Stapedectomy vs Stapedotomy: Which Surgery Is Better for Otosclerosis?

If you’ve been diagnosed with otosclerosis, your ENT specialist may recommend surgery to improve hearing. Two common surgical options are stapedectomy and stapedotomy. Both procedures are designed to bypass a fixed stapes bone and restore sound transmission to the inner ear. However, they differ in surgical technique, recovery, risks, and hearing outcomes. In this guide, we’ll compare stapedectomy vs stapedotomy to help you understand which procedure may be recommended for your condition.

What Is Otosclerosis?

Otosclerosis is a condition in which abnormal bone growth develops around the stapes bone in the middle ear. Over time, the stapes becomes fixed and loses its ability to vibrate normally, preventing sound waves from reaching the inner ear effectively. This commonly results in progressive conductive hearing loss and may also cause tinnitus or balance-related symptoms in some individuals.

Symptoms of Otosclerosis

The symptoms of otosclerosis may develop gradually and can include:

• Progressive hearing loss
• Difficulty hearing low-frequency sounds
• Ringing in the ears (tinnitus)
• Difficulty understanding conversations
• Family history of hearing loss
• Dizziness or balance problems in some cases

If left untreated, otosclerosis can significantly affect communication and quality of life.

What Is Stapedectomy?

Stapedectomy is a surgical procedure to treat hearing loss caused by otosclerosis, a condition where the stapes bone gets fixed and cannot vibrate to transmit sound from the middle ear to the inner ear. Stapedectomy is one of several advanced ear surgery procedures used to restore hearing and improve sound transmission in patients with middle ear disorders.

In this procedure, the fixed stapes bone is replaced with an artificial prosthetic device to restore hearing and sound transmission.

What Is Stapedotomy?

Stapedotomy is a refined and less invasive procedure compared to stapedectomy. This is performed to treat conductive hearing loss from otosclerosis. In this surgery, a small, tiny hole is created in the stapes footplate to insert a prosthetic piston, helping to bypass the diseased bone to restore sound transmission.

Key Differences Between the Two Procedures

Both Stapedectomy and Stapedotomy are highly successful surgical procedures to treat hearing loss caused by otosclerosis. However, stapedotomy is preferred today, as it involves using a laser/drill to create a small hole in the stapes footplate for a prosthesis, resulting in better safety and high-frequency hearing.

On the other side, stapedectomy involves the removal of the entire footplate.

Major Key Differences:

Procedure Technique

• Stapedectomy involves the complete removal of the stapes footplate, which is replaced by a larger prosthesis device.
• Stapedotomy is a less invasive and small-fenestra approach (technique to create a small hole in the footplate).

Safety Profile:

Stapedotomy is generally associated with a lower risk of inner ear trauma and postoperative complications compared to traditional stapedectomy, because it results in fewer intraoperative and postoperative complications, as the inner ear is less disturbed.

While stapedectomy is associated with higher incidences of postoperative vertigo.

End Result:

Stapedotomy is currently the preferred surgical technique in most cases because it is less invasive and generally associated with comparable or slightly improved hearing outcomes, fewer complications, and better preservation of high-frequency hearing.

Tools Used:

In stapedotomy, surgeons use lasers or specialised microdrills to create a tiny hole in the stapes footplate.

While in stapedectomy, surgeons use operating microscopes, laser systems (CO2, Argon, or KTP), and micro-instruments like picks, hooks, and scissors.

How These Surgeries Treat Hearing Loss

Both of these surgical procedures are highly effective and provide hearing improvement. In some cases, patients with hearing problems caused by a perforated eardrum may require myringoplasty instead of stapes surgery. However, to have a clear understanding of how these surgeries treat hearing loss, depending on the underlying cause of hearing loss, ENT specialists may recommend different surgical treatments. For example, tympanoplasty is commonly performed to repair a damaged eardrum or middle ear structures, while stapedectomy and stapedotomy are specifically used for otosclerosis-related hearing loss. Here is the explanation:

The Problem: Otosclerosis

In this condition, the stapes bone becomes frozen or fixed, stopping the sound vibrations from reaching the inner ear. This causes hearing loss.

Stapedectomy:

Stapedectomy is performed to remove the fixed or frozen stapes bone completely.

