Background: Current assessment techniques for determining whether a patient has normal interarytenoid anatomy, a deep interarytenoid notch, or a minor laryngeal cleft are highly variable. However, differentiating between these three entities is important, given it may distinguish whether a patient should be considered for surgical intervention. The Interarytenoid Assessment Protocol (IAAP) was developed to provide standardization of interarytenoid anatomy evaluations. We aimed to assess the reliability of the IAAP for assessment of interaytenoid mucosal height (IAMH) through a multi-institutional validation study., Methods: Reliability of the IAAP was assessed by 10 pediatric otolaryngologists all from different academic centers. 30 de-identified endoscopic videos of interarytenoid assessments were rated at two separate time points, 2 months apart. Intra-class correlation (ICC) coefficients with two-way models were used to evaluate inter- and intra-rater reliability., Results: Thirty endoscopic videos were collected for patients with a median (IQR) age of 4.9 years (59 months; range: 1 month to 20 years). On the first video assessment, inter-rater reliability was 0.74 (95% CI 0.63-0.84), and on the second video assessment, inter-rater reliability was 0.75 (95% CI 0.63-0.85) indicating strong inter-rater reliability. Overall intra-rater test-retest reliability was 0.75 (95% CI 0.69-0.79) indicating strong agreement. In almost half, 14 (46.6%) raters chose IAAP classification levels within 1 level of each other., Conclusions: Multi-institutional validation of the IAAP demonstrates strong inter- and intra-rater reliability for assessment of IAMH when evaluated through pictorial analysis. Standardization of anatomical evaluations may improve our ability to perform more reliable outcomes studies of pediatric pharyngeal dysphagia in the future., Level of Evidence: NA Laryngoscope, 2024., (© 2024 The American Laryngological, Rhinological and Otological Society, Inc.)

Objective: While management protocols of pediatric esophageal foreign bodies (EFBs) are well-delineated, resource utilization can be improved. This study's objectives were to explore hospital charges/costs for pediatric patients who present with EFBs and to identify patient risk factors associated with esophageal injury., Methods: A retrospective chart review of patients undergoing aerodigestive foreign body removal at a tertiary-care children's hospital from 2018 to 2021 was conducted. Data collected included demographics, medical history, presenting symptoms, EFB type, surgical findings, and hospital visit charges/costs., Results: 203 patients were included. 178 of 203 (87.7%) patients were admitted prior to operation. Unwitnessed EFB ingestion (p < 0.001, OR = 15.1, 95% CI = 5.88-38.6), experiencing symptoms for longer than a week (p < 0.001, OR = 11.4, 95% CI = 3.66-38.6) and the following presenting symptoms increased the odds of esophageal injury: dysphagia (p = 0.04, OR = 2.45, 95% CI = 1.02-5.85), respiratory distress (p = 0.005, OR = 15.5, 95% CI = 2.09-181), coughing (p < 0.001, OR = 10.1, 95% CI = 3.73-28.2), decreased oral intake (p = 0.001, OR = 6.60, 95% CI = 2.49-17.7), fever (p = 0.001, OR = 5.52, 95% CI = 1.46-19.6), and congestion (p = 0.001, OR = 8.15, 95% CI = 2.42-27.3). None of the 51 asymptomatic patients had esophageal injury. The median total charges during the encounter was $20,808 (interquartile range: $18,636-$24,252), with operating room (OR) (median: $5,396; 28.2%) and inpatient admission (median: $5,520; 26.0%) contributing the greatest percentage., Conclusions: Asymptomatic patients with EFBs did not experience esophageal injury. The OR and inpatient observation accounted for the greatest percentage of the hospital charges. These results support developing a potential algorithm to triage asymptomatic patients to be managed on a same-day outpatient basis to improve the value of care., Level of Evidence: 3 Laryngoscope, 134:4774-4782, 2024., (© 2024 The Authors.

