In the absence of demonstrable functional impairment, pectus excavatum is merely a congenital deformity, albeit with a marked psychological impact. Many patients do not wish to undergo thoracic remodeling operations, which are invasive and do not clearly result in respiratory or cardiac improvement.
From 1993 to 2015, the authors designed 401 custom-made silicone implants to treat funnel chests. Before 2007, implants were made from plaster chest molds. Beginning in 2007, three-dimensional reconstructions were made from computed tomographic scans by computer-aided design. The authors prospectively recorded all assessments and follow-up data since 1993. Preoperative and postoperative photographs of two random groups of 50 patients were analyzed, in a blinded manner, by two surgeons independently. Intraoperative and postoperative complications, clinical outcomes, patient satisfaction, and quality of life were evaluated.
One infection and three hematomas were recorded. Periprosthetic seroma was evident in all cases. Patients rated the cosmetic outcomes of computer-aided design implants significantly higher than those of the earlier implants made using plaster molds (p = 0.030). Malformations were better corrected in the computer-aided design group (86 percent) than in the plaster group (72 percent) (p = 0.038). Patient satisfaction was higher in the former group (p = 0.011). Medical Outcomes Study 36-Item Short-Form Health Survey scores revealed significant improvements, both socially and emotionally.
Correction of pectus excavatum using a computer-aided design silicone implant fulfils aesthetic and psychological demands. The technique is simple and reliable and yields high-quality results. In the medium term, the approach may render invasive techniques obsolete. These operations remain risky and of doubtful functional utility.
