Although the NUSS technique has become the standard minimally invasive procedure for correcting this deformity, there is a lack of comparative data between the classic and modified NUSS techniques. This research aims to fill this gap by comparing these two methods in terms of various outcomes, such as operative time, postoperative pain control, length of stay in the intensive care unit, and overall cosmetic results.

This study addresses the need to optimize surgical techniques to improve patient outcomes. By evaluating these two approaches, the research seeks to provide insights that could lead to better management strategies for patients with pectus excavatum, potentially influencing future clinical practices.

Inclusion Criteria:

• Patients aged 11 to 18 years.
• Patients who underwent surgery between 2010 and 2024 using either the classic or modified Nuss technique. - Patient with a Haller index of 2.25 or higher.

Exclusion Criteria:

• Patients with a Haller score below 2.25.
• Patients who have undergone surgery using alternative techniques such as Ravitch or modified Ravitch.
• Patients under 11 years of age or over 19 years of age.
