Changing indications and antenatal prognostic factors for ex-utero intrapartum treatment procedures.

OBJECTIVE: In cases of suspected neonatal airway obstruction, the ex-utero intrapartum treatment (EXIT) procedure is used to secure the airway while a fetus remains on placental circulation. We report indications and outcomes from all EXIT procedures at a tertiary obstetric unit between 1997 and 2020. METHOD: Retrospective cohort study with data collected from maternal and neonatal medical records. RESULTS: Indications for EXIT procedures were micrognathia (n = 7), lymphatic malformations (n = 5), cervical teratomas (n = 4), goiters (n = 2), and intra-oral epulis (n = 1). Infants with a fetal teratoma were delivered earliest due to 75% presenting with preterm premature rupture of membranes or preterm labor. Low birth weight was found in 75% of these neonates; they did not survive 1 year. Intubation at EXIT occurred for 58% (n = 11) of babies, and six neonates required a tracheostomy. In four cases of fetal micrognathia, the inferior facial angle (IFA) was noted to be <5th centile. All but one micrognathia case had polyhydramnios. Of the total cohort, 75% of neonates were alive at 1 year. CONCLUSION: Risks for neonatal demise with EXIT include fetal teratoma, low birth weight, and prematurity. Micrognathia has become an increasingly valid indication for the procedure. The combination of polyhydramnios and IFA <5% correlates well with severe airway obstruction and suggests consideration of EXIT.

Surgically Acquired Vocal Cord Palsy in Infants and Children with Congenital Heart Disease (CHD): Description of Feeding Outcomes.

Impaired swallowing in infants can impact upon the ability to feed orally, often resulting in dependency on supplementary feeding. Such difficulties can lead to an increased burden of care and associated costs. The primary aim of this study was to investigate the impact of vocal cord palsy (VCP), acquired intraoperatively during cardiac surgery, on the feeding outcomes of infants at a tertiary metropolitan children's hospital. An additional aim was to obtain preliminary information on the impact of feeding difficulties in this group on the quality of life of parents and families. A review of 48 patients who had been referred to the speech pathology service was undertaken. Participants presented with heterogeneous cardiac diagnoses, and had an initial Videofluoroscopic Swallow Study (VFSS) at a median corrected age of 3.6 weeks. Sixty percent of participants presented with silent aspiration on VFSS. Thirty percent of participants required supplementary tube feeding more than 6 months post-surgery. Six percent of participants with poor feeding progress and persistent aspiration required further surgical intervention to support nutrition. Findings revealed no significant relationship between participant factors and the presence of feeding difficulties, however, infants with concomitant genetic and syndromic conditions were found to be most at-risk for long-term feeding difficulties. Analysis of informal parent questionnaire responses indicated parents experienced stress and anxiety after their child's discharge. This was noted in regard to their child's feeding, which impacts quality of life across a number of domains. Findings of this study highlight the importance of communicating the potential feeding difficulties to parents of at-risk infants prior to cardiac surgery. This study further highlighted the importance of routine post-operative otorhinolaryngology examinations following high-risk surgeries, as well as speech pathology management for all infants and children identified with VCP. Post-operative input from appropriately trained Speech Pathologists is vital in assisting parents to support and mitigate their child's difficulties through the provision of early intervention for feeding difficulties.

A Prospective Study of the Incidence of Juvenile-Onset Recurrent Respiratory Papillomatosis After Implementation of a National HPV Vaccination Program.

Background: Recurrent respiratory papillomatosis is a rare but morbid disease caused by human papillomavirus (HPV) types 6 and 11. Infection is preventable through HPV vaccination. Following an extensive quadrivalent HPV vaccination program (females 12-26 years in 2007-2009) in Australia, we established a method to monitor incidence and demographics of juvenile-onset recurrent respiratory papillomatosis (JORRP) cases. Methods: The Australian Paediatric Surveillance Unit undertakes surveillance of rare pediatric diseases by contacting practitioners monthly. We enrolled pediatric otorhinolaryngologists and offered HPV typing. We report findings for 5 years to end 2016. Results: The average annual incidence rate was 0.07 per 100000. The largest number of cases was reported in the first year, with decreasing annual frequency thereafter. Rates declined from 0.16 per 100000 in 2012 to 0.02 per 100000 in 2016 (P = .034). Among the 15 incident cases (60% male), no mothers were vaccinated prepregnancy, 20% had maternal history of genital warts, and 60% were first born; 13/15 were born vaginally. Genotyped cases were HPV-6 (n = 4) or HPV-11 (n = 3). Conclusion: To our knowledge, this is the first report internationally documenting decline in JORRP incidence in children following a quadrivalent HPV vaccination program.

