Surgical Procedure Benefits

When comparing the Nuss Procedure to older “open” surgical options, there are several benefits of the procedure’s less invasive method.

The primary benefits include a shorter operating time, less blood loss, and smaller, less visible incisions.1 Some clinical data also suggests that because no cartilage or pieces of rib are being removed during the procedure, the patient’s chest and rib cage will be able to grow and repair itself in a natural manner.2 The combined effect of these benefits means that a patient’s body is subjected to less trauma compared to other open surgery options. The Nuss Procedure is a widely-accepted effective method for treating pectus excavatum.2

Lung Function Matters

Research focusing on the Nuss Procedure indicates that post-operative patients, who have had the bar(s) removed, show significant improvement in lung capacity as tested by “Forced Expiratory Volume in 1 Second” or FEV1. This data suggests that these patients have  similar or equivalent lung function to healthy individuals with no history of Pectus Excavatum. 3,4,5,6,7 This demonstrates that a patient’s lungs may be able to transfer more air and function more efficiently following treatment with the Nuss Procedure and removal of the Pectus Support Bar.8

Improved or higher FEV1 values indicate that a patient’s lungs are able to move more air more efficiently, contributing to a healthy pulmonary system. 

Heart Function Matters4

Healthcare professionals use function tests to evaluate how well (or poorly) certain organs are working within the body. The results of function tests are always compared to a “reference range” which is a range of values that would be observed in healthy people of similar age, sex, race, etc. to the patient. Heart function is evaluated in this way.

Data shows that surgical correction of Pectus excavatum can improve specific heart function values. This means that:

  • The values may be within the reference range when they were not before surgery or
  • The values are closer to the reference range than before surgery.

Specific tests to measure heart function:

  • Improved “Maximum Cardiac Index” which is a measure of how well the heart performs compared to the size of the patient1,2
  • Improved “Stroke Index” which is a measure how efficiently a patient’s heart pumps blood4,6
  • Increased “Oxygen Pulse” which is a measure of the amount of oxygen delivered to the bloodstream during each heartbeat while the patient is resting4,6

All of the above measurements contribute to improved heart and lung function. Benefits of improved cardiopulmonary function might include more stamina during exercise, not tiring as quickly, and the ability to participate in sports for a longer period of time than was possible before the corrective procedure.9

Recurrence Rate Matters

When considering a corrective surgery,  many patients are concerned that their deformity will reoccur. Published data evaluating the success rate of the Nuss procedure, indicates that recurrence is reported in less than 2% of cases.10, 11, 12,12, 14, 15, 16 A high probability of successful deformity correction and a low chance of recurrence is a significant benefit of the Nuss Procedure.

Quality of Life Matters

Aside from the potential physical benefits of the Nuss Procedure, surgeons may assert  that humanistic or quality-of-life measures such as “satisfaction with appearance” and “increased confidence after surgery” should also be considered when evaluating the success of the surgery.17,18 Some of the more common aspects of humanistic outcomes include:

  • Confidence towards change of appearance after surgery
  • Better body feeling after surgery
  • Better self-acceptance after surgery
  • General satisfaction
  • General interest in sports
  • Higher self-confidence after surgery
  • Being more sociable after surgery

The response data in clinical research shows that patient satisfaction after surgery is high and approximately 82% of parents believe their child to be “satisfied” or “very satisfied” with the results.  These results indicate that the likelihood of a patient being satisfied with the results of the Nuss Procedure, barring complications, is high.18,19
