[Techniques and experiences in funnel chest operations].

Hegemann's technique of funnel chest correction using transsternal metal bar stabilization was adapted from the method published by Sulamaa and coworkers in 1958. Until the end of 1991, about 2400 chest wall corrections were performed in our department, more than 2000 of them using modifications of the original method. The principles of external chest wall measurement, our classification method, and the current operative modifications are described. In long-term follow-up examinations less than 3% recurrences should be possible.
