Mills JF, Monaghan NP, Nguyen SA, Nguyen CL, Clemmens CS, Carroll WW, Pecha PP, White DR. Characteristics and outcomes of interventions for pediatric laryngomalacia: A systematic review with meta-analysis. Int J Pediatr Otorhinolaryngol 2024; 178:111896. [PMID: 38364547 DOI: 10.1016/j.ijporl.2024.111896] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 02/07/2024] [Accepted: 02/11/2024] [Indexed: 02/18/2024]
Abstract
OBJECTIVES To analyze characteristics of children treated for laryngomalacia to determine predictive factors and provide an updated meta-analysis on outcomes. METHODS A systematic review was conducted according to PRISMA guidelines from inception to May 2, 2023, using CINAHL, PubMed, and Scopus databases. Study screening, data extraction, quality rating, and risk of bias assessment were performed by 2 independent reviewers. Data were meta-analyzed using fixed-/random-effects model to derive continuous measures (mean), proportions (%), and mean difference (Δ) with 95% confidence interval (CI). RESULTS 100 articles were identified with information on outcomes of pediatric patients with laryngomalacia (N = 18,317). The mean age was 10.6 months (range: 0 to 252, 95%CI: 9.6 to 11.6, p = 0.00) with a 1.4:1 male to female ratio. Many patients presented with stridor (87.9%, 95% CI: 69.8 to 98.4), and the most common comorbidity at time of diagnosis was gastroesophageal reflux disease (48.8%, 95%CI: 40.9 to 56.8). Based on the patient population included in our analysis, 86.1% received supraglottoplasty (95% CI: 78.7 to 92.1). A total of 73.6% (95% CI: 65.5 to 81.0) had reported complete resolution of symptoms. For patients with a concurrent diagnosis of sleep disordered breathing receiving supraglottoplasty, the apnea-hypopnea index improved with a mean difference of -10.0 (95%CI: 15.6 to -4.5) events per hour post-treatment. CONCLUSIONS Laryngomalacia continues to be a common problem in the pediatric population. Supraglottoplasty remains an effective treatment option leading to symptomatic improvement in many cases. For those with concurrent sleep disordered breathing, supraglottoplasty lowers the apnea-hypopnea index.

Abstract
Laryngomalacia (LM) is the most common airway congenital anomaly and the main cause of stridor in infants. Some patients with severe airway symptoms or with feeding difficulties require surgical intervention. Synchronous airway lesions (SALs) may influence the severity and course of the disease. This study aimed to determine the prevalence of various types of LM and SALs and their influence on surgical intervention decisions and feeding difficulties. Moreover, the study focused on the interrelations between SALs and the type of LM or the presence of feeding difficulties. A retrospective analysis of 106 pediatric patients revealed a significant relationship between type 2 LM and the necessity of surgical treatment. We also found a significant effect of LM type 2 on feeding difficulty. Type 1 LM is significantly more characteristic in premature children. Among different comorbidities, SALs are suspected of modification of the course and severity of LM. This study did not find a significant effect of SALs on the incidence of supraglottoplasty or feeding difficulty.

Abstract
Laryngomalacia is the term most broadly used to portray the "internal breakdown of structures of supraglottis of the larynx at the time of inspiration. It is often associated with stridor during inspiration, which is of a high pitch at the time of birth and comes into notice by 14 days. When there is an increase in breathing, stridor worsens, and it is usually position-dependent. Laryngomalacia means the weakening of the larynx resulting in a collapse of the laryngeal cartilages, especially the epiglottis, into the airway. This partially occludes the upper airway during inspiration and causes inspiratory stridor. The exact etiology of the condition is not known. It is a well-known cause of noisy breathing in neonates and infants. The common presentation is a neonate with flushing and high-pitched inspiratory stridor that is usually noticed before 14 days of age. This worsens with breathing and supine positioning and improves in a prone position. Less commonly, it can present with hypoxia, feeding problems, aspiration, and failure to thrive. The condition may increase in severity during early life but usually self-resolves by two years of age. The hiccup-like squeak of laryngomalacia during inspiration is due to unsettled air flowing through the laryngeal passage. The condition is diagnosed with laryngoscopy, and the treatment varies with presentation and severity. Neonates with the uncomplicated disease can be treated expectantly. Those presenting with feeding problems and gastroesophageal reflux will require acid suppression. Severe complications like aspiration, severe airway obstruction, and hypoxia will require surgical treatment, including supraglottoplasty. In cases where the surgical treatment failed, noninvasive ventilation can be advised. The article reviews the various medical and surgical interventions and the management of severe laryngomalacia.

Abstract
Stridor is a high-pitched extrathoracic noise associated with turbulent airflow, commonly associated with respiratory distress in infants. Workup for stridor requires evaluation of the upper-respiratory airway, with severe distress requiring evaluation under anesthesia. The differential diagnosis of stridor depends on location of the obstruction, age of the patient, and acuity of the symptoms. The most common reason is laryngomalacia; most patients can be managed conservatively with resolution of symptoms by 2 years of age. In children who do not improve or have severe disease, supraglottoplasty is the treatment of choice, and the majority will have resolution of stridor postoperatively.

Abstract
Major congenital anomalies are known to play a role in the management and prognosis of airway obstruction. Most studies assess acquired forms of airway obstruction. Data on congenital or otherwise non-acquired forms of airway obstruction is sparse. In this retrospective, single-institution cohort study, we sought to evaluate and compare the patterns of airway obstruction in children with and without major congenital anomalies, and to assess the impact of management and outcome, irrespective of aetiology. Fifty-five patients were included, 23 with and 32 without underlying major congenital anomalies. Multilevel airway obstruction (usually affecting the nasopharynx, oropharynx, and the trachea) was more common in children with congenital anomalies (91% vs. 41%, p < .001). Consequently, these children required more frequent and earlier surgical management, especially tracheostomy and adenotonsillar surgery.Conclusions: Major congenital anomalies are associated with multilevel airway obstruction and poor functional prognosis. A simple clinical definition considering impact of major congenital anomalies on development and growth may help guide management plans following endoscopic evaluation of the entire airway and flanked by multidisciplinary discussions. What is Known: • Children with major comorbidities display increased disease severity and more prevalent multilevel airway obstruction • Previous studies include both children with acquired and non-acquired forms of airway obstruction; therefore, the actual impact major comorbidities in children with non-acquired causes of airway obstruction remain unclear. What is New: • A total of 42% children in this study population had major comorbidities with and impact on growth and/or psychomotor development, with a higher prevalence of multilevel airway obstruction and worse rates of functional improvement/recovery. • Children with major comorbidities require tracheostomy more often and earlier than those without major comorbidities, and remain tracheostomy-dependent for a longer time.

