Patients who underwent percutaneous cryoneurolysis for the Nuss procedure pain management
All patients who underwent surgical correction of pectus excavatum via the Nuss procedure between July 1, 2022 and February 28, 2026 are considered eligible for enrollment. Additionally, for the prospective component, patients scheduled for surgery up to December 31, 2026 at the Pediatric Surgery department of our institution will be considered eligible. Inclusion criteria: Age greater than 14 years. Patients who underwent percutaneous cryoneurolysis. Patients who underwent surgical correction of pectus excavatum according to the Nuss procedure. Patients who withhold consent to participate in the study, patients with pre-existing neurological conditions, and patients who do not attend the scheduled follow-up visits will be excluded from the study. |
Assessment tools include validated questionnaires (S-LANSS and PedsQL) and a structured physical examination of thoracic sensitivity.
These tools are administered at pre-specified follow-up appointments (timepoints).
The sensory physical examination is conducted using four standardized stimuli, selected to systematically assess each class of afferent nerve fibers of the intercostal nerves.
For cold thermal sensation (Aδ fibers), a latex glove containing an ice-water mixture (4-10°C) is applied in contact with the skin over predetermined anterior thoracic areas.
For warm thermal sensation (unmyelinated C fibers), an analogous container filled with water at approximately 40°C, heated using a bottle warmer, is employed.
Tactile sensitivity (Aβ fibers) is assessed using a standardized camel-hair neurological brush for light touch, and Von Frey filaments (5.07/10 grams) for pressure sensitivity.

CPSP assessment
기간: The same patients are followed across multiple timepoints (1, 3, 6, 12, 24 months), allowing to track how chronic pain evolve over time.
|
To describe the incidence of chronic postoperative pain, defined as persistence of pain beyond one month, according to two parameters: direct measurement using the validated pain assessment scale for adolescent and young adult patients (NRS scale), and indirect measurement through the consumption of analgesic medications included in the institutional current protocol (acetaminophen and NSAIDs).
|
The same patients are followed across multiple timepoints (1, 3, 6, 12, 24 months), allowing to track how chronic pain evolve over time.

sensitivity recovery
기간: The same patients are assessed across multiple timepoints (1, 3, 6, 12, 24 months), allowing to track how sensitivity recovery evolve over time.
|
To describe the evolution of thoracic thermotactile hypoesthesia over time, starting from the day of cryoneurolysis.
|
The same patients are assessed across multiple timepoints (1, 3, 6, 12, 24 months), allowing to track how sensitivity recovery evolve over time.
