How long does funnel chest surgery take?

Pectus excavatum is a congenital chest wall deformity characterized by inward depression of the lower sternum, giving the chest a funnel-like appearance when viewed from above. Surgical correction can improve cosmetic appearance, relieve compression on the heart and lungs, and enhance cardiopulmonary function. So, how long does pectus excavatum surgery take? Below, we address this question.

How Long Does Pectus Excavatum Surgery Take?

Pectus excavatum surgery typically lasts about one hour; experienced surgeons may complete the procedure in approximately 30 minutes. The operation involves making two incisions on the chest wall, through which a Nuss bar (a curved stainless-steel implant) is inserted to support and elevate the depressed sternum at its lowest point. The bar remains implanted for at least two years to allow bony remodeling. During correction, overcorrection—resulting in pectus carinatum (pigeon chest)—may occasionally occur; however, such overcorrection is usually mild. Although there is a physiological lower limit to sternal depression, excessive elevation is undesirable cosmetically—even though it generally does not compress intrathoracic organs.

Currently, pectus excavatum surgery is performed under thoracoscopy or laparoscopy, enabling real-time visualization and protection of the pericardium. Inexperienced operators risk inadvertent pericardial injury; therefore, utmost caution is essential. Overall, modern surgical management of pectus excavatum is relatively straightforward, minimally invasive, and associated with rapid postoperative recovery. Patients must avoid excessive pressure or trauma to the chest during convalescence.

Prior to surgery, comprehensive evaluation of the child’s cardiopulmonary function is mandatory—including assessment for active respiratory infections such as pneumonia or bronchitis. Coagulation profiles, liver function tests, and routine blood chemistry panels must also be obtained and confirmed normal before proceeding with surgery.

During surgery—particularly when inserting the Nuss bar beneath the sternum—careful attention must be paid to avoid injuring the pericardium, lungs, or major thoracic vessels. All critical steps are performed under direct thoracoscopic visualization, ensuring procedural safety. Following surgery, close monitoring for complications—including pneumothorax and wound hemorrhage—is essential. Typically, patients remain in the intensive care unit for 24 hours for continuous observation; only after confirming hemodynamic and respiratory stability are they transferred to a general ward. Thus, both the surgical procedure and early postoperative period are considered safe.

The above outlines the typical duration and key considerations for pectus excavatum surgery. We hope this information is helpful to you.
