RESUMEN
Introducción: La infección por SARS-CoV-2 puede presentar síndrome de distrés res-piratorio agudo con requerimiento de ventilación mecánica prolongada y retraso en la realización de traqueostomía. Esto trae como consecuencia un incremento en casos de estenosis traqueal y la necesidad de métodos menos invasivos para su abordaje. Métodos: Estudio descriptivo de corte transversal, desde marzo 2020 hasta diciem-bre 2021 en el Hospital Universitario Nacional de Colombia, en adultos con estenosis traqueal postintubación asociado SARS-CoV-2. Se realizó análisis univariado entre los grupos con infección o no por SARS-CoV-2 como control, y reintervención, grado de estenosis, uso de inyección intramucosa con dexametasona intratraqueal o múltiples estenosis como desenlaces de importancia. Se usó test exacto de Fisher, t Student y Man-Whitney según la naturaleza de variables. Se consideró p estadísticamente significativo menor a 0.05.Resultados: Se identificaron 26 pacientes, 20 tenían COVID-19 y 6 no. Se encontraron diferencias en edad (p=0,002), epilepsia (p=0,007) y estenosis múltiple (p= 0,04). En 85% de los casos se utilizó láser blue más dilatación con balón pulmonar, en 35% inyección intramucosa con dexametasona intratraqueal y reintervención en 35%, sin diferencias significativas entre grupos. Conclusiones: Se observó un incremento tres veces mayor de pacientes con estenosis múltiple en el grupo de infección por COVID-19, así mismo se encontró que el método más utilizado en este grupo para la recanalización fue el uso de láser blue más dilatación con balón pulmonar y la innovación en el uso de inyección intramucosa.
Introduction: SARS-CoV-2 infection can lead to acute respiratory distress syndrome with a prolonged need for mechanical ventilation and delayed tracheostomy, resulting in an increase in cases of tracheal stenosis and the necessity for less invasive approaches.Methods: A descriptive cross-sectional study was conducted from March 2020 to December 2021 at the Hospital Universitario Nacional de Colombia, focusing on adults with post-intubation tracheal stenosis associated with SARS-CoV-2. Univariate analysis was performed between groups with or without SARS-CoV-2 infection as a control, considering reintervention, degree of stenosis, use of intratracheal steroids, or multiple stenoses as important outcomes. Fisher's exact test, Student's t-test, and Mann-Whit-ney test were employed based on the nature of variables. A p-value less than 0.05 was considered statistically significant.Results: A total of 26 patients were included, with 20 having COVID-19 and 6 without. Significant differences were found in age (p=0.002), epilepsy (p=0.007), and multiple stenosis (p=0.04). In 85% of cases, laser blue plus balloon pulmonary dilation was used, intratracheal dexamethasone in 35%, and reintervention in 35%, with no significant differences between groups.Conclusions: A threefold increase in subglottic stenosis was observed during the SARS-CoV-2 pandemic, with more instances of multiple stenosis and predominantly the use of laser blue plus balloon pulmonary dilation as a successful recanalization technique. There was a higher use of intratracheal dexamethasone in this group compared to oth-er pathologies causing tracheal stenosis.

BACKGROUND: Patients with long-segment airway stenosis not amenable to conventional surgery may benefit from tracheal transplantation. However, this procedure has been only anecdotally reported, and its indications, techniques, and outcomes have not been extensively reviewed. METHODS: We conducted a systematic Literature search to identify all original articles reporting attempts at tracheal transplantation in humans. RESULTS: Of 699 articles found by the initial search, 11 were included in the systematic review, describing 14 cases of tracheal transplantation. Patients underwent transplantation for benign stenosis in nine cases, and for malignancies in five cases. In 12 cases blood supply to the trachea was provided by wrapping the graft in a vascularized recipient's tissue, while in 2 cases the trachea was directly transplanted as a vascularized composite allograft. The transplantation procedure was aborted before orthotopic transplantation in two patients. Among the remaining 12 patients, there was 1 operative mortality, while 4 patients experienced complications. Immunosuppressants drugs were administered to the majority of patients postoperatively, and only one group of authors attempted their withdrawal, in five patients. At the end of follow-up, all 11 patients surviving the operation were alive, but 2 had a recurrent tracheal stenosis requiring an airway appliance for breathing. CONCLUSION: Human tracheal transplantation is still at an embryonic phase. Studies available in the Literature report different surgical techniques, and information on long-term outcomes is still limited. Future research is needed in order to understand the clinical value of this procedure.

