Background

Eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP) is associated with severe symptoms and poor outcomes, but the diagnostic criteria remain elusive. The objective of this study is to identify preoperative predictors of ECRSwNP using multiple diagnostic thresholds and to propose a clinically actionable risk stratification model.

Methods

A retrospective analysis was conducted on 1081 CRSwNP patients who underwent endoscopic sinus surgery. Receiver operating characteristic (ROC) curves were generated to predict ECRSwNP based on clinical features and identify reliable predictors.

Results

Both the blood eosinophil count and ratio were identified as indicators for predicting ECRSwNP. The ratio exhibited the strongest correlation with that of tissue (r = 0.401, p < 0.001). The optimal blood eosinophil ratio cutoffs exhibited variability according to tissue-based criteria, ranging from 2.65% to 4.65%. For blood eosinophil ratios, thresholds of 2.65% (for > 10% tissue ratio) and 3.85% (for > 27% tissue ratio) exhibited divergent predictive profiles: the former yielded high positive predictive value (PPV = 79.87%), while the latter yielded high negative predictive value (NPV = 84.39%). To reconcile conflicting PPV/NPV profiles between thresholds, we defined a threshold of 3.25% (median between 2.65% and 3.85%). Patients could be divided into a group with a low risk(LR-ECRSwNP) for being defined as ECRSwNP and another group with a high risk(HR-ECRSwNP), of which the median values with interquartile ranges (IQRs) were 15.20 (2.20, 31.50)/HPF and 12.06 (1.84, 21.77)% tissue eosinophils for the low risk group and 30.67 (16.53, 77.90)/HPF and 23.92 (14.09, 45.66)% tissue eosinophils for the high risk group. The HR-ECRSwNP demonstrated significantly higher tissue eosinophil counts and ratios than the LR-ECRSwNP (p < 0.001).

Conclusion

Blood eosinophil ratio ≥ 3.25% identifies CRSwNP patients at high risk for eosinophilic inflammation, providing a preoperative stratification tool. While correlations between blood and tissue eosinophils were moderate, this threshold balances sensitivity and specificity across heterogeneous diagnostic criteria.

背景嗜酸性慢性鼻窦炎伴鼻息肉（ECRSwNP）与严重症状和不良预后相关，但诊断标准尚不明确。本研究的目的是通过多个诊断阈值确定ECRSwNP的术前预测因素，并提出临床可操作的风险分层模型。方法对1081例行鼻内镜手术的CRSwNP患者进行回顾性分析。生成受试者工作特征（ROC）曲线，根据临床特征预测ECRSwNP并确定可靠的预测因子。结果血嗜酸性粒细胞计数和比值均可作为预测ECRSwNP的指标。该比值与组织的相关性最强（r = 0.401, p < 0.001）。根据组织标准，最佳血嗜酸性粒细胞比例临界值在2.65%至4.65%之间存在差异。对于血嗜酸性粒细胞比率，2.65%（组织比例为10%）和3.85%（组织比例为27%）的阈值具有不同的预测特征：前者具有较高的阳性预测值（PPV = 79.87%），而后者具有较高的阴性预测值（NPV = 84.39%）。为了调和阈值之间相互冲突的PPV/NPV分布，我们将阈值定义为3.25%（中位数为2.65%至3.85%）。将患者分为低危组（LR-ECRSwNP）和高危组（HR-ECRSwNP），其中低危组组织嗜酸性粒细胞中位数（IQRs）为15.20 (2.20,31.50)/HPF和12.06(1.84,21.77)%，高危组组织嗜酸性粒细胞中位数为30.67 (16.53,77.90)/HPF和23.92(14.09,45.66)%。HR-ECRSwNP的组织嗜酸性粒细胞计数和比值明显高于LR-ECRSwNP （p < 0.001）。结论血嗜酸性粒细胞比值≥3.25%的CRSwNP患者存在嗜酸性粒细胞性炎症的高风险，可作为术前分层的工具。虽然血液和组织嗜酸性粒细胞之间的相关性是中等的，但这个阈值平衡了不同诊断标准的敏感性和特异性。

Objective

Preserving the recurrent laryngeal nerve (RLN) is a critical aspect of thyroidectomy, as its injury can significantly impair voice function. However, surgeons frequently encounter branched RLNs, which occur in 10.1%–42.9% of cases. This anatomical variation can be particularly challenging for novice surgeons, as identifying and preserving the motor branch requires precision.

