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.
