ABSTRACT

Malignant Central Airway Obstruction (MCAO) encompasses significant and symptomatic narrowing of the central airways that can occur due to primary lung cancer or metastatic disease. Therapeutic bronchoscopy is associated with high technical success and symptomatic relief and includes a wide range of airway interventions including airway stents. Published literature suggests that stenting practices vary significantly across the world primarily due to lack of guidance. This document aims to address this knowledge gap by addressing relevant questions related to airway stenting in MCAO. An international group of 17 experts from 17 institutions across 11 countries with experience in using airway stenting for MCAO was convened as part of this guideline statement through the World Association for Bronchology and Interventional Pulmonology (WABIP). We performed a literature and internet search for reports addressing six clinically relevant questions. This guideline statement, consisting of recommendations addressing these six PICO questions, was formulated by a systematic and rigorous process involving the evaluation of published evidence, augmented with expert experience when necessary. Panel members participated in the development of the final recommendations using the modified Delphi technique.

ABSTRACT

INTRODUCTION: Foreign body airway obstruction (FBAO) is a life-threatening condition. We aimed to quantify the impact of bystander FBAO interventions on survival and neurological outcomes. METHODS: We conducted a Japan-wide prospective, multi-center, observational study including all FBAO patients who presented to the Emergency Department from April 2020 to March 2023. Information on bystander FBAO interventions was collected through interviews with emergency medical services personnel. Primary outcomes included 1-month survival and favorable neurologic outcome defined as Cerebral Performance Category 1 or 2. We performed a multivariable logistic regression and a Cox proportional hazards modeling to adjust for confounders. RESULTS: We analyzed a total of 407 patients in the registry who had the median age of 82 years old (IQR 73-88). The FBAO incidents were often witnessed (86.5%, n = 352/407) and the witnesses intervened in just over half of the cases (54.5%, n = 192/352). The incidents frequently occurred at home (54.3%, n = 221/407) and nursing home (21.6%, n = 88/407). Common first interventions included suction (24.8%, n = 101/407) and back blow (20.9%, n = 85/407). The overall success rate of bystander interventions was 48.4% (n = 93/192). About half (48.2%, n = 196/407) survived to 1-month and 23.8% patients (n = 97/407) had a favorable neurological outcome. Adjusting for pre-specified confounders, bystander interventions were independently associated with survival (hazard ratio, 0.55; 95% CI, 0.39-0.77) and a favorable neurological outcome (adjusted OR, 2.18; 95% CI, 1.23-3.95). CONCLUSION: Bystander interventions were independently associated with survival and favorable neurological outcome, however, they were performed only in the half of patients.

ABSTRACT

INTRODUCTION: Electrocautery with a snare probe offers a tool for the treatment of endobronchial polyps. The aim of this study was to demonstrate the efficacy of the snare probe in patients undergoing rigid bronchoscopy due to central airway obstruction. METHODS: This retrospective descriptive study included patients who underwent rigid bronchoscopy with an electrocautery snare probe for the diagnosis and/or treatment of endobronchial polyps in an interventional pulmonology unit. RESULTS: The mean age of the 47 patients (38 men) with endobronchial polypoid lesions was 61.5 years. Six lesions (12.8%) were located in the trachea, 6 (12.8%) in the right main bronchus, 11 (23.4%) in the left main bronchus, and 24 (51.1%) in the lobar bronchi. Twenty-eight lesions (59.5%) were malignant. Prior to the procedure, 6 (12.8%) patients had grade 1 obstruction, 6 (12.8%) had grade 2 obstruction, 15 (31.9%) had grade 3 obstruction, and 20 (42.6%) had grade 4 obstruction. In terms of airway obstruction after the procedure, grade 1 was present in 46 (97.9%) patients and grade 2 was present in 1 (2.1%) patient. No major complication developed in 93.6% of the patients. During a mean follow-up period of 48 months, 85.1% of the patients did not experience recurrence. CONCLUSION: Our results demonstrate that the snare probe can be used to effectively and reliably establish airway patency in patients with central airway obstruction due to endobronchial polypoid lesions.

