RESUMEN

OBJECTIVES: The primary aim of this study is to describe a novel surgical technique developed for tongue base suspension (TBS). The second aim of this study is to assess the efficacy of the developed procedure by quantifying preoperative and postoperative polysomnographic outcomes for pediatric patients undergoing fluoroscopic-assisted tongue suspension (FATS) with the Encore System. Our hypothesis is that our FATS technique will provide at least a 50% reduction in the Apnea/Hypopnea Index (AHI), including in the medically complex pediatric population. STUDY DESIGN: Retrospective case series. METHODS: An electronic medical record review was conducted of patients who underwent FATS by a single surgeon at a tertiary care medical center between December 2019 and June 2022. Inclusion criteria included all patients <18 years old with evidence of OSA or sleep-disordered breathing and who had glossoptosis on sleep endoscopy. Data extracted from the medical record included age, gender, medical comorbidity history, reason for referral, history of airway surgeries, length of hospital stay, surgical complications data, and preoperative and postoperative polysomnographic data. Surgical success was defined by at least a 50% reduction in AHI. RESULTS: Thirty patients (53.3% male) with a mean age of 6.3 (±5.3, 0.16-17) years underwent FATS over the study period. Most patients (93%) had an underlying comorbidity: cerebral palsy (37%), chromosomal abnormalities (23%), Down syndrome (13%), Pierre-Robin sequence (10%), and obesity (10%). The majority of patients (77%) were explicitly referred for tracheostomy placement secondary to failed management of OSA. 21 patients completed both preoperative and postoperative polysomnograms. The mean preoperative AHI, obstructive AHI (oAHI), and respiratory disturbance index (RDI) were 28.8 (±19.8), 30.8 (±19.6), and 30.5 (±19.3), respectively. The mean postoperative AHI, oAHI, and RDI were 7.3 (±9.2), 7.5 (±9.1), and 7.9 (±9.3), respectively. The mean change in AHI was -21.5 (±21.4) events/h (p < 0.01, 95% CI -29.0 to -11.4 events/h). The mean percentage decrease in AHI was 74.7%. The mean change in oAHI and RDI were -23.3 (±21.9) events/h (p < 0.01 95% CI- 39.9 to -21.4 events/h) and -22.5 (±21.5) events/h (p < 0.01, 95% CI- 31.5 to -12.4 events/h), respectively. The mean percentage decrease in oAHI and RDI was 75.6% and 73.8%, respectively. Surgical success occurred in 16 of the 21 (76%) patients. Of the 23 patients referred explicitly for tracheostomy placement, 21 (91%) were able to avoid tracheostomy placement secondary to improvements in OSA. CONCLUSIONS: Patients undergoing fluoroscopic-assisted TBS revealed statistically significant improvements in AHI, oAHI, and RDI, with an overall surgical success rate of 76%. Complication rates were minimal, despite the complex nature of the study population. FATS should be considered a viable surgical approach in pediatric patients with an identified base of tongue obstruction and OSA. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:S1-S9, 2024.

RESUMEN

OBJECTIVE: Epiglottopexy has been an increasingly utilized intervention in children with epiglottic prolapse and airway obstruction. Given the role of the epiglottis in protecting the airway during swallowing and the potential effect of repositioning the epiglottis on the passage of the bolus, we aimed to compare swallowing outcomes before and after epiglottopexy in children. STUDY DESIGN: A retrospective cohort study. SETTING: Tertiary care children's hospital. METHODS: Data were extracted from charts of children who underwent epiglottopexy and had a subsequent instrumental swallowing evaluation between January 2018 and September 2022. RESULTS: A total of 93 patients underwent epiglottopexy. Of these, 38 patients met inclusion requirements. The mean age at surgery was 41 ± 47 months. Most patients (n = 37, 97.4%) had significant comorbidities such as secondary airway lesions (n = 33, 91.7%), a genetic or syndromic disorder (n = 25, 69.4%), and dysphagia (n = 29, 76.3%). All patients had a concurrent procedure at the time of epiglottopexy with supraglottoplasty (n = 24, 63.2%) and lingual tonsillectomy (n = 16, 42.1%) being the most common. No changes in initiation or patterns of swallowing were noted postoperatively. A total of 7 (18.4%) patients had worsening swallow function: 2 had new-onset dysphagia, and 5 had worsening pre-existing dysphagia. Liquid or food textures penetrated remained unchanged or improved in most cases. No risk factors for worsening dysphagia were identified in our cohort. CONCLUSION: Children with medical comorbidities undergoing epiglottopexy with additional airway interventions may experience new or worsening dysphagia. However, the procedure is generally safe without notable patterned changes in the swallowing mechanism.

