Objective:To compare the clinical value of visual analogue scale （VAS）, Lebel scale and total nasal symptom scores （TNSS） in evaluating nasal allergen provocation test （NAPT）. Methods:A total of 151 patients suspected of allergic rhinitis admitted to the Department of Otolaryngology-Head and Neck Surgery of our hospital from April 2020 to September 2020 were included, of which 76 were positive for house dust mites and 75 were negative for allergens. Nasal airway resistance（NAR） was measured by active anterior nasal manometry. Nasal symptoms were evaluated by VAS, Lebel and TNSS. House dust mite allergen was used for NAPT by spray method. An increase≥40% in NAR was used as the gold standard for objective evaluation of NAPT. ROC curves of VAS, Lebel and TNSS were drawn to compare the evaluation effectiveness of different subjective evaluation methods, and the optimal critical point of each ROC curve was obtained. Results:With NAR increased by ≥40% as the gold standard, the area under ROC curve of VAS was 0.884, and the sensitivity and specificity were 97.75% and 80.65%, respectively. The area under ROC curve of Lebel was 0.773, and the sensitivity and specificity were 68.54% and 75.81%, respectively. The area under ROC curve of TNSS was 0.792, and the sensitivity and specificity were 68.54% and 79.03%, respectively. There was no significant difference between Lebel and TNSS（P>0.05）. The VAS differed significantly from Lebel and TNSS（P<0.05）. The Kappa values of VAS, Lebel, TNSS and NAR were 0.803, 0.432 and 0.459, respectively. Conclusion:The VAS, Lebel, TNSS subjective scale and NAR are consistent in evaluating the efficacy of NAPT, with the VAS assessment showing highest consistency with NAR. As objective assessment instruments are not widely used in China, subjective assessment method could be adopted to evaluate the efficacy of NAPT in clinical practice, and VAS scale is recommended as a priority.

Objective:To explore the distribution of airborne pollen in summer and autumn in Taiyuan, analyze the correlation between pollen characteristics, meteorological factors and allergic sensitization, and provide for the prevention and treatment of allergic diseases in this. Methods:The gravity sedimentation method was used to investigate the types, quantities and dispersion patterns of airborne pollen in Taiyuan City from July 21, 2022 to October 20, 2022. he meteorological and patient information was collected during the same period SPSS 26.0 software. Results:①A total of 17 118 pollen grains were collected, and identified as 14 families, 10 genera, and 4 species. The peak period for pollen dispersal in summer and autumn in Taiyuan City from late August to early September. airborne pollen Artemisia（66.62%）, Cannabis/Humulus（17.79%）, Sophora japonica（8.18%）, Chenopodiaceae/Amaranthaceae（2.83%）, Gramineae（2.11%）. ②The concentration of airborne pollen in Taiyuan City positively correlated with the average temperature（5-20℃） and maximum temperature（11-30℃） within a certain range（r=0.547, 0.315, P<0.05）. ③The content of airborne pollen in Taiyuan City positively correlated with the number of visits and allergen positive rate of patients with allergic rhinitis（AR） in our hospital（r=0.702, 0.747, P<0.05）. Conclusion:The peak period for airborne pollen dispersal during the summer and autumn seasons in Taiyuan City from late August to early September. The dominant pollen is Artemisia, Cannabis/Humulus, Sophora japonica, Chenopodiaceae/Amaranthaceae, Gramineae, and the absolute advantage pollen is Artemisia. Meteorological factors pollen content. Within a certain range, temperature the diffusion and transportation of pollen. The number of pollen grains the number of visits, which can serve as an environmental warning indicator for AR patients to take preventive, thereby reducing the risk of allergies.

Objective:To investigate the value of nasal provocation test（NPT） in evaluating the efficacy of allergen immunotherapy（AIT） in patients with dust mite induced allergic rhinitis（AR）. Methods:A total of 83 patients with dust mite induced AR with/without asthma were included. Symptom score（SS）, daily medication score（DMS）, combined symptom and medication score（CSMS）, rhinoconjunctivitis quality of life questionnaire（RQLQ）, NPT and skin prick test（SPT） were assessed before and after 1 year AIT. Results:There were statistical differences in SS（P<0.000 1）, DMS（P<0.000 1）, CSMS（P<0.000 1）, and RQLQ（P<0.000 1） after 1 year of AIT compared with pre-treatment. The effective rate of CSMS was 73.49%, and the effective rate of NPT was 42.17%. CSMS was consistent with NPT in efficacy assessment（Kappa=0.437, P<0.001）; while in 54 patients with pre-treatment NPT concentrations other than the original concentration, CMSM and NPT showed better consistence（Kappa=0.895, P<0.001）. Among the 48 patients with ineffective NPT assessment in the first year, 25 patients completed the second-year follow-up, and 12 patients（48.00%） showed effective in NPT. However, 10 out of 12 patients（83.33%） with NPT concentration other than original solution pre-treatment showed effective NPT at the second year. Conclusion:NPT can be used as one of the indicators for efficacy evaluation for dust mite induced AR patients, especially for patients with positive NPT induced at lower concentrations before treatment.

