Audiology Report Analysis - Damche Dorji (UHID 9B96F48329)
Patient: Damche Dorji, Male, 43 years old (DOB: 3/2/1983)
Hospital: Jigme Dorji Wangchuck National Referral Hospital, Thimphu, Bhutan
Test Date: 23 July 2026 | Referring Consultant: Dr. Tika Ram Adhikari, ENT & Head Neck Surgery
Audiologist: Jigme Dorji (MHPC No. ASLP-1751)
1. Pure Tone Audiometry (PTA) Results
Right Ear (RE) - Air Conduction (AC) Thresholds
| Frequency | 500 Hz | 1 kHz | 2 kHz | 4 kHz |
|---|---|---|---|---|
| AC (dB HL) | 75 | 95 | 100 | 90 |
| BC (dB HL) | 55 | 75 | 80 | 75 |
| AC Mask | 40 | 40 | 40 | 40 |
| BC Mask | 40 | 40 | 40 | 40 |
Note: Values reconstructed from the key frequencies; 125 Hz AC = 60 dB, BC = 45 dB.
Right PTA Average (500 Hz, 1 kHz, 2 kHz): ~90 dB HL (AC), ~70 dB HL (BC)
Air-Bone Gap (ABG) Right: ~20 dB across speech frequencies
Left Ear (LE) - Air Conduction Thresholds
| Frequency | 500 Hz | 1 kHz | 2 kHz | 4 kHz |
|---|---|---|---|---|
| AC (dB HL) | 10 | 15 | 15 | 20 |
| BC (dB HL) | 10 | 10 | 10 | 10 |
Left PTA Average: ~13.3 dB HL (AC), ~10 dB HL (BC)
2. Tympanometry (Immittance)
| Ear | ECV | Compliance | Pressure | Gradient |
|---|---|---|---|---|
| Right | 1.34 ml | 0.70 ml | +7 daPa | 49 daPa |
| Left | 1.26 ml | 0.67 ml | +2 daPa | 49 daPa |
- Bilateral Type A tympanograms - normal middle ear pressure, normal compliance, intact tympanic membranes on both sides.
3. Acoustic Reflex Testing
All ipsilateral and contralateral reflexes are absent (N.F. - No Finding) bilaterally at maximum stimulus levels (90-100 dB HL). This is expected on the right given the severe hearing loss, but absent reflexes on the left despite normal hearing thresholds is a significant finding warranting further investigation.
4. Audiologist's Diagnosis Summary
- Right Ear: Severe mixed hearing loss
- Left Ear: Hearing sensitivity within normal limits
- Immittance: Bilateral Type A tympanograms with absent acoustic reflexes
- Clinical note: ?Sudden hearing loss - ENT review recommended
5. Interpretation
Right Ear - Severe Mixed Hearing Loss
The right ear shows a severe mixed hearing loss averaging ~90 dB HL by AC. The presence of an air-bone gap of approximately 20 dB confirms a conductive component superimposed on a sensorineural deficit (BC average ~70 dB HL - which itself falls in the severe sensorineural range). The audiogram configuration is broad/flat to moderately sloping, which is a particularly poor prognostic sign for recovery.
The Type A tympanogram (normal compliance, normal pressure) rules out middle ear effusion, perforation, or ossicular fixation as the cause of the conductive component. Given this, possible causes of the conductive component include:
- Perilymphatic fistula
- Otosclerosis (early/mild)
- Third window lesion (superior semicircular canal dehiscence)
- Subtle ossicular abnormality not detectable on tympanometry alone
The sensorineural component suggests cochlear or retrocochlear pathology.
Left Ear - Normal
Within normal limits at all frequencies. No intervention required for the left ear at this time.
6. Prognosis
Right Ear - Guarded to Poor
Several factors in this case are associated with a poor prognosis for hearing recovery, based on established prognostic indicators (K.J. Lee's Essential Otolaryngology):
| Prognostic Factor | This Patient | Impact |
|---|---|---|
| Degree of loss | Severe (~90 dB AC) | Unfavorable - more severe loss = worse recovery |
| Audiogram shape | Flat / broad frequency loss | Unfavorable - flat/high-freq loss predicts poor recovery |
| Age | 43 years | Borderline - median age for ISSNHL; younger patients generally do better |
| Vertigo | Not documented | Favorable if absent; would be unfavorable if present |
| Bilateral involvement | Unilateral (right only) | Favorable |
| Middle ear status | Normal tympanogram | Favourable - no effusion |
According to a 2024 systematic review and meta-analysis (Ying et al., Laryngoscope 2024, PMID 38808803), even without treatment, approximately 36% of ISSNHL patients gain at least 30 dB, and 70% gain at least 10 dB within 3 months. However, this patient's loss is already at the severe-to-profound end, meaning even a 30 dB gain would leave significant residual impairment.
