What is the purpose of a thoracoplasty?

The purpose of a thoracoplasty is to reshape the thoracic cavity, which is crucial for treating various conditions such as severe lung disease, spastic lung disease, or to eliminate the space that may be caused by lung resection or other pathologies. This surgical procedure involves removing one or more ribs, which can help to provide better lung deflation, improve respiratory mechanics, and manage complications arising from diseases that distort the chest's normal architecture.

By reshaping the thoracic cavity, thoracoplasty can enhance the overall functionality of the respiratory system and alleviate symptoms that compromise a patient’s ability to breathe effectively. The modification of the thoracic cavity can also assist in managing conditions that cause recurrent infections or in preparing the area for potential lung transplant by ensuring optimal space and environment for subsequent procedures.

The other options do not accurately reflect the purpose of thoracoplasty. While removing lung tissue or fibrous tissue might be part of other procedures related to lung disease, they do not define thoracoplasty itself. Similarly, the placement of drainage catheters pertains to managing fluid or air accumulation rather than reshaping the thoracic cavity.
