Objective:To investigate the teaching effect of flipped classroom combined with problem-based learning (PBL) in the teaching of the Diagnostic Audiology course.Methods:A total of 72 undergraduate students majoring in audiology and speech rehabilitation in the classes of 2019 and 2020 in Chongqing Medical University were enrolled as subjects, and three chapters of the Diagnostic Audiology course were selected for teaching reform. The 34 students in the class of 2019 were enrolled as control group and received lecture-based learning (LBL), and the 38 students in the class of 2020 were enrolled as experimental group and received flipped classroom combined with PBL. The teaching effect was evaluated by comparing the two groups in terms of classroom test scores, classroom participation scores, degree of satisfaction with teaching effect, and overall satisfaction with teaching. SPSS 23.0 software was used to perform the t-test, the chi-square test, and the Mann-Whitney U test. Results:The experimental group had a significantly higher classroom test score than the control group (25.95±1.21 vs. 23.21±1.55, P<0.001). In terms of classroom participation scores, the experimental group had significantly higher scores of participation in class discussion, cooperative and collaborative abilities, and questioning skills than the control group (all P<0.001). In terms of the degree of satisfaction with teaching, compared with the control group, the experimental group had significantly higher degrees of satisfaction in the dimensions such as interest in learning, mastery of theoretical knowledge, teamwork and collaboration abilities, self-learning ability, and self-presentation ( P=0.005, 0.009, 0.001, 0.016, and 0.005). In addition, the experimental group had a significantly higher degree of overall satisfaction with teaching than the control group ( P=0.006). Conclusion:Flipped classroom combined with PBL has a good teaching effect in the Diagnostic Audiology course and thus holds promise for further application.

RESUMO
Objective:To evaluate the clinical significance of neoadjuvant immunotherapy combined with chemotherapy in the treatment of larynx preservation in locally advanced hypopharyngeal squamous cell carcinoma. Methods:Patients with locally advanced HPSCC(cT3-T4aN0-N3M0) were eligible. All received 2 cycles of pembrolizumab combined with docetaxel and platinum neoadjuvant induction therapy. After two cycles, the efficacy was evaluated, followed by radical chemoradiotherapy or surgery and adjuvant chemoradiotherapy according to the efficacy. The primary endpoints were objective response rate(ORR) ,larynx-preservation(LP) rate at 3 months post-treatment and the adverse reactions during neoadjuvant therapy. Results:From December 2021 to December 2022, 10 patients with locally advanced HPSCC(cT3-T4aN0-N3M0) were enrolled. After 2 cycles of the neoadjuvant therapy, 2 patients achieved complete response(CR), 7 patients achieved partial response(PR), 1 patient was stable disease(SD), objective response rate(ORR) was 90%, and disease control rate(DCR) was 100%. 5 patients received radical chemoradiotherapy, 5 patients received surgery and adjuvant chemoradiotherapy, four of them received partial laryngectomy and partial hypopharyngeal resection surgery, and one of them received total laryngectomy and partial hypopharyngeal resection surgery. All patients were able to withstand adverse reactions of neoadjuvant therapy and successfully completed the whole treatment of HPSCC without grade 3-4 treatment-related adverse reactions. There was no recurrence or metastasis during 3-18 months of follow-up. 1 patient died of severe pneumonia 3 months after the completion of radical chemoradiotherapy. At 3 months after treatment, the larynx-preservation rate was 80%. Conclusion:Neoadjuvant immunotherapy combined with chemotherapy has good short-term efficacy and the adverse reactions were tolerable. It can improve the larynx-preservation rate of patients with locally advanced HPSCC, thus improving the prognosis and quality of life of patients.

Objective:To investigate the prognostic impact of different tumor invasion patterns in the surgical treatment of T3 glottic laryngeal cancer. Methods:A retrospective analysis was conducted on the clinical data of 91 patients with T3 glottic laryngeal cancer. Results:Among the 91 patients, 58 cases (63.7%) had anterior invasion and 33 cases (36.3%) had posterior invasion. The posterior invasion was significantly correlated with invasions of the dorsal plate of cricoid cartilage (P<0.001), arytenoid cartilage (P= 0.001), and subglottic region(P = 0.001). There was no statistical difference in survival outcomes between the total laryngectomy group and the partial laryngectomy group. But in the partial laryngectomy group, the 5-year disease-free survival(DFS) of patients with anterior invasive tumors was better than that of patients with posterior invasion tumors (HR: 4.681, 95%CI 1.337-16.393, P=0.016), and subglottic invasion was associated with worse loco-regional recurrence-free survival(LRRFS)(HR: 3.931, 95%CI 1.054-14.658, P=0.041). At the same time, we found that involvement of the dorsal plate of cricoid cartilage was an independent risk factor for postoperative laryngeal stenosis in partial laryngectomy patients (HR:11.67, 95%CI 1.89-71.98,P=0.008). Conclusion:Compared with total laryngectomy, selected partial laryngectomy can also achieve favorable oncological outcomes. Posterior invasion and subglottic extension are independent prognostic factors for recurrence of partial laryngectomy in T3 glottic laryngeal cancer, and the involvement of the dorsal plate of cricoid cartilage is associated with postoperative laryngeal stenosis. The tumor invasion pattern of laryngeal cancer should be further subdivided in order to select a more individualized treatment plan.

