Laryngocele

A disorder in which the laryngeal saccule is inflated and becomes abnormally enlarged. A common symptom of a laryngocele is hoarseness. How it develops: The laryngeal saccule, or laryngeal appendix, is a very small blind sac—a dead-end corridor, so to speak—which is located just above the vocal cords, one on each side, and is lined […]

Glottic Sulcus

A degenerative lesion consisting of the empty “pocket” of what was formerly a cyst under the mucosa of the vocal cord. The lips of a glottic sulcus may be seen faintly during laryngeal stroboscopy. Or, vibratory characteristics may suggest this lesion. A glottic sulcus may be overlooked unless one is familiar with this entity. To […]

Stenosis

Abnormal narrowing of a passageway in the body. At our practice, stenosis typically refers to narrowing in the breathing passage, such as for narrowing in the glottic, subglottic, or tracheal areas. Stenosis in the airway can be the result of prolonged endotracheal intubation, external trauma such as gunshot wound, crush injury, or tracheotomy, an inflammatory […]

Segmental Vibration

In the normal larynx, segmental vibration occurs when both chest and falsetto (head) registers are produced by vibration of the anterior 2/3 of the vocal cords. The posterior 1/3 is “inhabited” by the arytenoid cartilage and does not vibrate. In certain pathological circumstances such as displayed in the photo sequences below, only a small part […]

SLAD-R

SLAD-R (Selective laryngeal adductor denervation-reinnervation). This procedure was introduced by Dr. Gerald Berke of UCLA in the late 1990’s. It is a surgical option for adductory spasmodic dysphonia. The concept is to sever the anterior branch of the recurrent laryngeal nerve. This denervates the spasming laryngeal adductors (particularly thyroarytenoid and lateral cricoarytenoid muscles). The squeezed, strained […]

Translucent Polyp

Some polyps are covered by mucosa that is opaque. Some are filled with blood (hemorrhagic polyp). On the other hand, some have a thin and delicate mucosa, and a watery content that is not transparent, yet transmits some light. Unlike a blister, which they could be construed as resembling, and which typically resolves itself, most […]

Phonatory Gap

Phonatory gap occurs when the vocal cords fail to close during phonation. A phonatory gap may be seen in patients who have muscle tension dysphonia, vocal cord paresis or paralysis, loss of tissue, or vocal cord flaccidity. In addition, however, a phonatory gap occasionally occurs in patients who have none of the above conditions. In […]

Pharyngeal Paralysis

The pharynx (loosely “throat”) has a “foodway” function to convey food and liquid from the mouth to the esophagus. It also serves as part of the “airway,” also from mouth into the Larynx and trachea. These foodway/airway functions are kept separate so food and liquid do not enter the airway towards the lungs. At the […]

Croup

Also known as laryngotracheitis or laryngotracheobronchitis, croup 1 is a primarily pediatric viral disease affecting the larynx and trachea. Though it may resemble a simple cold at first, the infection causes a loud barking cough and stridor (unusual, high-pitched breathing noises indicating partial airway obstruction). The majority of cases are caused by parainfluenza viruses (types […]
