Background and aim
 
Scar neuromas and postherpetic neuralgia are usually very poorly responsive to conservative treatment. Cryoablation allows you to eliminate the cause of pain without fear of a new neuroma.

Materials and Methods: 
Treated 8 female patients: 4 with scars neuromas, 4-postherpetic neuralgia. History of pain from 3 to 10 years. Pain intensity VAS 7-9. Postherpetic neuralgia scars were greater than 2% of body surface. Received conservative treatment using NSAIDs, gabapentinoids,  antidepressants, opioids and lidocaine patches. The treatment had little or no efficiency. For all patients the pain was radiated far from the damaged. All patients had been subjected to the test block with 1% lidocaine to find out where and how deep is pain generator.
Based on the results of the test block, the cryoablation was performed by Metrum CryoFlex.
 
Results
In all patients three weeks after cryoablation, there was no pain (VAS 0-1) in the primary lesion area. For today the painless period is six and more months. Patients do not need medication, or the treatment is associated with other signs of chronic pain.
We have not seen any side effects or complications.

Conclusion
1. Cryoablation allows to treat patients in such situations where other methods are not available
2. Experience with this method is modest, literature limited.
3. Cryoablation deserves to be introduced and the material collected.
