Abstract:

Objective

To explore the diagnostic and therapeutic strategies for secondary trigeminal neuralgia (STN).

Methods

The clinical data of 34 STN cases admitted to our hospital from January 2017 to March 2022 were retrospectively analyzed in combination with the relevant literature.

Results

All the 34 cases of STN were caused by space-occupying lesions. All patients received surgical treatment; total excision was achieved in 31 cases, and subtotal excision achieved in 3. Ten cases were found with vascular compression of the trigeminal nerve during operation and underwent microvascular decompression. Postoperatively, pain disappeared in 33 cases and was significantly relieved in 1.

Conclusions

Space-occupying lesions in the CPA area is the primary cause of STN, and classic trigeminal neuralgia may coexist. CT and MRI of the head are essential for STN diagnosis. Surgery is the first choice of treatment for STN. Attention should be paid to vascular compression intraoperatively.

Key words: Secondary trigeminal neuralgia, Space-occupying lesions, Diagnosis, Treatment strategy