Objective:To investigate the diversity and clinical effect of supraclavicular island flap in repairing the defect after head and neck tumor surgery. Methods:A retrospective analysis was performed on 30 patients who received the repair of head and neck defects with supraclavicular island flaps at Department of Otorhinolaryngology Head and Neck Surgery of the First Affiliated Hospital of Chongqing Medical University from January 2017 to March 2023. The sites and types of defects, intraoperative blood loss, time of flaps preparation, areas of flaps, survival of the flaps and other complications were recorded. Results:A total of 30 patients were enrolled, including 26 males and 4 females, aged 36-82 years. Among them, 22 patients with hypopharyngeal partial defect were repaired (19 patients with ipsilateral defect and 3 patients with contralateral defect). In addition, 2 patients were repaired with contralateral pectoralis major musculocutaneous flap around the hypopharynx, the neck skin defect was repaired in 2 patients, the parotid skin defect was repaired in 2 patients, the temporal bone skin defect was repaired in 1 patient, and the cervical esophageal defect was repaired in 1 patient. The average blood loss during the operation was 8 ml, and the average time was 32 min. The flap areas ranged from 5.0 cm×4.0 cm to 20.0 cm×8.0 cm. 27 of 30 flaps survived(90.0%), and pharyngeal fistula occurred in 6 patients after operation(4 flaps survived after local dressing). One patient was complicated with venous thrombosis(the flap necrosis after local dressing). Shoulder and neck functions(lift, internal rotation and abduction) were not significantly affected in 29 patients, and the function of 1 patient with shoulder infection was not affected after treatment. Conclusion:Supraclavicular island flap is a highly vascularized axial fascial flap. It is easy to make, thin, and soft in texture, and can be used to repair different sites and types of postoperative head and neck tumor defects with a low donor site complication rate. Good results in post-operative repair of head and neck tumors are worth promoting.

RESUMO
Objective@#To investigate the incidence of occult cervical lymph node metastasis and the common neck level of metastases in cN0 laryngocarcinoma, and the relationship between the clinicopathologic features of laryngocarcinoma and cervical lymph node metastasis.@*Methods@#A total of 506 cases with cN0 laryngocarcinoma treated at the First Affiliated Hospital of Chongqing Medical University between March 2011 and March 2018 were enrolled, and their medical records and follow-up data were retrospectively analyzed. Of them, 211 cases of were glottic carcinoma in stage T1 without neck dissection and they were observed by clinical follow-up; other 295 cases, including glottic carcinoma, supraglottic carcinoma and hypopharyngeal carcinoma in stage T2-T4 were treated with surgical resection of the primary lesions and selective neck dissection. SPSS 22.0 software was used to analyze the data.@*Results@#The total incidence of cervical lymph node metastasis was 10.87%(55/506), with a lower incidence in T1 stage glottic carcinoma(6/211,2.84%) than that in other cases(49/295,16.61%). The incidence of cervical lymph node metastasis in glottic carcinoma (29/426, 6.81%) was lower than those in supraglottic carcinoma (22/71,30.99%) and subglottic carcinoma (4/9) (χ2=35.810,P<0.01).The pN+ rates of glottic carcinoma at T1, T2, T3 were 2.84%(6/211), 5.31%(6/113), 16.05%(13/81), and 19.05%(4/21), respectively (χ2=18.572, P<0.01).

