AbstractObjectiveCartilaginous tumors of the larynx are rare, representing less than 1% of all laryngeal tumors. Chondromas are benign mesenchymal tumors characterized by a slow‐paced growth, primarily originated in the cricoid cartilage, followed by the thyroid, arytenoid, and epiglottic cartilages. This scoping review aims to understand the extent of evidence on the epidemiology, clinical characteristics, morbidity, and recurrence of the laryngeal chondroma (LC).Data sourcesMEDLINE (Ovid), Embase (Elsevier), Web of Science (Clarivate), Cochrane Central Register of Controlled Trials and Systematic Reviews, Lilacs, Scopus, and Google Scholar databases.Review methodsThe scoping review was conducted from 1816 to 2023, for observational studies describing LC. Titles and abstracts were screened for relevance, followed by an evaluation of the full text for eligibility. The data were collected from the qualifying articles, and a narrative summary of the outcomes was prepared.ResultsOne hundred and nineteen studies met the inclusion criteria. Ninety‐four case reports, 22 case series, and 3 cohorts. Two hundred and four participants with a diagnosis of LC were described. Male:female ratio was 2.8:1. The most common localization was the cricoid (113; 47.08%), followed by the thyroid (45; 18.75%), and the arytenoid cartilage (27; 11.25%). Dyspnea (78.85%) and hoarseness (74.28%) were the most reported symptoms. The recurrence rate was 11.25%, and complications were uncommon following the resection.ConclusionThis scoping review found a low‐frequency rate over all the cartilaginous laryngeal tumors. Most patients were treated with resection, with a low rate of malignancy conversion. This population has low attributable mortality, morbidity, and recurrence according to the current literature.

Abstract Background: The three delays model, identifies three key stages to delays in care that can contribute to adverse outcomes: decision-making to seek care, accessing healthcare facilities, and receiving appropriate medical care. However, the application of this model in otolaryngology-head and neck surgery (OHNS) and in a human conflict environment has not been examined. This study aims to explore the impact of each delay type within the OHNS population in post-war Mekelle, Ethiopia. By investigating these delays, the study seeks to uncover strategies for reducing delays and improving outcomes in the management of OHNS pathology for this and similar environments. Methods: This study was conducted during a 3-week short term OHNS surgical trip in Mekele, Ethiopia, following a 2 year war. A total of 105 patients attending the OHNS clinic were identified and given verbal interviews and semi-structured questionnaires. The three delays model was applied to analyze the data collected, focusing on the following aspects: 1) decision to seek care, 2) reaching care, and 3) receiving care. Results: A total of 105 patients were included in the analysis, with 100% (105/105) experiencing type 1 delays (decision to seek care), 75% experiencing type 2 delays (75/105) and an additional 77% (77/105) facing type 3 delays (receiving appropriate care after reaching health care facility). More than half of the patients encountered delays in all three types. Various factors contributed to type 3 delays, including multiple delays at the time of admission, drug shortages, non-availability of skilled staff, and incompetence. Cost of transportation emerged as the primary factor contributing to type 2 delays. Conclusion: The findings provide valuable insights into the specific delays experienced by patients seeking OHNS services in a post-war setting and inform potential strategies for improving healthcare delivery in similar contexts.

Epstein-Barr virus (EBV) belongs to the group of human herpes virus and can cause clinical and subclinical infections. Although EBV-related disease presentations are similar, they can lead to oncogenic transformation with various clinical manifestations. A thorough workup with morphology, immunohistochemistry, and molecular studies is crucial for the diagnosis of EBV-positive polymorphic B-cell lymphoproliferative disorder, not otherwise specified (NOS), which is a new entity introduced by International Consensus Classification in 2022. We describe an interesting presentation of EBV-positive polymorphic B-cell lymphoproliferative disorder with laryngeal involvement to bring awareness to this entity and we would like to address the need for more accessible treatment options.

