Ossicular Reconstruction (Ossiculoplasty)
Patient Information Leaflet
1. Why am I being offered ossicular reconstruction?
You have hearing loss caused by damage or disruption to the ossicles — the three tiny bones in the middle ear (malleus, incus, and stapes) that transmit sound from the eardrum to the inner ear.
This damage may be due to:
Chronic ear infections
Cholesteatoma
Previous ear surgery
Long-standing eardrum perforation
Trauma or erosion of the hearing bones
Ossicular reconstruction (ossiculoplasty) is a surgical procedure designed to improve hearing by rebuilding this sound-conduction mechanism.
2. What is ossicular reconstruction?
Ossiculoplasty involves repairing or replacing one or more of the hearing bones using either:
Your own tissue (e.g. reshaped ossicles or cartilage), or
A biocompatible prosthesis (most commonly titanium)
The operation is usually performed alongside:
Eardrum repair (tympanoplasty), and/or
Mastoid surgery (especially if cholesteatoma is present)
The exact technique depends on what ossicles are present and mobile at the time of surgery.
3. Types of ossicular reconstruction
Depending on what remains of your natural hearing bones, your surgeon may use:
🔹 Partial Ossicular Replacement Prosthesis (PORP)
Used when the stapes (inner bone) is intact
Generally associated with more reliable hearing improvement
🔹 Total Ossicular Replacement Prosthesis (TORP)
Used when only the stapes footplate remains
Hearing improvement is still possible, but results are less predictable
Your surgeon will explain which option is most appropriate for your ear.
4. What are the expected benefits?
The main goal is to improve conductive hearing loss.
Many patients experience meaningful hearing improvement
Some patients may only have partial improvement
In a small number of cases, hearing may remain unchanged
Importantly:
Surgery cannot guarantee normal hearing
Results depend heavily on the condition of the middle ear
Modern studies show that partial reconstructions tend to yield better, more stable hearing outcomes than total reconstructions, especially when middle-ear disease is limited.
5. Factors that affect hearing outcome (important for shared decision-making)
Your surgeon will discuss factors that influence success, including:
Presence of a healthy stapes and malleus
Eustachian tube function (pressure regulation in the ear)
Ongoing or previous infection
Presence or history of cholesteatoma
Whether mastoid surgery is required
Smoking (associated with higher complication rates)
These factors help explain why outcomes vary between patients, even with the same operation
6. What are the alternatives to surgery?
In keeping with Montgomery principles, you should be aware of reasonable alternatives, including:
Hearing aids (often very effective and non-invasive)
Ongoing observation if symptoms are mild
Further medical management if infection or inflammation persists
Bone-conduction hearing devices (in selected cases)
You are not obliged to proceed with surgery, and choosing a non-surgical option will not compromise your future care.
7. What are the risks and possible complications?
All surgery carries risks. While ossiculoplasty is generally safe, it is important you understand material risks that may matter to you personally.
Hearing-related risks
No improvement in hearing
Partial or fluctuating improvement
Worsening of hearing (rare)
Need for revision surgery
Prosthesis-related risks
Displacement or extrusion of the prosthesis
Modern extrusion rates are approximately 4–5%
Risk is reduced by using cartilage protection and careful placement
Infection
Early infection: ~1–2%
Delayed or persistent discharge: higher in ears with chronic disease
Facial nerve weakness
Very rare
Usually temporary if it occurs
Permanent weakness is exceptionally uncommon
Other rare risks
Dizziness or imbalance
Tinnitus
Altered taste on one side of the tongue
Need for further surgery months or years later
Your individual risk profile may differ depending on your ear condition, and this should be explicitly discussed with you.
8. What happens during and after surgery?
During surgery
Performed under general anaesthetic
Usually lasts 1–2 hours
Often combined with eardrum repair
After surgery
Ear packing is placed and removed later
Hearing initially may be worse due to packing
Hearing is formally assessed after healing (usually 6–12 weeks)
You may be advised:
Not to blow your nose forcefully
To keep the ear dry
To avoid flying or heavy exertion for a short period (6 weeks)
9. Will I need further surgery?
Most patients do not need further surgery
Revision surgery may be required if:
The prosthesis moves or extrudes
Infection persists
Hearing outcome is unsatisfactory
Long-term studies suggest revision rates range from 5–25% over several years, particularly in ears with severe underlying disease.
10. Shared decision-making and consent
Your surgeon will:
Explain your diagnosis, treatment options, and alternatives
Discuss benefits and risks relevant to you
Answer your questions honestly
Support you in making a decision aligned with your values and priorities
You are encouraged to:
Take time to consider your options
Ask questions
Involve family or carers if you wish
Consent is an ongoing process, not a single signature.
11. When should I seek medical advice after surgery?
Contact your ENT team urgently if you experience:
Severe or worsening pain
Increasing discharge or swelling
New facial weakness
Sudden dizziness or hearing loss
Fever or signs of infection
12. Key take-home messages
Ossicular reconstruction aims to improve hearing, not guarantee normal hearing
Results depend on the health of the middle ear
Partial reconstructions generally have more predictable outcomes
Risks are low but not zero
Non-surgical alternatives are valid and effective
The decision should be shared, informed, and personalised