Int J Pediatr Otorhinolaryngol 2022; 152:110984. [PMID: 34838327 DOI: 10.1016/j.ijporl.2021.110984] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Revised: 09/25/2021] [Accepted: 11/10/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVES Laryngomalacia is the commonest cause of stridor in the paediatric population. Whilst usually self-limiting, studies have suggested that the presence of synchronous airway lesions (SALs) might be associated with more severe clinical presentation and additional morbidity. However, evidence in the literature is scarce, contributing to controversy regarding the appropriate investigation and management of children with laryngomalacia. The aim of this study was to explore the prevalence, clinical significance and risk factors of SALs in children with severe, progressive and atypical laryngomalacia symptoms. METHODS Retrospective analysis of the records of all paediatric patients diagnosed with laryngomalacia in a UK tertiary referral centre, over a 2-year period, was undertaken. Data on demographics, comorbidities, management and presence of SALs were collected. RESULTS The study included 130 patients with laryngomalacia. Seventy-eight patients required investigation with microlaryngobronchoscopy (MLB), based on clinical presentation. SALs were identified in 22 patients (28.2%), 6 of which (7.7%) required surgical intervention. The commonest airway lesions included tracheomalacia, bronchomalacia and subglottic stenosis. A correlation between the presence of neurodevelopmental conditions in children and SALs was noted (p value < 0.05). The presence of SALs was not associated with sex, gestational age at birth or other medical comorbidities. CONCLUSION The results of this study allow professionals to counsel families about the utility of MLB in children with severe, progressive and atypical laryngomalacia symptoms and inform management pathways for clinicians not working in airway centres. We support the clinical practice that progressive, atypical or severe laryngomalacia symptoms should prompt consideration of an MLB, to identify potential synchronous airway lesions. Furthermore, we propose that a higher index of suspicion and more thorough investigation might be indicated in children with neurodevelopmental disorders.

Abstract
The current article aims to highlight the varied presentation and management of vallecular cysts. We report three children, aged four years, 11 months and three days, diagnosed with vallecular cyst presenting to the Chacha Nehru Bal Chikitsalaya hospital, New Delhi, India in 2018 and 2019. They were reviewed retrospectively for clinical presentation, diagnostic tools and treatment options. All three cases had respiratory and feeding difficulties. The diagnosis in all of the three cases was made with laryngoscopy (flexible/direct) and imaging. All three patients were treated with the transoral approach aimed at the excision of the cyst using cold instruments. The postoperative period was uneventful. No recurrences were observed during the long-term follow-up. Vallecular cysts should be considered as one of the differentials in children with respiratory distress and dysphagia despite being a rare anomaly. A direct transoral approach is recommended for the excision of the vallecular cyst as it is a safe and reliable method with no recurrences to date.

Abstract
BACKGROUND Laryngomalacia is the commonest laryngeal anomaly and cause of stridor in children. Although most cases are self-limiting, failure to thrive, hypoxaemia or significant apnoeic episodes may warrant surgical intervention in the form of aryepiglottoplasty. Opinion is divided as to the pathophysiological mechanisms involved in the disease process. AIMS AND OBJECTIVES This study explores the aetiology of laryngomalacia by reviewing the histology of aryepiglottoplasty resection specimens. MATERIAL AND METHODS The histology reports of 61 aryepiglottoplasty specimens resected between 1 October 2014 and 31 October 2018 were reviewed. RESULTS Age of patients ranged from 3 weeks to 36 months. 36 patients were male and 25 female. 43 of 61 (70.5%) cases had inflammation, most of which were mild. 3 (4.9%) cases had histological specimens with detectable eosinophils. None of the specimens had signs of granulomatous change, ulceration or calcification. Cartilage was present in the resected specimen in 47 (77%) cases. Over half of these (59.6%) were immature cartilage. CONCLUSION AND SIGNIFICANCE The results suggest a mild concurrent laryngitis/supraglottitis in most cases. Eosinophilia is rare and does not support eosinophilic oesophageal reflux as part of the aetiology. The high proportion of immature cartilage in the specimens supports the theory of chondropathic aetiology.

Abstract
AbstractBackgroundRespiratory distress is recognized as any sign of breathing difficulty in infants. Some congenital anomalies present immediately with airway distress, while others are asymptomatic or discovered later in infancy or childhood. Our objectives are to detect different laryngeal causes of respiratory distress in infants and to measure the relative risk of some variables like age, sex, family history, and other congenital anomalies for developing laryngeal causes of respiratory distress. This observational cross-sectional study was carried out during the period from June 2017 to December 2018 at Children’s University Hospital. The study included 80 infants who presented with respiratory distress and admitted to the hospital. All patients subjected to a detailed history from their parents and full general and ENT examinations. X-ray, MSCT neck or direct laryngoscope were carried out in selected cases.ResultsAs regard age, 58% of cases were between 1–6 months, 28% of cases between 6 months and 1 year, and 14% between 1–2 years. Laryngeal causes of respiratory distress among infants were distributed as follow: 70% laryngomalacia, 18% subglottic stenosis, 8% laryngeal web, and 4% of cases were caused by vocal fold paralysis (VFP). The laryngeal causes of respiratory distress did not reveal any statistically significant difference among different age groups or between both genders (P = 0.257, 0.286; respectively). Also, there was no statistically significant difference between infants with positive family history and those without as regard the laryngeal causes of respiratory distress (P = .378).ConclusionThe majority of respiratory distress cases (58%) were between 1–6 months. Bivariant analysis of variables age, sex, family history, and other congenital anomalies showed that they were not potent risk factors for developing laryngomalacia, subglottic stenosis, laryngeal web, and vocal fold paralysis. Laryngomalacia represented the commonest cause of respiratory distress (70%) followed by subglottic stenosis (18%), then laryngeal web (8%), and finally the vocal fold paralysis represented the least percentage (4%). Apart from laryngomalacia, the percentages of other causes seem to vary according to sample size and geographic area of study. So, being familiar with the common causes of respiratory distress in a given region is very essential in order not to miss a potentially life-threatening diagnosis.

Abstract
This study evaluated the hospital course for neonates and older infants with a diagnosis of laryngomalacia (LM). Data came from the 2016 Kids' Inpatient Database of the Healthcare Cost Utilization Project. A total of 6537 children aged <1 year with a diagnosis of LM (International Classification of Diseases, 10th Revision, code Q31.5) were identified: 2212 neonates and 4325 non-neonates. Neonates had a higher mortality rate, 1.31% versus 0.72% in older infants, had more diagnoses (median 9 vs 7) and procedures (mean 85.24 vs 21.83), longer length of stay (median 10 vs 4 days), and higher total charges (median US$65 722 vs US$25 582). A total of 23.3% of neonates born during the admission and diagnosed with LM had undergone laryngoscopy. Second airway lesions were present in 12.33% of neonates and 15.77% of older infants. It appears that neonates are being discharged with a diagnosis of LM without laryngoscopy. Neonatal intensive care unit and newborn nursery policies should require visualization of the larynx prior to diagnosis of LM.

