Surgical Management of Trigeminal Neuralgia Emerging in the Long-Term after Cerebellopontine Angle Tumor Surgery without Tumor Regrowth

OBJECTIVES: Cerebellopontine angle tumors are reported causes of trigeminal neuralgia, but trigeminal neuralgia emerging long after cerebellopontine angle tumor removal, despite the absence of tumor regrowth, is extremely rare. Surgical resolution is required for intractable cases, but it is challenging due to the altered anatomy and severe adhesions from prior surgery, and unclear etiologies.

No actionable change for audiologists — this surgical management study is directed at neurosurgeons; audiologists should remain aware that patients with a history of cerebellopontine angle tumor surgery may report delayed-onset facial pain warranting neurosurgical referral.

Late-onset trigeminal neuralgia after cerebellopontine angle surgery is a poorly understood complication, and understanding its surgical management helps multidisciplinary teams provide better long-term follow-up for these patients.

1. 01Trigeminal neuralgia (severe episodic facial pain) can emerge years after cerebellopontine angle tumor surgery even without tumor regrowth.
2. 02Study investigates surgical treatment options for this delayed complication.
3. 03Published in Journal of Neurological Surgery Part B (2026); peer-reviewed.
4. 04Relevant to audiology mainly through shared patient population (acoustic neuroma / vestibular schwannoma survivors).
5. 05Audiologists should be aware of this late complication for appropriate long-term patient monitoring and referral.