ABSTRACT

PURPOSE: To summarize and analyze the safety and efficacy of a Y-shape Sigma stent loaded with I125 in patients with inoperable malignant main airway obstruction. METHODS: This study was approved by the Institutional Ethics Committee, and a written informed consent was obtained from each participant. A Y-shape Sigma stent loaded with I125 was placed under vision from rigid bronchoscopy. The primary endpoint was alleviation of symptoms and improvement of Karnofsky Performance Status (KPS) score, and the secondary endpoint was complications and technical success. RESULTS: From November 2018 through June 2023, total 33 patients with malignant airway obstruction were palliatively treated by installing Y-shape Sigma stents loaded with I125. The airway lumen was immediately restored and the average airway opening significantly increased to 70 ± 9.4% after the procedure from baseline 30.2 ± 10.5% (p < 0.05). Average KPS score was improved from baseline 30.0 ± 10.0 to 70.0 ± 10.0 (p < 0.05) as well as PaO2 from baseline 50.1 ± 15.4 mmHg to 89.3 ± 8.6 mmHg (p < 0.05). The technical success rate of placing the stent in this study was 73%, and adverse events or complications including bleeding, I125 loss, and airway infection occurred during or after the procedure. CONCLUSION: Placement of Y-shape Sigma stents under vision from rigid bronchoscopy in the patients with malignant airway obstruction is feasible and it immediately alleviates dyspnea and significantly improves quality of life.

ABSTRACT

BACKGROUND AND OBJECTIVE: EpiGETIF is a web-based, multicentre clinical database created in 2019 aiming for prospective collection of data regarding therapeutic rigid bronchoscopy (TB) for malignant central airway obstruction (MCAO). METHODS: Patients were enrolled into the registry from January 2019 to November 2022. Data were prospectively entered through a web-interface, using standardized definitions for each item. The objective of this first extraction of data was to describe the population and the techniques used among the included centres to target, facilitate and encourage further studies in TB. RESULTS: Overall, 2118 patients from 36 centres were included. Patients were on average 63.7 years old, mostly male and smokers. Most patients had a WHO score ≤2 (70.2%) and 39.6% required preoperative oxygen support, including mechanical ventilation in 6.7%. 62.4% had an already known histologic diagnosis but only 46.3% had received any oncologic treatment. Most tumours were bronchogenic (60.6%), causing mainly intrinsic or mixed obstruction (43.3% and 41.5%, respectively). Mechanical debulking was the most frequent technique (67.3%), while laser (9.8%) and cryo-recanalization (2.7%) use depended on local expertise. Stenting was required in 54.7%, silicone being the main type of stent used (55.3%). 96.3% of procedure results were considered at least partially successful, resulting in a mean 4.1 points decrease on the Borg scale of dyspnoea. Complications were noted in 10.9%. CONCLUSION: This study exposes a high volume of TB that could represent a good source of future studies given the dismal amount of data about the effects of TB in certain populations and situations.

ABSTRACT

BACKGROUND: Foreign body airway obstruction (FBAO) stands as an important contributor to accidental fatalities, yet prompt bystander interventions have been shown to improve survival. This study aimed to evaluate the incidence, interventions, and survival outcomes of patients with out-of-hospital cardiac arrest (OHCA) related to FBAO in comparison to patients with non-FBAO OHCA. METHODS: In this population-based cohort study, we included all OHCAs in Denmark from 2016 to 2022. Cases related to FBAO were identified and linked to the patient register. Descriptive and multivariable analyses were performed to evaluate prognostic factors potentially influencing survival. RESULTS: A total of 30,926 OHCA patients were included. The incidence rate of FBAO-related OHCA was 0.78 per 100,000 person-years. Among FBAO cases, 24% presented with return of spontaneous circulation upon arrival of the emergency medical services. The 30-day survival rate was higher in FBAO patients (30%) compared to non-FBAO patients (14%). Bystander interventions were recorded in 26% of FBAO cases. However, no statistically significant association between bystander interventions or EMS personnels' use of Magill forceps and survival was shown, aOR 1.47 (95 % CI 0.6-3.6) and aOR 0.88 (95% CI 0.3-2.1). CONCLUSION: FBAO-related OHCA was rare but has a higher initial survival rate than non-FBAO related OHCA, with a considerable proportion of patients achieving return of spontaneous circulation upon arrival of the emergency medical service personnel. No definitive associations were established between survival and specific interventions performed by bystanders or EMS personnel. These findings highlight the need for further research in this area.

