Pectus excavatum: evaluation of Nuss technique by objective methods.

Area of Science:

• Thoracic Surgery
• Medical Device Technology
• Clinical Measurement

Background:

• Pectus excavatum (PEX) is the most common congenital anterior chest wall deformity.
• Objective classification of PEX anatomical distortion remains limited.
• Existing assessment methods may lack precision in quantifying deformity.

Purpose of the Study:

• To introduce two novel, objective clinical methods for evaluating PEX deformity: chest cyrtometry and an anthropometric index.
• To demonstrate the simplicity and applicability of these methods in an outpatient setting.
• To compare the efficacy of these new clinical methods against traditional radiological assessments.

Main Methods:

• Development and application of chest cyrtometry and an anthropometric index.
• Evaluation of 20 patients with PEX (undergoing Nuss procedure) and 40 healthy controls.
• Direct external measurement of chest wall deformity using the novel methods.

Main Results:

• The new clinical methods provide objective, direct external measurements of PEX deformity.
• Chest cyrtometry and anthropometric index were found to be more sensitive or precise than radiological methods.
• These methods offer a simple and easily applicable approach for office-based evaluation.

Conclusions:

• Chest cyrtometry and anthropometric index represent significant advancements in the objective clinical evaluation of Pectus excavatum.
• These novel methods offer superior precision compared to radiological assessments for quantifying chest wall deformities.
• The proposed techniques facilitate straightforward and reliable PEX assessment in clinical practice.