Thyroid involvement is rare in pediatric Langerhans cell histiocytosis (LCH). It may cause airway narrowing, leading to acute-onset respiratory distress. Severe cases may require emergent surgical interventions such as thyroidectomy, which should be avoided in children due to higher rates of complication, particularly in infancy. There is currently no consensus on the indications for surgical treatment in LCH with thyroid involvement. In this report, we describe the cases of two children who presented with tracheal stenosis caused by thyroid LCH, both of which were successfully treated by early induction of chemotherapy, and one of which was also treated for a shorter duration. Mutation analysis detected in-frame deletions of BRAF exon 12 in both cases. These cases suggest that timely diagnosis and administration of chemotherapy may alleviate severe airway obstruction and reduce the need for thyroidectomy in pediatric patients with thyroid LCH.

INTRODUCTION: Comorbidities such as chronic lung disease and gastroesophageal reflux (GERD), prematurity, and numerous other conditions may impact the success of LTR. Single-center studies are limited in terms of patient numbers and may be underpowered. OBJECTIVES: To analyze the impact of specific comorbidities on the operation-specific and overall surgical success of LTR in a large multicenter cohort and validate a predictive model for surgical success. METHODS: A large retrospective multicenter 10-year review was undertaken to validate the data of a previous single-center study (Wertz et al. Laryngoscope 2020) which identified specific predictive comorbidities which impacted LTR outcomes. A Monte Carlo simulation based on the previous data set suggested that 300-400 cases would be needed to optimize the statistical power of a Bayesian model developed from the single-center data to predict surgical success. An IRB-approved data-sharing agreement was executed for 4 large U.S. CENTERS: A virtual REDCap® data entry form inquired about patient characteristics that best predicted surgical success in the single-center model. These included demographics, surgical approaches, cardiac, airway, genetic, endocrine, musculoskeletal, gastrointestinal, and pulmonary comorbidities; details of the surgical procedures, and results of esophagogastroduodenoscopy (EGD), esophageal pH/impedance and flexible bronchoscopy with bronchioalveolar lavage (BAL) were included. Surgical success defined as successful decannulation or resolution of airway symptoms was recorded as single surgery success and overall success following open surgical revision surgery. Multivariate Bayesian analysis, logistical regression, and Kaplan-Meier analysis were performed. RESULTS: 542 patients were identified, including 165 from the single-center study and an additional 377 patients from the multicenter group. The median age was 36 months at the time of the most recent surgery. 70.9% of the LTRs were double-staged procedures. The overall success rate was 86.4% and operation-specific success rate was 69.2%. The specific comorbidities and aerodigestive test results that impacted success based on univariate analysis included staging, bronchiectasis, pulmonary hypertension, GERD, ASD, PDA, grade of stenosis, advanced levels of stenosis, Trisomy 21, MRSA, prior open surgery at another hospital, and gross appearance on EGD. Bayesian model averaging with backward selection was used to validate and refine a predictive model for surgical success with favorable receiver operating curve characteristics - AUC values of 0.827 for single surgery success and 0.797 for overall success. DISCUSSION: With over 500 patients reviewed, this was the largest multicenter study of LTR to date, which elucidated the impact of comorbidities on success with LTR and was able to improve upon the predictive modeling based on single-center data. Patient factors are most critical in the outcome of LTR. Stage and levels of stenosis, as well as pulmonary and GI conditions most strongly impact the likelihood of success. Future prospective case-control studies will be performed to further optimize the current model for outcome prediction and patient management.

