A pioneering operation using 3D-printed titanium bones helped a man hear again. Now, Professor Mashudu Tshifularo hopes clinical trials will bring the technology to more patients.
In 2019, a South African surgeon accomplished something extraordinary: he helped restore a patient’s hearing using tiny, specially manufactured titanium bones.
Seven years later, that achievement is entering another important chapter.
Professor Mashudu Tshifularo, an ear, nose and throat specialist at the University of Pretoria, announced plans in May 2026 for clinical trials involving 45 people with severe conductive hearing loss.
The development raises a remarkable possibility: Could a surgical innovation pioneered in South Africa eventually help many more people regain the sounds they have lost?
A Historic Operation in Pretoria
On March 13, 2019, Tshifularo and his medical team at Steve Biko Academic Hospital performed a pioneering middle-ear reconstruction using 3D-printed titanium implants.
The procedure replaced damaged structures known as the ossicles — three of the smallest bones in the human body.
These tiny bones play an essential role in hearing. They transmit vibrations from the eardrum toward the inner ear, allowing sound to be processed by the auditory system.
When the ossicles become damaged through injury, infection or certain birth defects, sound may no longer travel efficiently through the middle ear. This condition is called conductive hearing loss.
By replacing damaged bones with specially designed implants, surgeons may be able to restore the pathway through which sound travels.
The Patient Behind the Breakthrough
The first widely reported patient was Thabo Molishiwa, who had experienced serious ear injuries and significant hearing loss.
In a 2019 interview published by the University of Pretoria, Molishiwa described years of pain and uncertainty before agreeing to the experimental procedure.
He initially hesitated because he feared the risks of undergoing an unfamiliar operation. Eventually, he decided to proceed.
The results changed his life.
In that interview, Molishiwa estimated that he had recovered approximately 75% of his hearing.
But the story did not end there.
At a University of Pretoria event in April 2026, the patient appeared in a video confirming that his hearing had remained excellent in the years following surgery, according to the university.
That long-term account provides an encouraging sign, although a successful individual case does not establish how reliably the procedure will work for other patients.
How Can 3D-Printed Bones Restore Hearing?
The technology combines modern manufacturing with delicate reconstructive surgery.
Rather than relying entirely on conventional replacement structures, the team developed titanium implants intended to reproduce the anatomy of damaged middle-ear bones.
Titanium is widely used in medical implants because it is generally compatible with human tissue.
The approach is designed to address the specific structures preventing sound from traveling properly through the ear.
The 2026 version of the procedure also incorporates robotic-assisted surgical technology, intended to improve precision during delicate operations.
According to the University of Pretoria, the procedure takes approximately three hours.
The goal is to restore hearing while limiting damage to surrounding structures. However, these potential advantages still require careful evaluation through formal clinical research.
Why the 2026 Clinical Trials Matter
In May 2026, the University of Pretoria announced that 45 patients with conductive hearing loss were awaiting clinical trials at Steve Biko Academic Hospital.
The university reported that the project had obtained the regulatory, ethical and licensing clearances needed to move forward.
Several South African organizations are involved in developing and producing the technology, including the Council for Scientific and Industrial Research, HH Industries and Marcus Medical.
The trials are intended to help researchers evaluate the procedure’s effectiveness, safety and suitability for wider medical use.
If the results are favorable, the research could support future training, scientific publications and broader access to the technology.
As of the university’s May announcement, the clinical trials were planned rather than completed. Their eventual results should not be assumed.
Does This Surgery Cure Deafness?
This is one of the most important distinctions in the story.
The operation is intended for certain types of conductive hearing loss, particularly when damage to the middle-ear bones interferes with sound transmission.
It is not a universal cure for deafness.
Other forms of hearing loss may involve damage to the inner ear, auditory nerve or other parts of the hearing system. Replacing middle-ear bones would not necessarily correct those conditions.
Even among patients with conductive hearing loss, suitability depends on the specific medical cause and an evaluation by a qualified specialist.
That makes the planned clinical trials particularly important: researchers must establish which patients are most likely to benefit and what risks may be involved.
An Innovation Years in the Making
Tshifularo’s achievement was not an overnight success.
In a 2019 interview, he described spending approximately a decade pursuing his research and encountering skepticism from organizations that were unwilling to support his ideas.
His determination eventually brought together medicine, engineering and 3D-printing technology.
The result became a milestone for South African medical innovation.
And the surgeon’s ambitions extend beyond a single successful operation.
He hopes the technology can be developed, tested and taught to other medical teams, potentially expanding treatment options for people whose hearing loss is caused by damaged middle-ear structures.
What Happens Next?
The next major milestone will be evidence from the planned clinical trials.
Researchers will need to examine hearing outcomes, complications, durability and the procedure’s performance across a larger group of patients.
Until those findings are available, the 2019 success remains a promising early achievement rather than proof of a widely established cure.
Still, the larger story is remarkable.
A patient who struggled to hear became part of a pioneering medical operation. Years later, his reported recovery continues to inspire efforts to help others.
For Professor Tshifularo, the ultimate goal is bigger than one surgical breakthrough.
It is a future in which more people with treatable hearing loss have a chance to hear again.
Have You Heard? Sometimes the most extraordinary medical discoveries aren’t just about what surgeons accomplished years ago — they’re about what those achievements might make possible tomorrow.
