The flap allows for 1) passive drainage of the pleural space and 2) negative pressure to develop in the thoracic cavity due to it being easier for air to escape than to enter the chest. The lung can then expand to the chest wall and seal the inner opening of the flap. [3] Other surgeons have subsequently proposed modifications to the procedure. [6]
Flap surgery is a technique in plastic and reconstructive surgery where tissue with an intact blood supply is lifted from a donor site and moved to a recipient site. Flaps are distinct from grafts, which do not have an intact blood supply and relies on the growth of new blood vessels. Flaps are done to fill a defect such as a wound resulting ...
The perfusion of the paramedian forehead flap comes from three sources: randomly, through the frontalis muscle and through the supratrochlear artery. [1] Because the forehead flap is an axial flap with a pedicle containing its dominant vessel, the pedicle can safely be narrowed to 1 to 1.2 cm. [1]
Research has found that pharyngeal flap surgery has been most effective for those with a sagittal closure pattern (good lateral wall movement but poor velar movement (Armour et al., 2005)). Pharyngeal flap surgery is not recommended for everyone and alternative treatment methods are available. One alternative is the use of a prosthesis. In some ...
The surgical procedure involves closure of the nasal cavity affected with atrophic rhinitis by creating mucocutaneous flaps. [3] These flaps are sutured together in two layers: first the mucosal layer, then the skin layer. The nasal cavity is kept closed for a period of 6 months/each; then an examination is done - if the crusts have disappeared ...

By using the patient’s own appendix for the procedure, doctors can avoid using artificial devices which can be seen and can cause the patient irritation. [1] If the appendix was previously removed or is unusable, a neoappendix can be created with a cecal flap. [2] A. Button device in the cecum via the appendix. B.
