This series aimed to show the safety and efficacy of drainless day case parotidectomy using ARTISS [Solution for Sealant] fibrin glue. <strong>Materials and Methods:</strong> Patients with a superficial parotid lump with benign preoperative sampling underwent an SP. We initially used both ARTISS and a drain, which was removed when output was <40 mls. ARTISS without drain was then introduced and once confident patients were sent home the same day. <strong>Objectives:</strong> We prospectively collected data and divided groups into ARTISS alone and ARTISS with a drain to compare patients’ length of stay and complication rates. <strong>Results:</strong> 88 patients were included;52 ARTISS alone, 22 as a day case. 42.3% of patients where ARTISS alone was used were discharged within 24 hours, with the remainder between 24 - 48 hours. Comparatively, no ARTISS and drain patients were discharged within 24 hours and 86.1% were discharged between 24 - 48 hours with the remainder over 48 hours. There were 3 postoperative haematomas and none in the drainless group;a statistically significant difference (<em>p</em> = 0.034). Of the 6 recorded salivary leaks, 4 were in the drain group and 2 in the ARTISS alone group (<em>p</em> > 0.05). <strong>Conclusions:</strong> Comparable complication rates and reduced length of stay suggest that ARTISS in SP is safe and effective. These findings stand to benefit both patients and the NHS by improving the patient journey and reducing overall costs.展开更多

Although its local recurrence rate is known to be high, the recurrence extending to the cervical region is rare. Here we report a case of a young female (25 years old) with pleomorphic adenoma of the parotid gland which showed multiple recurrences through facial to cervical regions over a span of eight years. We also discuss how this benign tumor with a high recurrence rate has been treated in other cases, and how it should be treated.展开更多

Conclusion: Consideration of the higher residual tumor rate in patients who received non-standard operations,the re-operations were necessary.Contrast-enhanced CT positive predictive value was high for residual tumor and it was important for re-operation.展开更多

Very little material on this topic has been published. This tumour represents a therapeutic challenge since there are no specific recommendations or guidelines. We present a case of malignant myoepithelioma arising de novo in the parotid gland. We discuss our therapeutic approach and considerations on appropriate post-surgical treatment. Then we provide a review of international literature on this interesting and rare oncological entity.展开更多
文摘目的:探讨SHAP值在极端梯度提升(Extreme gradient boosting,XGBoost)MRI模型中鉴别腮腺恶性肿瘤(Malignant tumor,MT)与Warthin瘤(Warthin tumor,WT)的价值。方法:回顾分析经手术病理证实的22例22枚MT和38例51枚WT的MRI资料,分析瘤体形态、位置和强化方式,以及T_(1)WI、T_(2)WI、FS-T_(1)WI、FS-T_(2)WI影像征象,经单因素分析筛选有统计学意义的征象,纳入XGBoost模型,使用受试者工作特征曲线下面积(Area under the curve,AUC)、敏感度、特异度评价模型诊断效能。通过可解释机器学习模型(Shapley additive explanations,SHAP)值对模型进行分析,明确各MRI征象在模型中的权重。结果:22枚MT和51枚WT中,持续性强化(P<0.05)、形态不规则(χ^(2)=20.707,P<0.05)、非尾叶(χ^(2)=8.911,P<0.05)、T_(2)WI高信号(χ^(2)=7.581,P<0.05)、FS-T_(1)WI等低信号(P<0.05)、FS-T_(2)WI高信号(χ^(2)=9.016,P<0.05)对鉴别两者有统计学意义,且均更常见于MT中。将6项单因素纳入XGBoost模型分析得出AUC为0.847,敏感度为77.3%,特异度为92.2%;6种MRI征象绝对平均SHAP值为0.21~0.99,其中形态不规则权重最大。结论:形态不规则、T_(2)WI高信号、持续性强化、FS-T_(2)WI高信号、非尾叶、FS-T_(1)WI等低信号对MT和WT鉴别的权重存在差异,对各MRI征象的准确识别,有利于对两者精准诊断。