ABSTRACT

Subgaleal hematoma, characterised by blood accumulation between the galea aponeurosis and the periosteum, is rarely reported in adults. A man with liver cirrhosis experienced airway obstruction secondary to an extensive subgaleal hematoma due to superficial temporal artery injuries. Within 6 hours after injury, swelling of the patient's head and neck was noted, which was associating with inspiratory wheezing and paradoxical breathing, thus necessitating emergency intubation. The branches of the superficial temporal artery were identified as the bleeding source via angiography. Subsequently, endovascular embolisation was successfully performed. This case highlights a rare association between airway obstruction and subgaleal hematoma, originating from injuries of the superficial temporal artery in an adult patient with severe coagulopathy. Airway obstruction was secondary to the hematoma progression into the facial and neck regions. It is crucial to identify and address alternative bleeding sources if conservative treatments or initial interventions for subgaleal hematomas are proven ineffective.

ABSTRACT

BACKGROUND: In elderly patients with malignant central airway obstruction (MCAO), the treating physicians often hesitate to undertake transbronchial interventions (TBIs) as a palliative procedure in view of the advanced age of the patients. METHODS: We conducted this retrospective study to evaluate the differences in the feasibility, tolerability, and effectiveness of TBIs between elderly (aged 75 years old or above; elderly group; n=27) and nonelderly (aged below 75 years old; nonelderly group; n=50) patients with MCAO. The primary endpoint was the incidence of complications during (within 24 hours) and after (>24 hours) TBIs. RESULTS: The mean age of the patients was 81 years in the elderly group and 61 years in the nonelderly group. The complications encountered during/after TBI included endobronchial bleeding or hypoxemia requiring intubation occurring during the TBIs, and bacterial pneumonia, airway reocclusion, and stent migration occurring after the TBIs, although there was no difference in the frequency of complications during/after the TBIs between the elderly group and nonelderly group (26% vs. 30%, P =0.706). There was no difference in the percentage of patients in whom successful airway recanalization was achieved by TBI (93% vs. 80%, P =0.197), the percentage of patients who showed symptomatic improvement after the TBIs (67% vs. 76%, P =0.380) and the OS after the TBIs (6.1 vs. 7.3 months, P =0.704) between the 2 groups. CONCLUSION: TBIs can be undertaken without hesitation as a palliative procedure in elderly patients with MCAO.

ABSTRACT

BACKGROUND: Nasal mask (NM) and oronasal masks (OM) can be used to provide noninvasive ventilation (NIV). Recent studies suggested that OM is the most used interface and that there is no difference in efficacy or in tolerance between OM and NM for chronic use. However, studies focusing on video laryngoscopy underlined the impact of OM in residual upper airway obstruction (UAO) under NIV. We sought to assess the real-life practice of switching from OM to NM when UAO events persist despite high EPAP levels. METHODS: In an open-label single center prospective cohort study, data from files and full night polysomnography on NM and OM were collected for patients wearing OM and presenting an UAO index ≥15/h despite an EPAP level ≥ 10 cmH20. RESULTS: Forty-four patients were included in the study. In 31 patients (74 %), switching to a NM reduced UAOi to ≥10/h. Interestingly, 92 % of these patients still had NM at 3 to 12 months of follow-up. Switching to a NM was also associated with a trend in paCO2 reduction and significant improvements in Epworth, sleep quality and NIV compliance. Successful interface switching was significantly associated with female gender, and a trend was observed in non-smokers. CONCLUSION: As for CPAP, switching to a NM improved NIV efficacy in a selected group of patients presenting residual UAO events despite high EPAP levels. Additionally, this switch has an impact on compliance and subjective sleepiness. Thus, in patients with persisting UAO on OM, switching to a NM could be a first-line intervention before considering further investigation such as polygraphy or video laryngoscopy. We also derive an algorithm for mask allocation and adaptation in acute and chronic NIV use.