RESUMEN

OBJECTIVE: To provide recommendations for a comprehensive management approach for infants and children presenting with symptoms or signs of aspiration. METHODS: Three rounds of surveys were sent to authors from 23 institutions worldwide. The threshold for the critical level of agreement among respondents was set at 80 %. To develop the definition of "intractable aspiration," each author was first asked to define the condition. Second, each author was asked to complete a 5-point Likert scale to specify the level of agreement with the definition derived in the first step. RESULTS: Recommendations by the authors regarding the clinical presentation, diagnostic considerations, and medical and surgical management options for aspiration in children. CONCLUSION: Approach to pediatric aspiration is best achieved by implementing a multidisciplinary approach with a comprehensive investigation strategy and different treatment options.

RESUMEN

OBJECTIVES: Examine the differences between traditional tower-based endoscopy (TBE) and smartphone-based endoscopy (SBE) using objective measures of cost, setup time, and image quality. METHODS: Cost analysis study and randomized single-blinded prospective trial was performed at a tertiary academic health center. Twenty-three healthcare providers, 2 PA-C, 9 residents, 2 fellows, 10 attendings varying in practice from 1 to 27 years were a part of the study. Actual cost analysis was used for purchase of the Karl Storz video tower system and the Save My Scope smartphone-based endoscopy system for cost analysis. For setup time, providers entered a room and were randomized to set up either an SBE or TBE system and timed from room entry to a visible on-screen image. A crossover was then performed so all providers performed both setups. For image discernment, standardized photos of a modified Snellen's test were sent via text message to providers who were blinded as to which photo represented which system. Practitioners were randomized as to which photo to receive first. RESULTS: Cost savings was 95.8% ($39,917 USD) per system. Setup time for the smartphone system was 46.7 seconds less than video tower system on average (61.5 vs 23.5 seconds; P < .001, 95% CI: 30.3-63.1 seconds). Level of visual discernment was slightly better for SBE over TBE, with reviewers able to identify Snellen test letters at a size of 4.2 mm with SBE versus 5.9 mm with TBE (P < .001). CONCLUSIONS: Smartphone-based endoscopy was found to be cheaper, quicker to set up, and to have marginally better image quality when transmitted via messaging than tower-based endoscopy, although the clinical significance of these visual differences are unknown. If appropriate for their needs, clinicians should consider smartphone-based endoscopy as a viable option for viewing and collaborating on endoscopic images from a fiberoptic endoscope.

RESUMEN

OBJECTIVE: To provide guidance for the comprehensive management of children referred for anterior drooling. The mission of the International Pediatric Otolaryngology Group (IPOG) is to develop expertise-based recommendations for the management of pediatric otolaryngologic disorders with the goal of improving patient care. METHODS: Survey of expert opinion by the members of the International Pediatric Otolaryngology Group (IPOG). The recommendations are derived from current expert consensus and critical review of the literature. RESULTS: Consensus recommendations include initial care and approach recommendations for health care providers who commonly evaluate children with drooling. This includes evaluation and treatment considerations for commonly debated issues in drooling management, initial work-up of children referred for anterior drooling, treatment recommendations, indications and contra-indications for rehabilitation, medical, and surgical management, as well as pros and cons of different surgical procedures in the hands of drooling management experts. CONCLUSION: Anterior drooling consensus recommendations are aimed at improving patient-centered care in children referred for sialorrhea.