RATIONALE: Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) is used in tracheostomy but not in cases of airway obstruction. This case report explores the use of THRIVE for managing airway obstruction during tracheostomy in patients with subglottic and tracheal stenosis, thereby addressing the current knowledge gap and exploring its potential for airway management. PATIENT CONCERNS: A 63-year-old female with subglottic and tracheal stenoses underwent tracheostomy. Multiple attempts to establish a patent airway were unsuccessful, and oxygen saturation dropped to 56%. DIAGNOSIS: Endotracheal tube was directed toward the tracheal wall, causing airway obstruction. INTERVENTIONS: THRIVE was administered to the patient. Subsequently, the tube position was adjusted to enhance ventilation. OUTCOMES: The patient's oxygen saturation increased to 99%. The postoperative complications, including subcutaneous emphysema, pneumothorax, pneumomediastinum and pneumopericardium, resolved. The patient was discharged on postoperative day 9. LESSONS: THRIVE could be considered a temporary measure to enhance oxygenation before initiating a definitive treatment strategy.

Laryngotracheal stenosis, congenital or acquired, is a common cause of pediatric airway obstruction. Acquired subglottic stenosis frequently results from prolonged neonatal intubation. The clinical presentation of subglottic stenosis is variable, ranging from biphasic stridor and frequent upper respiratory infections to acute airway compromise. Optimal patient care requires clinical coordination within a multidisciplinary subspecialty team. Medical management includes optimizing respiratory status, gastroesophageal reflux, speech, feeding, nutrition therapies, and providing psychosocial support. If surgical intervention is required, the otolaryngologist, anesthesiologist, and perioperative team must collaborate closely to ensure successful operative outcomes. This narrative review of laryngotracheal stenosis will discuss the pathophysiology, clinical evaluation, medical management, and surgical interventions, and focus on the perioperative anesthetic considerations for children undergoing laryngotracheal reconstruction.

OBJECTIVE: Examine differences in cost between single stage (ss) versus double stage (ds) laryngotracheal reconstruction (LTR) for pediatric subglottic stenosis. STUDY DESIGN: Retrospective chart review of children who underwent ssLTR or dsLTR from 2014 to 2018 at a single institution. METHODS: Costs related to LTR and post-operative care up to one year after tracheostomy decannulation were extrapolated from charges billed to the patient. Charges were obtained from the hospital finance department and the local medical supplies company. Patient demographics including baseline severity of subglottic stenosis and co-morbidities were noted. Variables assessed include duration of hospital admission, number of ancillary procedures, duration of sedation wean, cost of tracheostomy maintenance, and time to tracheostomy decannulation. RESULTS: Fifteen children underwent LTR for subglottic stenosis. D Ten patients underwent ssLTR, while five underwent dsLTR. Grade 3 subglottic stenosis was more prevalent in patients who underwent dsLTR (100%) than ssLTR (50%). The average per-patient hospital charges for ssLTR was $314,383 versus $183,638 for dsLTR. When estimated mean cost of tracheostomy supplies and nursing care until tracheostomy decannulation was included, the mean total charges associated with dsLTR patients was $269,456. Average hospital stay after initial surgery was 22 days for ssLTR versus 6 days for dsLTR. Average time to tracheostomy decannulation for dsLTR was 297 days. Average number of ancillary procedures needed was 3 versus 8 for ssLTR versus dsLTR. CONCLUSION: For pediatric patients with subglottic stenosis, dsLTR may have a lower cost than ssLTR. Although ssLTR has the benefit of immediate decannulation, it is associated with higher patient charges, as well as longer initial hospitalization and sedation. For both patient groups, fees associated with nursing care comprised the majority of charges. Recognizing the factors that contribute to cost differences between ssLTR and dsLTR may be useful when performing cost-benefit analyses and assessing value in health care delivery.

