Four-layer technique for tracheostomy scar treatment.
Arch Craniofac Surg
June 2024
Department of Plastic and Reconstructive Surgery, Jeju National University College of Medicine, Jeju, Korea.
One important complication of the tracheostomy procedure is the depressed scar left after the tube is removed. A depressed tracheostomy scar can be aesthetically and functionally unacceptable. Tracheostomy scar treatment aims to fill lost soft tissue volume and correct tracheal skin tug.

Tracheobronchomalacia (TBM) occurs due to the weakening of cartilaginous part of the trachea, resulting in compromised airway function and leading to symptoms such as dyspnea, cough, and inability to clear secretions. Bronchiolitis obliterans syndrome (BOS) is the most prevalent late noninfectious pulmonary complication in patients who underwent allogeneic haematopoietic stem cell transplantation (HSCT). Therefore, patients experiencing progressive dyspnea and chronic cough after allogenic HSCT, with new obstructive pattern on pulmonary function test, are typically diagnosed with post-transplant BOS.

Trials
November 2023
Department of Anesthesiology, The First Hospital of China Medical University, 155 Nanjing North Street, Heping District, Shenyang City, Liaoning Province, China.
Background: Both acute normovolumic hemodilution (ANH) and autologous platelet-rich plasma (aPRP) have been demonstrated blood-protective effects in cardiac aortic surgery; however, the efficacies of the two methods have not been compared. This study aims to compare the effects of aPRP and ANH prior to aortic surgery on postoperative bleed and other outcomes.
Methods And Analysis: This is a prospective, single-center, double-blind controlled clinical trial including 160 patients randomized 1:1 to receive aPRP (test group) or autologous whole blood (ANH, control group).

In November/December 1978, the first successful tracheal transplantation in humans was performed at the University ENT Clinic in Cologne by the then senior physicians Kurt G. Rose (later chief physician in Dortmund) and Klaus Sesterhenn (later chief physician in Duisburg). Director of the clinic at that time was Prof.

Plast Reconstr Surg
May 2024
From the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College.
Background: Dense cartilaginous extracellular matrix makes decellularization and repopulation of tracheal cartilage difficult. However, the dense matrix isolates cartilaginous antigens from the recipient's immune system. Therefore, allorejection may be avoided by removing antigens from noncartilaginous tissues.
