Non-invasive treatment of pterygopalatine fossa schwannoma with gamma knife radiosurgery.

BACKGROUND

Surgical resection for pterygopalatine fossa schwannomas can be challenging due to the complex anatomy and potential morbidity. Gamma knife radiosurgery (GKRS) offers a minimally invasive alternative with precise targeting and minimal damage to surrounding structures.

CASE REPORT: A 21-year-old female patient who had a history of progressive left-sided facial numbness over the past year and was diagnosed with progressive pterygopalatine fossa schwannoma underwent gamma knife radiosurgery. The radiological and clinical outcomes of the patient were evaluated over a period of 15 years, with the patient remaining symptom-free and experiencing no adverse effects from the treatment.

CONCLUSION

The patient's positive outcome, with significant tumour reduction and symptom relief, underscores the potential of this non-invasive technique as a primary treatment modality for schwannomas in challenging anatomical locations.