PURPOSE: Granulation tissue-induced tracheal stenosis (mainly secondary to intubation or lung transplantation) is one of the most common etiologies of benign airway obstructions. Recurrence rates after standard treatment options (surgical resection and/or endobronchial interventions) can inadvertently worsen the stricture through the stimulation of more granulation tissue generation (via increased fibroblast activity and roliferation). Low-dose radiotherapy could be a promising tool to prevent granulation tissue formation after surgery and/or endobronchial interventions regarding its established role in the treatment of keloids or hypertrophic scars, two benign diseases with similar a pathophysiology to tracheal stenosis. This study reviews case reports and small series that used endobronchial brachytherapy (EBBT) or external beam radiotherapy (EBRT) for the management of refractory granulation tissue-induced tracheal stenosis after surgery and/or endobronchial interventions. METHODS AND MATERIALS: Case reports and series (published up to October 2022) that reported outcomes of patients with recurrent granulation tissue-induced tracheal stenosis (after surgery and/or endobronchial interventions) treated by EBBT or EBRT (in definitive or prophylactic settings) were eligible. RESULTS: Sixteen studies (EBBT: nine studies including 69 patients, EBRT: seven studies including 32 patients) were reviewed. The pooled success rate across all studies was 74% and 97% for EBBT and EBRT, respectively. CONCLUSIONS: Radiation therapy appears to be effective in the management of selected patients with recurrent/refractory tracheal stenosis. Response to this treatment is usually good, but further studies with a larger number of patients and long-term followup are necessary to determine the optimal technique, dose, and timing of radiation therapy, late complications, the durability of response, and criteria for patient selection.

OBJECTIVES: Outcome measures of revision open airway surgery in pediatric laryngotracheal stenosis (LTS) are reported. METHODS: Data on 46 pediatric LTS patients undergoing revision open airway surgery were collected retrospectively. The measured outcomes were decannulation rate, time to decannulation, postoperative complications, additional surgery to achieve decannulation, and functional results. RESULTS: The most common revision surgery was partial cricotracheal resection (PCTR) in 21/46, followed by extended PCTR (ePCTR) in 20/46, and laryngotracheal reconstruction (LTR) in 5/46 patients. A 90.7% overall decannulation rate (ODR) and a 74.4% operation-specific decannulation rate (OSDR) were achieved. Delayed decannulation was identified in children aged 5 years or less (p = 0.038) and in patients with previous primary open airway surgery (p = 0.039). Complications were observed in 52.2% of patients. To achieve optimal airway patency, additional open or endoscopic airway surgeries were necessary in 30.4% and 47.7% of patients, respectively. Age 5 years or less (p = 0.034), multiple comorbidities (p = 0.044), revision ePCTR (p = 0.023), and laryngeal stenting (p = 0.018) were risk factors requiring additional open surgery to achieve age-appropriate airway. Failed primary open airway surgery (p = 0.034) and comorbidities (p = 0.044) were risk factors for a higher rate of additional endoscopic surgeries. Postoperatively 63.0% of patients achieved normal breathing, 82.2% were dysphonic and 91.1% were orally fed. CONCLUSIONS: In this report, the patient's age under 5 years, previous primary open airway surgery, medical comorbidities, and laryngeal stenting had a significant negative impact on revision open airway surgery outcomes.

