Stages with a signal

Clinical definition (Orphanet)

A rare otorhinolaryngologic condition characterized by sudden hearing loss of at least 30 decibels across three contiguous frequencies, within 72 hours or less, due to acute damage to the cochlear hair cells, resulting from acoustic trauma or mechanical trauma during surgery, or occurring without any known cause. The hearing loss may affect one or both ears. Typical concomitant symptoms are aural fullness, tinnitus, and vertigo. Patients may fully recover or remain with hearing loss of variable intensity.

How rare: 1-5 / 10 000 — about one to five people per ten thousand (still uncommon, but less ultra-rare).

Trial readiness signals

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology

Genes and phenotypes

Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.

Do we know what causes it?

Not yet — the cause hasn't been pinned down in GenCC.

No strong gene–disease assertion joined for this Orphanet entity.

Phenotypes (Monarch / HPO)

Not enriched in this build — Monarch phenotype joins were not run for this record.

Animal models (Monarch / Alliance)

Not enriched in this build.

Literature

Is anyone studying this?

4,559

4,559 papers have been published on this condition. That is a real research literature — still far smaller than common diseases (breast cancer: over 700,000 papers). Median papers in the last 10 years for a rare disease in this dataset (publications denominator n=5449) is 41.

4,559 papers since the earliest indexed year in this search — median last-10-year count for a rare disease in this dataset is 41 (publications denominator n=5449).

Clinical research

Is a treatment being tested?

32

interventional trials for this specific condition

32 interventional trials matched this specific condition name; 13 currently recruiting in our sample.

Data as of 27 July 2026

32 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 95.9th percentile).

Recruiting interventional trials

From the matched ClinicalTrials.gov set

32 interventional trials matched after quoted-phrase search and title/condition post-filter.

Observational and natural-history studies

11 observational studies match this condition. These do not test a treatment and are not counted in the interventional-trial headline, but they are genuine research: natural-history work often defines the endpoints needed for a future rare-disease trial, and families may be able to enroll.

Where to find support

We do not yet link condition-specific patient organisations. These umbrella groups support undiagnosed and ultra-rare families:

India — NPRD

Last verified 2026-07-26

This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.

Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.

How we counted this

Europe PMC query (preferred label + any corrected label + Orphanet and Mondo exact synonyms, stoplisted; unioned with resolved MeSH labels when available). UMLS / OMIM / NCIT cross-references are stored on the overview but are not added to the query string.

MeSH descriptor terms unioned into the query: Hearing Loss, Sudden

ClinicalTrials.gov query (quoted phrases + MeSH via query.cond, plus recall-expansion terms when used):

"Sudden sensorineural hearing loss" OR "Secondary acute sensorineural hearing loss" OR "Hearing Loss, Sudden"

Interventional trials matched via: both, phrase, mesh (mesh = registered under a MeSH descriptor no name phrase would catch; recall-expansion = gene / selected parent terms used only for trials).

Study-type breakdown: 32 interventional · 11 observational · 0 expanded access. Only interventional studies enter the trial headline.

Confidence reasoning

  • Preferred label is multi-word and distinctive
  • No synonyms dropped by stoplist
  • No label/synonym collisions with other diseases in this corpus