Adenotonsillectomy for Obstructive Sleep Apnea in Children.

Obstructed breathing is the most common indication for tonsillectomy in children. Although tonsillectomy is performed frequently worldwide, the surgery is associated with a number of significant complications such as bleeding and respiratory failure. Complication risk depends on a number of complex factors, including indications for surgery, demographics, patient comorbidities, and variations in perioperative techniques. While polysomnography is currently accepted as the gold standard diagnostic tool for obstructive sleep apnea, studies evaluating outcomes following surgery suggest that more research is needed on the identification of more readily available and accurate tools for the diagnosis and follow-up of children with obstructed breathing.

Innominate Artery Pseudoaneurysm Requiring Cartilage Tracheal Repair in a Child.

Mycotic aneurysms are rare but potentially catastrophic. We report a case of an innominate artery pseudoaneurysm in a 4-year-old patient that caused a tracheoinnominate fistula requiring tracheoplasty with a costal cartilage graft and a homograft iliac artery replacement of the diseased innominate artery, with a successful outcome.

Management of Recurrent and Delayed Post-Tonsillectomy and Adenoidectomy Hemorrhage in Children.

OBJECTIVE: To review our experience on post-tonsillectomy and/or adenoidectomy hemorrhage (PTAH) at a tertiary pediatric referral hospital and to evaluate the management and risk factors for recurrent postoperative hemorrhage and for delayed bleeding after day 14. METHODS: A retrospective chart review was performed for all pediatric patients admitted to The Children's Hospital at Westmead for PTAH between July 01, 2014, and June 30, 2019. Patients with recurrent hemorrhage and those with bleeding after day 14 were selected for subanalysis. RESULTS: Of the 291 patients admitted for PTAH, 31 (11%) patients had recurrent postoperative hemorrhage, and 11 (4%) patients had delayed bleeding after day 14. Surgical intervention for cessation of hemorrhage was required in 88 (30%) patients, including 2 patients who required return to the theater more than once. Nine (3%) patients received blood transfusions. The average number of days between bleeding episodes was 4 days. Recurrent postoperative hemorrhage occurred in 8.5% of patients who were managed operatively at their first presentation compared to 11.4% of patients who were managed nonoperatively (odds ratio: 1.1; 95% confidence interval 0.43-2.8). No association was found between abnormal coagulation profile, surgical indication, and risk of delayed postoperative hemorrhage. CONCLUSIONS: Recurrent or delayed postoperative hemorrhage represents a small proportion of children with postoperative bleeding and cannot be reliably predicted. Management of first presentations with either a conservative or a surgical approach is reasonable since the risk of recurrent of PTAH may be unrelated to the choice of management at initial presentation. Careful preoperative counseling of patients and their families is important to help set expectations in the event of PTAH.

International Pediatric Otolaryngology Group (IPOG) consensus on scoring of pediatric Drug Induced Sleep Endoscopy (DISE).

OBJECTIVES: To develop consensus statements for the scoring of pediatric drug induced sleep endoscopy in the diagnosis and management of pediatric obstructive sleep apnea. METHODS: The leadership group identified experts based on defined criteria and invited 18 panelists to participate in the consensus statement development group. A modified Delphi process was used to formally quantify consensus from opinion. A modified Delphi priori process was established, which included a literature review, submission of statements by panelists, and an iterative process of voting to determine consensus. Voting was based on a 9-point Likert scale. Statements achieving a mean score greater than 7 with one or fewer outliers were defined as reaching consensus. Statements achieving a mean score greater than 6.5 with two or fewer outliers were defined as near consensus. Statements with lower scores or more outliers were defined as no consensus. RESULTS: A total of 78 consensus statements were evaluated by the panelists at the first survey - 49 achieved consensus, 18 achieved near consensus, and 11 did not achieve consensus. In the second survey, 16 statements reached consensus and 5 reached near consensus. Regarding scoring, consensus was achieved on the utilization of a 3-point Likert scale for each anatomic site for maximal observed obstructions of <50% (Score 0, no-obstruction), ≥ 50% but <90% (Score 2, partial obstruction), and ≥ 90% (Score 3, complete obstruction). Anatomic sites to be scored during DISE that reached consensus or near-consensus were the nasal passages, adenoid pad, velum, lateral pharyngeal walls, tonsils (if present), tongue base, epiglottis, and arytenoids. CONCLUSION: This study developed consensus statements on the scoring of DISE in pediatric otolaryngology using a modified Delphi process. The use of a priori process, literature review, and iterative voting method allowed for the formal quantification of consensus from expert opinion. The results of this study may provide guidance for standardizing scoring of DISE in pediatric patients.