RESUMEN

BACKGROUND: Severe laryngomalacia, characterized by apnea, hypoxia, and feeding difficulties, is an uncommon diagnosis that often requires surgical intervention with supraglottoplasty. Children who require surgery at a young age and those with additional comorbidities pose a special challenge and may require further surgical interventions. Posterior displacement of the epiglottis has been noted in some infants with congenital stridor and is commonly treated with epiglottopexy. The goal of our study is to review the outcomes of epiglottopexy combined with supraglottoplasty in our cohort of infants younger than 6 months old with severe laryngomalacia. METHODS: A retrospective chart review of infants younger than 6 months old who underwent epiglottopexy combined with supraglottoplasty for severe laryngomalacia from January 2018 to July 2021 at a tertiary care children's hospital. RESULTS: 13 patients (age 1.3 week-5.2 months) underwent supraglottoplasty and epiglottopexy for severe laryngomalacia and epiglottis retroflection. The patients were admitted to the intensive care unit and remained intubated for at least one night. All patients demonstrated subjective and objective improvement in upper airway respiratory signs and symptoms. Ten patients demonstrated aspiration immediately postoperatively, despite 4 of them having no concern for aspiration at preoperative evaluation. On follow-up, 1 patient required revision supraglottoplasty and epiglottopexy for persistent laryngomalacia, and 2 patients required tracheostomy tube placement due to cardiopulmonary comorbidities. CONCLUSION: Infants younger than 6 months old with medical comorbidities undergoing epiglottopexy with supraglottoplasty may demonstrate significant improvement in respiratory symptoms. Worsening dysphagia may complicate the postoperative period, particularly among children with medical comorbidities.

RESUMEN

BACKGROUND: Refractory obstructive sleep apnea (OSA) is a common condition in children with medical comorbidities, leading to a significant impact on quality of life. Drug-induced sleep endoscopy (DISE) has become the standard of care in identifying the levels of obstruction in children with refractory OSA. Epiglottopexy has been shown to improve OSA symptoms in adults and healthy children with epiglottic prolapse in a few studies, with minimal long-term complications. The objective of our study was to evaluate the role of epiglottopexy in children with refractory OSA. METHODS: A retrospective chart review of children with refractory OSA who were found to have epiglottic prolapse on DISE, and underwent epiglottopexy between January 2018 and November 2021 at a pediatric tertiary care hospital. RESULTS: 42 patients (age 8.1 ± 5.1 years) met inclusion criteria. Thirty patients (71.4 %) suffered from neurodevelopmental disease or congenital syndrome, and 14 patients (33.3 %) were gastrostomy-tube dependent. All patients had at least one prior surgical procedure to address their OSA. Thirty-six patients (85.7 %) were diagnosed with refractory OSA by polysomnography prior to surgery, with an average apnea-hypopnea index (AHI) of 12.4 ± 9.7/h. Forty patients (95.2 %) required an additional procedure in conjunction with epiglottopexy including lingual tonsillectomy (n = 27, 64.3 %), supraglottoplasty (n = 14, 33.3 %), tonsillectomy with or without revision adenoidectomy (n = 9, 21.4 %) and tongue base suspension (n = 1, 2.4 %). Twenty-one patients had repeated polysomnography; 4 patients were found to have residual severe OSA post-operatively (average AHI 17.4 ± 11.4/h), while the remaining patients demonstrated clinical improvement and a significant reduction in OSA severity, with an average AHI of 1.5 ± 2.2/h. Regression analysis identified pre-operative oxygen nadir <75 % to be associated with residual OSA postoperatively. Following surgery, 7 patients were found to have new-onset or worsening dysphagia, 6 of whom were diagnosed with complex medical comorbidities. CONCLUSIONS: Epiglottopexy, as part of multi-level airway surgery, is associated with a significant improvement in the severity of refractory OSA. Dysphagia may complicate the post-operative course, particularly in children with medical comorbidities.

RESUMEN

PURPOSE: This study was performed to investigate the effect of including immediate postoperative photographs of a tracheostomy site on diagnoses (correct and incorrect) of wound breakdown in a pediatric patient population. MATERIALS AND METHODS: Chart review was performed of all patients from 2017 to 2019 who underwent a tracheostomy. Within this time span, the practice of the hospital changed such that postoperative photography was taken of the tracheostomy site. There were no changes in in-service training protocols over this time. Wound breakdown diagnoses were examined prior to and after the intervention. Diagnoses were categorized by severity according to the National Pressure Ulcer Advisory Board. Diagnoses were then divided into correct or incorrect based on examination by physician teams at the time of the diagnosis. RESULTS: Forty five patients underwent a tracheostomy during the study period. When comparing the two groups, there was a reduction in all wound breakdown diagnosis by 91 %, and those diagnoses which were entered into the chart after the photos were verified as correct. CONCLUSIONS: Without appropriate context as to the nature of tracheostomy wounds, many providers may incorrectly grade a healthy wound as wound degradation, which can affect care, reimbursement, and hospital ratings. We present our findings of placing an intraoperative wound photo in the patient's electronic medical record as a reference should wound concerns arise. We believe this is an easy action which can enhance patient care, decrease unnecessary work, and provide an accurate documentation of tracheostomy care pathways and results.