The allergen nasal provocation testing（NPT）, in which allergens are applied directly to the nasal mucosa under standard and controlled conditions to provoke the main symptoms of allergic rhinitis（AR）, reproduces the response of the upper respiratory tract to natural exposure to allergens under controlled conditions and is the only test currently available to confirm nasal reactivity to allergens. It is invaluable in studying the mechanisms of AR and in assessing the response to novel anti-allergic treatments. The test may play an increasingly important role in clinical practice, especially in the identification of local AR, the diagnosis of occupational AR, the clarification of the composition of allergens, the assessment of the efficacy of AR treatment and the selection of candidates undergoing allergen immunotherapy. This article reviewed the application of NPT in the diagnosis of allergic and non-allergic rhinitis, and also introduces the indications, contraindications, advantages and limitations of NPT in evaluating nasal response.

Objective:To monitor adherence to specific sublingual immunotherapy （SLIT） in patients with seasonal allergic rhinitis（AR）, analyse factors influencing adherence, and provide research support to effectively improve adherence. Methods:Patients with AR who underwent Artemisia pollen SLIT at the Department of Otolaryngology-Head and Neck Surgery, First Hospital of Shanxi Medical University from May 2021 to April 2022 were retrospectively followed up by telephone to investigate the current status of treatment, count the causes of shedding, and extract relevant information from their medical record data for analysis. Results:Of the 112 patients surveyed, 34 discontinued treatment（30.3%）; patients who experienced adverse reactions and SLIT patients who had been on treatment for more than 6 months showed relatively good adherence（P<0.05）. The main reasons for discontinuation in patients who dropped out were: asymptomatic discomfort during the non-pollen phase and therefore discontinuation of treatment or feeling that treatment was ineffective 9 cases（26.5%）, forced discontinuation due to vaccination or pregnancy, or epidemics 6 cases（17.6%）. Conclusion:Long-term adherence of patients to Artemisia pollen SLIT still needs to be brought to the attention of healthcare professionals, especially in the early stages of treatment when good patient education and good channels of trust and communication between doctors and patients need to be established.

Infants with laryngotracheal anomalies are clinically manifested as stridor or noisy breathing, choking, hoarseness, feeding difficulties, and cyanotic spells, followed by developmental and growth retardation and other health issues; in severe cases, patients may present with severe dyspnea, which is associated with high mortality. A timely diagnosis as well as appropriate strategy for laryngotracheal anomalies is still challenging for pediatric otolaryngologists. This consensus statement, evolved from expert opinion by the members of the Pediatric Otorhinolaryngology Professional Committee of the Pediatrician Branch of the Chinese Medical Doctor Association, provides comprehensive recommendations and standardized guidance for otolaryngologists who manage infants and young children with laryngotracheal anomalies in evaluation and treatment based on symptomatology, physical and laboratory examinations.

Objective:To investigate the classification of head shaking nystagmus（HSN） and its clinical value in vestibular peripheral diseases. Methods:Clinical data of 198 patients with peripheral vestibular disorders presenting with HSN were retrospectively analyzed. Video Nystagmograph（VNG） was applied to detect spontaneous nystagmus（SN）, HSN, and Caloric Test（CT）. The intensity and direction of SN and HSN as well as the unilateral weakness（UW） and direction preponderance（DP） values in caloric test was analyzed in patients. Results:Among the 198 patients with vestibular peripheral disease, there were 105 males and 93 females, with an average age of（49.1±14.4） years （range: 14-87 years）. One hundred and thirty seven patients were diagnosed as Vestibular Neuritis（VN）, 12 as Meniere's Disease（MD）, 41 as sudden deafness（SD） and 8 as Hunt's syndrome accompanied by vertigo. Among them, there were 116 patients in the acute phase, including 68 cases（58.6%） with decreased HSN, 4 cases（3.4%） with increased HSN, 5 cases（4.3%） with biphasic HSN, 38 cases（32.8%） with unchanged HSN, and 1 case（0.9%） with perverted HSN. There were 82 cases in the non-acute phase, 51 cases（62.2%） with decreased HSN, 3 cases（3.6%） with increased HSN, 9 cases（11.0%） with biphasic HSN, and 19 cases（23.2%） with unchanged HSN. In biphasic HSN, the intensity of phase I nystagmus was usually greater than that of phase II, and the difference was statistically significant（P<0.01）. There was no correlation between HSN type and course of disease or DP value. The intensity of HSN was negatively correlated with the course of disease（r=-0.320, P<0.001） and positively correlated with DP value（r=0.364, P<0.001）, respectively. The intensity of unchanged nystagmus and spontaneous nystagmus were（8.0±5.7） °/s and（8.5±6.4）°/s, respectively. There was no statistically significant difference in the intensity of nystagmus before and after shaking the head. Conclusion:HSN can be classified into five types and could be regarded as a potential SN within a specific frequency range （mid-frequency）. Similarly, SN could also be considered as a common sign of unilateral vestibular impairment at different frequencies. HSN intensity can reflect the dynamic process of vestibular compensation, and is valuable for assessing the frequency of damage in peripheral vestibular diseases and monitoring the progress of vestibular rehabilitation.

