The vestibular fold (ventricular fold, superior or false vocal cord) is one of two thick folds of mucous membrane, each enclosing a narrow band of fibrous tissue, the vestibular ligament, which is attached in front to the angle of the thyroid cartilage immediately below the attachment of the epiglottis, and behind to the antero-lateral surface of the arytenoid cartilage, a short distance above ...
The male's vocal folds are between 1.75 cm and 2.5 cm (approx 0.75" to 1.0") in length, [3] while females' vocal folds are between 1.25 cm and 1.75 cm (approx 0.5" to 0.75") in length. The vocal folds of children are much shorter than those of adult males and females.
Type 1 thyroplasty – Medialization of the vocal folds (most common surgery for unilateral vocal cord paralysis). Type 2 thyroplasty – Lateralization of the vocal folds (in case of airway insufficiency after Laryngeal trauma). Type 3 thyroplasty – Shortening of the vocal folds (done to lower the vocal pitch).
Instead, an alternative procedure, Vocal Fold Shortening and Retrodisplacement of the Anterior Commissure (VFSRAC), a type of modified Wendler Glottoplasty, is generally recommended as it preserves the ability to sing. [21] Vocal Fold Muscle Reduction, a standalone laser tuning procedure, can also be considered for professional voice users as well.
Vocal rest is also recommended after surgery to removal of vocal fold lesions, such as vocal fold cysts. [2] The purpose of vocal rest is to hasten recovery time. It is believed that vocal rest, along with rehydration, will significantly decrease recovery time after a cold. [3]
The vocal cords and the rima glottidis are together designated as the glottis. The laryngeal cavity above the vestibular folds is called the vestibule. The very middle portion of the cavity between the vestibular folds and the vocal cords is the ventricle of the larynx, or laryngeal ventricle.
Each of these techniques results in medialization of the paralyzed vocal cord. However, arytenoid adduction is preferred in cases where there is a large posterior glottal gap or vertical misalignment between the vocal folds. Arytenoid adduction is often performed at the same time as a medialization thyroplasty.
Laryngology is a branch of medicine that deals with disorders, diseases and injuries of the larynx, colloquially known as the voice box.Laryngologists treat disorders of the larynx, including diseases that affects the voice, swallowing, or upper airway.
