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.
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.
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 cartilaginous 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.
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.
了解喉部这一人体最复杂的器官之一的形态，是迈向理解喉部详细解剖结构和生理学的重要一步。不同的研究以不同的测量方法描述了喉部的线性测量，但尚未有研究系统地描述新鲜切除喉部的声带长度。
本研究的目的是描述新鲜切除喉部中声带和一些喉部结构的确切解剖测量值，并比较男性和女性之间的这些测量值。这有助于改进喉科学领域的诊断和治疗程序。
本研究应用于21例患有不同类型喉癌的患者：11名男性和10名女性，年龄范围为41 - 75岁。每位患者均接受喉镜检查和摄影评估，并使用毫米刻度尺测量膜性声带长度，该尺子在与声门视频喉镜相同放大倍数下聚焦拍摄。然后对患者进行全喉切除术，切除的喉部用于直接测量膜性和软骨性声带。随后对男性和女性的测量值进行统计学比较。还使用视频打印尺将切除喉部的测量值与视频内镜检查的测量值进行比较。
新鲜切除的喉部可用于准确量化测量声带长度和喉部尺寸。男性和女性在所有测量维度上存在显著差异。
