Introduction
A funnel chest (pectus excavatum or funnel chest) is a congenital malformation of the thorax. The sternum stands too far inwards and a funnel-shaped retraction of the ribcage occurs. In most cases a funnel chest has only cosmetic disadvantages. Since the retraction of the ribcage can result in less space for the heart and lungs, the funnel chest may require treatment. Besides respiratory gymnastics, physiotherapy and surgical measures, the suction cup can be considered as a non-surgical therapy option.
How does the suction bell work with a funnel chest?
The treatment with the suction bell according to Klobe and Schier is suitable for patients in whom the funnel chest is not very pronounced and above all has a cosmetic disadvantage. This method of treatment is particularly preferred for children and adolescents, since the still soft bone and cartilage structure of the chest wall means that a successful treatment can be expected. The suction cup is a vacuum pump made of orthopedic silicone.
It is attached to the outer, front thorax. The vacuum pump then creates a negative pressure. This negative pressure should then ensure that the inwardly inclined thorax is set up.
In order to avoid pain or circulatory problems, the first treatments should be performed in a clinic under supervision. The negative pressure of the suction bell is no more than 15% below atmospheric pressure, so that major skin damage is unlikely. Skin irritation may occur due to the negative pressure. In addition to the suction cup, physiotherapy and muscle building training should definitely be carried out in order to positively support the vacuum therapy.
What results can be expected?
After about three months the first treatment successes are achieved. After about half a year there are lasting successes, which means that the funnel chest does not fall back into its original position. To maintain the success of the therapy, the therapy must be continued for another two years.
Good results can be expected especially in children and adolescents. To what extent the chest wall will eventually rise cannot be predicted exactly. To achieve the best possible results, a consistent muscle build-up and posture training should be carried out to support the suction bell treatment.
