considerable side effects of further systemic steroid therapy. Intratympanic steroids very rarely cause changes in serum glucose levels in patients with diabetes . They may also be given to patients with cataracts, myasthenia gravis, and glaucoma .
The principal risk appears to be a persistent tympanic membrane perforation at the injection site. This complication, however, is rare and frequently resolves spontaneously or with a paper patch myringoplasty in the office. Existing studies showed considerable variability in the dose and concentration of steroids administered, the timing, frequency, and total number of injections ranging from one to several to continuous ; and drug selection dexamethasone and methylprednisolone .
This high degree of variability makes it difficult to compare the results across studies. Despite this variability, 3 of the 4 RCTs evaluating intratympanic steroids as salvage therapy found that IT steroids improved hearing outcomes beyond placebo.
Max benefit achieved by profound shnl patient All patients showed almost complete recovery. IT steroids administered through PET after posteroinferiortympanotomy. Four applications of either methylprednisone IT steroid therapy via microcatheter continuous infusion.
