Quick Answer: Otosclerosis is abnormal bone growth around the stapes bone in the middle ear that physically blocks sound from reaching the inner ear, causing conductive hearing loss — a different mechanism than the sensorineural, age-related loss most OTC hearing aids are designed around. Per the NIDCD, mild cases can be managed with a hearing aid, but a hearing aid only amplifies sound; it doesn’t stop the bone growth. Stapedectomy (or stapedotomy) surgery is the only treatment that corrects the underlying cause, and comparative research shows it typically outperforms hearing aids on speech-in-noise recognition and patient satisfaction — though it carries a small but real risk of further hearing loss. Anyone suspecting otosclerosis needs an audiogram and ENT evaluation first, since that’s what determines the air-bone gap and whether you’re a hearing aid, surgery, or bone-conduction candidate.
Most hearing aid buying guides — this site’s included — are written around one pattern: a gradual, sensorineural, age-related loss that a self-fitting OTC device can amplify straight out of the box. Otosclerosis doesn’t follow that pattern. The hearing loss is real, but the cause is mechanical, not neural, and that distinction changes which device, if any, actually fixes the problem.
Otosclerosis, by the numbers
- More than 3 million Americans are affected by otosclerosis, according to the NIDCD, with white, middle-aged women at the highest risk.
- Tinnitus shows up in roughly 72% of otosclerosis patients, per clinical research — a significantly higher rate than in the general population, and often the symptom that prompts someone to get evaluated in the first place.
- Surgical candidacy is generally defined by an air-bone gap greater than 20 dB, and one single-institution stapedotomy series reported profound sensorineural hearing loss in 0.21% of patients and non-profound sensorineural loss in 3.2%, with a revision-surgery rate around 4.5%.
- Bone conduction hearing device candidacy typically requires bone-conduction thresholds better than 45 dB HL and a speech discrimination score of 60% or higher.
What otosclerosis actually does to your ear
Normal hearing depends on three tiny middle-ear bones — the malleus, incus, and stapes — passing sound vibrations along to the inner ear. In otosclerosis, abnormal bone remodeling causes the stapes to become fixed in place instead of vibrating freely, which blocks sound from getting through. That’s why otosclerosis produces conductive hearing loss rather than the sensorineural loss caused by inner-ear nerve damage: the sound-detecting machinery in the cochlea is intact, but the sound isn’t reaching it. Per the NIDCD, the loss usually starts in one ear and moves to the other over time, often appearing very gradually, and low-pitched sounds are frequently the first to go — which is a different early pattern than the high-frequency loss that typically shows up first with age-related hearing loss.
Why this matters for choosing a hearing aid
OTC hearing aids are built, marketed, and self-fit around a specific assumption: a stable, mild-to-moderate, sensorineural loss, the kind that shows up gradually with age. Otosclerosis technically fits the “mild-to-moderate” and often “gradual” parts of that description, which is part of why the NIDCD says a hearing aid can treat mild cases. But conductive hearing loss behaves differently from sensorineural loss in ways a generic self-fitting profile doesn’t account for — the amount of amplification needed to overcome a mechanical blockage isn’t necessarily the same curve an OTC device calculates from a standard hearing screener built around sensorineural patterns. That gap is exactly why an audiogram matters here more than for typical age-related loss: it’s what tells you (and, ideally, an audiologist) whether you’re dealing with a straightforward conductive loss a hearing aid can manage, a mixed loss, or a case where surgery is the better first move.
Hearing aid vs. stapedectomy vs. bone conduction
| Option | What it does | Best for | Trade-off |
|---|---|---|---|
| Conventional hearing aid | Amplifies sound; doesn't touch the bone growth | Mild, stable conductive loss, or anyone declining surgery | Doesn't stop progression; may need reprogramming as the gap widens |
| Stapedectomy / stapedotomy | Replaces the fixed stapes with a prosthetic, restoring conduction | Confirmed air-bone gap over ~20 dB, good surgical candidate | Small but real risk of further (sensorineural) hearing loss; ~4.5% revision rate |
| Bone conduction hearing device | Sends sound through skull bone, bypassing the middle ear | Advanced conductive/mixed loss, or not a surgical candidate | Requires a dedicated device, not a standard hearing aid |
For someone with a confirmed mild, stable conductive loss who wants to try amplification before considering surgery, a lab-tested OTC pick like the Jabra Enhance Select 300 (also sold under Jabra’s newer M-series naming as the M2, around $1,695/pair) is a reasonable starting point — but it’s still worth confirming with an audiologist that a conventional hearing aid, rather than a bone conduction device, is the right fit for your specific air-bone gap.
Jabra Enhance Select 300 — for confirmed mild, stable conductive loss
- A reasonable first step once an audiologist has confirmed a mild, gradual conductive loss and ruled out a large air-bone gap that would point toward surgery instead.
- Not a substitute for the ENT workup — otosclerosis is a case where the diagnosis, not the device, is the hard part.

Red flags: get an audiogram before you shop
Otosclerosis can’t be self-diagnosed from how muffled things sound — the only way to know whether you’re dealing with conductive, mixed, or sensorineural loss (and how big any air-bone gap is) is a formal hearing test. See an audiologist or ENT promptly if you notice: hearing loss that started in one ear and seems to be spreading to the other; low-pitched sounds becoming harder to hear before high-pitched ones; new or worsening tinnitus; or any hearing change during or after a pregnancy. This article is general information, not medical advice — a proper audiogram is what actually determines which of the options above applies to you.

The bottom line
Otosclerosis causes a mechanical, conductive hearing loss — not the sensorineural pattern OTC hearing aids are designed around — so a hearing aid can help with mild, confirmed cases but does nothing to the bone growth actually causing the problem. Get an audiogram and ENT evaluation first; that’s what determines whether a conventional hearing aid, stapedectomy surgery, or a bone conduction device is the right next step, not a self-administered hearing screener.