Abstract
OBJECTIVES The primary aim of this study was to identify the ease and safety of office-based lower airway endoscopy (OLAE) in patients with and without comorbidities. In addition, we identified the most common indications for OLAE and the associated diagnosis. METHODS A retrospective review on 567 patients and 706 in-office flexible fiberoptic procedures was performed. Using a previously established grading system, the ease of visualization of the subglottis, trachea, and carina was assessed, in addition to the overall ease of the exam. RESULTS Four hundred and eighty-eight videos were available for review. Of those, 105 videos included an OLAE, accounting for 21.5% of all procedures. Laryngomalacia was the most common diagnosis in 35 of 105 (36%) OLAE. For all laryngomalacia cases, the overall ease was found to be on average 2.15 (standard error 0.12). Fisher exact testing showed a statistical significance in the ability to visualize the trachea between the types of Laryngomalacia (LM) (P = .035). Fisher exact testing was performed comparing LM types I, II, or III, and combined types of LM; no statistical difference was found between groups. In 4.76% of OLAE procedures, a subglottic pathology was diagnosed. Comorbidities were found in OLAE 26 of 105 patients. There were no complications identified. CONCLUSION We found OLAE more challenging than previously reported. OLAE of combined types of laryngomalacia was subjectively more difficult, but this difference did not reach statistical significance. OLAE continues to be a safe alternative to operative laryngoscopy in pediatric patients and appears safe in those with comorbidities when precautions are taken. LEVEL OF EVIDENCE 4.

Abstract
AbstractObjectives:Supraglottoplasty for the treatment of laryngomalacia has little current evidence regarding post-operative care. Our study aimed to: (1) retrospectively assess what proportion of patients required paediatric intensive care unit level of care; (2) identify pre-operative predictive factors common to these cases; and (3) report patient outcomes at six weeks’ follow up.Methods:A 10-year retrospective case series analysis was conducted of all patients diagnosed with laryngomalacia and subsequently treated with supraglottoplasty. Paediatric intensive care unit level of care was defined as the need for intubation or tracheostomy, positive pressure ventilation, multiple doses of nebulised adrenaline, and oxygen dependency beyond 12 hours.Results:Forty-two patients (19 males, 23 females) were identified; 28.5 per cent of cases met our criteria for paediatric intensive care unit level of care. A low pre-operative oxygen saturation was the only significant risk factor that predicted a future need for paediatric intensive care unit level of care (p = 0.0008).Conclusion:This is the first study published in the UK to suggest the importance of pre-operative oxygen saturation as a predictor of a future need for paediatric intensive care unit level of care.

Abstract
Robin sequence (RS) is a commonly encountered triad of micrognathia, glossoptosis, and airway obstruction, with or without a cleft palate. The management of airway obstruction is of paramount importance, and multiple reviews and retrospective series outline the diagnosis and treatment of RS. This article focuses on the multidisciplinary nature of RS and the specialists’ contributions and thought processes regarding the management of the RS child from birth to skeletal maturity. This review demonstrates that the care of these children extends far beyond the acute airway obstruction and that thorough monitoring and appropriate intervention are required to help them achieve optimal outcomes.

Abstract
Objective The aim of this study is to analyse the clinical symptoms, follow-up and treatment properties of the laryngomalacia patients that we encountered between 2009 and 2014. Methods Records of 81 laryngomalacia patients who were followed up in our clinic between 2009 and 2014 were retrospectively analysed. Patients' gender, age, time of onset of the symptoms, chief complaints, other co-existing congenital laryngeal anomalies and treatment and follow-up properties were evaluated. Results Of the 81 patients, 48 were male and 33 were female, and the mean age was 4.9 months. The average period of follow-up was 12.1 months. The chief complaints at the time of admission were stridor (100%) and episodic cyanosis with feeding (27.16%). Symptoms of 75 patients were resolved at an average of 8.2 months with conservative treatment. Three patients underwent supraglottoplasty. Tracheotomy and posterior cordotomy was performed for a patient with co-existing vocal cord paralysis. Additional tracheotomy was necessary for a patient with pulmonary co-morbidities and for another with co-existing subglottic stenosis. Conclusion Laryngomalacia is the most common cause of stridor in infants. The majority of laryngomalacia patients can be managed conservatively by close follow-up. For patients in whom respiratory and feeding problems persist or growth retardation develops, surgical treatment is performed. Tracheotomy may be necessary for a small group of patients with additional diseases.

Abstract
To review the outcomes of laser supraglottoplasty performed in children with symptomatic laryngomalacia and determine the factors influencing them. We retrospectively reviewed the medical records of patients who underwent laser supraglottoplasty for symptomatic laryngomalacia at the Lausanne University Hospital from November 2001 to November 2014. We examined the patient's demography, symptoms, comorbidities, type of laryngomalacia, synchronous airway lesions, and final outcomes. Seventy-nine patients were included in this study; median age at the time of surgery was 12.7 months. 55.7 % of the cases had comorbidities, 22.8 % of the patients were premature and synchronous airway lesions were present in 32.9 % of the cases. The different morphological types of laryngomalacia (I-III) were seen in 26.6, 62 and 11.4 % of the patients, respectively. Overall, operation specific success rate of laser supraglottoplasty was 86.1 %. Failures in 11 (13.9 %) of the 79 cases required 15 revision procedures. Success rates for patients with associated comorbidities, synchronous airway lesions, neurological disorders and prematurity were 81.8, 76.9, 69.2 and 66.7 %, respectively. Patients with type III laryngomalacia had a limited success rate (66.7 %) as compared to patients with morphological types I and II (90.5 and 87.8 %, respectively). Laser supraglottoplasty is an effective and safe treatment for symptomatic laryngomalacia. Patients with prematurity, type III LM, synchronous airway lesions and associated comorbidities are predisposed to surgical failure.

Abstract
OBJECTIVE To comprehensively review changes in sleep parameters and the success rate of supraglottoplasty for treating obstructive sleep apnea (OSA) in children. In particular, to elucidate treatment modalities and factors affecting treatment outcomes in children with both laryngomalacia and OSA. METHODS The study protocol was registered on PROSPERO (CRD42015027053). Two authors independently searched databases including PubMed, MEDLINE, EMBASE, and the Cochrane Review database. The keywords were "supraglottoplasty," "laryngomalacia," "OSA," "polysomnography," "child," and "humans." Supraglottoplasty served as the primary treatment for OSA or secondary treatment for persistent disease after previous surgeries. Subgroup analyses were conducted for children receiving supraglottoplasty as the primary or secondary treatment for OSA, and for children with and without comorbidities. RESULTS Eleven studies with 121 patients were analyzed (mean age: 3.7 years; 64% boys; mean sample size: 11 patients). After surgery, the mean differences between the pre- and postoperative measurements were a significant reduction of 8.9 events/h in the apnea-hypopnea index (AHI) and an increase of 3.7% in minimum oxygen saturation (MinSaO2; P < 0.05). The overall success rate was 28% according to a postoperative AHI <1 and 72% according to an AHI <5. Children receiving supraglottoplasty as the primary treatment had significantly younger ages (0.6 vs 6.4 years P < 0.001) than those receiving supraglottoplasty as the secondary treatment, but the outcomes were similar (33% vs 19% for a postoperative AHI < 1, P = 0.27; 77% vs 61% for a postoperative AHI < 5, P = 0.233). Moreover, children with comorbidities, compared with those without, had a similar success rate according to a postoperative AHI <1 (25% vs 21%, P = 0.805) and postoperative AHI <5 (62% vs 84%, P = 0.166). CONCLUSIONS Supraglottoplasty is an effective surgery for AHI reduction and MinSaO2 increase in children with OSA and laryngomalacia. However, complete resolution of OSA is not achieved in most cases, and factors affecting treatment outcomes in these children require future studies.