Abstract Importance: There is a notable lack of low-cost OHNS simulation models that are relevant for early medical trainees and students. By conducting this study, we will understand the current landscape of low-cost otolaryngology-head and neck surgery simulation for early medical trainees and students. Objectives: Medical simulation is essential for surgical training yet is often too expensive and inaccessible in low- and middle-income countries (LMICs). Furthermore, in otolaryngology-head and neck surgery (OHNS), while simulation training is often focused on senior residents and specialists, there is a critical need to target general practitioners who carry a significant load of OHNS care in countries with limited OHNS providers. This scoping review aims to describe affordable, effective OHNS simulation models for early-stage trainees and non-OHNS specialists in resource-limited settings and discuss gaps in the literature. Evidence Review: This scoping review followed the five stages of Arksey and O’Malley’s Scoping Review Methodology. Seven databases were used to search for articles. Included articles discussed physical models of the ear, nose, or throat described as “low-cost,” “cost-effective,” or defined as <$150 if explicitly stated; related to the management of common and emergent OHNS conditions; and geared towards undergraduate students, medical, dental, or nursing students, and/or early-level residents. Findings: Of the 1706 studies screened, 17 met the inclusion criteria. Most studies were conducted in HICs. Most models were low fidelity (less anatomically realistic) models. The most common simulated skills were peritonsillar abscess aspiration and cricothyrotomy. Information on cost was limited, and locally sourced materials were infrequently mentioned. Simulations were evaluated using questionnaires and direct observation. Conclusion and Relevance: Low-cost simulation models can be beneficial for early medical trainees and students in LMICs, addressing resource constraints and improving skill acquisition. However, there is a notable lack of contextually relevant, locally developed, and cost-effective models. This study summarizes existing low-cost OHNS simulation models for early-stage trainees and highlights the need for additional locally sourced models. Further research is needed to assess the effectiveness and sustainability of these models.

ObjectiveThe aim was to study laryngological complaints in patients with hypermobile Ehlers‐Danlos syndrome (hEDS) or hypermobility spectrum disorders (HSD).MethodsA total of 363 patients met inclusion for the study by completing questions related to voice, upper airway, and swallowing between July 7, 2020 and July 13, 2022. Demographic data, voice‐related questions, and hypermobility diagnosis were analyzed retrospectively. From those, 289 patients were diagnosed with hEDS or HSD with 74 that did not meet the diagnostic criteria for either diagnosis serving as controls.ResultsThere were no statistically significant differences between patients with hEDS and HSD regarding Voice Handicap Index (VHI‐10) scores, voice, upper airway, or swallow complaints. However, more hEDS/HSD patients answered positively to the laryngeal dysfunction question versus controls (p = 0.031). 22.5% of hEDS/HSD patients (n = 65) reported hoarseness, of which 52.3% reported hoarseness >2 days/month. 33.9% (n = 98) with hEDS/HSD reported symptoms of dysphagia, and 27.0% (n = 78) reported laryngeal dysfunction symptoms. Controls demonstrated 20.3% prevalence of hoarseness, of which 46.7% reported hoarseness >2 days/month. 24.3% of controls had dysphagia and 14.9% laryngeal dysfunction symptoms. Of the 363 patients, VHI‐10 scores >11 were more likely in patients reporting >2 days of hoarseness/month (p = 0.001) versus those with <2 days of hoarseness/month. There was an increased prevalence of voice, upper airway, and dysphagia symptoms in hEDS/HSD patients compared with previously reported prevalence data in the general population.ConclusionA significant proportion of patients diagnosed with hypermobility due to hEDS or HSD were found to have voice, upper airway, and dysphagia symptoms. These rates are higher than those previously reported in the general population.Level of Evidence3 Laryngoscope, 134:773–778, 2024

