OBJECT: Trigeminal neuralgia (TGN) occurring after radiosurgical treatment of cerebellopontine or petroclival tumors may be very difficult to control. Our aim was to determine the efficacy of neurosurgical treatment in regards to pain control and to evaluate the procedure-related complication and morbidity rates.
METHODS: Retrospective study of a series of operated patients with radiosurgery-induced TGN. The primary goal of the surgery was to inspect and decompress the trigeminal nerve; the second goal was to remove the tumor remnant completely, if safely feasible. The main outcome measures were pain control, time to onset of pain relief and its duration, occurrence of new neurological deficits or worsening of the existing one and completeness of tumor removal.
RESULTS: The four patients met the inclusion criteria: 2 with vestibular schwannomas, 1 with petroclival meningioma and 1 with an epidermoid. TGN occurred 12-60 months after radiosurgery (mean 39 months). At presentation the pain attacks occurred multiple timesdaily and lasted from a few seconds to 2-3min. The Complete tumor removal via the retrosigmoid approach was achieved in all cases. There were no major operative complications or persistent morbidity, besides one patient with trochlear nerve palsy. All patients experienced immediate pain relief after surgery. At follow-up (median duration - 42.5 months) the three patients reported complete pain resolution. One patient had occasional slight pain but did not need any medications.
CONCLUSION: Surgery is safe and effective treatment option of patients with intractable radiosurgery-induced TGN. It leads to excellent pain control and is curative in regards to the neoplastic disease.