Methods

Of 239 patients who received bilateral axillo-breast approach robotic total thyroidectomy from December 2023 to January 2025, patients with extralaryngeal RLN branch were retrospectively evaluated using video recordings. The function of RLN branches was determined using intraoperative neuromonitoring (IONM). Branch diameter and branching distance to the laryngeal entry point (LEP) were measured on captured surgical images using ImageJ software, referencing a 1.3 mm monopolar hook tip. Sensory branches were further classified by insertion site (LEP vs. non-LEP).

Results

Among 293 RLNs at risk, 31 (10.6%) showed extralaryngeal branching. Most nerves were double-branched (27/31). Motor branches were significantly thicker than sensory branches (1.47 ± 0.34 mm vs. 1.02 ± 0.28 mm, p < 0.001). Of 34 sensory branches, 13 inserted into the LEP and 21 into non-laryngeal structures. LEP-inserting sensory branches were thicker (1.19 ± 0.22 mm vs. 0.93 ± 0.22 mm, p = 0.01) and branched closer to the LEP (17.77 ± 6.15 mm vs. 26.44 ± 7.71 mm, p = 0.001).

Conclusion

Branch diameter correlates with motor function in RLN branches. In the absence of IONM, thickness and branching location may help surgeons distinguish motor from sensory branches and preserve vocal function.

目的保护喉返神经是甲状腺切除术的重要内容，喉返神经损伤会严重损害声带功能。然而，外科医生经常遇到分支性rln，发生率为10.1%-42.9%。这种解剖变异对外科新手来说尤其具有挑战性，因为识别和保存运动分支需要精度。方法对2023年12月至2025年1月行双侧腋窝-乳房入路机器人甲状腺全切除术的239例患者进行录像回顾性评价。术中神经监测（IONM）测定RLN分支功能。参考1.3 mm单极钩尖，使用ImageJ软件测量手术图像上的分支直径和到喉入口点（LEP）的分支距离。感觉分支按插入部位进一步分类（LEP与非LEP）。结果293例危险RLNs中，31例（10.6%）出现咽外分支。大多数神经为双支（27/31）。运动分支明显厚于感觉分支（1.47±0.34 mm比1.02±0.28 mm, p < 0.001）。在34个感觉分支中，有13个进入喉外结构，21个进入喉外结构。插入LEP的感觉分支较粗（1.19±0.22 mm比0.93±0.22 mm, p = 0.01），分支更靠近LEP（17.77±6.15 mm比26.44±7.71 mm, p = 0.001）。结论RLN分支直径与运动功能相关。在缺乏IONM的情况下，厚度和分支位置可以帮助外科医生区分运动分支和感觉分支，并保持声带功能。证据等级4级。

Objectives

To review septal perforation management and outcomes in patients with hereditary hemorrhagic telangiectasia (HHT).

Methods

Collection and presentation of patient demographic, perforation size, and prior perforation and HHT treatment data over a 20-year period. Symptom and quality of life treatment outcomes were determined using the Nasal Obstruction Symptom Evaluation (NOSE)-Perf scale and the 5-Factor Glasgow Inventory (GBI-5F), respectively, in patients treated since 2017.

Results

Nine patients met study criteria. Mean (range) age was 64.4 (52–80) years and seven were biological males. Mean (range) perforation length and height were 1.9 (1.2–2.6) and 1.4 (1.0–1.8) cm. Four patients were treated with a customized septal button, one with posterior septal resection, and four with endonasal bilateral mucosal flap repair supported with an interposition graft. The button prostheses were well tolerated and the surgical closures successful at 8–60 months postoperatively. Subjective responses in the first three patients, and NOSE-Perf with GBI-5F scores in the latter six patients, demonstrated symptom and quality of life improvement for all patients. Perforation repair patients demonstrated substantial improvement in mean GBI-5F subdomain scores for quality of life, self-confidence, and social involvement and all have undergone sodium tetradecyl sclerotherapy injection postoperatively without re-perforation.

Conclusion

Symptom and quality of life improvement can be achieved in HHT patients with a perforation using customized septal buttons, posterior septal resection, or bilateral flap surgical repair. Surgical closure combined with injection sclerotherapy is feasible with a low risk of re-perforation and represents an effective treatment strategy in selected patients.