OBJECTIVES: The gold standard treatments for advanced laryngotracheal stenosis (LTS) are represented by partial crico-tracheal (PCTRA) or tracheal resection and anastomosis (TRA). These procedures are potentially burdened by high postoperative complication rates. We investigated the impact of the most common stenosis and patient-related characteristics on the onset of complications in a multicentric cohort. METHODS: We retrospectively analyzed patients who underwent PCTRA or TRA for LTS of different etiologies in three referral centers. We tested the effectiveness of these procedures, the impact of complications on the outcomes, and identified factors causing postoperative complications. RESULTS: A total of 267 patients were included in the study (130 females; mean age, 51.46 ± 17.64 years). The overall decannulation rate was 96.4%. Altogether, 102 (38.2%) patients presented at least one complication, whereas 12 (4.5%) had two or more. The only independent predictor of post-surgical complications was the presence of systemic comorbidities (p = 0.043). Patients experiencing complications needed additional surgery more frequently (70.1% vs. 29.9%, p < 0.001), and had a longer duration of hospitalization (20 ± 10.9 vs. 11.3 ± 4.1 days, p < 0.001). Six of 102 (5.9%) patients with complications had restenosis, although this event did not occur among patients without complications. CONCLUSION: PCTRA and TRA have an excellent success rate even when performed for high-grade LTS. However, a significant percentage of patients may experience complications associated with a longer duration of hospitalization or the need for additional surgeries. The presence of medical comorbidities was independently related to an increased risk of complications. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2910-2919, 2023.

Mastectomy is traditionally performed under general anaesthesia and invasive ventilation, and is often complemented with regional techniques. In this setting, tracheal stenosis can pose a challenge to airway management. The aim of this report is to describe the successful management of a 68-year-old woman with severe subglottic tracheal stenosis undergoing mastectomy due to breast cancer. Surgery was performed without airway instrumentation under an opioid-free regimen consisting of thoracic epidural, propofol and dexmedetomidine perfusion, and non-opioid analgesics. Spontaneous ventilation and adequate perioperative analgesia were achieved. Opioid-free anaesthesia without airway instrumentation, consisting of thoracic epidural anaesthesia and sedation, is a good alternative in patients undergoing mastectomy in whom airway manipulation is best avoided.

BACKGROUND: The optimal treatments for adult benign laryngotracheal stenosis presently remains controversial. The majority of the disadvantages of endoscopic interventions with high recurrence rate and open surgical therapy accompanied by sophisticated techniques, complication and mortality, highlights the dilemma of option for treatments. PURPOSE: To compare endoscopic treatments with open surgical interventions in adult patients with benign laryngotracheal stenosis, analyze their clinical outcomes, recurrence, complication and mortality. METHODS: In the meta-analysis, the databases including PubMed, Embase, Ovid and Web of Science were searched for studies reporting adult benign laryngotracheal stenosis, and clinical outcomes were compared. The duplicate publications, reviews, comments or letters, conference abstracts, case reports were excluded. The random effect model was used for calculating the pooled effect estimates. RESULTS: Eight studies (1627 cases) referring to six retrospective and two prospective researches were ultimately included in the meta-analysis. The decreased risk estimates of recurrence rate in patients receiving open surgical interventions were detected, comparing with endoscopic interventions (P < 0.05). Subgroup analysis revealed that decreased risk estimates of restenosis rate were also observed in patients receiving open surgical interventions compared with endoscopic interventions (P < 0.05), based on prospective studies, Europe and America, < 2-year follow-up, laryngeal stenosis, stenotic length without inter-group difference or stenotic grade II alone. However, there were no statistically significant difference of recurrence rate between the two interventions (P > 0.05) based on retrospective studies, South Asia and Africa, ≥ 2-year follow-up, involving tracheal lesion, stenotic length with inter-group difference, or stenotic grades of I-IV. No notable difference in the incidence of complication or mortality were identified. CONCLUSIONS: Open surgical interventions were more suitable for most laryngotracheal stenosis without contraindications. Endoscopic interventions are increasingly being used to treat simple laryngotracheal stenosis, as well as complex airway stenosis in carefully selected cases. Multi-center prospective randomized controlled trials should be conducted to search for the standard treatments for laryngotracheal stenosis.

