Most laryngeal cancers originate in the glottis, with supraglottic and subglottic tumours being less frequent. Laryngeal cancer may spread by: direct extension to adjacent structures, metastasis to regional cervical lymph nodes, or via the blood stream. The most common site of distant metastases is the lung. Laryngeal cancer occurred in 177,000 ...
The glottis (pl.: glottises or glottides) is the opening between the vocal folds [1] (the rima glottidis). [2] The glottis is crucial in producing sound from the vocal folds. Etymology
The rima glottidis is the narrowest part of larynx. It is longer (~23 mm) in males than in females (17–18 mm). [1]The rima glottidis is an aperture between the two true vocal cords anteriorly, and the bases and vocal process of the two arytenoid cartilages posteriorly.
The length of the vocal fold at birth is approximately six to eight millimeters and grows to its adult length of eight to sixteen millimeters by adolescence.
