The larynx can be shaped by the genes we inherit. This section examines four structural disorders that arise from within: a groove in the vocal cord muscle that was never fully formed, a cyst that fills silently until it threatens the airway, a waxy protein depositing in the supraglottis, and an autoimmune attack on cartilage that does not discriminate.
◆ Sulcus Vocalis
Pandit has been called “ma’am” on the phone his whole life. The louder he speaks, the higher his pitch climbs. A groove along both vocal cords tells the story: the muscle inside them never fully developed.
◆ Saccular Cyst
A retention cyst arising from the laryngeal saccule can quietly enlarge until it distorts the supraglottic anatomy — or, in a newborn, closes the airway entirely.
◆ Amyloid
Pale, waxy deposits accumulate silently in the supraglottis. Surgery removes them, but amyloid has a way of returning.
◆ Relapsing Polychondritis
An autoimmune attack on cartilage that does not discriminate. As the laryngeal and tracheal framework softens, the airway narrows and the voice fails.
