Abstract

Background: Funnel chest is one of the most common anomaly of chest wall, which is manifested by depression of sternum and costal cartilage. Popular operative methods were Ravitch operation and Wada operation. Material and Method: From 1983 to 1996, 21 cases of funnel chest were corrected surgically in the department of thoracic surgery, National Medical Center. Investigated age and sex distribution, combined anomaly,clinical symptom, degree of correction and complication, postoperative satisfaction. We used 2 different surgical methods, one was Wada & its variants(17 cases), the other was Ravitch and it variants(4 cases). Most of operative indications were cosmetic problems. Result: The pre-operative Welch index was 4.188, but this index decreased to 3.46 after the operations.(p=0.046) The degree of correction was higher in Wada & it variant operation than the modified Ravitch operation.(p=0.54) Their results were satisfactory in 20 patients, while unsatisfactory in 1 patient because of a k-wire fracture. There was no recurrence of chest wall depression or postoperative death during the OPD follow up period. Conclusion: We recommend Wada operation in symmetric and small degree of depressive chest wall deformity in preand post school age.

배경: 누두흉은 가장 흔한 흉골기형으로 대부분이 선천적으로 흉골과 그 주위의 연골을 포함한 늑골의 일부가 함몰한 기형을 말한다. 누두흉의 수술방법은 Ravitch 술식에 의한 흉골거상법과 Wada 술식에 의한 흉골반전법이 주로 시행되어 왔다. 대상 및 방법: 1983년 1월부터 1996년 12월까지 누두흉의 수술적 교정을 받은 21명을 분석하였다. 환자의 연령별 분포와 동반된 기형의 종류, 동반된 증상, 각 수술방법에 따른 교정의 정도와 합병증의 유무, 환자의 술후 만족도를 조사하였다. 수술적 방법으로는 Wada술을 17례, Ravitch 술식을 4례 실시하였다. 수술적 적응증은 미용상의 이유가 가장 많았다. 결과: 술전의 Welch index는 평균 4.188 이었고 술후 3.46으로 개선되었고 Wada 술식에서 교정도가 높았다.(P=0.046) 합병증의 빈도는 Ravitch 변형술에서 높았으나 통계적 유의성은 없었다.(P=0.54) 수술후 합병증을 보인 1례를 제외한 전례에서 환자의 만족도, 술전의 정신,신체적 결함에서 회복되었고 함몰의 교정 정도에서도 만족할만한 결과를 얻었다. 수술후 외래 추적 결과 누두흉의 재발과 사망례는 없었다. 결론: 학동기전후연령과 함몰이 대칭성인 누두흉인 경우에서 흉골반전술이 좋은 술식이 된다고 생각한다.