Abstract
Pharyngeal wall inspiratory collapse (PWIC) is a dynamic obstruction of the air column proximal to the glottis during inspiration. Our objectives were to assess PWIC's incidence and its contribution to the symptoms of upper airway obstruction (UAO), and to propose indications for intervention. In a retrospective review of consecutive endoscopic evaluations and clinical data of 108 infants with UAO, PWIC was diagnosed in 50 infants (46%). The most common presenting symptom was apnea (52%). The PWIC was accompanied by 2 to 7 synchronous airway abnormalities, most frequently laryngomalacia (78%). Generalized hypotonia was the most common associated systemic finding (80%). Severe PWIC cases required bi-level positive airway pressure (BiPAP). The severity of PWIC, measured by a newly developed classification, was positively correlated to apnea (p < .05) and the need for BiPAP (p < .054). Spontaneous recovery occurred within 36 months. The incidence of PWIC among infants with UAO is high, and its role in UAO deserves greater recognition. Better diagnosis of PWIC will improve the treatment of UAO.

Abstract
Laryngomalacia is the most common cause of stridor in neonates. It typically presents with inspiratory stridor and is often associated with feeding problems. Severe cases present with stridor, apnea, significant respiratory distress, and failure to thrive. Most patients are managed conservatively and can expect to see symptom resolution by 12-24 months of age. About 10% of patients require surgical treatment for their symptoms. Supraglottoplasty is the surgical technique of choice. Results of this surgery are excellent, and severe complications, such as supraglottic stenosis and aspiration, are uncommon. Supraglottoplasty is less effective in patients with significant comorbidities such as neurologic conditions and syndromes.

Abstract
INTRODUCTION AND OBJECTIVES Laryngomalacia (LM) is the most common cause of congenital stridor. Tradition holds that the majority of patients resolve spontaneously by 12-18 months of age. The objective of this study was to systematically review the literature on the spontaneous resolution of LM and/or its presenting symptoms, in otherwise healthy infants. METHODS Data sources included Medline/PubMed, EMBASE, Scopus, CINAHL, Proquest, Cochrane database, Cochrane Methodology Register, Web of Science Conference Proceedings Citation Index, and ACP Journal Club. Study inclusion criteria included participants with an endoscopic diagnosis of LM, and symptoms of stridor, swallowing dysfunction, and/or snoring/sleep-disordered breathing, that documented subjective or objective resolution endpoints. Surgical series, case reports, and narrative reviews were excluded. Studies with insufficient follow-up (<3 months), and patients with comorbidities without subgroup analysis were excluded. Two independent reviewers extracted follow-up duration, rate of retention, time to resolution of LM, and method of documentation of resolution. RESULTS Of the 1146 articles identified, three met inclusion/exclusion criteria (n=411 patients). All were retrospective and used stridor resolution as the only endpoint. Resolution rate was 89%, with time to resolution ranging from 4 to 42 months. Level of evidence was low, and studies suffered from lack of follow-up, and no objective endpoints. Meta-analysis was not possible. CONCLUSIONS Endoscopic evidence of the natural history of laryngomalacia and its resolution is lacking. Low level of evidence supports that stridor and respiratory distress resolve, but the range of the time to resolution and rate of resolution is wide. Other clinical manifestations have not been studied. Prospective longitudinal trials are required to better understand the natural history.

Abstract
Laryngomalacia is the most common cause of stridor in neonates and infants. Associated feeding difficulties are present in approximately half of the children. A definitive diagnosis can generally be made with flexible fiberoptic laryngoscopy. The disorder is most often self-limited with resolution of symptoms within the first 24 months of life, and the majority of children can thus be managed conservatively. The approximately 5%-20% of children with severe or refractory disease may require more aggressive intervention, most commonly in the form of trans-oral supraglottoplasty [1,2]. High success rates and a low rate of complications have been reported for this procedure in otherwise healthy children. Children with syndromes or medical comorbidities are more likely to have complications or persistent symptoms after supraglottoplasty and may require additional interventions.

Abstract
BACKGROUND Laryngomalacia (LM) is the most common congenital anomaly of larynx that causes stridor in children. We evaluated the efficacy of epiglottic suture and laser epiglottopexy for treatment of infants with severe LM. METHODS Surgical intervention was performed in 19 patients with severe LM, after the diagnosis was established using flexible laryngotracheobronchoscopy. Five patients had isolated type 1 LM, and 14 patients had a combination of type 1 and 3 LM. Indication for surgical treatment was the presence of LM with at least one of the following: malnutrition (body mass index [BMI] Z score < -2 SD), dysphagia or symptoms of gastroesophageal reflux and mean oxygen saturation (SaO2 ) <92% with oxygen desaturation index (ODI) > 3. RESULTS Epiglottic suture was performed in 11 patients, and laser epiglottopexy in eight, at mean age 3.95 ± 2.4 months. Rate of operation was 2.2-fold greater for more severe anomaly (combination of type 1 and 3 LM) than for isolated type 1. At 6 month follow up symptoms had gradually improved, as well as nutritional status, with increase of mean BMI Z score from -3.7 to -0.9 (P < 0.01). Mean preoperative SaO2 was 89.4 ± 4.3% with mean ODI of 5.8. At 6 month follow up, mean SaO2 was 96.7 ± 1.1%, and mean ODI was 1.2 (P < 0.01). CONCLUSIONS Epiglottic suture and laser epiglottopexy are efficient surgical techniques that lead to significant improvement of symptoms, oxygenation and nutritional status in patients with LM.

Abstract
OBJECTIVES To analyze the characteristics and the associated medical co-morbidities in children with synchronous airway lesions (SALs) found during rigid bronchoscopy. METHODS Retrospective case series and chart review of patients who were found to have more than one airway lesion after undergoing airway evaluation via rigid endoscopy at a tertiary care pediatric hospital between 2001 and 2011. Patient demographics, presence of associated non-airway pathologies, and the number and types of airway lesions were collected. For analysis, airway lesions were classified based on the anatomical subsites involved (supraglottic, glottic, subglottic, tracheal and bronchial). RESULTS Out of 592 rigid bronchoscopies performed, there were 73 cases with SALs (12.3%). Of these, only 20% of patients were term infants without associated congenital anomalies. Over 70% of patients with SALs have combinations of lesions involving the trachea, subglottis and supraglottis. Neurological anomalies and GERD were both independently associated with a three-time increase in the odds of having synchronous involvement of these three anatomical subsites (OR 3.15, 95% CI 1.06-9.41; OR 3.0, 95% CI 1.05-8.50, respectively). Glottic lesions were present in 28.7% of patients. Prematurity and cardiac anomalies were both associated with tendency of doubling the odds of glottic lesions (OR 2.34, 95% CI 0.84-6.52; OR 2.0, 95% CI 0.76-5.60, respectively). Overall, almost 10% of newly diagnosed lesions in context of SALs required an additional intervention. CONCLUSIONS The majority of patients with SALs are either born prematurely or have associated congenital anomalies. In SAL patients with associated neurological anomalies or GERD, the lesions are more likely to be localized to the supraglottis, subglottis and trachea whereas prematurity and cardiac anomalies could both be increasing the odds of a glottic lesion. High suspicious index should be kept in mind when rigid bronchoscopy is performed to not miss an associated lesion.