ABSTRACT

BACKGROUND: Pediatric tracheostomy decannulation protocols vary among institutions and may include toleration of Passy Muir Valve (PMV), microlaryngoscopy and bronchoscopy (MLB) findings, and polysomnography evaluation. Transtracheal pressure (TTP) is an objective measurement utilized to evaluate PMV toleration. We aimed to investigate the role of TTP in decannulation candidates and compare TTP measurements with polysomnography and MLB findings. METHODS: A retrospective cohort study of children who underwent TTP measurement during PMV trial between December 2012 and November 2022. RESULTS: A total of 79 patients underwent TTP measurement and MLB evaluation; of these, 16 (20.3%) patients had a capped polysomnography. Twenty-eight (35.4%) patients had TTPs ≤10 cm H2O, and 51 (64.6%) patients had TTPs >10 cm H2O. The most common indication for tracheostomy was upper airway obstruction (n = 41, 51.9%), followed by a need for mechanical ventilation (n = 24, 30.4%). Twenty-five (31.6%) patients were decannulated. Patients with TTPs ≤10 cm H2O had a mean Apnea-Hypopnea Index of 0.17 ± 0.26/h compared with 6.93 ± 7.67/h in those with TTPs >10 cm H2O, p = 0.0365. Patients with TTPs >10 cm H2O were found to have a significantly higher occurrence of airway obstruction (96.1% vs. 46.4%, p < 0.0001) and multilevel airway obstruction (70.6% vs. 21.4%, p < 0.0001) on MLB. Neither TTP measured at time of PMV assessment nor capped polysomnography was associated with successful decannulation. CONCLUSIONS: TTP measurements at time of PMV evaluation are associated with polysomnography and MLB findings. One-time PMV measurements were not indicative of decannulation success.

ABSTRACT

PURPOSE: Diagnosing pediatric induced laryngeal obstruction (ILO) requires equipment typically available in specialist settings, and patients often see multiple providers before a diagnosis is determined. This study examined the financial burden associated with the diagnosis and treatment of ILO in pediatric patients with reference to socioeconomic disadvantage. METHODS: Adolescents and children (<18 years of age) diagnosed with ILO were identified through the University of Madison Voice and Swallow Outcomes Database. Procedures, office visits, and prescribed medications were collected from the electronic medical record. Expenditures were calculated for two time periods (1) pre-diagnosis (first dyspnea-related visit to diagnosis), and (2) the first year following diagnosis. The Area Deprivation Index (ADI) was used to estimate patient socioeconomic status to determine if costs differed with neighborhood-level disadvantage. RESULTS: A total of 113 patients met inclusion criteria (13.9 years, 79% female). Total pre-diagnosis costs of ILO averaged $6486.93 (SD = $6604.14, median = $3845.66) and post-diagnosis costs averaged $2067.69 (SD = $2322.78; median = $1384.12). Patients underwent a mean of 3.01 (SD = 1.9; median = 2) procedures and 5.8 (SD = 4.7; median = 5) office visits prior to diagnosis. Pharmaceutical, procedure/office visit, and indirect costs significantly decreased following diagnosis. Patients living in neighborhoods with greater socioeconomic disadvantage underwent fewer procedures and were prescribed more medication than those from more affluent areas. However, total expenditures did not differ based on ADI. CONCLUSIONS: Pediatric ILO is associated with considerable financial costs. The source of these costs, however, differed according to socioeconomic advantage. Future work should determine how ILO diagnosis and management can be more efficient and equitable across all patients. Laryngoscope, 134:3384-3390, 2024.

ABSTRACT

The aim of this review is to summarise evidence that became available after publication of the 2017 European Respiratory Society statement on the diagnosis and management of obstructive sleep apnoea syndrome (OSAS) in 1- to 23-month-old children. The definition of OSAS in the first 2 years of life should probably differ from that applied in children older than 2 years. An obstructive apnoea-hypopnoea index >5 events·h-1 may be normal in neonates, as obstructive and central sleep apnoeas decline in frequency during infancy in otherwise healthy children and those with symptoms of upper airway obstruction. A combination of dynamic and fixed upper airway obstruction is commonly observed in this age group, and drug-induced sleep endoscopy may be useful in selecting the most appropriate surgical intervention. Adenotonsillectomy can improve nocturnal breathing in infants and young toddlers with OSAS, and isolated adenoidectomy can be efficacious particularly in children under 12 months of age. Laryngomalacia is a common cause of OSAS in young children and supraglottoplasty can provide improvement in children with moderate-to-severe upper airway obstruction. Children who are not candidates for surgery or have persistent OSAS post-operatively can be treated with positive airway pressure (PAP). High-flow nasal cannula may be offered to young children with persistent OSAS following surgery, as a bridge until definitive therapy or if they are PAP intolerant. In conclusion, management of OSAS in the first 2 years of life is unique and requires consideration of comorbidities and clinical presentation along with PSG results for treatment decisions, and a multidisciplinary approach to treatment with medical and otolaryngology teams.

