title: The seagull wing self retaining prosthesis in the surgical treatment of pectus excavatum.
abstract: BACKGROUND
  Between June 1958 and June 1996 we operated many patients affected by pectus excavatum with an original surgical technique. In this study we evaluated the durability of the results.
  
  
  METHODS
  
  
  
  METHODS
  Retrospective study with a mean follow-up time of 15.8 years/pt, and 60% complete.
  
  
  METHODS
  private and institutional practice.
  
  
  METHODS
  357 patients (253 males and 104 females, mean age = 18.2+/-5.1 years) affected by pectus excavatum. The grade of PE (Chin classification) was I in 76 patients, II in 165 and III in the remaining 116. Most of the patients required operation for aesthetic reasons only (339 patients; 95%).
  
  
  METHODS
  the surgical technique consisted of a double transversal sternotomy at the level of the lowest and highest part of the depression associated with a longitudinal sternotomy. A wedge resection of the ribs was then performed and the sternum was fixed using an original stainless steel strut prosthesis moulded into a seagull wing. The strut was removed 12 months postimplantation.
  
  
  RESULTS
  There were no operative deaths. Four patients (1.2%) had sternal wound infection, which was successfully treated. From the aesthetic point of view, the postoperative results were excellent in 262 patients (73.4%), good in 82 (22.9%) and poor in 13 (3.6%). All subjective symptoms, when present, disappeared after surgery.
  
  
  CONCLUSIONS
  The seagull wing prosthesis appears to be safe, easy to implant and to remove, and comfortable for the patient. This technique has shown good long-term results independently of type of deformity and patient age.