Abstract
OBJECTIVES Office-based lower airway endoscopy (OLAE) is not a widespread practice in children due to concerns about its safety and efficacy. In 2003, we reported on OLAE in 105 children presenting with airway symptoms and found it both safe and effective as a diagnostic tool. The current study is a follow-up to the 2003 study that reports on an additional 122 pediatric patients who received OLAE with special attention to the safety and efficacy of the procedure. METHODS A retrospective review at a tertiary-quaternary pediatric institution of 122 consecutive pediatric patients in which an airway lesion, by history and initial physical exam, was determined to be present at the level of the supraglottic larynx to the carina. In all patients, airway endoscopy was performed in the office using flexible fiberoptic laryngoscopy (FFL) and the endoscope was passed beyond the glottis to assess the lower airway, including the subglottis, trachea, and carina. The diagnoses were recorded and the number of times each diagnosis was encountered as well as the percent of patients who had each diagnosis was calculated. All cases requiring operating room procedures for further diagnosis or therapy were assessed for office-based and operating room diagnostic agreement. The ease of performing the lower airway assessment and the ease with which the subglottis, trachea, and carina were visualized were graded. An assessment for complications was also performed. RESULTS There were no complications with OLAE in any of the 122 patients. The percent of patients rated as having good visualization of anatomic structures were: 97% for visualization of the subglottis, 98% for visualization of the trachea, and 92% for visualization of the carina. In 93% of the cases the procedure was easily performed. There was excellent correlation between OLAE and operative endoscopy. CONCLUSION OLAE continues to be a safe, efficacious, and cost-effective tool for the diagnosis of lower airway pathology in pediatric patients.

Anderson de Moreno LC, Matt BH. The effects of prematurity on incidence of aspiration following supraglottoplasty for laryngomalacia. Laryngoscope 2014; 124:777-80. [PMID: 24375071 DOI: 10.1002/lary.21855] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2010] [Accepted: 03/22/2011] [Indexed: 11/09/2022]
Abstract
OBJECTIVES To determine if patients who were born premature have a higher incidence of aspiration following supraglottoplasty compared to patients born full term. STUDY DESIGN Retrospective study. METHODS Two thousand three hundred sixty (2360) patient charts from Riley Hospital for Children were reviewed retrospectively. Patients had already been treated for laryngomalacia with supraglottoplasty by Dr. Bruce Matt. Estimated weeks gestational age at birth was recorded for each patient. Prematurity was stratified as mild (32-36 weeks gestational age [WGA]), very (28-31 WGA), or extremely (<28 WGA). Patients were excluded from the study if they had suspected aspiration with chronic cough, pneumonia, chronic lung disease, or documented aspiration prior to supraglottoplasty. RESULTS As previously shown, 75 patients (3.2%) had aspiration following supraglottoplasty. Twenty of these patients were preterm infants at birth. The rate for aspiration following supraglottoplasty for former premature infants was statistically significant (5.9%, odds ratio = 2.3, P = .0032). CONCLUSIONS Children who were born premature have a higher rate of postoperative aspiration following supraglottoplasty; however, supraglottoplasty should still be considered as treatment for laryngomalacia as the rate is still relatively low (5.9%).

Nasal CPAP therapy for infants with congenital stridor. Sleep Breath 2013; 2:85-97.

Abstract
Ten infants at ages from 1 to 5 months (1st and 2nd trimenon) suffering from congenital inspiratory stridor were examined, dependent on the respective severity of their stridorous phenomenons each, either clinically or/and endoscopically or/and polygraphically, for differentiation of the diagnoses and for assessment of their needs of nCPAP therapy.With the help of nCPAP it is possible to successfully treat even one-month-old babies who suffer from laryngomalacia. The therapy results in effective alleviation of the thorax recession, reduction of funnel chest development, stabilization of SaO2 around 95%, almost complete disappearing of the stridor through laryngeal functional stabilization and the normalization of the increased heart rate. Also to be emphasized is improvement of the sleep which is characterized by remarkably reduced motility. With nCPAP therapy the stridorous symptomatology is reduced within shorter time than even less severe phenomenons disappear in untreated children. By this therapeutic approach intubation, tracheotomy or laryngeal surgery can be avoided.

Abstract
Laryngomalacia is the condition responsible for 75% of the cases of stridor in children aged up to 30 months, in which there is supraglottic collapse during inhalation. Inspiratory stridor is a characteristic telltale. As many as 20% of the patients are severely affected and require surgery. Supraglottoplasty is the procedure of choice and the presence of comorbidities is the most relevant prognostic factor for surgery success. Objective To describe a series in a tertiary pediatric hospital, its success rates, and surgery prognostic factors. Method This retrospective cohort study enrolled 20 patients submitted to supraglottoplasty between July 2007 and May 2011. Results Thirteen (65%) patients were males; mean age at the time of the procedure was 6.32 months. Endoscopic examination showed that 12 subjects had combined forms of laryngomalacia, 40% had associated pharyngomalacia, and three also had tracheomalacia. Thirteen subjects had isolated laryngomalacia and seven had gastroesophageal reflux disease. Fifteen (75%) patients underwent aryepiglottic fold resection. After the procedure, eleven patients were asymptomatic and two required tracheostomy. Presence of comorbidities was the strongest predictor of unfavorable postoperative outcome (p = 0.034). Conclusion Supraglottoplasty is a safe therapeutical procedure for select patients with laryngomalacia.

Abstract
Laryngomalacia is defined as collapse of supraglottic structures during inspiration. It is the most common laryngeal disease of infancy. Laryngomalacia presents in the form of stridor, a high-pitched, musical, vibrating, multiphase inspiratory noise appearing within the first 10 days of life. Signs of severity are present in 10% of cases: poor weight gain (probably the most contributive element), dyspnoea with permanent and severe intercostal or xyphoid retraction, episodes of respiratory distress, obstructive sleep apnoea, and/or episodes of suffocation while feeding or feeding difficulties. The diagnosis is based on systematic office flexible laryngoscopy to confirm laryngomalacia and exclude other causes of supraglottic obstruction. Rigid endoscopy under general anaesthesia is only performed in the following cases: absence of laryngomalacia on flexible laryngoscopy, presence of laryngomalacia with signs of severity, search for any associated lesions prior to surgery, discrepancy between the severity of symptoms and the appearance on flexible laryngoscopy, and/or atypical symptoms (mostly aspirations). The work-up must be adapted to each child; however, guidelines recommend objective respiratory investigations in infants presenting signs of severity.

