Management of cancer of the base of tongue

The management of base of tongue cancer has evolved steadily over time. Organ preservation with primary radiation therapy has produced excellent oncologic and functional outcomes. Concomitant chemotherapy has become important in patients with locoregionally advanced disease. Planned neck dissection after organ preservation therapy continues to be an integral step for regional control. This article reports the results of a literature review of base of tongue cancer emphasizing a multidisciplinary approach to obtain optimal results in terms of cure and quality of life.     

耳廓开放性外伤的治疗方法探析

目的 探讨耳廓开放性外伤的治疗方法。方法 23耳耳廓开放性外伤经彻底清创，肝素生理盐水冲洗伤口后，对位缝合。术后用抗生素抗感染、丹参扩张血管、罂粟碱改善微循环。结果 23耳中2耳失访，18耳完全成活，1耳部分成活，2耳完全坏死。结论 耳廓撕裂伤、断伤、带有皮蒂的耳廓离断伤，由于断端双侧血管丰富，经对位缝合后容易成活。但耳廓完全离断伤由于缺乏血供，经对位缝合后不易成活，可采用去皮血管植入包埋法，带肌蒂皮瓣移植法或尝试显微外科技术施行血管吻合，以提高耳廓完全离断伤的成活率。     

Methods of analysis of large numbers of audiograms

The analysis of large numbers of audiograms raises the question if and how we can reduce the amount of data without discarding essential information. The present paper compares two ways of data reduction: principal-component analysis and curve fitting. The methods are tested on the audiograms of a large family suffering from a dominant hereditary, progressive hearing loss, beginning in the high frequencies. It is shown that principal-component analysis rejects information on the shape of the audiogram, as do all methods generally referred to as factor analysis. The information concerned is essential for our understanding of the patient's ability to discriminate speech. Curve-fitting procedures are shown to be effective in data reduction.     

不同证型耳鸣特点探讨

尝试以听力学检测手段定量分析虚实两类四种证型的耳鸣特点,对其龙频率分布、耳鸣响度及与听力损害类型等方面作观察与探讨。认为两组在频率分布、响度的定量指标上,在听力损害类型方面有显著性差异,组内各证型间也有显著性差异,这咱客观指标可作为临床辨证辨症病的参考。     

舌根癌手术治疗2例报告

目的探讨手术治疗舌根癌的方法.方法分别为2例舌根癌患者实施咽侧入路及下颌骨正中裂开外旋入路切除肿瘤,应用胸骨舌骨肌肌筋膜瓣和胸大肌肌皮瓣修复缺损.结果2例患者切口均一期愈合,经锻炼逐步恢复了吞咽及语言功能;术后10月和18月复发.结论术前充分检查,准确评估肿瘤范围是选择合适的术式,彻底切除肿瘤的前提;咽侧入路及下颌骨正中裂开外旋入路是切除舌根癌最常用的有效手术径路;胸骨舌骨肌肌筋膜瓣和胸大肌肌皮瓣修复是两种有效的修复方法,前者对术后吞咽、语言功能的影响较小,后者可修复局部较大的组织缺损.
