Expert consensus on odontogenic maxillary sinusitis multi-disciplinary treatment

Odontogenic maxillary sinusitis (OMS) is a subtype of maxillary sinusitis (MS). It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion. Due to the lack of unique clinical features, OMS is difficult to distinguish from other types of rhinosinusitis. Besides, the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis. Its current diagnosis and treatment are thus facing great difficulties. The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS. However, this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality. Based on systematically reviewed literature and practical experiences of expert members, our consensus focuses on characteristics, symptoms, classification and diagnosis of OMS, and further put forward multidisciplinary treatment decisions for OMS, as well as the common treatment complications and relative managements. This consensus aims to increase attention to OMS, and optimize the clinical diagnosis and decision-making of OMS, which finally provides evidence-based options for OMS clinical management.

Effect of nursing intervention on rehabilitation of patients with chronic sinusitis and nasal polyps after nasal endoscopy

BACKGROUND Chronic sinusitis is a kind of chronic suppurative inflammation of the sinus mucosa.Nasal endoscopy is a good method to treat nasal polyps.However postoperative rehabilitation and care should not be neglected.AIM To investigate the Effect of nursing intervention on the rehabilitation of patients with chronic sinusitis and nasal polyps(CSNPS)after nasal endoscopy.METHODS A total of 129 patients with CSNPS hospitalized from February 2017 to February 2019 were studied.Using the digital parity method,we investigated nursing cooperation strategies for endoscopic surgery.The comparison group(64 cases):Surgical nursing was carried out with traditional nursing measures;experimental group(65 cases):Surgical nursing was carried out by traditional nursing countermeasures+comprehensive nursing measures.We compared postoperative recovery rates,nursing satisfaction rates,and nasal cavity ratings between the two groups.RESULTS Experimental group patients with CSNPS had a significantly higher recovery rate(98.46%)compared to the control group(79.69%).This difference was statistically significant(χ2=11.748,P<0.05).Additionally,the satisfaction rate with treatment was also significantly higher in the experimental group(98.46%)compared to the control group(79.69%),with a statistically significant difference(χ2=11.748,P<0.05).Before nursing,there was no significant difference in sinus nasal cavity scores between the experimental group(20.29±7.25 points)and the control group(20.30±7.27 points)(t=0.008,P>0.05).However,after nursing,the sinus nasal cavity score in the experimental group(8.85±3.22 points)was significantly lower than that in the control group(14.99±5.02 points)(t=8.282,P<0.05).CONCLUSION Comprehensive nursing intervention in patients with CSNPS can significantly improve the total recovery rate after endoscopic surgery.

Real World Evidence (RWE, Real World Data), of the Effectiveness of Amoxicillin-Clavulanate in the Treatment of Children with Upper Respiratory Tract Infections (Tonsillitis, Otitis, Sinusitis)

Real-world evidence (RWE) is clinical evidence on a medical product’s safety and efficacy that is generated using real-world data (RWD) resulting from routine healthcare delivery. This study evaluates the clinical efficacy of amoxicillin + clavulanic acid in children with pharyngitis, acute otitis, or acute rhinosinusitis with suspected bacterial origin under normal office and home conditions. Methods: This was a real-life, prospective, observational, pharmacovigilance study. It included children of both sexes between 2 and 12 years old, with a diagnosis of Rhinopharyngitis (tonsillitis), Acute Otitis Media and Rhinosinusitis. The main effectiveness variable evaluated was reduction and time to resolution of symptoms. All patients received Amoxicillin/Clavulanic Acid suspension 600 mg/42.9 mg/5 mL at a dose of 90 mg/Kg/day in two doses, every 12 hours for 7 days. The evaluations were carried out at the beginning, at 72 hours (3rd day) and at 7 days. All patients underwent culture and antibiogram. Results: The majority of cultures were negative for pathogenic germs, suspecting unidentifiable germs, or viral etiology despite the rigorous selection of subjects following validated scores. The most frequently isolated germ was Staphylococcus aureus;growth of gram-negative bacteria was reported in 33.33% of the cultures. There was a significant improvement in symptoms in children with tonsillitis and rhinosinusitis from the first 72 hours of treatment, persisting until the 7 days. In the otitis media group, returning to normal by the tenth day. During the conduction of this investigation, no adverse effects associated with the prescribed therapy were reported.

