| laryngeal aperture | The aperture between the pharynx and larynx, bounded by the superior edges of the epiglottis (anteriorly), the aryepiglottic folds (laterally), and the mucosa between the arytenoids (posteriorly). Synonym: aditus laryngis, laryngeal aperture. (05 Mar 2000) |

| laryngeal atresia | Congenital failure of the laryngeal opening to develop, resulting in partial or total obstruction at or just above or below the glottis. (05 Mar 2000) |
| laryngeal bursa | The bursa located between the junction of the laminae of the thyroid cartilage and the skin. Synonym: bursa subcutanea prominentiae laryngeae, laryngeal bursa. (05 Mar 2000) |
| laryngeal cancer | A malignant (cancerous) tumour of the larynx. Presentation includes a progressively hoarse voice, difficulty swallowing and weight loss. Risk factors include smoking and heavy alcohol consumption. (27 Sep 1997) |
| laryngeal cartilages | The nine cartilages of the larynx, including the cricoid, thyroid and epiglottic, and two each of arytenoid, corniculate and cuneiform. (12 Dec 1998) |
| laryngeal chorea | A spasmodic tic involving the muscles, resulting in an explosive manner of talking as in spasmotic dysphonia. (05 Mar 2000) |
| laryngeal crisis | An attack of paralysis of the abductor, or spasm of the adductor, muscles of the larynx with dyspnea and noisy respiration, occurring in tabetic neurosyphilis. (05 Mar 2000) |
| laryngeal diphtheria | Diphtheria affecting the larynx, usually with asphyxiation due to obstruction of the airway by the membrane that forms, with fatal outcome. Synonym: laryngotracheal diphtheria. (05 Mar 2000) |
| laryngeal diseases | Disorders of the larynx, general or unspecified. (12 Dec 1998) |
| laryngeal epilepsy | A form of reflex epilepsy precipitated by coughing. (05 Mar 2000) |
| laryngeal glands | A large number of mixed glands in the mucous membrane of the larynx; they are called, according to their situation, anterior, middle, and posterior. Synonym: glandulae laryngeae, laryngeal glands. (05 Mar 2000) |
| laryngeal granuloma | A polypoid granulomatous projection of granulomatous tissue into the lumen of the larynx, commonly following a traumatic tracheal intubation. (05 Mar 2000) |
| laryngeal lymphatic follicles | Small follicles located on the posterior aspect of the epiglottis and in the ventricle of the larynx. Synonym: folliculi lymphatici laryngei. (05 Mar 2000) |
| laryngeal mask | A tubular oropharyngeal airway with an inflatable rim at the distal end that when inflated creates an airtight seal immediately above the larynx. (05 Mar 2000) |
| laryngeal masks | A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anaesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or oesophagus. It is used in place of a facemask in routine anaesthesia. The advantages over standard mask anaesthesia are better airway control, minimal anaesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