Abstract
Laryngomalacia is the most common laryngeal disease of infancy. It is poorly tolerated in 10% of cases, requiring assessment and management, generally surgical. Surgery often consists of supraglottoplasty, for which a large number of technical variants have been described. This surgery, performed in an appropriate setting, relieves the symptoms in the great majority of cases with low morbidity. However, few data are available concerning the objective results: preoperative and postoperative objective assessment of these infants is therefore necessary whenever possible. Noninvasive ventilation (NIV) may be indicated in some infants with comorbid conditions or failing to respond to surgical management.

Abstract
OBJECTIVE The aim of this study was to describe and compare the airway findings in term and preterm infants with laryngomalacia. METHODS A retrospective review of 130 patients diagnosed as having laryngomalacia at a tertiary referral center between July 2004 and August 2009 was conducted. Medical records were reviewed for demographic data, supraglottic and glottic airway findings, concomitant airway lesions, and the need for intervention. RESULTS The mean gestational age and age at diagnosis was 36 and 15 weeks, respectively. Combined posterior and anterior supraglottic collapse was the most common finding (31%). Posterior collapse alone occurred in 25%, anterior collapse in 14%, and lateral collapse in 10%. Twelve percent of patients had all 3 sites of collapse. Forty-one percent of patients had a secondary airway lesion, with tracheomalacia being the most common. Preterm infants had significantly higher rates of reflux and more sites of collapse than did term infants (P < .0001). Eight patients required an intervention for their symptoms. CONCLUSIONS Children with laryngomalacia tend to have more than 1 area of supraglottic collapse, and more than one third have a secondary lesion. All patients who required an intervention had more than 1 area of collapse, and 63% of these patients had a secondary airway lesion. Our high incidence of secondary lesions is similar to recent reports.

Abstract
The aim is to determine clinical characteristics, flexible bronchoscopy (FB) findings including associated airway abnormalities and other conditions, treatment modalities and long term follow-up of children with congenital stridor. Medical records of children, who underwent FB for the evaluation of stridor between 1 January 2004 and 31 December 2009 were retrospectively reviewed. Demographic characteristics, symptoms and physical examination findings at presentation, FB findings, follow-up data including the time to resolution of symptoms and treatment modalities, presence of associated conditions were assessed. 109 children were enrolled to the study. Laryngomalacia was the most common etiology for stridor. Laryngomalacia was isolated in 37 patients and 54 patients had secondary airway lesions (SALs). Diagnoses other than laryngomalacia such as subglottic hemangioma, subglottic web, isolated tracheomalacia were found in 18 patients. In 90 % of patients, stridor resolved before 3 years of age without any surgical intervention and there was no significant difference in terms of the persistence of stridor between patients with isolated laryngomalacia and associated SALs. Duration of stridor was significantly longer in both patients with neurological abnormalities and reflux symptoms. Surgical procedure was performed in 19 of the patients. There is a high incidence of SALs in patients with laryngomalacia. FB is helpful for identifying anomalies requiring surgical treatment.

Abstract
OBJECTIVES Rapid anatomical evaluation is essential to establish the severity of cases with upper respiratory obstruction and to define the degree of respiratory distress. Detailed airway endoscopy is required in most patients, not only for diagnosis, but also to treat the condition. In this study, as two of the largest paediatric pulmonology centres in Turkey, we reviewed the data of our bronchoscopy patients, and aimed to document the upper airway abnormalities that we detected during these procedures. PATIENTS AND METHODS A retrospective analysis was made of the records of 1076 paediatric cases with pulmonary/airway disease who had undergone flexible bronchoscopy between 2007 and 2011. RESULTS Upper airway malacia disorders were the most common (79.6%, n=259) bronchoscopic findings detected in the patients. The other most common pathologies were laryngeal edema (12.9%, n=42), external tracheal compression (12.3%, n=40), subglottic stenosis (4.0%, n=13), tracheal stenosis (2.8%, n=9), and vocal cord paralysis/irregularity (2.8%, n=9). The mean duration of symptoms was shortest in patients with vocal cord paralysis, and longest in patients with tracheal nodules (p<0.001). CONCLUSION Paediatricians should keep in mind the possibility of malacia disorders and other congenital and acquired upper airway abnormalities in children with chronic respiratory problems. Diagnosis of underlying diseases, as soon as possible, permits the withdrawal of antibiotics or antiasthmatic drugs often used unnecessarily for long periods to treat these children.

Abstract
Objective. To document the prevalence of secondary airway lesions (SALs) among children with laryngomalacia (LM). Study Design. A cross-sectional observational study. Setting. Single practice in a tertiary care pediatric facility. Subjects and Methods. Patients diagnosed with LM were initially identified from a prospectively kept surgical database. Patients with cardiac/large-vessel malformations, prematurity, repeated or prolonged intubations, acute infections, or prior airway surgery were excluded. Only children who had a full examination of the airway were included. Other associated diagnoses along with demographics, surgical intervention, and type of LM were included. Results. Over an 8-year period, 1112 patients underwent laryngoscopy and bronchoscopy. A total of 108 consecutive cases were diagnosed with LM (78 primary diagnosis and 30 secondary diagnosis). After excluding 17 with disorders associated with large airway disease, 91 LM patients were included. The mean age was 553.23 days (ranging between 5 days and 15 years); 60 were boys and 31 were girls. The prevalence of SALs was 7.7% (95% confidence interval, 7.65-7.76; 7 children; 4 subglottic stenosis, 4 tracheomalacia, 1 bronchomalacia, and 1 choanal atresia). Fifty-nine patients underwent supraglottoplasties, while 1 patient had a tracheostomy. Conclusions. After accounting for conditions known to be associated with large airway lesions, the prevalence of SALs associated with laryngomalacia was much less than previously reported. The authors hypothesize that the upper-end figures are a reflection of highly select cohorts and the inclusion of patients with other pathology known to be associated with subglottic stenosis, tracheomalacia, and bronchomalacia and low thresholds for diagnosing mild subglottic stenosis.

Abstract
Stridor is the sound caused by abnormal air passage during breathing. The cause of stridor can be located anywhere in extrathoracic airway (nose, pharynx, larynx, and trachea) or the intrathoracic airway (tracheobronchial tree). Stridor may be acute (caused by inflammation/infection or foreign body inhalation) or chronic. It may be congenital or acquired. Stridor is a sign from which the underlying cause must be sought; it is not a diagnosis. The role of the pediatrician faced with a child or infant with noisy breathing is: (1) to determine the severity or respiratory compromise and the need for immediate intervention (to prevent respiratory failure); (2) to decide based upon history and clinical examination whether a significant lesion is suspected and, in the latter situation, to refer the child to an ENT surgeon for an upper and lower airway endoscopy; (3) to understand the consequences and management strategies of the underlying lesion and to collaborate with colleagues from related disciplines for follow-up and subsequent management of the child.

