A multimedia encyclopedia containing articles, photo galleries, and videos ranging from A—Z for topics concerning laryngology.

Disorders

Fasciculations

Fasciculations are spontaneous, involuntary contractions of motor units, producing brief muscle twitches beneath the skin or mucosal surface.

Airway disorders

PAPZIMEOS (Zopapogene Imadenovec) for Recurrent Respiratory Papillomatosis (Laryngeal Papillomas)

Papzimeos (zopapogene imadenovec) is a targeted immunotherapy developed for the treatment of RRP, caused by the human papillomavirus (HPV).

Anatomy & Physiology

Arytenoid Sequestrum

In the larynx, a sequestrum may occur due to radionecrosis after treatment for cancer, chronic intubation, or infection.

Anatomy & Physiology

Vibratory Blur

When someone phonates, the vocal cords vibrate extremely fast, creating a vibratory blur to the naked eye.

As the vocal cords begin to approximate to produce voice, the bulge begins to contact the right cord.

Disorders

Paraglottic Mass and Birt–Hogg–Dubé (BHD) Syndrome

Birt–Hogg–Dubé is an autosomal dominant genetic disorder caused by pathogenic variants in the FLCN tumor-suppressor gene on 17p11.2.

On the left, the image is above the top of the arytenoid cartilage. On the right, the calcification continues into the tumor, which also extends anteriorly, beyond the calcification.

Cartilaginous

Chondrosarcoma of the arytenoid cartilage is a rare malignant neoplasm. Fewer than 10 % of all laryngeal chondrosarcomas arise from the arytenoid rather than the cricoid (most common) or thyroid cartilages. Almost all chondrosarcomas are low grade, and therefore slow-growing.

Airway disorders

Supraglottic Stenosis

Supraglottic stenosis is a pathologic narrowing of the airway above the level of the true vocal folds, involving the epiglottis, aryepiglottic folds, false vocal cords, or adjacent pharynx and epiglottis. Common Etiologies Include: Radiation therapy (most frequent acquired cause in

Squeezed Vocal Cords of Tonic Variant Adductory SD

Disorders

Stage Whisper Variant of Adductory Spasmodic Dysphonia (AD-SD)

The common phenomenology of adductory spasmodic dysphonia (AD-SD) includes both strain and phonatory arrests. Strain produces a gravelly, “squeezed and strangled” voice quality, while phonatory arrests cause the voice to “catch” or “grab,” resulting in syllable or word dropouts. A

Botox

EMG-Guided Injection of Botulinum Toxin for R-CPD

EMG-guided injection of botox for R-CPD is done through the neck while the patient sits upright in an office examining chair.
