Percutaneous Intercostal Cryoneuromodulation Onset Timing.

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.