Abstract
We conducted a prospective analysis to independently observe the initial opinion of: (1) consulting pediatric residents (postgraduate year 2 [PGY-2]), (2) corresponding considting attending physicians (general pediatric or pediatric emergency medicine) physician, and (3) consulting otolaryngology PGY-2 residents when assessing patients for “noisy breathing.” Each was asked to define the type of noisy breathing present and to formulate a diagnosis based on a limited set of choices. The final diagnosis was determined by a single attending pediatric otolaryngologist (S.E.S.) at the completion of the diagnostic workup. The accuracy for characterization of breath sounds for the pediatric residents, attending pediatricians, and otolaryngology residents were 26.1%, 23.5%, and 98.6%, respectively. The positive predictive values for the determination of diagnosis were 71.6%, 69.4%, and 76.6%, respectively. These findings indicate that pediatric residents and attending pediatricians may be deficient in their ability to characterize the breath sounds commonly seen inpatients with noisy breathing. Further education of pediatricians may lead to a more accurate diagnostic evaluation of a child with noisy breathing.

Abstract
Objectives: We sought to determine the incidence of secondary airway lesions in infants with laryngomalacia and to compare the incidences of these concomitant airway lesions in infants with severe, moderate, and mild laryngomalacia; to determine whether infants with mild or moderate laryngomalacia have a higher incidence of surgical intervention when a secondary airway lesion is present; and to determine whether the incidence of gastroesophageal reflux disease (GERD) is affected by the presence of a secondary airway lesion. Methods: We performed a retrospective review of a database consisting of 201 infants with a diagnosis of laryngomalacia treated at a pediatric tertiary referral center between June 1998 and June 2003. Data pertaining to demographic information, severity of laryngomalacia, presence of secondary airway lesions, and diagnosis of GERD were collected and analyzed. Results: Of the 201 infants, 104 (51.7%) were found to have a secondary airway lesion. Subglottic stenosis was found in 38.8%, and tracheomalacia in 37.8%. Of the infants with severe laryngomalacia, 30 (79%) had a diagnosis of a secondary lesion, compared with 51 (61.5%) of those with moderate and 23 (28.8%) of those with mild disease. Among infants with mild or moderate disease, those with secondary airway lesions were more likely to require surgical intervention than were infants without secondary airway lesions (27% versus 5.6%; p = 0.0002). There was no difference in the rates of secondary airway lesions in infants managed with supraglottoplasty versus tracheotomy. The incidence of GERD in this patient population was 65.6%. Infants with a secondary airway lesion were more likely to have GERD than were those without a secondary airway lesion (84.6% versus 45.4%; p < 0.0001). Conclusions: The incidence of secondary airway lesions in our population of infants with laryngomalacia was higher than those previously reported. The severity of disease correlated with the diagnosis of a secondary airway lesion. Secondary airway lesions lead to an increased incidence of surgical intervention and GERD in infants with laryngomalacia.

Abstract
OBJECTIVES/HYPOTHESIS To determine if supraglottoplasty (SGP) is effective in reversing abnormal respiratory parameters in children with laryngomalacia and obstructive sleep apnea (OSA). STUDY DESIGN Retrospective case series at a tertiary referral children's hospital. METHODS Ten patients with laryngomalacia and OSA as documented by polysomnography underwent SGP between 2005 and 2007. Data collected included age, findings on flexible and rigid endoscopy, type of procedure performed, and postoperative course. The postoperative polysomnographies were reviewed to identify changes in obstructive apnea index, obstructive apnea/hypopnea index, respiratory disturbance index, and low arterial oxygen saturation (O2 nadir) after SGP. RESULTS All 10 patients were successfully extubated after SGP. There were no peri- or postoperative complications, and no patient required a subsequent airway procedure. Each patient had a postoperative nocturnal polysomnography performed after SGP at 11 weeks (range 2-29 weeks). Caregivers reported mild improvement (10%), significant improvement (70%), and complete resolution (20%) of stridor and nocturnal snoring at a follow-up visit 4 weeks after discharge. Marked improvements were observed in obstructive apnea index, obstructive apnea/hypopnea index, respiratory disturbance index and O2 nadir, all of which were statistically significant (P < .05). CONCLUSIONS Polysomnography should be considered in the initial evaluation of infants with moderate laryngomalacia to rule out OSA. SGP is an effective treatment for infants with laryngomalacia and OSA. The significant benefits of the procedure outweigh thelow morbidity. Improvement after surgery was reliably confirmed by polysomnography in this study.

Abstract
OBJECTIVE Laryngomalacia is the most common cause of congenital stridor. Laryngomalacia may be associated with other structural and functional airway lesions. While previous studies suggested a 10-45% rate of synchronous airway lesions (SALs), the exact rate and it's clinical significance is unknown. The purpose of this study was to determine the prevalence of SALs below the glottic level in congenital laryngomalacia, and to investigate possible relations with other clinical findings. METHODS A cohort of 228 infants with congenital stridor who underwent fiberoptic flexible bronchoscopy (FFB) was analyzed. Data was collected from the hospital records. All procedures were reevaluated from the video recordings. RESULTS SALs below the vocal cords were observed in 7.5% of the case (17/228). The most common SAL was tracheal bronchus followed by tracheomalacia and stenosis of the left main bronchus. No correlation was found between the presence of a SAL below the vocal cords and any other medical condition except for neurodevelopmental disorders. Except for one patient, all cases with SAL did not have any clinical symptoms or signs that would have suggested an accompanying airway lesion. CONCLUSIONS The rate of SALs in infants with congenital stridor due to laryngomalacia is low and most of the additional lesions are benign. The yield of discovering clinically significant SALs below the glottic level is low and the routine search for a synchronous lesion below the vocal cords should be questioned. Except for underlying neurodevelopmental problems, no clear risk factors for the existence of SALs were identified.

Abstract
OBJECTIVE To evaluate the prevalence of synchronous airway lesions (SALs) and associated anomalies in children with laryngomalacia requiring rigid endoscopic evaluation, the clinical significance of such lesions, and safety and outcome of selective rigid endoscopy. SETTING National Children's Hospital. DESIGN AND METHOD Retrospective analysis. The records of all children diagnosed with laryngomalacia who underwent rigid endoscopy were identified from the surgical database over a 4-year period. OUTCOME MEASURES Age at presentation, signs and symptoms at time of presentation, presence of associated neurological and/or congenital anomalies (ANCAs), presence of synchronous airway lesions, need for surgical intervention, complications and time to resolution of symptoms were assessed. RESULTS There were 26 children in the study. The mean age at presentation ranged from 0 to 10 months of age. One child (3.8%) required surgical intervention for severe isolated laryngomalacia. Seven children (26.9%) had at least one SAL identified. Of these, six (85.7%) were previously diagnosed on flexible fibreoptic laryngoscopy (FFL). Two of the seven children with SALs required surgical management of the SAL. Prematurity and ANCAs prolonged hospital stays in these children. However, the presence of SALs did not affect the length of hospital stay or the time to resolution of symptoms. Symptom resolved in all children by 3 years of age, whether or not SALs or ANCAs are present. There was no adverse outcome in the study group. CONCLUSION Despite having indications for rigid endoscopy, many children with laryngomalacia do not have SALs, which even when present, are rarely clinically significant. SALs and ANCAs do not impact the time to symptom resolution. The current indications for rigid endoscopy in the evaluation of laryngomalacia are appropriate and safe.

