KFSHRC Develops Ultra‑Micro 3D Printing Technique To Treat Inner Ear Disorders

A medical team at King Faisal Specialist Hospital and Research Centre in Riyadh has restored full balance to a patient with a rare inner ear disorder by using high-precision digital modelling and ultra-micro 3D printing to reconstruct damaged structures while preserving natural ear function and avoiding harm to sensitive internal tissues.

The patient had suffered for more than two years from severe vertigo and marked imbalance caused by an abnormal opening in the superior semicircular canal, alongside hearing weakness and strong sound sensitivity that limited daily activities and created ongoing dependence on family support until this new inner ear intervention.

Specialists in the Department of Otolaryngology at King Faisal Specialist Hospital and Research Centre developed the method entirely within the hospital, working with an ultra-micro 3D printing team to design a customised solution that reconstructs the damaged part of the inner ear outside the body before implantation.

The approach begins by digitally redesigning the affected inner ear segment using high-fidelity simulation tools, which replicate the natural shape in detail, then producing an ultra-thin implantable layer through three-dimensional micro printing that mirrors the original anatomy and can be positioned precisely without disturbing surrounding tissue or the flow of inner ear fluids that sustain balance.

For the first clinical use, the team created an extremely fine anatomical template of the superior semicircular canal defect, then used it to print a thin silicone layer that closed the abnormal opening securely, restoring the patient’s balance completely while maintaining the delicate functions of the inner ear that relate to hearing and motion detection.

Before the procedure, the inner ear disorder had deeply disrupted the patient’s quality of life, as repeated vertigo spells, constant imbalance, increased sensitivity to sounds and reduced hearing made simple movements difficult and required continuous support, so regaining stable balance after treatment marked a clear end to a long period of suffering.

According to the hospital, this digitally guided reconstruction represents a major step beyond older surgical options, which usually depend on destroying the affected part of the ear to relieve symptoms and often lead to partial loss of function, whereas the new method focuses on rebuilding the damaged area while preserving its natural role.

Experts at King Faisal Specialist Hospital and Research Centre state that the same digital modelling and micro-printing strategy could later be adapted to repair other hard-to-reach parts of the inner ear, offering more accurate options for patients with complex balance-related disorders and supporting the hospital’s precision medicine programme, which uses advanced imaging, digital design and customised implants matched to each patient’s anatomy.

The hospital notes that this work is consistent with its goal of being the preferred provider for highly specialised healthcare, and it highlights that King Faisal Specialist Hospital and Research Centre ranks first in the Middle East and Africa and fifteenth worldwide among 250 academic medical centres for 2025, while also being named the highest valued healthcare brand in Saudi Arabia and the region by Brand Finance 2024 and appearing in Newsweek’s lists of the World’s Best Hospitals 2025, the World’s Best Smart Hospitals 2026 and the World’s Best Specialized Hospitals 2026.