RESUMO
Objective To analyze the clinical features of 258 cases of nasal-sinus benign and malignant tumors to improve the accuracy of clinical diagnosis.Methods The clinical data of 258 patients with nasal-sinus tumor confirmed by pathology were retrospectively analyzed and the clinic differences between benign and malignant tumors were compared.Results The clinic manifestations of sinonasal neoplasm were varied.The incidences of epistaxis or blood in the tears,headache,facial numbness or pain,eye pain or epiphora were significantly higher in the benign tumors group than in the malignant tumors group (P<0.05).Among 196 patients undergoing surgery,the coincidence rates of preoperative and postoperative paraffin sections were similar in the two groups (P>0.05).Among 63 surgical patients with malignant tumors,the coincidence rate of 232 incised-margin frozen sections and postoperative paraffin sections was 98.70% (229/232).Among 34 cases,the coincidence rate of frozen sections and postoperative paraffin sections was 91.18%0 (31/34),in which 6 cases were immediately intraoperative frozen,and 66.67% (4/6) of the cases that changed into malignancy from benignity were not consistent with the preoperative diagnosis of paraffin sections.Conclusion The sinonasal tumors are lacking specificity in clinical manifestations,but rapid intraoperative frozen section examination is helpful to improve the diagnosis rate;continuously frozen pathological examination should be performed in malignant tumor margins.
RESUMO
Objective To explore the imaging characteristics of common malignant sinonasal tumors for improving the diagnostic accuracy of the disease. Methods Radiological and clinical data of 78 patients with sino-nasal malignant tumors confirmed by pathological examination were retrospectively analyzed. Results Sinonasal malignant tumors lacked imaging specificity. Most of CT showed uneven soft tissue densities with unclear boundary and destruction of bone which invaded the soft tissue outside of the cavity including orbit or intra-cranium. There was moderate to remarkable enhancement of the lesion. T1WI in MR demonstrated homo-and hypo-intense signal , while T2WI revealed homo- and hyper-intense signal ,and post contrast MR imaging displayed heterogeneous con-trast enhancement. There was no significant statistical difference between CT and MRI in the detection rate of ma-lignant tumors(P > 0.05),but CT in combination with MRI improved the positive rate of detection(P < 0.05). Conclusions The imaging of sinonasal malignant tumors is complicated and lacks specificity. For complicated si-nonasal malignant tumors,enhanced CT in combination with MRI should be used to determine the nature and limi-tation of the tumor,and its relationship with the surrounding structures,resulting in improvement of the diagnostic accuracy of the disease.
RESUMO
OBJECTIVE To analyze the clinical features of 8 patients with sigmoid sinus diverticulum and to improve the level of diagnosis and treatment. METHODS The tinnitus patients were asked in detail about the history, and performed a series of routine hearing tests (pure tone audiometry, acoustic impedance audiometry, otoacoustic emission inspection and brainstem auditory evoked potential (BAEP) etc.) and temporal bone HRCT scan. Eight cases were diagnosed with sigmoid sinus diverticulum, in which six cases undertook a surgery to reconstruct the sinus wall while the other 2 cases chose conservative treatment. RESULTS The diagnosis of 6 cases was proved to be correct by surgery, and the pulsatile tinnitus disappeared after reconstructing the sinus wall. No one recurred after following up from 2 to 12 months. Two cases of conservative treatment had no obvious improvement in symptoms. CONCLUSION Clinical manifestation, hearing examination, temporal bone CT/HRCT and Cranial CTA/CTV contributed to the diagnosis of sigmoid sinus diverticulum. Sinus wall reconstruction is a better approach.
RESUMO
[ABSTRACT]OBJECTIVETo study the therapeutic efficacy of Montelucast and Cetirizine on allergic rhinitis in children and their effects on the level of serum IFN-γ and IL-4.METHODS Sixty allergic rhinitis children were randomly divided into treatment group (30 children) and control group (30 children). The control group were treated with cetirizine drops (po, ages 2-6, 5 mg, qd, ages >6, 10 mg, qd.). Treatment group were treated with cetirizine drops combined with Montelucast (po, ages 2-5, 4 mg, qn, ages 6-12, 5 mg, qn, ages >12, 10 mg.). Thirty health children were selected as health group.RESULTSBefore treatment, the level of serum IFN-γ in treatment group and control group were significantly lower than that in health group (P0.05). After treatment, the level of serum IFN-γ of both groups increased, and the level of serum IL-4 of both groups decreased. However, the level of serum IL-4 and IFN-γ in treatment group changed significantly (P<0.01). After treatment, VAS scores were lower than that of before treatment, however that of the treatment group was the lowest (P<0.01). After one month follow-up, there was no significant difference between the two groups.CONCLUSIONThe mechanism of Montelucast and cetirizine on treatment of allergic rhinitis may be related to the correction of the disorder of IFN-γ and IL-4.