The mixed nature of the hearing loss (conductive + sensorineural) is also important: if the conductive component has a reversible cause (e.g., perilymphatic fistula or an early conductive pathology), partial recovery of the conductive component is possible with appropriate management. The sensorineural component at this severity carries a guarded outlook.
Key prognostic summary:
- If this represents idiopathic sudden SNHL: guarded prognosis. Immediate high-dose systemic corticosteroids (within the treatment window, ideally within 2-4 weeks of onset) offer the best chance of partial recovery. Intratympanic steroids are an option as first-line or salvage therapy. - K.J. Lee's Essential Otolaryngology
- If a structural/vascular cause is identified (e.g., retrocochlear lesion, vascular occlusion): prognosis depends on the underlying etiology.
- Without treatment or if the treatment window has passed: spontaneous recovery of some hearing is possible but the chance of meaningful functional recovery from severe loss is low.
7. Recommended Next Steps (per Audiologist's advice)
- Urgent ENT review - confirmed in the report; should not be delayed given the ?sudden onset
- MRI of the internal auditory canals with gadolinium - to rule out vestibular schwannoma or retrocochlear pathology, which can present with sudden SNHL
- Establish onset timeline - if truly sudden and within the treatment window, systemic/intratympanic corticosteroids should be initiated promptly
- High-resolution CT temporal bones - to evaluate for otosclerosis, superior semicircular canal dehiscence, or other structural causes of the mixed loss
- Repeat audiogram - serial audiograms to monitor progression or recovery
- Acoustic reflex decay and otoacoustic emissions (OAEs) - to further characterize the nature and site of lesion
- Hearing rehabilitation planning - Given the severity of right-sided loss, if medical treatment fails to recover hearing, hearing aid fitting or bone-anchored hearing aid (BAHA) options should be discussed. Cochlear implant candidacy assessment may eventually be relevant if loss progresses or is bilateral.
Bottom line: This is a 43-year-old male with a severe mixed hearing loss in the right ear, audiologically suspicious for sudden onset. The prognosis for meaningful functional recovery is guarded, primarily due to the severity of the loss and the broad flat audiogram configuration. Early specialist review and prompt treatment initiation remain the most important modifiable prognostic factors. The left ear is normal and should be protected.

I now have comprehensive data to give a thorough, evidence-based response.
Prednisolone Treatment for Damche Dorji - Clinical Context & Updated Prognosis
Is Prednisolone the Right Choice?
Yes - it is the correct first-line treatment. Prednisolone (a corticosteroid) is the standard pharmacological intervention for suspected idiopathic sudden sensorineural hearing loss (ISSNHL). The prescription is appropriate and aligns with international guidelines.
Standard Dosing Regimens
There is no single universally accepted regimen, but the most widely used protocols are:
| Regimen | Protocol | Source |
|---|---|---|
| ENT-UK Standard | 1 mg/kg/day for 7 days, then tapered over 5 days | Balai et al., Auris Nasus Larynx 2024 |
| High-dose oral taper | 60 mg/day × 10-14 days with short taper | Textbook of Family Medicine 9e |
| Scott-Brown reducing course | 60 mg day 1 → 50 mg day 2 → 40 mg × 3 days → 30 mg × 3 days → further reduction over 3 weeks | Scott-Brown's Otorhinolaryngology |
| Intratympanic equivalent | 4 doses of methylprednisolone 40 mg/mL over 2 weeks (non-inferior to oral) | Goldman-Cecil Medicine |
For this patient (43-year-old male): The 1 mg/kg/day dosing (ENT-UK) is practical. At approximately 60-70 kg body weight, this corresponds to 60-70 mg/day prednisolone for 7 days, tapering over the following 5 days - a 12-day course total.
What to Expect with Treatment - Updated Prognosis
Prednisolone modestly but meaningfully improves outcomes compared to no treatment. Here is how the evidence applies to this patient:
Realistic Outcome Expectations
| Outcome Category | Without Treatment | With Oral Corticosteroids |
|---|---|---|
| ≥30 dB recovery | ~36% | Improved, but evidence shows mixed benefit |
| ≥10 dB recovery | ~70% | Higher rates reported |
| Complete recovery | ~1/3 of patients | ~45.8% with high-dose regimens in some studies |
| No improvement | ~1/3 of patients | Reduced but still possible |
(Data: Ying et al. Laryngoscope 2024, PMID 38808803; Balai et al. Auris Nasus Larynx 2024, PMID 37127508)
This Patient's Specific Prognosis on Prednisolone
The outlook remains guarded despite treatment, because:
- Baseline loss is severe (~90 dB AC right ear) - even a 30 dB gain leaves him in the moderate-severe range (~60 dB), with significant functional impairment
- Flat/broad audiogram - the worst prognostic audiometric shape; high-frequency or sloping losses tend to recover better than flat losses
- Mixed component - the sensorineural component (BC ~70 dB) is unlikely to recover fully; the conductive component may respond if a reversible cause is identified
A 2024 systematic review (Balai et al.) found high-dose regimens achieved a mean hearing gain of up to 44.4 dB and complete recovery in 45.8% of cases - but these figures are for the whole ISSNHL population, not specifically for severe losses at this threshold level. Patients with profound/severe loss at baseline do worse even with treatment.
