100% Nerve Preservation: How Tongji Hospital Removes Brain Tumors Without Sacrificing Hearing or Facial Function
The Tumor Was Bleeding Inside His Brain — and the Clock Was Ticking
When 35-year-old Mr. Hu noticed his right ear gradually losing hearing and a persistent ringing that wouldn't stop, he assumed it was stress. An MRI told a different story: a mass in the right cerebellopontine angle — the narrow space between the brainstem and cerebellum where critical nerves pass through.
The diagnosis: acoustic neuroma (vestibular schwannoma) — a tumor growing on the vestibular nerve, compressing the hearing nerve and facial nerve beside it.
Then things got worse. After admission to Tongji Hospital (Huazhong University of Science and Technology), the tumor hemorrhaged spontaneously — sudden bleeding inside an already dangerous mass, dramatically increasing pressure on the surrounding brain structures and nerves.
What had been an urgent case became an emergency.

Why Acoustic Neuroma Surgery Is So Feared
Acoustic neuromas are technically benign — they don't metastasize. But their location makes them among the most dangerous tumors to remove. The tumor sits in intimate contact with structures that control some of the most important functions in daily life:
| Structure at Risk | Function | Consequence of Damage |
|---|---|---|
| Facial nerve (CN VII) | Controls all facial muscles | Permanent facial paralysis — inability to close the eye, smile, or eat normally |
| Cochlear nerve (CN VIII) | Transmits sound signals to the brain | Permanent deafness in the affected ear |
| Brainstem | Controls breathing, heart rate, consciousness | Life-threatening complications |
| Cerebellum | Balance and coordination | Chronic dizziness, inability to walk straight |
At most hospitals worldwide, patients are warned before surgery: "We will try to save the nerve, but we cannot guarantee it." Facial paralysis rates after acoustic neuroma surgery range from 10-50% depending on tumor size and the surgeon's experience. Hearing preservation is even less reliable.
The hemorrhage inside Mr. Hu's tumor made everything harder — the bleeding distorted the anatomy, obscured surgical landmarks, and made the nerve fibers even more fragile.
The Tongji Technique: Sub-Fascicular Microsurgery
Professor Shu Kai, Director of Neurosurgery at Tongji Hospital, led the surgical team using a technique called sub-fascicular (束膜下) microsurgical dissection — an approach that operates beneath the nerve's outer sheath rather than peeling the tumor away from the nerve surface.
Why this matters:
In traditional acoustic neuroma surgery, the surgeon works along the interface between tumor and nerve, gradually separating them. The problem is that the tumor often adheres tightly to nerve fibers, and forceful separation can stretch, tear, or devascularize the nerve — even if it appears anatomically intact afterward.
The sub-fascicular approach is fundamentally different:
- Enter beneath the nerve sheath — The surgeon identifies the plane between the tumor capsule and the nerve's fascicular bundles
- Dissect within this natural plane — Under high-powered microscopic magnification, the tumor is separated from the nerve fibers without disrupting the fascicles themselves
- Preserve the nerve's blood supply — By staying in the sub-fascicular plane, the tiny blood vessels feeding the nerve are protected
- Complete tumor removal — The entire tumor is excised without leaving residual fragments that could regrow
The result for Mr. Hu: complete tumor removal (3 × 2.4 cm) with both facial nerve and hearing function fully preserved.
Tongji Hospital's Track Record
This case wasn't an outlier. Tongji Hospital has established a dedicated Acoustic Neuroma Disease Center with remarkable institutional outcomes:
| Metric | Tongji Hospital | Global Average |
|---|---|---|
| Annual acoustic neuroma surgeries | ~400 cases | Most centers: 20-50 cases |
| Facial nerve anatomical preservation | 100% | 70-90% |
| Hearing preservation improvement | +15 percentage points above baseline | Varies widely |
| Surgical approach | Sub-fascicular microsurgery | Standard microsurgery or radiosurgery |
400 cases per year makes Tongji one of the highest-volume acoustic neuroma centers in the world — and surgical volume directly correlates with outcomes in complex neurosurgery.

Why Volume Matters in Acoustic Neuroma Surgery
Research consistently shows that acoustic neuroma outcomes are dramatically better at high-volume centers:
- Surgeons who perform 20+ cases/year have significantly lower complication rates than those doing fewer than 10
- Facial nerve preservation rates improve with each incremental case a surgeon performs
- High-volume centers develop institutional expertise — specialized anesthesia protocols, intraoperative nerve monitoring teams, and post-operative care pathways
At ~400 cases annually, Tongji Hospital operates in a tier that very few centers globally can match.
Acoustic Neuroma Surgery Cost: China vs Western Countries
| Procedure | China (Tongji Hospital) | United States | Germany |
|---|---|---|---|
| Microsurgical tumor removal | $12,000 - $22,000 | $50,000 - $120,000 | $30,000 - $60,000 |
| Stereotactic radiosurgery (Gamma Knife) | $5,000 - $10,000 | $25,000 - $50,000 | $15,000 - $30,000 |
| Neuro-ICU (per day) | $500 - $1,000 | $5,000 - $15,000 | $3,000 - $8,000 |
| Post-op MRI follow-up | $300 - $500 | $2,000 - $5,000 | $800 - $1,500 |
China prices include surgery, hospital stay, intraoperative nerve monitoring, and post-operative imaging.
Who Should Consider Acoustic Neuroma Treatment in China?
This level of neurosurgical care is relevant for patients with:
- Newly diagnosed acoustic neuroma — Especially tumors >2 cm where microsurgery is preferred over radiosurgery
- Growing tumors on watch-and-wait — When observation is no longer appropriate and intervention is needed
- Bilateral acoustic neuromas (NF2) — Where nerve preservation is critical for maintaining any remaining hearing
- Failed radiosurgery — Tumors that continued growing after Gamma Knife treatment
- Patients prioritizing nerve preservation — Those for whom hearing loss or facial paralysis would be professionally or personally devastating

Frequently Asked Questions
What are the symptoms of acoustic neuroma?
The most common early symptom is gradual hearing loss in one ear, often accompanied by tinnitus (ringing). As the tumor grows, patients may experience balance problems, facial numbness, and in severe cases, facial weakness. Any unexplained one-sided hearing loss should be evaluated with an MRI.
Surgery vs. Gamma Knife — which is better?
For small tumors (<2 cm), both are viable options. For larger tumors, microsurgery is generally preferred because radiosurgery cannot decompress the brainstem. At Tongji Hospital, Professor Shu Kai's team achieves nerve preservation rates that make microsurgery the preferred choice even for moderate-sized tumors.
How long is recovery after acoustic neuroma surgery?
Most patients are mobile within 2-3 days after surgery. Hospital stay is typically 7-10 days. Full recovery takes 4-6 weeks, during which balance may gradually improve. Flying is usually safe 2-3 weeks after surgery.