Objective(s)

To determine the association between parent-reported problem behaviors and objectively measured response inhibition in children with sleep-disordered breathing (SDB). Understanding this concordance could facilitate better clinical decision-making, as parent reports often guide treatment decisions despite unclear relationships with objective behavioral measures.

Methods

This prospective observational study was conducted at a tertiary care pediatric otolaryngology clinic from 1/1/24–12/1/2024. Children aged 5–11 years with SDB symptoms were included, while those with clinically significant psychiatric or neurologic disorders were excluded. Parent-reported problem behaviors were measured using the Behavior Rating Inventory of Executive Function (BRIEF), with the inhibit T-score as the primary predictor. The primary outcome was performance on the Flanker Test of Inhibitory Control and Attention, which measures response suppression to irrelevant stimuli while maintaining attention to target stimuli. Relationships between BRIEF scores and Flanker Test performance were assessed using Pearson correlation and linear regression, adjusting for sociodemographic factors.

Results

Among 84 participants (mean age: 93 months [95% CI, 89–98], 56% male), parent-reported inhibitory problems showed a small but statistically significant correlation with response inhibition performance (r = −0.23, p = 0.04) in unadjusted analyses. This relationship was attenuated after adjusting for demographic and socioeconomic factors. Other behavioral domains showed weaker associations. Adjusted R² values ranged 0.14–0.16, indicating parent reports explained minimal variance in objective scores.

Conclusion

Parent-reported behavioral problems showed limited concordance with objective measures of response inhibition in children with SDB. Treatment decisions for pediatric SDB should not rely solely on parent-reported behavioral symptoms, highlighting the need for integrating objective assessments when feasible.

目的：探讨睡眠呼吸障碍（SDB）患儿家长报告的问题行为与客观测量的反应抑制的关系。理解这种一致性可以促进更好的临床决策，因为尽管与客观行为测量的关系不明确，但家长报告经常指导治疗决策。方法：本前瞻性观察研究于2024年1月1日至12月1日在某三级儿科耳鼻喉科门诊进行。纳入5-11岁伴有SDB症状的儿童，排除有临床显著精神或神经障碍的儿童。使用执行功能行为评定量表（BRIEF）测量父母报告的问题行为，抑制t分数作为主要预测因子。主要结果是抑制控制和注意的Flanker测试的表现，该测试测量对无关刺激的反应抑制，同时保持对目标刺激的注意。BRIEF分数与Flanker测试成绩之间的关系采用Pearson相关和线性回归进行评估，并对社会人口因素进行调整。结果：在84名参与者中（平均年龄：93个月[95% CI， 89-98]， 56%为男性），未经调整的分析中，父母报告的抑制问题与反应抑制表现有很小但有统计学意义的相关性（r = -0.23, p = 0.04）。在调整了人口和社会经济因素后，这种关系减弱了。其他行为领域表现出较弱的关联。调整后的r2值为0.14-0.16，表明家长报告解释了客观评分的最小方差。结论：父母报告的行为问题与SDB患儿反应抑制的客观测量结果的一致性有限。儿科SDB的治疗决策不应仅仅依赖于父母报告的行为症状，强调在可行的情况下需要整合客观评估。证据等级：3。

Objective

This study aimed to evaluate the clinical remission rate and changes in medication use in patients with eosinophilic chronic rhinosinusitis (ECRS) treated with dupilumab for > 2 years.

Methods

This retrospective study included 19 patients with ECRS who received dupilumab therapy for > 2 years. The nasal polyp, Lund–Mackay on sinus CT, and SNOT-22 scores were assessed at baseline, 3 months, 1 year, and at the final evaluation. Remission was defined as sustained fulfillment of specific clinical and endoscopic criteria for at least 12 months. The use of concomitant medications was also assessed.

Results

Polyp score significantly improved from 6.1 ± 0.6 at baseline to 0.68 ± 1.2 at final evaluation. SNOT-22 scores decreased from 42.8 ± 20.0 to 14.1 ± 10.2. Clinical remission was achieved in 15 patients (79%). The remaining four patients did not meet the remission criteria because of persistent olfactory dysfunction or nasal obstruction. Significant reductions in the use of oral corticosteroids, drop-type intranasal corticosteroids, nasal spray corticosteroids, leukotriene receptor antagonists, and inhaled corticosteroids were also observed.

Conclusion

Dupilumab therapy for > 2 years resulted in a high clinical remission rate and reduced the need for concomitant medications in patients with ECRS. Persistent olfactory dysfunction is the main reason for non-remission, indicating the need for further therapeutic strategies in such refractory cases.

