Background:
Stereotactic radiosurgery (SRS) has recently gained space as an accepted non-invasive alternative treatment option for drug resistant Glossopharyngeal neuralgia (GPN). The purpose of this systematic review was to provide an overview of the outcomes of SRS treatment in patients with GPN.
Methods:
A literature review until March 2023 was performed. Data about patient's demographics, complications and recurrence rates, additional treatment post procedure as well as pain outcomes in the short and long term were collected. Studies without reported pain outcomes were excluded.
Results:
Sixteen studies with a total of 97 patients diagnosed with GPN who had undergone SRS were identified. The mean reported maximal radiation dose ranged from 70 to 88.7 Gy with the glossopharyngeal meatus (GPM) being the most common target in 12/16 studies. The median time from SRS till pain response was between 2 and 120 days. The mean proportion of patients requiring further treatment after SRS ranged from 11.1 to 57.14% in a time frame between 2 and 36 months post procedure. Favourable pain response rates after SRS (BNI-IIIb) ranged from 60% to 100% and 57.1%-100% in short and long term respectively.
Conclusion:
SRS for GPN remains a safe alternative to surgery with low complication rates and favourable pain outcomes in both short and long term.