Lessons Learnt from the COVID-19 Pandemic in Pediatric Otolaryngology.

Purpose of Review: The current COVID-19 pandemic has challenged the international paediatric otolaryngology community: we review its impact in clinical, resource, and human settings. Recent Findings: The SARS-CoV-2 virus, while generally mild in paediatric populations, has caused an increased incidence in severe croup, invasive fungal sinus disease, and multi system inflammatory syndrome (MIS-C). The incidence of other common otolaryngology presentations such as otitis media and tonsillitis has decreased due to quarantine measures. The pandemic has also changed the way in which we work: guidelines for aerosol-generating procedures (AGPs) have changed, digital technology and videoconferencing platforms have flourished, and new pathways of providing healthcare have been developed to minimise footfall and avoid overcrowded waiting rooms. Finally, the importance of personal protective equipment (PPE) to protect healthcare workers and patients cannot be understated, although the mental and physical toll is considerable. Summary: There has been a tectonic shift in paediatric otolaryngology and healthcare globally. Continued adaptability and resilience are required to face these challenges in the coming months. With lessons learnt from managing SARS-CoV-2, we are hopefully well equipped to combat any future pandemics.

Epiglottic repositioning procedure for supraglottic stenosis/collapse.

OBJECTIVES: Supraglottic stenosis/collapse is an uncommon condition. It can be difficult to detect and may be a cause of failed decannulation following tracheostomy. We present a novel technique to correct supraglottic stenosis/collapse. METHODS: We performed a retrospective analysis of the records of patients in whom attempts at decannulation had failed at our center between 2003 and 2007. A subgroup with supraglottic stenosis/collapse with posterior displacement of the base of the epiglottis was identified. Our epiglottic repositioning procedure was performed in these patients. Through an external incision, the epiglottis was divided above the anterior commissure and attached to the superior border of the thyroid cartilage. RESULTS: Eight decannulation failures out of 36 attempted decannulations were identified. Three of these 8 cases involved supraglottic stenosis/collapse due to posterior displacement of the base of the epiglottis. Correction of the supraglottic stenosis/collapse led to successful decannulation in all cases. CONCLUSIONS: Diagnosis-directed laryngoscopy is required to identify this condition. We describe precisely a technique of repositioning the epiglottis to correct supraglottic stenosis/collapse.

Complications and outcomes following open laryngotracheal reconstruction: A 15 year experience at an Australian paediatric tertiary referral centre.

OBJECTIVE: To report on our experience with open pediatric laryngotracheal reconstruction (LTR) with cartilage interposition grafts over the past 15 years and document setbacks and factors that affect postoperative outcomes. METHOD: A retrospective chart review was performed on all pediatric patients who underwent single and double-stage LTR at The Children's Hospital in Westmead between August 2004 and July 2019. The outcomes measured include the overall decannulation rate, rates of postoperative complications, need for subsequent procedures and postoperative functional results (dyspnea, stridor, voice impairment). RESULTS: Between August 2004 and July 2019, a total of 51 open LTRs were performed on 46 patients, with mean age 3.9 years (range 1 month to 12.1 years), including 11 revision operations (11.8%). The most common indication for surgery was subglottic stenosis, followed by bilateral vocal cord motion impairment followed by anterior glottic web. 13 cases (25.5%) were complicated by ventilator associated pneumonia in the postoperative period and 11 patients (21.6%) experienced wound complications ranging from localised wound abscess to wound dehiscence and graft failure. Patients with viral infections had an increased risk of wound dehiscence and graft failure (OR 1.8, 95% CI 1.01 - 3.23). Patients with a greater decrease in albumin in the postoperative period were more likely to have wound complications (OR 1.8; 95% CI 1.17 -2.83). Ten patients failed extubation and required a subsequent tracheostomy. Severity of stenosis, age at time of surgery, history of prematurity and revision LTR were not predictors for need for reintubation and/or tracheostomy after surgery. 23 cases (45.1%) underwent subsequent endoscopic procedures such a balloon dilatation to manage restenosis following LTR. Though 45.7% had a very good outcome, a significant group of 21% had ongoing voice issues. CONCLUSION: Good outcomes were achieved following open LTR for pediatric laryngotracheal stenosis despite postoperative complications. At final follow up, 33 patients (71.7%) had good exercise tolerance with no or mild stridor. Forty-one of the forty-six patients (89.1%) were successfully decannulated.

