“…Cohen et al [ 10 ] reported that PRFT has repeatedly been demonstrated as a safe and effective procedure, even in instances where other treatment modalities have failed. Its use in a variety of conditions demonstrates the attractiveness of PRFT as a less invasive alternative to surgical intervention that may involve significant morbidity [ 11 ]. Microstructure research has indicated that PRF causes axonal changes more obviously in C fibers than that in Aα or Aβ fibers, which is largely manifested within the mitochondria as micro-cytoskeletal edema, leading to an abnormality in ATP metabolism and ion channel and pump function, thereby blocking the pain transfer in relevant nerves [ 12 ].…”

Postherpetic neuralgia (PHN) is one of the most difficult pain syndromes to treat. Invasive treatments may be considered when patients fail to obtain adequate pain relief from noninvasive treatment approaches. Here, we present three cases of PHN in the mandibular branch treated with ultrasound-assisted mental nerve block and pulsed radiofrequency treatment. None of the patients had adequate pain relief from the medical therapy, so we performed the mental nerve block on the affected side under ultrasound assistance. Two patients showed satisfactory pain relief continuously over 12 months without any further interventions, whereas one patient only had short-term pain relief. For the patient had short-term pain relief we performed pulsed radiofrequency treatment (PRFT) on the left mental nerve under ultrasound assistance. After PRFT, the patient had adequate pain relief for 6 months and there was no need for further management. (Korean J Pain 2014; 27: 81-85)

“…However, it is an invasive procedure that can lead to severe complications and is contraindicated for elderly individuals, patients with severe systemic diseases and patients whose symptoms are not caused by vascular compression. It is therefore not the therapy of first choice in most cases 9 . Botulinum toxin type A (BTX-A) has been used to treat HFS since the 1980s and provides symptom relief and improved quality of life in about 85% to 95% of cases 10 .…”

Hemifacial spasm (HFS) is a craniofacial movement disorder characterized by involuntary contractions of the muscles on one side of the face 1 . The most common site for the contractures is the orbicularis oculi muscle, but the corrugator supercilii, frontalis muscle, orbicularis oris, zygomaticus major and platysma can also be affected 2 . The condition is believed to be mainly due to a peripheral dysfunction of the facial nerve, occasionally associated with nerve compression by a blood vessel or tumor 3,4 . The pathophysiology, however, has yet to be fully elucidated as the condition can occur in the absence of structural alterations 3 . In a recent study, Wilkinson and Kaufmann 5 showed that HFS may be associated with central nervous system changes. Accordingly, one previous study from our group found similar profiles of obsessive and psychiatric symptoms in cases of HFS and blepharospasm, which is recognized as a movement disorders of A total of 550 BTX-A injections were administered to 100 HFS patients. Results: Mean duration of improvement following each injection session was 3.1 months, mean latency to detection of improvement was 7.1 days and mean success rate was 94.7%. Patients were evaluated at an interval of 5.8 months after each application. Adverse effects, which were mostly minor, were observed in 37% of the patients at least once during follow-up. The most frequent was ptosis (35.1%). Conclusion: Treatment of HFS with BTX-A was effective, sustainable and safe and had minimal, well-tolerated side effects.

“…A recent report showed that fluoroscope-guided facial nerve block and pulsed radiofrequency treatment might be effective for patients with recurrent facial spasm. [ 7 ] Further studies addressing the selection of appropriate prosthetic materials in microvascular decompression are needed, involving multiple centers and long-term observation of patients after initially successful decompression surgeries.…”

Background:The effectiveness of microvascular decompression in treating hemifacial spasm is widely accepted. However, some experience recurrence of hemifacial spasm after successful decompression surgery. Especially, delayed recurrence more than 5 years after surgery is rare and the cause of this phenomenon is unknown.Case Description:A female underwent microvascular decompression to treat her hemifacial spasm 6 years ago. Six years later, her hemifacial spasm recurred and she underwent a second surgery. The second surgery revealed that the sponge had become fragile, losing the ability to absorb the impact of pulsatile compression of the offending artery on the root exit zone of her facial nerve.Conclusion:We report a case in which degeneration of material, a sponge (polyurethane), used in decompression surgery caused delayed recurrence of hemifacial spasm. The selection of appropriate prosthetic materials is essential in such functional surgeries.
