Key points: Inhalational exposure (IE) history assessment is important and may guide chronic rhinosinusitis disease management.Combined exposure status was the most significant factor across differential gene expression analyseIE history was associated with pro‐inflammatory transcriptome changes and worse clinical outcomes.

This article presents a rare case of a large hairy polyp, a developmental malformation causing a benign tumor, within the nasopharynx. The patient, born with the polyp obstructing the airway, required immediate intubation and a combined transnasal‐transoral surgical approach for excision. The case underscores the challenges in diagnosing and managing such polyps, emphasizing the importance of imaging for surgical planning, and the consideration of multiple approaches to ensure complete resection and prevent recurrence.

Objective: Compare surgical and swallow outcomes in robotic versus traditional laryngeal cleft (LC) repairs. Study Design: Retrospective cohort study. Setting: Tertiary care pediatric hospital. Methods: Pediatric patients who underwent robotic or traditional (open or endoscopic) LC repair between 2010 and 2021 were identified. Patient characteristics, operative times, adverse events, hospital length of stay (LOS), and modified barium swallow study (MBSS) results were compared. Results: Eighteen robotic and thirty traditional LC repairs were identified. Mean surgical (149 vs 111 min, P <.05) and OR times (207 vs 139 min, P <.002) were increased for robotic type I LC repairs, but were similar for type II and III LC. Mean hospital LOS was increased for robotic type I LC repairs (2.6 vs 1.2 days, P <.006), but was decreased for type II (4 vs 12.2 days) and type III (4.3 vs 94.5 days) LC. Postoperative MBSS results were improved for robotic type I LC repairs at 12 months (82% vs 43%, P =.05), and trended toward improvement at 6 months for type II (75% vs 22%), and type III (67% vs 50%) LC repairs, although significance was limited for type II and III LC due to the number of subjects. A robotic approach was used successfully to revise all recurrent LC that failed traditional repairs. Conclusion: Robotic type 1 LC repairs demonstrated increased operative times and hospital LOS but improved postoperative swallow outcomes compared to traditional approaches may be particularly useful in cases of recurrent clefts.

Objective: While evidence continues to emerge on the negative health effects of electronic cigarettes (e‐cigarettes) on the lungs, little is known regarding their deleterious effects on the upper airway. The purpose of this review is to summarize the toxicological effects of e‐cigarettes, and their components, on the upper airway. Data Sources: PubMed, SCOPUS, EMBASE databases. Review Methods: Systematic searches were performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta‐analyses guidelines from 2003 to 2023. Studies were included if they investigated the toxicological effects of e‐cigarette exposure on human or animal upper airway tissue. Two authors independently screened, reviewed, and appraised all included articles. Results: A total of 822 unique articles were identified, of which 53 met inclusion criteria and spanned subsites including the oral cavity (22/53 studies), nasal cavity/nasopharynx (13/53), multiple sites (10/53), larynx (5/53), trachea (2/53), and oropharynx (1/53). The most commonly observed consequences of e‐cigarette use on the upper airway included: proinflammatory (15/53 studies), histological (13/53), cytotoxicity (11/53), genotoxicity (11/53), and procarcinogenic (6/53). E‐cigarette humectants independently induced toxicity at multiple upper airway subsites, however, effects were generally amplified when flavoring(s) and/or nicotine were added. Across almost all studies, exposure to cigarette smoke exhibited increased toxicity in the upper airway compared with exposure to e‐cigarette vapor. Conclusion: Current data suggest that while e‐cigarettes are generally less harmful than traditional cigarettes, they possess a distinct toxicological profile that is enhanced upon the addition of flavoring(s) and/or nicotine. Future investigations into underexamined subsites, such as the oropharynx and hypopharynx, are needed to comprehensively understand the effects of e‐cigarettes on the upper airway.

In this study, we compared 12 mm cell culture inserts with permeable polyester membranes (0.4 μm pores) from two different manufacturers: CELLTREAT® and Corning®. Physical dimensions and masses of the inserts were found to be very similar between the two brands, with CELLTREAT® inserts having a slightly smaller diameter and growth area (11.91 mm; 1.11 cm2) compared to Corning® Transwells® (12 mm; 1.13 cm2). We compared cell differentiation outcomes of human nasal epithelial cells (HNECs) at air–liquid interface grown on inserts from the two different manufacturers, including trans‐epithelial electrical resistance, ciliary beat frequency, ciliated area, and gene expression. HNECs from three male donors were used for all endpoints. No statistically significant differences were observed between paired cultures grown on different brands of insert. In conclusion, these inserts are comparable for use with airway epithelial cell model systems and likely do not impact cellular differentiation or cell culture quality. [ABSTRACT FROM AUTHOR]

Objectives/hypothesis: Optimizing value of medical service trips (MSTs) requires alignment of the services provided with the needs and desires of hosts. Our aim was to understand which MST services Vietnamese otolaryngologists find most beneficial and contrast to those believed most important by volunteers.Study Design: Cross-sectional survey.Methods: Otolaryngologists from a tertiary care institution travel to Vietnam yearly. In March 2018, surveys were distributed to Vietnamese otolaryngology faculty, residents, and US otolaryngology volunteers. The value of 11 MST-provided services were graded on a five-point Likert scale. Services included observing US otolaryngology volunteers perform surgery, US otolaryngology volunteer lectures, paper/electronic lecture material, instrument donation, minifellowships in the United States, among others. Respondents also voted for the single most important service. Responses were analyzed via Kruskal-Wallis analysis of variance and Wilcoxon rank sum test.Results: A total of 153 survey responses were recorded. There were 52% respondents who identified as male and 39% as female. The highest-valued services by Vietnamese otolaryngologists were didactic lectures given by US otolaryngology volunteers (4.6/5 ± 0.6), and reviewing cases with US otolaryngology volunteers in the clinic (4.4/5 ± 0.9). The least important services were instrument donation and seeing US otolaryngology volunteers assist with surgery (≤4.1/5). The highest-value services perceived by US otolaryngology volunteers were reviewing cases in the clinic and sponsoring minifellowships (4.9 ± 0.4). Vietnamese faculty perceived the single most important service to be US volunteer lectures (20/74 votes), whereas Vietnamese residents perceived minifellowships to be most important (13/34 votes) CONCLUSIONS: Vietnamese otolaryngologists desire an education-focused relationship with US otolaryngology volunteers, with didactic lectures and sponsored US fellowships having the highest value and performance of surgeries having less value.Level Of Evidence: 4 Laryngoscope, 130:E305-E310, 2020.