RESUMEN

OBJECTIVES: Neurodevelopmentally impaired (NI) children with chronic sialorrhea are at elevated risk for aspiration and respiratory tract infections. Direct resection or ligation ("DROOL") of the submandibular glands (SMG) with parotid duct ligation are surgical interventions intended to decrease salivary output. The objective of this study is to determine the impact of DROOL surgery on the incidence of nonviral respiratory-related (NVR) post-procedure hospital encounters including emergency department visits and admissions. METHODS: Retrospective case series of NVR related outcomes after DROOL surgery in children performed at a single institution, tertiary referral center. RESULTS: A total of 35 gastrostomy tube-dependent patients (60% male, average age 8.2 [SD 6.0] years) with NI underwent DROOL surgery (86% SMG excision). Pre- and post-surgical follow-up time was 3.6 and 3.2 years, respectively. Presurgical and postsurgical NVR hospital encounters occurred in 28 (80%) and 14 (40%) patients, respectively (p < 0.01). Mean (SD) postoperative NVR hospital encounters occurred less frequently when compared to presurgical period (0.4 [0.6] vs. 1.0 [1.2] per year, p < 0.01) with average change of -0.7 encounters per year (SD 1.4, 95% CI -1.0 to -0.2). Patients with encounters within a year preceding DROOL (OR 4.9, p = 0.04, 95% CI 1.1-22.8), or those with at least 3 preoperative encounters (OR 8.0, p = 0.01, 95% CI 1.6-40.3) were significantly associated with a postsurgical NVR event. Fewer patients used anti-sialorrhea medication postoperatively compared to preoperatively (60% vs. 17%, p < 0.01). No patient developed surgical site complications requiring operative interventions. CONCLUSIONS: DROOL surgery for chronic sialorrhea in patients with NI was associated with decreased hospitalization and ED visits for NVR respiratory events post-procedurally. Sialorrhea may be an actionable source of recurrent respiratory illnesses requiring hospitalizations.

RESUMEN

OBJECTIVES: The traditional endoscopic techniques for surgical management of laryngeal clefts are carbon dioxide (CO2) laser or microlaryngeal instruments (cold steel). This study compares the functional efficacy and safety of coblation, or "cold" radiofrequency ablation, to traditional approaches for endoscopic laryngeal cleft repair. METHODS: Patients who underwent endoscopic laryngeal cleft repair with CO2 laser, cold steel, or coblator at two tertiary academic centers from 2015 to 2021 were retrospectively identified. The primary outcome studied was swallowing function: pre- and postoperative swallow studies were scored according to the International Dysphagia Diet Standardization Initiative with higher scores indicating worse swallow function. Secondary outcomes included surgical complications and rates of dehiscence. RESULTS: Of the 53 patients included, 14 underwent repair with CO2 laser, 23 with cold steel, and 16 with the coblator. Mean age at surgery was 2.2 ± 1.1 years for the laser group, 4.3 ± 4.0 years for cold steel, and 1.9 ± 1.4 years for the coblator group. In the laser group, 100% of clefts were type I; for the cold steel group, 82.6% of clefts were type I and 17.4% were type II; for the coblator group, 93.8% of clefts were type I and 6.3% were type II. Pre- and postoperative swallow study scores were 6.3 ± 2.8 and 4.3 ± 3.2, respectively, (p = 0.001) for the laser group, 6.9 ± 2.8 and 5.3 ± 3.1 (p = 0.071) for the cold steel group, and 7.5 ± 1.5 and 4.0 ± 2.9 (p < 0.001) for the coblator group. Mean change in swallow study scores were similar across the three groups (p = 0.212). No patients experienced postoperative dehiscence at the surgical site or complications; no revisions were required. CONCLUSIONS: Cleft repair with the novel coblation technique showed significant improvements in swallow study scores without any occurrences of postoperative dehiscence or revisions. Coblation is a safe and efficacious approach for laryngeal cleft repair.

