[Indications and surgical technic for the correction of funnel chest and its results].

Treatment of funnel chest is only successful by surgical means. 425 funnel chest operations have been performed between 1956 and 1974 at the Surgical and Paediatric Surgical Department of the University Erlangen-Nürnberg. Different types of operative procedures have been compared with each other. The internal fixation of the elevated funnel chest with a metal strut is an operative procedure with the lowest infection rate, with less recurrences and the best anatomical and cosmetic results. The surgical procedure involves a double incision of the ribs parasternally and at the borderline of the funnel, the mobilised ventral part of the chest is elevated by a metal strut to an anatomically normal position. 235 patients have been operated on by this method. In 7% a local wound infection occured, there was one total recurrence and 15 partial recurrences. 4 years after operation 75% of the patients had an anatomically normal and well developed chest with an excellent cosmetic result.

[Effect of subtotal resection of costal cartilage on the basic chest dimensions in children with funnel chest deformity].

The paper summarizes the results of anthropometric and computed tomographic studies of the external and internal chest dimensions in 86 patients with Degree II-III infundibuliform chest deformity. Full resection of deformed cartilages of the third to seventh ribs has been examined for its impact. The children with infundibuliform chest deformity have been found to have an impressed anteroposterior dimension of the bilateral chest. The transversal and anteroposterior dimensions of the chest remain unchanged after removal of cartilages. The chest enlarges only sagittaly. One- and three-year follow-ups have indicated that full removal of the deformed cartilage has no impact on the growth of the chest.

Unusual combination of pulmonary sequestration and funnel chest.

Cases of pulmonary sequestration and cases of funnel chest are frequently accompanied by other anomalies, although the combination of pulmonary sequestration and funnel chest is rare. In this study, we report ten cases of pulmonary sequestration, nine of which had the combination of pulmonary sequestration and other anomalies; four evidenced the unusual combination of pulmonary sequestration and funnel chest.

Abnormalities, Multiple

[Funnel chest and pigeon breast (author's transl)].

The dominant heredity of funnel chest formation is considered proved. The incidence of funnel chest is about 0.05% of the population, with the emphasis on boys. In very many cases deformities of the anterior chest wall are associated with other deformities. All patients with pigeon breast or funnel chest suffer considerably psychically under their deformity. This is the main indication for operation. The best age for operation is from the 2nd to 6th years of life. Conservative methods of treatment are never successful. Of the present day operative techniques, the stabilizing--by implantation of metal clips--are opposed to the nonstabilizing operative procedures. Both achieve equally good and completely satisfactory results in 85% of cases.

[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.

[Surgical treatment of funnel chest. Surgical experience with 90 cases].

Funnel chest, a congenital hereditary deformity, may lead to impairment of cardio-pulmonary function. The predominant motives for operation are psychological and cosmetic. Minor deformities amenable to physiotherapy should not be operated on, but moderately severe one represent a justified surgical indication. Objective photographic documentation is essential. Because of their bearing on surgical technic and results the symmetrical, asymmetrical, localized and extensive deformities should be distinguished. 90 operations have been performed between 1951 and 1974 according to the different known technics published during that period. Results were irregular until the introduction, eight years ago, of an operation combining extensive resection, by the method of RAVITCH, and stabilization by a metal strut as recommended by ADKINS et al. 24 operations performed during the last eight years have afforded perfect long term results.

[Surgical treatment of funnel chest].

In 1976-1985, 39 patients were operated for the funnel chest. All patients were enrolled for the intensive rehabilitation program in the hospital, and correction exercises followed by swimming were recommended after release home. A favourable cosmetic effect was achieved in all patients in early postoperative period. However, a recurrence of the funnel chest has been noted in 10 patients (26%), later. Abnormality has been less advanced except 1 patient in whom subjective worsening has been noted.

[Surgical indications of funnel chest].

Pathological findings in ECG represent indications for operation only if they are accompanied by subjective complaints and psychogenic problems. The extent of the abnormality usually does not correlate with the patient's complaints. Disappearance of such complaints after surgery does not be considered as a sign of successful surgery. Even a deep funnel chest is not necessarily an indication for operation if the patient has no complaints and can manage the situation. A flat funnel chest should not be operated on. The operation can be performed in patients between 4 and 24 years of age. If severe associated anomalies require operation as well, the choice is not for correction of the funnel chest first.

[Funnel-chest and cardio-pericardial pathology, apropos of 2 cases treated by pericardioplasty and parietal remodelling].

Numerous pathogenic hypotheses were put forward to explain the Funnel Chest. It is possible that the origin of this malformation is not related to an involvement of the thoracic wall or the diaphragm, but rather to a negative pressure behind the sternum which is attracted by inspiratory movements, this resulting in, and aggravating the malformation. This negative pressure of the anterior mediastinum would result from an absent cardiac mass which was displaced leftward, favoured by an enlarged and flaccid pericardial sac. Haemodynamic examination of the subjects with a funnel chest has a two-fold interest: it provides the data for a physiopathologic study. Particularly the measurement of the right ventricular pressure which becomes negative on deep inspiration. On the other hand, it makes it possible to demonstrate the presence or the absence of any cardiac lesion combined with the deformity. The angiographic pictures demonstrate the distortion of the right ventricular chamber in particular, and the elongation of the inferior vena cava. Among the various classical treatments, some aim at cosmetic improvement, others at thoracic wall correction. However, the latter do not prevent recurrence in the child, and are too severe a procedure in the adult. This is why a new treatment is put forward, on the basis of the new pathogenic considerations: repositioning of the cardiac mass displaced leftward, after a pericardoplasty, combined with remodelling of the excavated thoracic wall. Thus cardiac reposition into the anterior mediastinum avoids a long-term recurrence of the deformity. In our experience, pericardioplasty combined with thoracic wall remodelling has given good results, both immediate and delayed, in the two cases in which it was performed. A longer series, particularly on the younger child, is necessary to form an opinion on the value of this procedure.

Adult

[Funnel chest operation and age (author's transl)].

Analysing 199 cases of funnel chest operations the following proposals are to be discussed: early operation of boys in a modified Ravitch-technique with transverse osteotomy of the anterior sternum-wall, resection of the xiphoid process and fastening of the perichondrium to the pectoral muscles. The cosmetic indication excludes a late operation. If any late operations are performed they should be considered only for girls. Stabilisers should be used only in case of later operations, recurrences and asymmetrical forms. No operation should be performed in case of genetic defects (malformationsyndrome, flat-chest and channel-chest). The therapeutic results should be made objective by means of the sagittal inner thorax-diameter after Stucki. The submammary incision should be omitted.

A vascularised rib strut technique for funnel chest correction.

We have refined the Ravitch technique of sternal elevation for surgical correction of funnel chest. Our major modification is introducing a living rib strut for supporting the elevated sternum. The left 5th rib with a vascular pedicle from the internal thoracic artery is turned 180 degrees beneath the sternum. We have used this method in 10 cases. The results have all been satisfactory.

Funnel Chest

[Funnel chest deformities: operative treatment (author's transl)].

The frequency of chest deformities is 1:100; operative treatment, however, is necessary in only 1:1000 patients with such a deformity. The most frequent deformity--in 91%--is the funnel chest. Chicken breast, combined types, and fissures of the sternum are seldom seen. Indications for operative treatment are: deformity of more than 25% of the normal sagittal diameter of the chest; heart failure and the degree of pathologic signs on the EKG; alterations of the vertebral column; psychologic aspects. Our operative procedure consists of double cartilage incision and stabilization of the chest with a metal strut.