Sleep and Behavior 24 Months After Early Tonsillectomy for Mild OSA: An RCT.

BACKGROUND AND OBJECTIVES: The Preschool Obstructive Sleep Apnea Tonsillectomy and Adenoidectomy study is a prospective randomized controlled study of children aged 3 to 5 years. This follow-up evaluated postoperative outcomes 24 months after randomization. METHODS: Baseline, 12-month, and 24-month assessments included intellectual ability, polysomnography, audiology, a pediatric sleep questionnaire, the parent rating scale of the Behavior Assessment System for Children, and the Behavior Rating Inventory of Executive Functioning. RESULTS: In total, 117 (55% male) of 190 children, 61.6% of those initially randomly assigned, attended 24-month follow-up; 62 of 99 were assigned T/A within 2 months (eT/A); and 55 of 91 were assigned to T/A after the 12-month follow-up (T/A12). Intellectual ability, our primary outcome, did not differ according to the timing of T/A. Exploratory analyses revealed changes in both groups after T/A, including fewer children having day sleeps (eT/A from baseline 97% to 11%, T/A12 from 36% at 12 months to 9%), improved symptom scores (eT/A 0.62 to 0.25, T/A12 0.61 to 0.26; P < .001), improved behavior T-scores (eT/A 71.0 to 59.9, T/A12 63.6 to 50.5; P < .001), and improved polysomnography (obstructive apnea-hypopnea index eT/A 1.9 to 0.3 per hour, T/A12 1.3 to 0.3; P < .001). The eT/A group revealed temporary postoperative improvement of Woodcock-Johnson III subscales (sound blending and incomplete word scores) and behavioral withdrawal. CONCLUSIONS: T/A for mild obstructive sleep apnea led to large improvements in sleep and behavior in preschool-aged children, regardless of the timing of surgery.

Cognition After Early Tonsillectomy for Mild OSA.

OBJECTIVES: It remains uncertain whether treatment with adenotonsillectomy for obstructive sleep apnea in children improves cognitive function. The Preschool Obstructive Sleep Apnea Tonsillectomy and Adenoidectomy study was a prospective randomized controlled study in which researchers evaluated outcomes 12 months after adenotonsillectomy compared with no surgery in preschool children symptomatic for obstructive sleep apnea. METHODS: A total of 190 children (age 3-5 years) were randomly assigned to early adenotonsillectomy (within 2 months) or to routine wait lists (12-month wait, no adenotonsillectomy [NoAT]). Baseline and 12-month assessments included cognitive and behavioral testing, medical assessment, polysomnography, and audiology. The primary outcome was global IQ at 12-month follow-up, measured by the Woodcock Johnson III Brief Intellectual Ability (BIA). Questionnaires included the Pediatric Sleep Questionnaire, Parent Rating Scale of the Behavioral Assessment System for Children-II, and Behavior Rating Inventory of Executive Function, Preschool Version. RESULTS: A total of 141 children (75.8%) attended baseline and 12-month assessments, and BIA was obtained at baseline and 12-month follow-up for 61 and 60 participants in the adenotonsillectomy versus NoAT groups, respectively. No cognitive gain was found after adenotonsillectomy compared with NoAT, adjusted for baseline; BIA scores at 12-month follow-up were as follows: adenotonsillectomy, 465.46 (17.9) versus NoAT, 463.12 (16.6) (mean [SD]). Improvements were seen for polysomnogram arousals and apnea indices and for parent reports of symptoms (Pediatric Sleep Questionnaire), behavior (Behavior Assessment System for Children behavioral symptoms, P = .04), overall health, and daytime napping. CONCLUSIONS: Structured testing showed no treatment-attributable improvement in cognitive functioning of preschool children 12 months after adenotonsillectomy compared with NoAT. Improvements were seen after adenotonsillectomy in sleep and behavior by using polysomnogram monitoring and parental questionnaires.