Objective:To analyze the correlation between nasal resistance and lung function in children with allergic rhinitis（AR）, and explore whether AR children with increased nasal resistance are accompanied by potential lower respiratory tract involvement. Methods:A total of 88 children diagnosed with AR from December 2021 to December 2022 were selected as the study group, while 20 normal children were selected as the control group during the same period. Both the study group and the control group children underwent lung function tests, bronchodilator tests, and nasal resistance measurements. Spearman correlation analysis and multiple linear regression analysis were performed on the results of nasal resistance and lung function tests to explore the relationship and influencing factors between the two groups.According to the results of nasal resistance measurement, children with increased nasal resistance and abnormal lung function were divided into a mild increase in nasal resistance with abnormal lung function group and a moderate to severe increase in nasal resistance with abnormal lung function group. The degree of increased nasal resistance was analyzed to determine whether it would affect lung function. Results:The FEF25, FEF50, and FEF75 levels in the study group were significantly lower than those in the control group（P<0.05）. The FEV1of children with moderate to severe increase in AR nasal resistance was significantly lower than that of children with mild increase in AR nasal resistance（P<0.05）. There was a correlation between nasal resistance and FEV1/FVC, R20 in AR children, and FEV1/FVC, R20 were the influencing factors of nasal resistance in AR children（P<0.05）. There was no correlation between total serum IgE, lung function, and bronchodilation test in AR patients（P>0.05）. Conclusion:The nasal ventilation function of AR patients has changed, and there is a downward trend in small airway function. Children with moderate to severe increase in AR nasal resistance have a more significant decrease in lung ventilation function than those with mild increase. The nasal resistance of AR children is influenced by FEV1/FVC and R20, and FEV1/FVC and R20 decrease as the nasal resistance value increases. The improvement rate of lung function and FEV1 are not influencing factors for the elevation of total serum IgE.

Microorganisms are one of the important factors which maintain the homeostasis of human health. Despite recent advances, the relationship between microorganisms and head and neck squamous cell carcinoma （HNSCC） is still unclear, and the impact of microorganisms on the incidence and prognosis of HNSCC cannot be neglected. Therefore, this article provides a systematic and comprehensive review summarizing the epidemiological evidence of microbial dysbiosis related to HNSCC and discusses the associations between them.

Objective:To report the experience of using CT-guided cochlear implant surgery in difficult cases such as severe inner ear deformities and anatomical abnormalities, and to discuss the application value of intraoperative CT-assisted localization in difficult cases of cochlear implant surgery. Methods:Retrospectively analyzed the clinical data of 23 cases of difficult cochlear implant surgery cases completed by our team with the assistance of intraoperative CT, and collected their medical data, including preoperative imaging manifestations, surgical conditions, and intraoperative imaging images for evaluation. Results:During the study period, 23 difficult cases（27 ears） underwent cochlear implantation under the guidance of intraoperative CT, and 4 cases were bilaterally implanted. Including 6 cases of incomplete segmentation type Ⅰ（IP-Ⅰ）, 1 case of incomplete segmentation type Ⅱ（IP-Ⅱ）, 10 cases of incomplete segmentation type Ⅲ（IP-Ⅲ）, 3 cases of common cavity deformity（CC） and 3 cases of cochlear ossification after meningitis. Facial nerve anatomy was abnormal in 9 cases, cerebrospinal fluid "blowout" was serious in 14 cases, electrode position was abnormal in 3 cases requiring intraoperative adjustment of electrode position, anatomical difficulties required intraoperative CT to assist in finding anatomical landmarks in 2 cases, and electrodes were not fully implanted in 3 cases. Conclusion:When faced with difficult cases with challenging and complex temporal bone anatomy, intraoperative CT can accurately evaluate the electrode position and provide intraoperative anatomical details, allowing immediate adjustment of the electrode position if necessary, providing safety guarantee for difficult cases of cochlear implant surgery and ensure accurate implantation of electrodes.