BACKGROUND: Endoscopic therapies are firmly established in the management algorithm of benign subglottic and tracheal stenosis (SGTS). The optimal dilation strategy, however, has yet to be elucidated. The objective of this study was to compare the efficacy and safety of balloon versus rigid bronchoplasty in the treatment of benign SGTS. METHODS: De novo cases of benign SGTS at our institution over a 9-year period were retrospectively identified. Patients were divided into 2 groups based on the initial dilation strategy of balloon or rigid bronchoplasty. Demographics, clinical findings, concurrent interventions, lesion characteristics, and complications were analyzed. Two reviewers independently assigned an index and follow-up endoscopic stenosis grade for each case. The mean stenosis grade at follow-up in both groups was then calculated and compared. RESULTS: Sixty-three patients with benign SGTS were included. Most stenoses in the rigid (80%) and balloon (63%) bronchoplasty groups were complex ( P =0.174). In addition, 94% (59/63) of index stenoses were classified as Cotton Myer Grade 3. At follow-up, no significant difference was found in the mean stenosis grade between dilation strategies (1.97 vs. 2.2, P =0.287). Furthermore, no procedural-related complications were observed in either group. CONCLUSION: Balloon and rigid bronchoplasty are safe and effective endoscopic tools in the early management of benign SGTS. A multimodality approach centered around mucosal sparing techniques remains vitally important to the overall and likely long-term success of treating this challenging disease entity.

Tracheal stenosis and tracheomalacia in patients with congenital scoliosis are serious and rare conditions caused by congenital dysplasia, postintubation injury, trauma, and tracheal tumor. Anesthesia of a child with tracheal stenosis is challenging for anesthesiologists. We describe an 8-year-old female patient developed severe tracheal stenosis and tracheomalacia after growing rod implantation for congenital scoliosis. Comprehensive assessment of preoperative pulmonary function and airway morphology, which can be neglected clinically, should be performed in congenital scoliosis patients.

PURPOSE: Pediatric laryngotracheal reconstruction (LTR) for laryngotracheal stenosis (LTS) mandates stenting in certain situations. This study presents a novel commercially available and cost-effective stent, a refashioned foley catheter. METHODS: This prospective clinical study was performed on pediatric cases with LTS up to 8 years. The study was performed in a tertiary referral center. The selection of the proper foley catheter size for age was explained. The atraumatic insertion maneuver of the stent was also shown in detail in different situations of LTS. The endoscopic removal of the stent was also described. The mean follow-up was 6.45 ± 1.3 months. RESULTS: The study included 31 cases using the refashioned foley catheter stents. The study included 17 males and 14 females with a mean age of 3.45 ± 1.09. Subglottic stenosis was the most common cause of LTR in the study (74.2%) cases. The mean duration of stenting was 40.5 ± 3.7 days. Decannulation was achieved in 96.8% of cases. No stent complications were encountered like stent migration, excess granulation tissue, intractable aspiration, or pressure necrosis. CONCLUSION: The refashioned foley catheter is a novel, available, and inexpensive stent that can be utilized for LTR cases for pediatric LTS. The newly described stent is soft, pliable with atraumatic insertion and easy endoscopic removal with minimal complications.

INTRODUCTION: Acquired tracheal stenosis (TS) is a potentially life-threatening condition following prolonged intubation and/or tracheostomy in adult patients with severe Acquired Brain Injury (sABI), requiring a tracheal resection and reconstruction. METHODS: We included 38 sABI adult patients with TS, admitted at a post-acute Neurorehabilitation Hospital. Disability Rating Scale (DRS) and other functional assessment measures were recorded at admission (t1), before TS surgical treatment (t2), and at discharge (t3). Patients were defined as 'improved' when they changed from a more severe to a less severe disability, between time t2 and time t3, and as "not improved" when they did not show any further improvement between t2 and t3, or they already exhibited a disability improvement since time interval t1-t2. RESULTS: Time interval between the injury onset and TS surgical treatment (t2-t0) was associated with the patient's disability improvement, suggesting the t2-t0 time interval ≤ 115 days as a cutoff value for a possible functional recovery. A t2-t0 time interval ≤ 170 days is also associated to absence of persistent dysphagia. CONCLUSIONS: Early TS surgical treatment within 115 days from the injury onset contributes to the improvement of the disability level in patients with sABI, optimizing their functional outcomes and recovery potential.