RESUMEN

Tocilizumab is reported to reduce systemic inflammation in individuals with SLC29A3 spectrum disorder, but its effect on hearing loss has not been described. The authors present a boy toddler with a history of prematurity, dysphagia, hypersplenism, hyperpigmentation, short height and hearing loss who was referred to the immunology clinic. He initially presented shortly after birth with abnormal hearing screens followed by positive urine test for cytomegalovirus. However, the infection was determined to be postnatally acquired and hearing loss most likely from genetic causes given a family history of hearing loss and consanguinity. A pathogenic variant in SLC29A3 was found on whole-exome sequencing and given concern for SLC29A3 spectrum disorder, steroids were started. Following concerns for development of side effects with chronic steroid use, he was switched to interleukin 6 inhibitor therapy. The patient's inflammatory markers decreased on tocilizumab, and his sensorineural hearing loss was notable for improvement and stabilisation on therapy.

RESUMEN

BACKGROUND: The purpose of this study was to evaluate the efficacy of sleep endoscopy-directed simultaneous lingual tonsillectomy and epiglottopexy in patients with sleep disordered breathing (SDB), including polysomnography (PSG) and swallowing outcomes. METHODS: A retrospective review was performed of all patients undergoing simultaneous lingual tonsillectomy and epiglottopexy over the study period. PSG objective measures were recorded pre- and postoperatively, along with demographic data, comorbidities, and descriptive data of swallowing dysfunction in the postoperative setting. RESULTS: A total of 24 patients met inclusion criteria for consideration, with 13 having valid pre- and postoperative PSG data. Successful surgery was achieved in 84.6% of patients, with no difference based on presence of medical comorbidities including Trisomy 21. Median reduction in obstructive apnea-hypopnea index (oAHI) with the procedure was 69.9%. Four patients (16.7%) had postoperative concern for dysphagia, but all objective swallowing evaluations were normal and no dietary modifications were necessary. CONCLUSION: Combination lingual tonsillectomy and epiglottopexy in indicated patients has a high rate of success in this single-institutional study without new dysphagia in this population. These procedures are amenable to a combination surgery in appropriately selected patients determined by sleep state endoscopy in the setting of SDB evaluated with drug-induced sleep endoscopy.

RESUMEN

OBJECTIVE: Equipment necessary to perform pediatric microlaryngoscopy/bronchoscopy (MLB) varies considerably depending on the selected interventions. In procedures with equipment variability, surgical case length may be increased due to the need to procure items intraoperatively. We hypothesized that use of standardized huddle tools listing necessary equipment would be associated with a shortened case duration in MLB. METHODS: As part of a quality improvement initiative at our academic, tertiary care pediatric hospital, a standardized huddle sheet was created that listed options of equipment for MLB. Listed items included telescope/bronchoscope size, laryngoscope selection, interventional equipment, suspension, microscopes, and topical medications. The tool was completed by otolaryngology and shared with the circulating nurse at the beginning of the day so equipment needs could be anticipated. The tool was introduced to staff in November 2017 and to trainees in February 2018. To assess intervention impact, monthly median surgical case duration and room turnover time were retrospectively tracked using control chart analysis from March 2017 to June 2019. RESULTS: At baseline, the centerline case duration was 49 min. Two months following introduction of the huddle sheet to trainees, the centerline duration decreased to 43 min. This change was sustained throughout the period studied. No changes in room turnover time were observed during this period. CONCLUSIONS: Standardized huddle tool use prior to MLB was associated with a median decrease of 6 min of operating room time without a change in operating room turnover time. Use of similar tools in procedures with significant equipment variability may be beneficial.

RESUMEN

ABSTRACT: Surgical management of the airway in children with Pierre Robin Sequence (PRS) includes tongue lip adhesion and mandibular distraction. Herein, the authors report the first case of an alternative surgical approach, the tongue base suspension (TBS).A full-term 5-week-old male with PRS with difficulty managing his airway through noninvasive mechanisms. A polysomnogram revealed severe obstructive sleep apnea (OSA) despite support. Parents desired the least invasive surgical approach, and therefore TBS was offered. Child underwent TBS without complications and weaned from 15L high flow to room air over 48 hours. Post-procedure polysomnogram revealed complete resolution of OSA. The child was discharged home without any supplemental support.The standard of surgical care for children with PRS has been either tongue lip adhesion or mandibular distraction. While their success is well-established, no alternatives have been considered. The authors demonstrate TBS can provide a less invasive, equally viable, and improved alternative in children with PRS.