Abstract
Congenital and acquired airway diseases are responsible for upper respiratory distress and stridor in children. In neonatal intensive care units, we have seen increased survival in premature babies, but also a high incidence of airway complications related to intubation, which present as stridor. Aim To review endoscopic findings in children with stridor. Study design a cross-sectional cohort study. Methods A retrospective analysis was done of 55 cases of children with stridor who underwent endoscopic exams, between January 1997 and December 2003. Results 69% were aged below one year. The main indications for endoscopy were post-extubation stridor (63.63%) and evaluation of neonatal stridor (21.82%). Many associated diseases were seen, including lung diseases (60%), neurological condition (45.4%), and GERD (40%). The main endoscopic findings and indications for tracheotomy were subglottic stenosis (27.27%) and airway inflammatory process (21.82%) occurring in children under five years old. Congenital disorders were more frequent in children under age one year. Conclusion Neonatal stridor has many causes; those related to tracheal intubation are more frequent in hospitals that treat more complex diseases. Pediatricians and otorhinolaryngologists should know the main causes of stridor and perform detailed clinical evaluations to determine case severity. The endoscopic examination, must be meticulous.

Abstract
A Laringomalácia é a causa mais comum de estridor na infância, com resolução espontânea até os 2 anos de idade na maioria dos casos. Cerca de 10% dos casos (laringomalácia severa) necessitam de intervenção cirúrgica. O diagnóstico é estabelecido com o exame de videonasofibroscopia, na qual se observa encurtamento da prega ariepiglótica, e/ou excesso de mucosa das aritenóides, e/ou queda da epiglote no sentido ântero-posterior. A etiologia ainda permanece desconhecida. OBJETIVO: Verificar as principais alterações clínicas e anatômicas assim como identificar os principais parâmetros clínicos no acompanhamento e na indicação cirúrgica de pacientes portadores de laringomalácia. FORMA DE ESTUDO: Estudo de coorte transversal. MATERIAL E MÉTODO: Foram incluídos neste estudo 22 crianças com diagnóstico de laringomalácia do ambulatório de otorrinolaringologia pediátrica da UNIFESP-EPM, entre janeiro de 2001 a dezembro de 2003, assistidas pelo mesmo examinador. RESULTADOS: Das 22 crianças com diagnóstico de laringomalácia, duas (9,1%) apresentavam laringomalácia severa com depressão torácica (tórax escavado). O estridor inspiratório e o encurtamento das pregas ariepiglóticas foram encontrados em todos pacientes. À polissonografia, nenhuma criança apresentou evento respiratório significativo durante o sono. As duas crianças com laringomalácia severa foram submetidas à supraglotoplastia com secção das pregas ariepiglóticas. CONCLUSÃO: O estridor respiratório e o encurtamento das pregas ariepiglóticas fazem parte preponderante do quadro clínico. A polissonografia não mostrou ser um parâmetro importante, nem para o acompanhamento clínico nem para a indicação cirúrgica, ao contrário da falta de ganho de peso e da presença de tórax escavado. A secção cirúrgica das pregas ariepiglóticas é efetiva e com baixo índice de morbidade.

Abstract
Laryngomalacia is the most frequent cause of stridor in childhood, and in most of the cases, spontaneous resolution occurs by the age of 2 years. Approximately 10% of the cases (severe laryngomalacia) require surgery. This condition is of unknown etiology and its diagnosis is made by fiberoptic laryngoscopy, which shows shortening of the aryepiglottic folds, and/or redundant arytenoid mucosa, and/or anterior-posterior epiglottic prolapse. Aim: Our objective was to verify the main clinical and anatomical affections and to highlight the clinical parameters for clinical follow-up and surgical indication in patients with laryngomalacia. Study design: Transversal cohort study. Material and Method: Twenty-two children diagnosed with laryngomalacia in the Pediatric Otorhinolaryngology of UNIFESP-EPM, from January 2001 to December 2003, whose clinical and surgical follow-up were performed by the same examiner, were enrolled in this study. Results: Out of twenty-two evaluated children, 2 (9.1%) presented with severe laryngomalacia and pectus excavatum (funnel chest). At polysomnography, no child presented any significant respiratory event during sleeping. Those two children with severe laryngomalacia were submitted to supraglottoplasty with resection of the aryepiglottic folds. Conclusion: We concluded that stridor and shortening of the aryepiglottic folds are preponderant in children with laryngomalacia. The polysomnographic exam did not prove to be a good parameter for clinical follow-up, neither for surgical indication. The most important parameters were pectus excavatum and failure to thrive. Supraglottoplasty is effective and has low morbidity rate.

Abstract
OBJECTIVE Although laryngomalacia is a common cause for infantile stridor, few patients eventually go on to require surgical intervention. When surgery is required, the location of tissue excised may vary depending on the endoscopic findings, but only two methods of tissue excision are described-cold knife excision and carbon dioxide laser. We present our experience of using the microdebrider to excise tissue during supraglottoplasty. METHODS Over the last 12 months, patients were identified who had undergone supraglottoplasty, and their final outcomes with regards to resolution of stridor, cor pulmonale, and/or failure to thrive were assessed. A description of the indications for supraglottoplasty and the actual technique utilizing the microdebrider is included. RESULTS Five patients were identified as having undergone a microdebrider-assisted supraglottoplasty. All five had resolution of their stridor following surgery. No new complications such as aspiration or supraglottic stenosis were identified. No revision surgeries were required. The microdebrider was used to trim the aryepiglottic folds and/or redundant arytenoid mucosa in all cases. CONCLUSIONS The microdebrider appears to be a safe and effective tool to remove redundant tissue during supraglottoplasty.

Abstract
We present an 8-day-old female with two admissions for respiratory failure. On the first admission, the diagnosis of Pierre Robin sequence (PRS) and laryngomalacia was made after assessment with chest radiography, echocardiography, and flexible fiberoptic laryngoscopy. Four days after discharge, the child presented with stridor and respiratory distress, and a new cardiac murmur was noted after admission. Repeat echocardiography, with confirmatory direct laryngobronchoscopy, revealed a double aortic arch (DAA) with distal tracheal compression. This case illustrates the necessity of a complete otolaryngic evaluation, including direct laryngobronchoscopy, to search for a synchronous airway lesion in any neonate with severe respiratory distress associated with stridor.

Abstract
Vallecular cyst is a rare but dangerous cause of stridor in neonates and young infants. Without recognition and proper therapy, the resulting airway obstruction can lead to serious morbidity and mortality. We herein report a young infant with a vallecular cyst synchronous with laryngomalacia and gastroesophageal reflux. The infant initially presented with signs and symptoms mimicking more benign laryngomalacia. Diagnosis was delayed with accompanying failure to thrive. The cyst was revealed by a barium esophagogram and confirmed by flexible bronchoscopy. Laryngomicrosurgery with CO(2) laser not only removed the cyst, but resolved the co-existing laryngomalacia and gastroesophageal reflux as well. After surgery, the infant was symptom free and exhibited a steady weight gain. There was no recurrence during 1 year of follow-up. We have reviewed the literature for this rare and potentially devastating lesion.
