导论.了解喉的形态，人体最复杂的器官之一，是了解详细的喉解剖学和生理学的重要一步。不同的研究描述了喉的线性测量在不同的测量方法，但还没有研究已经结构化描述声带长度在新鲜切除的喉。本研究的目的是描述在新鲜切除的喉声带和一些喉结构的精确解剖测量，并比较男性和女性之间的测量。这可以帮助提高诊断和治疗程序在喉领域。本研究应用于21例不同类型的喉癌患者，其中男性11例，女性10例，年龄范围41-75岁。每例患者均使用喉内窥镜检查和摄影进行评估，并使用毫米级标尺测量膜状声带的长度，该标尺使用与声门视频喉镜检查中使用的相同放大倍数进行聚焦摄影。然后，患者暴露于全喉切除术，切除的喉用于直接测量膜和软骨声带。然后对男性和女性的指标进行统计比较。切除喉的测量也与使用视频打印尺的视频内窥镜进行了比较。新鲜切除的喉可用于准确定量测量声带长度和喉部尺寸。男女之间在所有测量的方面都有相当大的差异。
Introduction. Understanding the morphology of the larynx, one of the most complex organs of the human body, is an important step toward understanding the detailed laryngeal anatomy, and physiology. Different studies have described the linear measurements of the larynx in different measuring methods, but no studies have been structured to describe vocal fold length in freshly excised larynges.Objectives. The aim of this study was to describe exact anatomical measurements of vocal folds and some laryngeal structures in freshly excised larynges, and to compare such measurements between males and females. This can help improve the diagnostic and therapeutic procedures in the laryngology field.Subjects and Methods. This study was applied on 21 patients having different types of laryngeal carcinoma: 11 males and 10 females with the age range 41-75 years old. Every patient was assessed using laryngeal endoscopy and photography, and the length of the membranous vocal fold was measured using a millimeter-graded ruler that was photographed with focus with the same magnification used in the video laryngoscopy of the glottis. Then patients were exposed to total laryngectomy, and excised larynges were used for a direct measuring of the membranous and carti-laginous vocal folds. Then measures of men and women were compared statistically. Measures of excised larynges were also compared with those of the video endoscopy using a video-printed ruler.Conclusion. Freshly excised larynges can be used for accurate quantitative measuring of the vocal fold length and laryngeal dimensions. There are considerable differences in all measured dimensions between males and females.