RESUMEN

Children requiring a tracheostomy to maintain airway patency or to facilitate long-term mechanical ventilatory support require comprehensive care and committed, trained, direct caregivers to manage their complex needs safely. These guidelines were developed from a comprehensive review of the literature to provide guidance for the selection of the type of tracheostomy tube (cuffed vs uncuffed), use of communication devices, implementation of daily care bundles, timing of first tracheostomy change, type of humidification used (active vs passive), timing of oral feedings, care coordination, and routine cleaning. Cuffed tracheostomy tubes should only be used for positive-pressure ventilation or to prevent aspiration. Manufacturer guidelines should be followed for cuff management and tracheostomy tube hygiene. Daily care bundles, skin care, and the use of moisture-wicking materials reduce device-associated complications. Tracheostomy tubes may be safely changed at postoperative day 3, and they should be changed with some regularity (at a minimum of every 1-2 weeks) as well as on an as-needed basis, such as when an obstruction within the lumen occurs. Care coordination can reduce length of hospital and ICU stay. Published evidence is insufficient to support recommendations for a specific device to humidify the inspired gas, the use of a communication device, or timing for the initiation of feedings.

RESUMEN

OBJECTIVES: To determine demographic and patient variables associated with nothing by mouth (NPO) violations prior to surgery in a tertiary care pediatric hospital. METHODS: A retrospective study of patients <18 years of age undergoing elective surgery at a tertiary care children's hospital from 1/1/16 to 4/30/19 who violated their NPO guidelines was performed. Variables associated with a higher rate of NPO violations were analyzed among the different surgical sub-specialties. Additional analyses were performed comparing those with NPO violations to the total group of patients undergoing surgery in the study period. RESULTS: Of the 42 495 children who underwent elective surgical procedures in the study period, 625 (1.5%) committed NPO violations. The median age for those committing a violation was 3 years, and the majority (n = 421, 67.4%) were between 0 and 6 years of age. Otolaryngology patients committing NPO violations had a longer time between scheduling surgery and operative date than other surgical services (P < .0001), but a similar time as the urology service. Otolaryngology patients had the highest number of NPO violations (n = 245, 39.2%) compared to the other surgical services, despite doing 32.4% of the total surgical cases (P < .001). Children from Spanish-speaking homes accounted for 137 (21.9%) NPO violations, despite accounting for only 11.2% of total surgeries performed. Patients with Medicaid insurance (n = 438, 63.0%) had a higher rate of NPO violations, despite making up 43.6% of total patients. CONCLUSIONS: NPO violations occurred in 1.5% of patients during the study period, particularly among the youngest age range of the children analyzed, and they were most prevalent in the otolaryngology patients. Spanish speaking families, and those with Medicaid insurance had higher rates of NPO violations despite making up a smaller percentage of those being operated on overall. This highlighted the need for improvement in communication of fasting guidelines to caregivers. LEVEL OF EVIDENCE: 3.

RESUMEN

OBJECTIVE: To identify an age at which initiation of whole nut into the pediatric diet could be considered safe, by evaluating the age distribution of children undergoing bronchoscopy with removal of nut or seed material from the airway. METHOD: A retrospective chart review over a ten-year period identifying children age 0-18 that have undergone bronchoscopy with retrieval of airway foreign bodies. A statistical analysis of demographic data was carried out to identify age distribution of aspiration events. RESULTS: Sixty-four cases of foreign body aspiration were identified, of which 43 (67%) were of organic origin, specifically nuts. A Fisher's exact test was carried out on the cumulative percentage of organic foreign body aspirations to identify the age distribution of nut aspiration events. A statistically significant decrease in organic foreign body aspirations occurred at approximately 36 months of age (p = 0.004). CONCLUSION: Foreign body aspiration is a leading cause of accidental injury or death in children. Nut and other small organic foreign bodies account for a significant portion of accidental aspiration events, however, no guidelines exist regarding appropriate age of whole nut introduction into the diet. Our study suggests that 90% of pediatric nut aspiration events occur under the age of 36 months. We suggest supervised introduction of whole nuts between the ages of 3 and 4 years. Official guidelines regarding this should be considered by professional pediatric societies. LEVEL OF EVIDENCE: 4.