ABSTRACT

Lung cancer can cause fatal central airway obstruction. Rapid airway clearance is necessary in some cases, but ventilator management may be insufficient to maintain oxygenation levels. Venovenous extracorporeal membrane oxygenation (VV-ECMO) may be an effective rescue therapy for respiratory failure, but its efficacy in treating tumor-related airway obstruction is unknown. We herein report a case of central airway obstruction and severe acute respiratory failure due to small-cell lung cancer successfully treated with VV-ECMO, bronchoscopic airway intervention, and chemotherapy. VV-ECMO can be an effective option for the treatment of central airway obstruction with acute respiratory failure due to lung cancer.

ABSTRACT

OBJECTIVE: Drug-induced sleep endoscopy (DISE) is an established diagnostic procedure to assess the upper airway in patients with obstructive sleep apnea. During DISE airway opening is regularly simulated by various maneuvers. One of them is mandibular advancement by the modified jaw-thrust maneuver (MJTM). MATERIAL AND METHODS: All DISE examinations evaluated by VOTE classification in the last 15 months were included. The effect of MJTM on anatomical levels was analyzed retrospectively. Frequency and type of collapse at the anatomic levels were recorded. Apnea-hypopnea index (AHI), body mass index (BMI), Epworth Sleepiness Scale (ESS) were determined. RESULTS: 61 patients were included (f=13, m=48, 54.3±12.9 y, ESS 11±5.5, AHI 30.2±19/h, BMI 29.7±4.5 kg/m2). A correlation of r=0.30 was found between AHI and BMI (p=0.02). At velum level, concentric collapse was detected in 16.4%, anterior-posterior (a.p.) collapse in 70.5%, and lateral collapse in 11.5%. A resolution of the collapse using the MJTM was observed in 75.5% of patients. However, in the presence of concentric collapse, opening was evident in 33.3% of cases in contrast to 86.5% in patients with a.p. collapse. Base of tongue collapse was resolved in 98.0% of the cases. CONCLUSION: A correlation between the success of the MJTM on airway opening at the velum level and the pattern of palatal collapse was found. In therapies aimed at mandibular advancement, e.g. hypoglossal nerve stimulation, an effect on velopalatal airway opening has relevance, so optimization of preoperative diagnosis is of particular importance.

ABSTRACT

INTRODUCTION: Micrognathic neonates are at risk for upper airway obstruction, and many require intubation in the delivery room. Ex-utero intrapartum treatment is one technique for managing airway obstruction but poses substantial maternal risks. Procedure requiring a second team in the operating room is an alternative approach to secure the obstructed airway while minimizing maternal risk. The aim of this study was to describe the patient characteristics, airway management, and outcomes for micrognathic neonates and their mothers undergoing a procedure requiring a second team in the operating room at a single quaternary care children's hospital. METHODS: This was a retrospective descriptive study. Subjects had prenatally diagnosed micrognathia and underwent procedure requiring a second team in the operating room between 2009 and 2021. Collected data included infant characteristics, delivery room airway management, critical events, and medications. Follow-up data included genetic testing and subsequent procedures within 90 days. Maternal data included type of anesthetic, blood loss, and incidence of transfusion. RESULTS: Fourteen deliveries were performed via procedure requiring a second team in the operating room during the study period. 85.7% were male, and 50% had a genetic syndrome. Spontaneous respiratory efforts were observed in 93%. Twelve patients (85.7%) required an endotracheal tube or tracheostomy. Management approaches varied. Medications were primarily a combination of atropine, ketamine, and dexmedetomidine. Oxygen desaturation was common, and three patients experienced bradycardia. There were no periprocedural deaths. Follow-up at 90 days revealed that 78% of patients underwent at least one additional procedure, and one patient died due to an unrelated cause. All mothers underwent cesarean deliveries under neuraxial anesthesia. Median blood loss was 700 mL [IQR 700 mL, 800 mL]. Only one mother required a blood transfusion for pre-procedural placental abruption. DISCUSSION: Procedure requiring a second team in the operating room is a safe and effective approach to manage airway obstruction in micrognathic neonates while minimizing maternal morbidity. CONCLUSIONS: Though shown to be safe and effective, more data are needed to support the use of procedure requiring a second team in the operating room as an alternative to ex-utero intrapartum treatment for micrognathia outside of highly specialized maternal-fetal centers.

