OBJECTIVES: To study the role of bronchoscopy in slide tracheoplasty. METHODS: A retrospective analysis was conducted on the diagnosis and treatment of four children with tracheal stenosis admitted to Hunan Provincial People's Hospital from 2017 to 2020. The role of bronchoscopy was summarized in the preoperative evaluation, intraoperative positioning and measurement, and postoperative wound evaluation and treatment during slide tracheoplasty. RESULTS: Bronchoscopy evaluation before slide tracheoplasty showed that 3 of the 4 children had complete trachea rings, 2 had pulmonary artery sling, and 2 had multiple stenosis. Slide tracheoplasty was performed in the hospital on 3 children, and the midpoint of the stenosis segment was judged under bronchoscopy, and the length of the stenosis segment was measured, which assisted in the resection of the stenosis segment of the trachea. The pathogens were identified by lavage after the surgery. One child who developed scar traction 9 months after slide tracheoplasty in another hospital was improved by interventional treatment under bronchoscopy. Mucosal changes were found under bronchoscopy in 2 children 4 days after surgery, and the treatment plan was adjusted. One month after surgery, 2 children had granulation hyperplasia, which was improved by cryotherapy under bronchoscopy. One child abandoned treatment due to anastomotic necrosis and died. Three survivors were followed up for over 6 months with good prognosis, but all had tracheobronchial malacia. CONCLUSIONS Bronchoscopy can be used for the management of slide tracheoplasty in children with tracheal stenosis, which is helpful to postoperative rehabilitation and follow-up.

Epstein-Barr virus (EBV), a double-stranded DNA virus with an envelope, is a ubiquitous pathogen that is prevalent in humans, although most people who contract it do not develop symptoms (Kerr, 2019). While the primary cells EBV attacks are epithelial cells and B lymphocytes, its target range expands to a variety of cell types in immunodeficient hosts. Serological change occurs in 90% of infected patients. Therefore, immunoglobulin M (IgM) and IgG, serologically reactive to viral capsid antigens, are reliable biomarkers for the detection of acute and chronic EBV infections (Cohen, 2000). Symptoms of EBV infection vary according to age and immune status. Young patients with primary infection may present with infectious mononucleosis; there is a typical triad of symptoms including fever, angina, and lymphadenectasis (Houen and Trier, 2021). In immunocompromised patients, response after EBV infection may be atypical, with unexplained fever. The nucleic acid of EBV can be detected to confirm whether high-risk patients are infected (Smets et al., 2000). EBV is also associated with the occurrence of certain tumors (such as lymphoma and nasopharyngeal carcinoma) because it transforms host cells (Shannon-Lowe et al., 2017; Tsao et al., 2017).

OBJECTIVE: To observe the anatomical features and relative position of the brachiocephalic trunk and the trachea to provide an anatomical basis for diagnosis and treatment of mechanical airway obstruction and for facilitating the performance of tracheotomy. METHODS: A total of 91 formalin- fixed adult cadavers (70 male and 21 female) were used in this study. The whole length of the larynx and the trachea were separated and exposed from the neck to the chest, followed by separation of the aortic arch and its 3 branches to observe the anatomical position of the brachiocephalic trunk and the trachea. RESULTS: The brachiocephalic trunk and the trachea did not intersect in 3.30%, partially intersected in 71.43%, and completely intersected in 25.27% of the 91 cadaveric specimens. The male specimens all showed greater outer diameter of the aortic arch, the brachiocephalic trunk and the trachea with a greater length of the trachea than the female specimens (P < 0.05), while the distances from the aortic arch to the brachiocephalic trunk or the cricoid cartilage did not differ significantly between them (P > 0.05). The number of the tracheal cartilage rings above the brachiocephalic trunk ranged from 3 to 10, and the mean number did not differ significantly between the male and female specimens (P > 0.05). CONCLUSION The brachiocephalic trunk has complex anatomical relationship with the trachea, and caution should be taken to avoid injuries of the brachiocephalic trunk and the aortic arch in the diagnosis and treatment of mechanical respiratory obstruction and during tracheotomy.

The pediatric total facial management refers to a series of diagnosis and treatment processes to achieve the healthy development of the face through reasonable medical intervention. The main reason for the poor treatment effect is that the first contact doctor is limited to his own disciplinary analysis and treatment. The importance of multidisciplinary cooperation in the diagnosis and treatment of facial dysplasia in children has become increasingly prominent. it is necessary to comprehensively analyze and find the pathogenic factors of patients and formulate a comprehensive treatment plan to restore normal upper airway structure and nasal breathing, and then reshape the healthy craniomaxillofacial tissue structure, and the monitoring of the results of medical intervention should accompany the whole process of children's growth and development. This paper summarizes the current situation of the treatment of children with facial dysplasia and puts forward the concept of orderly individualized multi-disciplinary diagnosis and treatment of pediatric oral maxillofacial management.

