Brief summary
Percutaneous Intercostal Cryoneurolysis is a promising technique that addresses acute postoperative pain after Nuss procedure for pectus excavatum. However its onset timing has not yet been determined. A physical examination would assess the variation of chest skin sensitivity to soft touch, cold (water at 4°C), and heat (water at 40°C) through days following the cryoneurolysis procedure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| thermal sensitivity | one week (median) | Chest skin thermal sensitivity will be assessed through a thermofeel metal instrument set at two different temperatures: 15°C for cold sensation and 40°C for warm sensation. At least 4 different chest zones will be tested to discriminate potential differences. As a validated instument for chest skin thermal assessment does not exist, we will report only qualitative results, as normal impaired or absent sensitivity. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| chest skin sensitivity to touch | one week (median) | Chest skin mechanical sensitivity will be assessed through both validated von Frey filament testing, and cotton swab for soft touch. At least 4 different chest zones will be tested to discriminate potential differences. We will report qualitative results, as normal impaired or absent sensitivity. |
