Abstract

A free full-thickness chondrocutaneous flap from the auricular concha for the repair of large tracheal defects was transferred successfully. The flap is based on the superficial temporal vessels (reversed flow) and the posterior auricular vessels. The advantages of this flap for the repair of tracheal defects are (1) its dissection is easy, (2) thin components of the flap provide a wide postoperative airway, (3) the structure of the reconstructed trachea is made firm by the conchal cartilage with vascularization, (4) the highly vascularized cartilage results in less resorption than a free cartilage graft, (5) the donor site can be repaired easily and is concealed by the remnant auricle, and (6) a long arterial pedicle (reversed flow) can be obtained. The disadvantages are (1) there may be temporary postoperative congestion of the flap, (2) postoperative narrowing of the auriculocephalic sulcus may occur, and (3) a short venous pedicle often requires a vein graft.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.