Introduction: In patients undergoing patent ductus arteriosus (PDA) ligation there is a significant risk of left vocal fold paralysis (LVFP) particularly in premature neonates who are small for gestational age. The objective of this study is to determine the incidence of LVFP in infants following PDA ligation and report on long-term outcomes in patients with LVFP., Methods: We performed a prospective study of patients undergoing PDA ligation in the newborn intensive care unit (NICU) between April 2004 and May 2014. Following PDA ligation, flexible laryngoscopy was performed to assess vocal fold mobility. Patients were then followed longitudinally to determine long-term outcomes., Results: A total of 163 infants underwent PDA ligation. Thirty-six patients (22%) developed LVFP following the procedure. Twenty-five percent of neonates <1500 g experienced LVFP versus 5% of patients >1500 g (p = 0.033). Patients with LVFP were more likely to require a feeding tube (64% vs. 19.6%; p < 0.05) and spent more time in the NICU (135 days vs. 106 days; p < 0.05). Twenty-four patients received long-term follow-up. Six (25%) had complete resolution of LVFP, 10 (42%) were compensated, and 8 (33%) demonstrated persistent LVFP with no improvement., Conclusions: The incidence of LVFP after PDA ligation is high especially in extremely low birth weight children. The majority of patients recovered well with time, but further surgical intervention was required in uncompensated cases. Long-term follow-up of these patients is needed to ensure improvement.

Objective: (1) Review a multidisciplinary vascular anomalies center's practice regarding periprocedural anticoagulation for venous malformations (VM) and the associated risk of thromboembolic and disseminated intravascular coagulation (DIC) events. (2) Compare the risk of thromboembolic events and DIC post-procedure between head and neck (H&N) and extremity VM patients., Methods: An Institutional Review Board (IRB)-approved, retrospective chart review was performed on 120 VM patients. A thromboembolic event was defined as a thrombus formation post-sclerotherapy or post-surgery within 2 months in a distant or local venous structure not directly addressed by the procedure., Results: There were 39 cases involving the H&N and 81 cases based at the extremities. There were eight cases of post-procedure thrombus formation within the extremity VM group (8/71; 11.3%) as opposed to 0 cases in the H&N group (OR: 0, 95% CI .00-.09), p = .049. There was no difference in incidence of post-procedure thromboembolic events between those with elevated D-dimer (H&N: 0%, extremity: 22.7%, 5/22) and normal D-dimer values (H&N: 0%, extremity: 6.3% [1/16], P = .370). There was no difference in incidence of post-procedure thromboembolic events between those who received periprocedural anticoagulation (H&N: 0%, extremity: 21%, 4/19) and those who did not (H&N: 0%, extremity: 8.2%, 4/49), (Extremity: OR: 3.00, .67-13.50, P = .206)., Conclusion: Post-procedure thromboembolism is rare in the treatment of venous malformations, especially in the head and neck subsite. Regardless of anticoagulation use, there were no thromboembolic events for H&N VM patients. Such events are rare, and the odds may approach zero, especially with small sample size., Level of Evidence: 4 Laryngoscope, 131:1163-1167, 2021., (© 2020 American Laryngological, Rhinological and Otological Society Inc, "The Triological Society" and American Laryngological Association (ALA).)

Objectives: The clinical significance of the interarytenoid mucosal height (IAMH) in pediatric dysphagia, ranging from normal anatomy to a laryngeal cleft, is unknown. This study seeks to evaluate a cohort of patients who underwent evaluation of their IAMH during microdirect laryngoscopy (MDL) for associations between IAMH and dysphagia as diagnosed on preoperative videofluoroscopic swallow study (VFSS)., Methods: A retrospective case series of 1,351 patients who underwent MDL between 2011 and 2016 were reviewed for intraoperative evaluation of IAMH using our interarytenoid assessment protocol. After exclusions, 182 patients were divided into three groups: 1) thickened diet: VFSS with recommendation for thickened liquids (n = 82 of 182; 45.1%), 2) normal diet: VFSS with allowance of thin liquids (n = 19 of 182; 10.4%), and 3) control: no VFSS performed (n = 81 of 182; 44.5%)., Results: There was no difference in IAMH between groups (P = 0.35). Power analysis was able to achieve > 80% power to detect an effect size of ≥ 0.5 (1-5 mucosal height scale). The majority of patients in each group had an IAMH above the false vocal folds (thickened diet: 57.3%, normal diet: 57.9%, control: 64.2%). There were similar percentages of patients in each group with an IAMH at or below the true vocal folds (thickened diet: 4.9%, normal diet: 5.3%, control: 6.1%)., Conclusion: There was no significant association between IAMH and preoperative thickened liquid recommendation in this cohort. This data fails to support the hypothesis that the IAMH is an independent etiological factor for pediatric pharyngeal dysphagia. Further studies comparing IAMH with outcomes after feeding therapy and surgery may better clarify this relationship between anatomy and physiology., Level of Evidence: 4.