Critical Monitoring Points
When to assess response:
- Week 1-2: Clinical review; initial subjective improvement (e.g., tinnitus change) may be noted before audiometric change
- Week 3-4: Repeat pure tone audiogram - the primary objective measure of treatment response
- 4-6 weeks post-onset: If no response to oral prednisolone, intratympanic steroid injection (salvage therapy) should be considered - this is well-supported by evidence and the audiologist's report should guide ENT on candidacy
Red flags requiring immediate reassessment:
- Worsening of hearing on the treated side
- New vertigo or onset/worsening balance problems
- Contralateral (left) ear deterioration
What Prednisolone Does NOT Address
| Gap | Recommended Action |
|---|---|
| Conductive component (ABG ~20 dB, right) | CT temporal bones to identify cause |
| Absent acoustic reflexes bilaterally | MRI internal auditory canals with gadolinium to exclude vestibular schwannoma |
| Underlying cause remains unknown | Autoimmune, vascular, and infectious workup (ESR, FBC, autoimmune screen, lipid profile) |
If Prednisolone Fails
If there is no meaningful audiometric recovery by 4-6 weeks, options include:
- Intratympanic dexamethasone or methylprednisolone (salvage) - controlled studies show improved outcomes - Textbook of Family Medicine 9e
- Hyperbaric oxygen therapy - may be helpful, especially in combination with steroids (Alter et al., Laryngoscope 2026, PMID 40747804)
- Hearing rehabilitation - if medical treatment does not restore functional hearing, right-ear hearing aid fitting or bone-anchored hearing aid (BAHA) assessment is the next step
- MRI remains mandatory if hearing does not recover - to rule out vestibular schwannoma
Key Point for Clinician
The treatment window for prednisolone in SSNHL is ideally within 2 weeks of onset, and up to 4-6 weeks at the outside. The report is dated 23 July 2026 - establishing the exact date of onset from the patient is important to determine whether the patient is still within the therapeutic window and whether prednisolone can still achieve meaningful benefit.
What do you mean by guarded
"Guarded prognosis" is a clinical term meaning the outcome is uncertain and cannot be predicted with confidence - recovery is possible but not likely to be complete, and there is a real chance of little or no improvement.
In plain terms for this patient:
What "Guarded" Means Here
Think of it as a spectrum:
| Prognosis Term | Plain Meaning |
|---|---|
| Good | Full or near-full recovery expected |
| Fair | Partial recovery likely |
| Guarded | Outcome is uncertain; partial recovery possible, but significant residual loss is likely |
| Poor | Little to no recovery expected |
Why "Guarded" Specifically for Damche Dorji
His right ear currently has a ~90 dB hearing loss - this is in the severe range, just below profound. Three factors make full recovery unlikely:
-
The more severe the loss, the harder it is to recover. Research shows patients with mild-moderate sudden losses recover far better than those with severe losses like his.
-
The audiogram shape is flat across all frequencies. Flat audiograms are a known poor prognostic sign - sloping high-frequency losses tend to recover better.
-
Even the best-case treatment data (prednisolone high-dose) shows a mean hearing gain of ~44 dB in responders. If he gains 40-44 dB, his right ear would move from ~90 dB to ~46-50 dB - that is still a moderate hearing loss, not normal hearing.
The Three Realistic Scenarios
| Scenario | Probability | What it Means for the Patient |
|---|---|---|
| Good response | ~1 in 3 | Gains 30+ dB - hearing becomes moderate range; may manage without a hearing aid |
| Partial response | ~1 in 3 | Gains 10-30 dB - still has significant loss; will likely need a hearing aid |
| No response | ~1 in 3 | No meaningful change; severe loss persists; hearing aid or BAHA needed |
Bottom line: "Guarded" simply means we cannot promise good news, but we are not giving up - treatment is underway and we will reassess in 3-4 weeks with a repeat audiogram to see which of those three scenarios he falls into. His left ear is completely normal, which means his overall communication ability is preserved on that side throughout this process.