Procedure:

• The ENT surgeon makes an incision into the ear canal and lifts the eardrum to access the middle ear.
• From the middle ear, the stapes bone is removed completely, including the base called the footplate.
• The incision is covered with a small tissue, protecting the inner ear.
• The stapes bone is replaced by a prosthetic device, which is usually made up of Teflon or titanium.
• The prosthesis device helps connect the remaining middle ear bones to the inner ear, transmitting vibrations for better hearing.

Stapedotomy:

Stapedotomy is a less invasive and yet modern surgical procedure. Instead of removing the entire stapes bone, it creates a tiny hole.

Procedure:

• The ENT surgeon usually removes the upper/top part of the fixed stapes bone, called the superstructure.
• A small laser or micro drill is used to create a small hole in the base of the frozen stapes bone.
• Through this hole, a prosthetic device, like a piston, is inserted, connecting the incus to the inner ear. This device acts like a bridge to connect the incus (the middle bone of the three tiny middle-ear bones: malleus, incus, stapes) with a vestibule (where the prosthesis is inserted).

Both surgical procedures involve prosthetic devices that allow sound vibrations to bypass the fixed stapes bone.

The result: The inner ear receives vibrations, converting them into nerve signals for the brain, which effectively results in better hearing.

Comprehensive Table of the Comparison

Feature	Stapedectomy (Total/Subtotal Removal)	Stapedotomy (Small Hole Method)
Technique	Removal of the entire top structure (superstructure) and the base (footplate) of the stapes bone.	Creating a small, precise hole (0.4–0.6 mm) in the footplate using a laser or micro-drill.
Prosthesis	Wire-tissue or small piston.	Typically, a piston prosthesis (Teflon or wire).
Risks (Low Overall)	Higher risk of vertigo, perilymph fistula (fluid leak), and sensorineural hearing loss.	Lower risk of complications; less trauma to the inner ear.
Common Complications	Vertigo, temporary taste disturbance, tinnitus, and persistent conductive loss.	Similar to stapedectomy, but at lower rates. Taste disturbance is common but usually temporary.
Recovery Time	Generally, 1–2 weeks for daily activities, 4-6 weeks for full recovery.	Often faster rehabilitation than stapedectomy, with similar restrictions.
Hearing Results	Excellent, but may have slightly lower high-frequency gain than stapedotomy.	Superior high-frequency hearing improvement; lower incidence of high-frequency hearing loss.
Long-term Success	High success rate, but slightly higher revision rate due to complications.	High success rate with better long-term stability in high frequencies.
When it’s used	Usually, if the footplate is severely affected or in revision surgery.	Preferred primary technique for most otosclerosis cases.

Who Is a Candidate for Stapes Surgery?

Stapedectomy or stapedotomy may be recommended for patients who:

• Have conductive hearing loss caused by otosclerosis
• Have difficulty hearing despite medical management
• How is evidence of stapes fixation on hearing evaluation
• Have healthy inner ear function
• Are medically fit for surgery

A detailed hearing assessment and ENT examination help determine whether stapes surgery is appropriate.

Recovery After Stapedectomy and Stapedotomy

Recovery following stapes surgery is usually smooth. Most patients can return to routine daily activities within 1 to 2 weeks, although complete healing may take 4 to 6 weeks.

During recovery, patients are generally advised to:

• Avoid heavy lifting
• Avoid forceful nose blowing
• Keep the ear dry
• Avoid air travel unless approved by the surgeon
• Attend scheduled follow-up appointments

Hearing improvement may be noticed gradually as the ear heals.

Risks and Possible Complications

Although both procedures are considered safe and highly successful, potential risks may include:

• Temporary dizziness or vertigo
• Taste disturbances
• Ringing in the ears (tinnitus)
• Ear infection
• Persistent hearing loss
• Rare sensorineural hearing loss
• Need for revision surgery

Which Procedure May Be Right for You?

Generally, it is considered that both stapedectomy and stapedotomy are successful procedures to treat conductive hearing loss, with an exceeding 90% – 95% success rate.

However, both are standard procedures; the stapedotomy is currently considered the safest, least invasive, modern, and most common technique used by surgeons. Stapedectomy is the traditional version of stapes bone surgery.

Ultimately, the choice between stapedectomy and stapedotomy depends on several factors, including the extent of otosclerosis, middle ear anatomy, hearing test results, and the surgeon’s clinical assessment. Your ENT specialist will recommend the most appropriate procedure based on your individual condition.