Inflammatory myofibroblastic tumor is a rare tumor of mesenchymal origin. A case of intratracheal inflammatory myofibroblastic tumor in a male child was reported. The clinical characteristics, diagnosis, treatment and prognosis of the disease were reviewed based on the literature, and a differential diagnosis between inflammatory myofibroblastic tumor and hamartoma was performed to ultimately confirm the nature of the tumor in the child.

This patient suffered from severe subglottic stenosis(grade Ⅳb). During partial cricotracheal resection, we cut through the cricothyroid membrane and the cricoid arch along the line from the lower edge of the thyroid cartilage to 5 mm of the inferior thyroid cartilage corner anteromedially. This can protect the cricothyroid joint, effectively protect the recurrent laryngeal nerve, and also support the airway. Strictly adhere to airway separation, avoid excessive separation of scars, and combine with reasonable postoperative management to achieve a safe extubation.

Blunt traumatic tracheobronchial injury is rare, but can be potentially life-threatening. It accounts for only 0.5%-2% of all trauma cases. Patients may present with non-specific signs and symptoms, requiring a high index of suspicion with accurate diagnosis and prompt treatment. A 26-year-old female was brought into the emergency department after sustained a blunt trauma to the chest from a high impact motor vehicle accident. She presented with signs of respiratory distress and extensive subcutaneous emphysema from the chest up to the neck. Her airway was secured and chest drain was inserted for right sided pneumothorax. CT of the neck and thorax revealed a collapsed right middle lung lobe with a massive pneumothorax, raising the suspicion of a right middle lobe bronchus injury. Diagnosis was confirmed by bronchoscopy. In view of the difficulty in maintaining her ventilation and persistent pneumothorax with a massive air leak, immediate right thoracotomy via posterolateral approach was performed. The right middle lobar bronchus tear was repaired. There were no intra- or post-operative complications. She made an uneventful recovery. She was asymptomatic at her first month follow-up. A repeated chest X-ray showed expanded lungs. Details of the case including clinical presentation, imaging and management were discussed with an emphasis on the early uses of bronchoscopy in case of suspected blunt traumatic tracheobronchial injury. A review of the current literature of tracheobronchial injury management was presented.

Objective: To examine the outcomes of Slide tracheoplasty for the children with severe congenital tracheal stenosis received previous repeated balloon dilatation or metal stent placement under endoscopy. Methods: A retrospective study was conducted in 9 children with congenital tracheal stenosis undergoing previous interventional therapy under tracheoscopy and later received Slide tracheoplasty due to obvious respiratory symptoms at Department of Cardiac Surgery, Qilu Children's Hospital of Shandong University between February 2017 and July 2021. There were 7 males and 2 females with a median age at operation of 72.4 months (range: 13.3 to 98.9 months), and the median weight was 19.0 kg (range: 9.0 to 33.0 kg). Among the 9 patients, 2 patients began to receive repeated balloon dilatation (more than 3 times) 17.8 and 51.8 months ago respectively. One patient received metal stents placement into the trachea for 4 days and the other 6 children for median 56.8 months (range: 21.6 to 74.2 months). Complete tracheal cartilage rings and long segmental stenosis were present. in all 9 children. Operative details and outcome measures, including the need for endoscopic airway intervention and mortality, were collected. Results: Slide tracheoplasty was performed in all cases. Two patients with repeated balloon dilatation had different thickness of tracheal wall, local scar hyperplasia and irregular lumen. Among them, 1 case had obvious local calcification of tracheal wall, which was difficult to suture. The metal stent in one patient with short time of placement was completely removed. However, only part of the metal stents could be removed due to the long placement time in the other 6 cases. There was no operative death in the 9 children. The median postoperative tracheal intubation time was 25.3 hours (range: 17.4 to 74.5 hours). A silicone stent was placed in the trachea of 1 child due to obvious respiratory symptoms. Follow-up of median 11 months (range: 1 to 23 months) showed that no death occurred after discharge and all children had basically normal activity tolerance with no obvious respiratory symptoms. Conclusions: Slide tracheoplasty is feasible for children undergoing prior balloon dilatation or metal stents placement. Previously repeated balloon dilatation or metal stent placement under endoscopy increased the difficulty of slide tracheoplasty, the metal stent could not be completely removed after a long time.

Tissue engineering, as a new technology, provides a new avenue for the reconstruction of circumferential tracheal defects, which has always been a tremendous challenge for surgeons around the world. Recently, technologies such as decellularization, 3-dimensional printing, electrospinning and cell sheet have significantly enhanced the chondrification. Implantation of epithelial cells or transplantation of epithelial cell sheets also has accelerated the process of epithelialization. And pedicle muscle flap proved to be a reliable strategy for vascularization of tissue-engineered trachea. But it is still a huge challenge to achieve circumferential tracheal functional reconstruction. The key difficulty lies in how to simultaneously realize the functional regeneration of cartilage, blood vessels and epithelial tissues of tissue-engineered trachea. Therefore, how to integrate the above schemes and finally realize segmental tracheal reconstruction needs further research. This article reviews the research progress of repairing circumferential tracheal defects based on tissue engineering technology.