The patient also has history of migraine and dizziness

This history is highly significant. Here is the full updated picture:
Impact of Migraine + Dizziness History on Diagnosis and Prognosis
Why This Changes Everything
Migraine is a recognised cause of sudden sensorineural hearing loss and cochlear symptoms. Adding dizziness to that history opens up several important diagnostic possibilities that were not apparent from the audiogram alone. The diagnosis of "idiopathic" sudden hearing loss must now be reconsidered.
New Differential Diagnoses to Consider
1. Vestibular Migraine (VM) with Cochlear Involvement
This is now the most important differential to consider. Vestibular migraine affects ~2.7% of the general population and is frequently misdiagnosed. It is now well-established that migraine can cause:
- Episodic dizziness and vertigo
- Fluctuating low-frequency sensorineural hearing loss (reported in 50% of patients in one study)
- Tinnitus (in 15-60% of migraine patients)
- Aural fullness
- Sudden hearing loss - directly linked to migraine-induced vasospasm of the cochlear vasculature
2. Cochlear Migraine
An emerging entity where migraine causes cochlear symptoms (hearing loss, tinnitus, aural fullness) without prominent vestibular symptoms. Ma et al., Curr Med Sci 2021, PMID 34403087 specifically links migraine to sudden sensorineural hearing loss through this mechanism.
3. Meniere's Disease
- The triad of episodic vertigo + fluctuating sensorineural hearing loss + tinnitus overlaps with migraine in presentation
- Migraine and Meniere's disease are known to co-occur and are clinically difficult to separate
- His dizziness history, combined with the right-ear SNHL, makes Meniere's a real differential
- However, his tympanogram shows normal compliance (not the low-frequency conductive pattern typical of Meniere's endolymphatic hydrops)
4. Basilar/Posterior Circulation Migraine
- A subtype where brainstem ischemia causes hearing loss, vertigo, neurologic symptoms, and headache together
- At age 43, this warrants MRI to exclude a vascular or posterior fossa lesion - Cummings Otolaryngology
5. Original ISSNHL Diagnosis Still Possible
Migraine is a known risk factor for ISSNHL (not just a mimic). Vasospasm from migraine can trigger true cochlear ischaemia causing irreversible sudden hearing loss.
How the Migraine/Dizziness History Affects Prognosis
| Factor | Without Migraine History | With Migraine + Dizziness History |
|---|---|---|
| Cause | Idiopathic | May be migraine-driven (vasospasm/cochlear migraine) |
| Hearing loss pattern | Fixed, unlikely to fluctuate | Could be fluctuating - may partially improve and worsen |
| Prognosis | Guarded (as discussed) | Potentially more treatable if migraine is the driver |
| Treatment implications | Prednisolone only | Add migraine management alongside steroids |
| Risk of recurrence | Low | Higher - if migraine is the cause, further attacks can occur |
This is actually a reason for cautious optimism - if migraine-related vasospasm is driving the hearing loss, treating the underlying migraine may help stabilise or even partially recover hearing, and can prevent future episodes.
What Should Be Added to His Management Now
Immediate
- Detailed migraine history - characterise the dizziness: is it true vertigo (room spinning)? Timing relative to headaches? Duration of dizziness episodes?
- Ask specifically: Did the hearing loss occur during or around a migraine attack? Was there aural fullness or tinnitus preceding it?
Investigations
- MRI brain + internal auditory canals with gadolinium - now even more urgent, both to exclude vestibular schwannoma and to look for posterior circulation or white matter changes associated with migraine
- Electrocochleography (ECochG) - to evaluate for endolymphatic hydrops (Meniere's)
Treatment additions
-
Migraine prophylaxis - if vestibular migraine is confirmed as a contributor, prophylactic agents such as:
- Beta-blockers (propranolol, metoprolol)
- Tricyclic antidepressants (nortriptyline)
- Valproate or topiramate
- Dietary modification - avoiding triggers (caffeine, aged cheese, alcohol, MSG, irregular sleep)
- Magnesium supplementation (400 mg/day) - evidence in migraine reduction - Cummings Otolaryngology
- Riboflavin (Vitamin B2) 400 mg/day - shown more effective than placebo for migraine frequency reduction
-
Continue prednisolone as prescribed - it remains appropriate regardless of the underlying cause
Key Clinical Point
The combination of migraine history + dizziness + unilateral sudden SNHL in a 43-year-old male is a classic presentation of vestibular/cochlear migraine or Meniere's disease, and should NOT be dismissed as coincidental. This clinical picture needs a neurotology or specialist ENT assessment beyond a routine audiogram. The treating ENT (Dr. Tika Ram Adhikari) should be made aware of this history explicitly if not already documented.
