Surgical management of petrous apex trigeminal nerve herniation causing trigeminal neuralgia with long-term outcome: illustrative case

Key Points

This study aims to explore the role of petrous apex trigeminal nerve herniation as a cause of trigeminal neuralgia and assess surgical efficacy.
Analyzed a rare case of trigeminal neuralgia associated with petrous apex complications.
Performed surgical intervention to address the herniation and alleviated symptoms.
Utilized imaging to evaluate the neurovascular anatomy related to the condition.
Surgical intervention led to significant symptom relief for the patient.
Case highlights the need for considering rare causes of trigeminal neuralgia in refractory cases.
Long-term follow-up showed sustained improvement in the patient's condition.

Abstract

To the best of the authors' knowledge, there are few reported cases of TN caused by PACs in the literature. This study highlights the importance of considering PACs as a rare but potentially reversible cause of TN, especially in patients with refractory symptoms whose imaging demonstrates no neurovascular conflict. Moreover, the effectiveness of surgical intervention in treating this condition is reinforced. https://thejns.org/doi/10.3171/CASE25460.