Fibrodysplasia ossificans progressiva (FOP) is a rare disorder that causes heterotopic bone formation leading to chest wall and spinal deformities. This case describes an 11-year-old female with FOP who presented in respiratory failure necessitating two emergent fiberoptic nasotracheal intubations. The patient had severe trismus, rotary flexion of the neck, and distortion of the airway. A three-dimensional printed model based off of a computed tomography reconstruction was created for an in situ simulation before the true procedure. The surgery and trach change were both uneventful. We propose that with careful preoperative planning, tracheotomy can be an appropriate option for FOP patients.

Objectives/hypothesis: Placement of tympanostomy tubes for recurrent or chronic otitis media is the most commonly performed ambulatory procedure in the United States. Etiologies have been speculated to be environmentally based, and studies have suggested a genetic component to the disease. However, no large-scale studies have attempted to define a familial component. The objective of this study was to determine the familial risk of otitis media requiring tympanostomy tubes (OMwTT) in a statewide population., Study Design: Retrospective observational cohort study with population-based matched controls., Methods: Using an extensive genealogical database linked to medical records, the familial risk of OMwTT was calculated for relatives of probands (46,249 patients diagnosed with OMwTT from 1996-2013) compared to random population controls matched 5:1 on sex and birth year from logistic regression models., Results: The median age at time of tympanostomy tube placement was 1 year (interquartile range, 0-2 years). First-degree relatives of patients with OMwTT, primarily siblings, had a 5-fold increased risk of OMwTT (P < 10 -16 ). Second-degree relatives were at a 1.5-fold increased risk (P < 10 -15 ). More extended relatives (third, fourth and fifth degree) showed a 1.4-fold increased risk (P < 10 -15 )., Conclusions: In the largest population-based study to date, a significant familial risk is confirmed in OMwTT, suggesting otitis media may have a significant genetic component given the increased risk found in close as well as distant relatives. This could be influenced by shared environments given a five-times risk observed in siblings. Further understanding the genetic basis of OMwTT and its interplay with environmental factors may clarify the etiology and lead to better detection of disease and treatments., Level of Evidence: 3b.

Objectives/hypothesis: To determine the relative risk of having eosinophilic esophagitis (EoE) coexist with chronic rhinosinusitis (CRS) in probands and their families using the Utah Population Database (UPDB)., Methods: This retrospective observational cohort study with population-based matched controls utilized the UPDB, a genealogical database linked to medical records. It was used to identify CRS and EoE patients diagnosed at any age between 2008 and 2012. The familial risks of an EoE diagnosis (International Classification of Diseases, Ninth Revision, Clinical Modification code 530.13) in CRS probands, and vice versa, and their first- through fifth-degree relatives and spouses were calculated using logistic regression models in comparison to controls randomly selected from the Utah population and individually matched 6:1 on sex and birth year., Results: Probands with CRS demonstrated a 3.4-fold increased risk of having EoE themselves (P < 10(-15) ). First-degree relatives (parents, siblings, and children) of CRS probands had a 1.5-fold increased risk of having EoE (P < 10(-4) ), whereas more distant relatives did not show a significant increased risk. Spouses of probands had a 1.4-fold increased risk of having EoE (P = 0.055). Conversely, risk estimates of having CRS in EoE probands were consistent., Conclusion: We observed an increased risk of comorbid EoE in patients with CRS and their families. An association between CRS and EoE as comorbid conditions suggests that a familial component is contributing to the etiology of both diseases. Further analyses regarding the pathophysiology of the development of CRS in these specific patients will lead to a better understanding of both disease processes and may help target therapy., Level of Evidence: 3b.
