=Ulceration= of the larynx commences in the mucous membrane, but may extend to the deeper parts. The more usual location is upon the epiglottis, or on the margin of the glottis and vocal cords. Impairment of the voice to a greater or less degree, will have attended either inflammation or ulceration of the vocal cords. It is to be borne in mind, however, that aphonia may arise from some impairment of the nerves of the larynx, in which case, a post-mortem examination will fail to reveal any morbid condition of the mucous membrane or vocal cords. Pulmonary consumption we sometimes find accompanied with the presence of ulcers upon the posterior walls of the larynx, with evidence of inflammation in the surrounding parts. Whether these arise from tubercles in the mucous membrane, or ulceration of the mucous follicles, is uncertain. =Œdema= of the larynx, is attended with great swelling of the mucous membrane, from serous effusion into the submucous tissues, and frequently attends chronic inflammation of the parts, with ulceration. It may, however, be of an erysipelatous character, occurring as the result of exposure to infection. The surface appears red, pulpy and swollen, from infiltration of the submucous tissue. Œdema of the larynx, is confined to the parts around the epiglottis, and margins of the glottis, never descending below the true vocal cords, owing to the close adhesion of the mucous membrane to the fibrous structure of the cord, without any intervening areolar tissue. =Necrosis of the Cartilages= of the larynx, may occur in the advanced stage of laryngitis with ulceration. In this manner the epiglottis, with the arytenoid, the cricoid, and even thyroid cartilages may, to a greater or less extent, be destroyed. =Abscesses= may also form, where the cartilages are so much involved, these in some cases breaking upon the outside, and establishing fistulous communications through which air may escape during respiration. =Tumors= of the larynx, may be found _first_, outside of the cavity, imbedded in some portion of its tissues; and may include encysted, fatty or fibrous tumors; or, _second_, they may be found in the interior, springing from the mucous membrane, and resembling polypi in their form and structure. They are sometimes granular or cauliflower-like in appearance, and vary in size from a pea to a hazel-nut.