ABSTRACT

Foreign body aspiration (FBA) is a common cause of pediatric morbidity, but a standardized protocol to guide decision-making about bronchoscopy is lacking. We aimed to validate a new Foreign body aspiration score (FOBAS) for the pediatric emergency department (ED). Patients aged 0-18 years referred to the ED for suspected FBA were prospectively enrolled. FOBAS was calculated according to clinical features of a choking episode, sudden cough, exposure to nuts, absence of fever and rhinitis, stridor, and unilateral auscultatory and radiological findings. FBA risk was evaluated based on the total score (low, 1-3; moderate, 4-6; high, 7-10). Low-risk children were discharged from the ED and followed clinically. Moderate-risk children were hospitalized and evaluated by a pediatric pulmonologist, and high-risk children were referred directly for therapeutic bronchoscopy. Among the 100 enrolled children (59% males; median age 20 [interquartile range 11-39] months), a foreign body was diagnosed in 1/49 (2%), 14/41 (34.1%), and 9/10 (90%) with low, moderate, and high FOBAS, respectively (P < .001). Logistic regression indicated a higher risk for FBA with higher scores. The odds ratio for each additional point was 2.75 (95% confidence interval 1.78-4.24), and FOBAS showed a high predictive value for FBA (area under the curve 0.89). FOBAS implementation significantly reduced the rate of negative bronchoscopies, from 67.4% annually during 2016-2019 to 50% in 2020 (P = .042). CONCLUSION: FOBAS reliably predicts FBA in cases of suspected FBA and improves management and in-hospital decision-making. WHAT IS KNOWN: • Foreign body aspiration is a major cause of pediatric morbidity and mortality. • Currently, there is no unified protocol for children referred to the emergency department for suspected FBA, therefore, a well-defined algorithm is needed to improve the decision-making process. WHAT IS NEW: • The pediatric Foreign body aspiration score (FOBAS) is a new, prospectively validated clinical score that shows high sensitivity and specificity for the presence of FBA in children. • FOBAS reduces unnecessary admissions and invasive procedures and leads to better clinical outcomes.

ABSTRACT

INTRODUCTION: Fetal goiter is a rare congenital disorder that can present with life-threatening neonatal airway obstruction. Lifesaving and function-preserving airway management strategies are available, but routine delivery affords a limited window for intervention. Accordingly, fetal goiter is reported among the most common indications for ex-utero intrapartum treatment (EXIT). While EXIT prolongs the window for airway intervention to benefit the neonate, it elevates the risk to the pregnant person and requires extensive resources; therefore, data to guide ideal treatment selection are essential. This study aims to compare perinatal airway interventions between individuals with a birth hospitalization discharge diagnosis (BHDD) of goiter and the general population. MATERIALS AND METHODS: Individuals with and without BHDD of goiter were identified in the Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Database from 2000 to 2019. The frequency of airway interventions on day of life (DOL) 0 or 1 were compared using the Rao-Scott chi-square test. Additionally, gestational age, type of intervention, complications, mortality, birth weight, and length of stay were examined for the goiter cohort. RESULTS: Two-hundred eighty-seven weighted cases of goiter were identified in the study period. The population was 61 % male, 55 % White, and median birthweight was 3.3 kg. The median length of stay was 4.3 days, and average total charges were $42,332. Airway intervention on DOL 0 or 1 was performed in 16.9 % of individuals with goiter compared to 1.6 % in neonates without goiter (p < 0.001). Interventions in the goiter cohort included endotracheal intubation in 16 % of cases, laryngoscopy/bronchoscopy in 1-5% of cases, and tracheostomy in <1 % of cases. Fewer than 1 % of individuals undergoing intubation additionally had mass decompression/resection on DOL 0 or 1. No neonates received extracorporeal membrane oxygenation cannulation or cardiopulmonary resuscitation. Hypoxic encephalopathy occurred in <1 % of cases, among which endotracheal intubation was the only airway intervention performed. There were no mortalities among neonates with goiter. CONCLUSION: Individuals with BHDD of goiter receive significantly higher rates of perinatal airway intervention. In most cases, endoscopic interventions alone were sufficient to avoid hypoxic neurological complications. These findings contribute to data to aid in clinical counseling and empower patients to make informed decisions according to their values and treatment goals.