Association of Comorbid Asthma and the Efficacy of Bioabsorbable Steroid-eluting Sinus Stents Implanted After Endoscopic Sinus Surgery in Patients with Chronic Rhinosinusitis with Nasal Polyps

Objective To identify factors affecting the efficacy of steroid-eluting sinus stents implanted after endoscopic sinus surgery(ESS)in patients with chronic rhinosinusitis with nasal polyps(CRSwNP).Methods We performed a post-hoc analysis of a randomized self-controlled clinical trial on post-operative implantation of bioabsorbable steroid-eluting stents in patients with CRSwNP.Univariate logistic regression analysis was conducted to identify which of the following factors affect the response to post-operative stent implantation:sex,serum eosinophil levels,history of prior surgery,endoscopic scores,and comorbid conditions(asthma and allergic rhinitis).The primary outcome was the rate of post-operative intervention on day 30,and the secondary outcome was the rate of polypoid tissue formation(grades 2–3)on days 14,30,and 90.Results A total of 151 patients with CRSwNP were included in the post-hoc analysis.Asthma was identified as the only risk factor for a poor response to steroid-eluting sinus stents on post-operative day 30,with an odds ratio of 23.71(95%CI,2.81,200.16;P=0.004)for the need for post-operative intervention and 19(95%CI,2.20,164.16;P=0.003)for moderate-to-severe polypoid tissue formation.In addition,the asthmatic group showed higher rates of post-operative intervention and polypoid tissue formation than the non-asthmatic group on post-operative day 30.Blood eosinophil levels were not identified as a risk factor for poor outcomes after stent implantation.Conclusion Comorbid asthma,but not blood eosinophil level,impairs the efficacy of steroid-eluting sinus stents in the short term after ESS in patients with CRSwNP.

Socioeconomic Status Impacts the Prognosis of Chronic Rhinosinusitis Treated by Endoscopic Sinus Surgery:An Observational Cohort Study in Northeast China

Objective To explore the association between socioeconomic status(SES)and postoperative outcomes in patients with chronic sinusitis(CRS)after functional endoscopic sinus surgery(ESS).Methods We conducted an observational cohort study of 1,047 patients with CRS undergoing ESS.Discharged patients were followed up to 72 weeks for all-cause recurrence events.Baseline SES was established based on occupation,education level,and family income of the patients 1 year before the operation.Kaplan–Meier method was used to calculate the recovery rate after ESS,and Cox proportional hazards regression analysis was used to evaluate the relationship between SES and prognosis.Results Patients of middle SES had lower unadjusted all-cause recurrence than those of low or high SES;24-week overall recovery rate was 90.4%[95%confidence interval(CI):89.6%–91.2%]in patients of middle SES,13.5%(95%CI:12.8%–14.2%)in patients of low SES,and 31.7%(95%CI:30.7%–32.7%)in patients of high SES(both log-rank P<0.001).After adjustment for covariates,hazard ratios(HRs)were7.69(95%CI:6.17–9.71,Ptrend<0.001)for all-cause recurrence for low SES versus middle SES,and 6.19(95%CI:4.78–7.93,Ptrend<0.001)for middle SES versus high SES.Conclusion Low SES and high SES were more associated with the worse prognosis of CRS patients after ESS than middle SES.

Study on the Impact of Cognitive Nursing Model on Postoperative Quality of Life in Patients Undergoing Chronic Sinusitis Surgery

Objective:To explore effective nursing programs for surgical patients with chronic sinusitis(CS).Methods:62 CS surgery patients were randomly divided into a research group and a control group with 31 cases in each group.The patients in the research group received cognitive nursing care,while the patients in the control group received routine nursing care.The nursing effects of the two groups were compared.Results:The postoperative quality-of-life scores,health behavior scores,complication rates,and nursing satisfaction scores of the patients in the research group were all better than those of the control group(P<0.05).Conclusion:The cognitive nursing model significantly improves the condition of CS surgery patients,thus it should be popularized.

伴有骨质破坏的单侧慢性细菌性上颌窦炎的临床研究

目的探讨伴有骨质破坏的单侧慢性细菌性上颌窦炎的临床特点及其相关因素。方法对2021年1月至2022年12月宁夏医科大学总医院耳鼻咽喉头颈外科收治的44例伴有骨质破坏的单侧慢性细菌性上颌窦炎患者的电子鼻咽镜下特点、影像学特点、细菌培养结果等进行临床分析。结果44例患者的主要症状与其他鼻窦炎相比无特殊性。镜下所见患侧鼻腔中鼻道向内膨隆、黏膜水肿、大量白色脓涕潴留并脱向鼻咽部。影像学特点,CT表现为单侧上颌窦腔内均匀低密度影填充,上颌窦口周围有骨质破坏,其中钩突尾端破坏最显著;MRI表现为T1窦壁黏膜呈高信号,增强后明显强化,患侧上颌窦腔内呈均匀低信号,增强后无强化,T2患侧上颌窦腔内见囊液性信号填充,中心可见斑片状高信号影,窦壁黏膜呈结节样增厚。在结构上,与健侧相比,患侧筛泡截面积比健侧大(P<0.05),鼻窦炎在鼻中隔偏曲患者的狭窄侧比宽敞侧多(P<0.05);一般细菌培养阳性率为77.27%(34/44)。共分离出9种细菌,排在前3名的菌种依次为凝固酶阴性葡萄球菌40.91%(18/44)、草绿色链球菌31.82%(14/44)和星座链球菌9.09%(4/44)。结论单侧慢性细菌性上颌窦炎的骨质破坏仅限于上颌窦口周围,以钩突尾端破坏为主;患侧筛泡肥大、鼻中隔偏向患侧可能是窦口阻塞的影响因素;葡萄球菌与链球菌可能是此类鼻窦炎的致病菌。