BACKGROUND: Down Syndrome (DS) patients are more susceptible to either congenital or acquired subglottic stenosis (SGS). This often creates a multilevel airway obstruction and can lead to tracheostomy dependence early in life. As a result, they may require Laryngotracheal Reconstruction (LTR) to achieve decannulation. The primary objective of this study was to assess decannulation rates, time to decannulation and potential barriers to decannulation in DS patients undergoing LTR. METHODS: We performed a retrospective chart review from 2008 to 2021 of 193 children who underwent LTR for treatment for laryngotracheal stenosis at a stand-alone tertiary children's hospital. The relationship between clinical data and decannulation status was evaluated using multivariable logistic regression and Fisher exact tests. Time to decannulation analysis was performed using Kaplan Meier analysis and evaluated with log-rank and Cox proportional hazards regression. RESULTS: We determined that DS patients carry an inherit risk for decannulation failure compared to the general population (OR: 6.112, P = . 044, CI 1.046-35.730). Of the 8 patients with DS only three were decannulated. Overall, patients with Trisomy 21 had a significantly increased time to decannulation when compared to all LTR patients (P = .008, Log-rank). We found that these patients are more likely to have both suprastomal collapse (P = .0004, Fischer's Exact) and Tracheomalacia (P = .034, Fischer's Exact) compared to all other LTR patients. While post-operative tracheomalacia did not significantly affect decannulation failure (P = .056, Fischer's Exact) it did significantly prolong decannulation in all LTR patients (P = .018, Log-rank). CONCLUSION: Trisomy 21 patients are at an increased risk for decannulation failure. Our study illustrates that these poor outcomes are likely a result of conditions more commonly found in this cohort including: narrow tracheal caliber, tracheomalacia and hypotonia.

PURPOSE: Although surgical outcomes have improved in patients with congenital tracheal stenosis (CTS), the management of such patients with complex cardiovascular anomalies (CVAs) remains a challenge. This study aimed to clarify the clinical features of this combination. METHODS: Medical records of 14 patients with complex CVAs who had undergone slide tracheoplasty for CTS between May 2016 and February 2022 were retrospectively reviewed. Complex CVAs were defined as CVAs without left pulmonary artery sling and simple cardiac shunts. Data collected included age and body weight at tracheal reconstruction, preoperative respiratory support, surgery details, and mortality. RESULTS: The median age and body weight at tracheal reconstruction were 3.5 (range, 1-17) months and 4.7 (range, 2.3-8.2) kg, respectively. Simultaneous repair of CTS and CVAs was performed in eight patients and staged repair in six patients. Patients who underwent simultaneous repair required preoperative respiratory support more frequently than those who underwent staged repair (8/8 [100%] vs 2/6 [33.3%]; P = 0.015). No mortality occurred. CONCLUSIONS: Patients with complex CVAs often require tracheal reconstruction in early infancy. Surgical management strategy for this combination was generally decided on the basis of the severity of respiratory symptoms due to CTS.

We reported the free hyoid bone reconstruction of the cricoid cartilage to treat LTS in children. This retrospective case series study included LTS children who underwent hyoid bone separation and T tube implantation. Thirty-four children were included. Twenty-five children were with good outcomes after free hyoid bone reconstruction of the cricoid cartilage. Specifically, the cure rate was 92.8% for the children with mixed stenosis, followed by 63.6% in children with glottis stenosis and 55.6% in children with subglottic stenosis. Free hyoid bone reconstruction of the cricoid cartilage for the management of LTS is feasible, with good outcomes and few complications.