Unusual Presentation of Severe Endobronchial Obstruction Caused by Cryptococcus gattii in a Child.

Disease caused by Cryptococcus gattii typically manifests as meningoencephalitis or pulmonary nodules. Endobronchial lesions are rare, and most cases are caused by Cryptococcus neoformans. We describe here a case of endobronchial disease in a child caused by C gattii. The disease spectrum in this patient was notable for the discovery of anti-granulocyte macrophage colony-stimulating factor autoantibodies.

Routine vocal cord mobility assessment post cardiac surgery via median sternotomy approach.

OBJECTIVES: Surgery of the aortic arch carries a risk of injury to the vagus and recurrent laryngeal nerves, particularly in a young child, as these structures lie in close proximity to aortic arch. This study aimed to determine the incidence, symptomatology and natural history of vocal cord dysfunction (VCD) following aortic arch reconstructive surgery through a median sternotomy approach. METHODS AND MATERIALS: Prospective assessment was performed of all consecutive newborns who underwent cardiac surgery for aortic arch surgery via median sternotomy between January 2016 and May 2017 at a tertiary paediatric hospital. All patients underwent post-operative flexible fibreoptic nasolaryngoscopy (FNL) after extubation to assess for the presence of vocal cord dysfunction (VCD). Those with VCD were re-examined at followup. A feeding assessment performed by speech pathologists (SPs) and a video fluoroscopic swallow study (VFSS) were also performed in those with VCD or feeding difficulties. RESULTS: A total of 35 newborns were included in the study. At initial review, left sided VCD was demonstrated in 65.7% of patients (n=23). Significant associations with VCD were younger age (3.0 versus 6.5 days, p=0.041) and a weak or absent cry (Relative Risk=16.4, 95%CI 3.8-47.8, p<0.001). 52.5% (n=11) of patients with VCD had evidence of aspiration on VFSS. There was no significant difference in intensive care unit stay or overall hospital stay between patients with VCD compared to those without (33.0 days vs 28.8 days, p=0.73; 52.5 vs 45.9, p=0.72.) Infants with either proven VCD or a weak cry were more likely to be discharged home with a nasogastric (NG) tube (RR=4.67, p= 0.048; RR=7.00 p=0.022 respectively). At followup after 106 days, complete resolution was seen in 100% patients with partial VCD and 61.5% with complete VCD. CONCLUSIONS: VCD is a common complication following neonatal aortic arch surgery, although most experience resolution of symptoms over time. The authors recommend post-operative laryngoscopy in all patients should be routine, and particularly those with a weak cry.

International Pediatric Otolaryngology Group (IPOG) Consensus Recommendations: Congenital Cholesteatoma.

OBJECTIVE: To provide recommendations to otolaryngologists and allied physicians for the comprehensive management of children who present with signs and symptoms of congenital cholesteatoma. METHODS: A two-iterative Delphi method questionnaire was used to establish expert recommendations by the members of the International Pediatric Otolaryngology Group, on the preoperative work-up, the perioperative considerations, and follow-up. RESULTS: Twenty-two members completed the survey, in 14 tertiary-care center departments representing 5 countries. The main consensual recommendations were: a precise otoscopic description of the quadrants involved, extensive audiological workup (bilateral tonal, vocal audiometry, and BERA), and a CT scan are required. Facial nerve monitoring and a combination of microscope and telescope are recommended for surgical removal. Clinical and audiological follow-up should be pursued yearly for at least 5 years. First MRI follow-up should be done at 18 months postoperatively if the removal violated the matrix. MRI follow-up duration depends on the initial extent of the cholesteatoma. CONCLUSION: The goal of preoperative and follow-up consensus from International Pediatric Otolaryngology Group participants is to help manage infants and children with congenital cholesteatoma. The operative techniques may vary, and experienced surgeons must perform these procedures.

International Pediatric Otolaryngology Group (IPOG) consensus recommendations: Management of suprastomal collapse in the pediatric population.