Objective

Consumer interest in ear hygiene has created an industry worth $2 billion, offering tools claiming to assist in cerumen removal. In this study, we aimed to compare the efficacy of self-operated over-the-counter (OTC) cerumen removal devices.

Methods

A community-based, prospective randomized trial was conducted at the Driven to Discover Research Facility at the Minnesota State Fair. A total of 529 adults aged ≥ 18 years were prospectively recruited; 149 met inclusion criteria for randomization to one of four OTC cerumen removal devices (cotton swab control, irrigator, powered and non-powered spiral tools). Cerumen burden and complications were evaluated via video-otoscopy by otolaryngologists before and after self-use of the assigned device using an objective grading system. Surveys on cerumen removal practices and consumer attitudes were completed. Group sociodemographic, survey, and cerumen burden data were compared between groups.

Results

Of 147 randomized trial participants with moderate to excessive cerumen in at least one ear (mean age 49 years, 48% female), 130 (88%) showed no improvement or worsening of cerumen burden grade following device use. There was no significant difference in the efficacy of the four OTC cerumen removal device groups. Observed complications included medial displacement of cerumen (17%), pain or discomfort (n = 7, 5%) and canal trauma (1%). While some participants would consider purchasing (29%) or recommending the device they used to others (27%), their preferred price point ($10–$20) was lower than the market price for all devices except cotton swabs.

Conclusion

Commonly used OTC cerumen removal devices did not result in a meaningful reduction of cerumen burden when used by the public and did not show superiority to cotton swabs. While it is unknown if device efficacy would improve with repeated use and familiarization, these findings do not currently support routine use of OTC cerumen removal devices for removal of excess cerumen.

Objective

Epistaxis can occur in individuals on anticoagulants, raising concerns about the potential impact on healthcare utilization. This retrospective analysis aims to compare measures of healthcare utilization of two cohorts: adult epistaxis patients without anticoagulant use compared to adult epistaxis patients on anticoagulants.

Methods

A retrospective analysis using TriNetX datasets from 2014 to 2024 compared the outcomes of two cohorts: cohort 1 (18,550 patients) named “Epistaxis without Anticoagulation > 18 years” and cohort 2 (9530 patients) named “Epistaxis with Anticoagulation > 18 years”. The populations were matched for demographics, leaving 5480 in each cohort. The following outcomes were measured: subsequent hospital care, Emergency Department (ED) services, hospital observation services, diagnostic radiology procedures of the chest, surgical procedures on the respiratory system, surgical procedures on accessory sinuses, and post-op control of nasal hemorrhage posterior or anterior.

Results

Analyses show Cohort 2 at an increased risk for subsequent hospital care (RR 5.99 [4.31–8.33]), ED services (RR 2.70 [2.39–3.03]), hospital observation services (RR 3.00 [1.81–4.98]), and diagnostic radiology procedures of the chest (RR 3.92 [3.25–4.74]). There was a significant increase in the number of ED services required by cohort 2 (p = 0.019). Cohort 1 was more likely to need control of anterior nasal hemorrhage using simple (p < 0.001) and complex (p < 0.001) methods.

Conclusion

This analysis highlights the potential impact of anticoagulation therapy on healthcare utilization in the management of epistaxis and underscores the importance of careful monitoring and appropriate management strategies for this patient population.

Objective

To evaluate the accuracy of artificial intelligence (AI) in establishing clinical decision-making in the treatment of advanced laryngeal cancer.

Methods

A structured question was elaborated for each of the seven recommendations chosen. Each Large Language Model (LLM) platform answered the questions. The Claude platform identified the differences between the guidelines and the responses generated and three specialists evaluated the impact of such differences.

Results

Of the 28 analyzed responses, 22 (78.6%) demonstrated content similarity with existing guidelines. Two responses showed that guidelines contained significantly more comprehensive content, three responses from LLMs provided additional content not demonstrated in the guidelines, and one response showed direct disagreement with established guidelines.

Conclusion

There was a 78.6% overlap in responses between guideline recommendations and LLMs. Therefore, while AI holds promise for transforming guideline creation, its integration into clinical practice must be carefully evaluated to ensure that it complements, rather than replaces, established expert-driven protocols.

Background

This study aimed to evaluate the feasibility of using superficial temporal vessels as recipient vessels for vascularized free flap reconstruction in “frozen neck” patients following radiotherapy for head and neck cancer (HNC).

