Purpose:
Classical trigeminal neuralgia with concomitant persistent facial pain responds poorly to conservative treatment. The authors describe the effects of microvascular decompression and radiofrequency thermocoagulation for patients with classical trigeminal neuralgia and concomitant persistent facial pain.
Case Report:
Case 1 was a 61-year-old man with dull, continuous, aching pain in the left maxillary and mandibular molar area. Case 2 was a 68-year-old woman with aching pain in the maxillary right molar. Case 3 was a 67-year-old woman with severe pain in the right upper lip and maxillary right second premolar. Case 4 was a 42-year-old man with orofacial pain of 14 months' duration. Cases 1 and 2 underwent radiofrequency thermocoagulation and reported good relief of symptoms. Cases 3 and 4 underwent microvascular decompression and attained excellent relief.
Conclusion:
Microvascular decompression may be more effective than radiofrequency thermocoagulation for patients with classical trigeminal neuralgia with concomitant persistent facial pain.