Objectives Transplant patients are high risk for surgery due to their immunocompromised state. There is a paucity of evidence concerning the differences in incidence of chronic rhinosinusitis (CRS) in solid versus non-solid organ transplant. Our aim is to analyze the difference in incidence of CRS requiring endoscopic sinus surgery (ESS) between non-solid and solid transplant populations and determine if certain risk factors are associated with increased incidence of recalcitrant CRS in non-solid versus solid transplants. Study Design Retrospective cohort. Setting Multisite tertiary academic center. Methods This is a retrospective chart review of 1303 transplant recipients who were seen in our rhinologic clinic for CRS between 2017 and 2022. A total of 224 patients underwent ESS and were further analyzed for risk factors associated with recalcitrant disease requiring sinus surgery. Subgroup analysis based on solid and non-solid organ transplant was performed. Results Of the 224 patients in the study, 171/224 (76.3%) had solid transplants while 53/224 (23.6%) had non-solid transplants. 17.19% of all transplant recipients required ESS. The incidence of ESS in non-solid transplants was 28.2% versus 57% in solid transplant. The risk of recalcitrant CRS in solid transplant recipients was almost 1.78 times greater than those with non-solid organ transplant (95% CI, 1.27-2.54, p = 0.0005). Individual factors such as certain immunotherapy drugs, pancytopenia, and rejection appear to correlate with the risk of ESS in both non-solid and solid organ transplant. Conclusion Risk of ESS was greater in the solid transplant recipients compared to those who received non-solid organ transplant.

AbstractObjectivePrevious studies have suggested that patients with aspirin‐exacerbated respiratory disease (AERD) have a high likelihood of alcohol intolerance. The purpose of this systematic review is to identify if there is sufficient evidence to confirm this correlation and the impact of medical therapy on subsequent alcohol tolerance.Data SourcesPubMed, EMBASE, SCOPUS, EBSCO, Google Scholar, Cochrane Library, and Grey literature. We also performed snowballing on the identified observational studies (OS) for additional data.Review MethodsA systematic review was conducted from 1968 to 2022 to identify those studies describing AERD symptomatology triggered by alcohol intake. The primary outcome was to analyze the current literature for the association between alcohol intolerance and AERD symptoms. The secondary outcome looked for improvement in alcohol tolerance after aspirin desensitization or biological therapy.ResultsA total of 775 studies were identified and 40 abstracts were evaluated. From these, 5 studies met the inclusion criteria. Of the 5 manuscripts, there was 1 case‐control, 2 cohort, and 2 cross‐sectional studies. A total of 522 participants with AERD and a history of alcohol consumption were included, with 52.8% reporting at least 1 sinopulmonary exacerbation after alcohol intake. One of 3 studies noted improvement in alcohol tolerance after medical therapy with aspirin desensitization.ConclusionThe current literature suggests that patients with AERD have a high risk of alcohol intolerance. Additionally, aspirin desensitization may improve alcohol tolerance in this patient population.

AbstractObjectiveStudies suggest that transplant patients are at risk for chronic rhinosinusitis (CRS). However, there is limited information in the literature regarding frequency and reasons for failure of adequate medical therapy. We aim to determine the risk factors associated with the development of medically recalcitrant CRS requiring endoscopic sinus surgery (ESS).Study DesignRetrospective cohort.SettingMayo Clinic.MethodsThis is a retrospective chart review of 925 transplant recipients seen at Mayo Clinic between 2017 and 2022. Inclusion criteria: (1) a rhinologic consultation after transplant and (2) clinical diagnosis of CRS. A total of 549 patients met the inclusion criteria and were divided based on the need for ESS versus successful treatment with medical therapy. Univariate and logistic regression analyses were performed to identify risk factors and predictive variables related to failure of medical therapy.ResultsOf the 549 patients, 201/549 (37%) had medically recalcitrant disease requiring ESS, while 348/549 (63%) were successfully treated with medical therapy Based on logistic regression, patients with recurrent acute rhinosinusitis in the pretransplant period were 8.68 more likely to have a recalcitrant disease (95% confidence interval, 3.72‐20.28, p < 0.0001). Some of the largest determinants of medical therapy failure in the posttransplant period were CRS with nasal polyps, odontogenic CRS, and noninvasive fungal sinusitis. The presence of neutropenia, aplastic anemia, and living transplant were also associated with medically recalcitrant CRS requiring ESS.ConclusionOur predictive model identifies with high accuracy the patients who may be at risk of developing recalcitrant CRS in the organ transplant population.