Methods

Between February 2022 and November 2024, 16 patients underwent vascularized free flap reconstruction by using superficial temporal vessels at Peking University School and Hospital of Stomatology. Among them, anterolateral thigh flap (ALT, n = 5), radial forearm free flap (RFFF, n = 1), deep circumflex iliac artery microvascular free flap (DCIA, n = 8), and superficial iliac circumflex artery perforator flap (SCIP, n = 2) were utilized. Intraoperative vessel identification, flap survival, and postoperative complications were assessed.

Results

All patients attained optimal surgical outcomes. During the mean follow-up period of 9 months, all flaps survived with absence of major procedure-related morbidity.

Conclusion

Superficial temporal vessels offer a safe, reliable approach for vascularized free flap reconstruction in challenging “frozen neck” cases, providing an effective alternative in oral-maxillofacial reconstruction.

Objective

To investigate the impact of balance and dizziness problems (BDP) and other risk factors on falls in a longitudinal, population-based cohort of older adults.

Methods

The Age, Gene/Environment Susceptibility-Reykjavik Study (AGES-RS I) 2002–2006 examined 5764 adults aged 66–98. Five years later, 3316 surviving subjects were reexamined in AGES-RS II. Participants were asked about BDP, falls, usual activities, and health conditions. BDP symptoms during the past 12 months included: vertigo (spinning/moving sensation); floating/spacey sensation; light-headedness (no moving sensation); near fainting (presyncope) or fainting (syncope); blurred vision with head movement (oscillopsia); and feeling off-balance/unsteady. Clinical assessments included hand grip and leg strength plus steps and time to walk 6 m.

Results

During the past 12 months in AGES-RS II, BDP prevalence was 40.1% (males 35.2%, females 43.7%) and the prevalence of falling was 23.0% (males 20.9%, females 24.8%). BDP increased steps and time to walk 6 m. BDP increased the risk of falls (adjusted prevalence ratio [PR] = 1.53; 95% confidence interval [CI]: 1.34–1.76 for AGES-RS I, PR = 1.77, 95% CI: 1.55–2.03 for AGES-RS II). The prevalence of ≥ 2 falls was 8.9% (15.6% with BDP vs. 4.4% without BDP). Among those who fell ≥ 2 times, 70.4% reported BDP in the past 12 months. Additional risk of falling was associated with fear/panic attacks, memory loss, hearing loss, and other health conditions.

Conclusion

BDP are common in older adults and associated with 50% to 80% increased risk of falling and even greater risk of falling ≥ 2 times. Quantitative estimates are provided for contributing factors that further increase the risk of falls.

目的：探讨平衡和头晕问题（BDP）和其他危险因素对老年人跌倒的影响。方法：年龄，基因/环境易感性-雷克雅未克研究（ags - rs I） 2002-2006对5764名年龄在66-98岁之间的成年人进行了调查。5年后，3316名幸存的受试者在AGES-RS II中重新接受检查。参与者被问及BDP、跌倒、日常活动和健康状况。过去12个月BDP症状包括：眩晕（旋转/移动感觉）；浮动/史派西的感觉;头晕（没有移动感觉）；接近晕厥（晕厥前期）或晕厥（晕厥）；视力模糊伴头部运动（示波器减退）；感觉失去平衡/不稳定。临床评估包括握力和腿部力量以及步行6米的步数和时间。结果：过去12个月，ags - rs II患者BDP患病率为40.1%（男性35.2%，女性43.7%），下降患病率为23.0%（男性20.9%，女性24.8%）。BDP增加了步行6米的步数和时间。BDP增加了跌倒的风险（调整患病率比[PR] = 1.53； age - rs I的95%置信区间[CI]: 1.34-1.76， age - rs II的PR = 1.77, 95% CI: 1.55-2.03）。≥2次跌倒的患病率为8.9% （BDP患者为15.6%，无BDP患者为4.4%）。在下降≥2次的患者中，70.4%的患者在过去12个月内报告了BDP。额外的跌倒风险与恐惧/惊恐发作、记忆丧失、听力丧失和其他健康状况有关。结论：BDP在老年人中很常见，与跌倒风险增加50% - 80%相关，跌倒≥2次的风险甚至更大。对进一步增加跌倒风险的因素提供了定量估计。证据等级：2（前瞻性队列研究）。