INTRODUCTION: Suprastomal Collapse (SuStCo) is a common complication of prolonged tracheostomy in children. There is a paucity of literature on this subject, especially regarding how to manage significant suprastomal collapse that prevents safe decannulation. OBJECTIVE: Provide a definition, classification system, and recommend management options for significant suprastomal collapse in children with tracheostomy. METHODS: Members of the International Pediatric Otolaryngology Group (IPOG) who are experts in pediatric airway conditions were surveyed and results were refined using a modified Delphi method. RESULTS: Consensus was defined as > 70% agreement on a subject. The experts achieved consensus: CONCLUSION: This consensus statement provides recommendations for medical specialists who manage infants and children with tracheostomies with significant Suprastomal Collapse. It provides a classification system to facilitate diagnosis and treatment options for this condition.

Adenotonsillectomy in the context of obstructive sleep apnoea.

Adenotonsillectomy (T&A) is a common surgical procedure. Its frequency is highest in the paediatric age range and its most common current indication is obstructive sleep apnoea (OSA). Sleep studies are used to document the presence and severity of OSA. This review will focus on indications for and complications of T&A in the context of the age range and setting where this surgery is undertaken for OSA in children.

Avoiding blindness in managing epistaxis for a child with Duane's Retraction Syndrome.

Duane's Retraction Syndrome (DRS), a congenital cranial dysinnervation disorder, accounts for 5% of all strabismus. A vascular anomaly in DRS, which became clinically relevant in the context of significant epistaxis, is presented. A 15-year-old girl with DRS underwent a rhinological procedure for traumatic nasal deformity and suffered large volume epistaxis. Using angiography, an anatomical variation was identified, noting the ophthalmic artery was supplied by branches from the sphenopalatine artery, facial artery, and middle meningeal artery; not from the internal carotid artery. Hence epistaxis control was achieved via alternative methods, and unilateral blindness was avoided.

Tertiary hospital retrospective observational audit of tonsillectomy.

OBJECTIVES: Tertiary hospitals see a wide array of complex paediatric patients requiring the procedure of tonsillectomy to alleviate airway symptoms. To investigate the implications of patient-specific factors on postoperative morbidities and hospital stay length, including the role of BMI and AH as predictors for airway complications following surgery. METHODS: A retrospective chart review was performed for all patients presenting at The Children's Hospital at Westmead for routine tonsillectomy between July 2010 and July 2014. RESULTS: Of 500 charts, 420 patients met inclusion criteria. 155 (37%) patients had a pre-existing comorbidity. Polysomnogram (PSG) was conducted prior to surgery (n = 129). BMI results showed a mean BMI of 20.0, n = 25 were overweight, n = 70 were obese and n = 11 underweight. 84 patients (20%) experienced a postoperative complication/unexpected morbidity. There were no returns to theatre and no mortality. 24 patients had more than one complication. Complication rate was highest in the patients <2 years of age. There was a statistically significant difference in the number of desaturation related complications between obese and non-obese groups p = 0.00480. There was statistically significant difference in length of hospital stay between the two groups. 16% of children with co-morbidities stayed for >2 nights in hospital (25/155) compared to 7.5% of children without co-morbidities p = 0.00607. 9% of children with co-morbidities stayed for 3 nights in hospital (14/155) compared to patients without co-morbidities (6/256), p = 0.00167. CONCLUSIONS: This audit confirms the impact of age, obesity and certain co-morbidities on the potential costs to the hospital in managing complications and length of stay after surgery.

International Pediatric Otolaryngology Group: Consensus guidelines on the diagnosis and management of type I laryngeal clefts.

INTRODUCTION: The diagnosis and management of type I laryngeal clefts can be controversial and varies across centers and surgeons. Using existing peer-reviewed literature to develop an expert-based consensus will help guide physicians in the treatment of these patients as well as develop research hypotheses to further study this condition. OBJECTIVE: To provide recommendations for the diagnosis and management of type I laryngeal clefts. METHODS: Determination of current expert- and literature-based recommendations, via a survey of the International Pediatric Otolaryngology Group, using a modified Delphi method. SETTING: Multinational, multi-institutional, tertiary pediatric hospitals. RESULTS: Consensus recommendations include diagnostic workup, medical management, pre-operative, intra-operative and post-operative considerations for type I laryngeal clefts. CONCLUSIONS: This guide on the diagnosis and management of patients with type I laryngeal clefts is aimed at improving patient care and promoting future hypothesis generation and research to validate the recommendations made here.
