Cordectomy is the surgical removal of a cord. It usually refers to removal of one or both vocal cords, often for the purpose of treating laryngeal cancer. [1] [2] The word is derived from the Greek, combining chorde and ektome meaning excision. It can be carried out by traditional surgical techniques or, increasingly, by carbon dioxide laser. [3]
This modified procedure involves a judicious excision of 3.5–4 mm C-shaped wedge in posterior vocal cord from the open edge of the membranous cord using carbon dioxide laser. Excision is made anteriorly to the vocal process, continuing 4 mm laterally on to the ventricular band without exposing the cartilage.
Laryngeal cancer may spread by: direct extension to adjacent structures, metastasis to regional cervical lymph nodes, or via the blood stream. The most common site of distant metastases is the lung. Laryngeal cancer occurred in 177,000 people in 2018, and resulted in 94,800 deaths (an increase from 76,000 deaths in 1990).
Anatomical parts seen during laryngoscopy. Direct laryngoscopy is carried out (usually) with the patient lying on their back; the laryngoscope is inserted into the mouth on the right side and flipped to the left to trap and move the tongue out of the line of sight, and, depending on the type of blade used, inserted either anterior or posterior to the epiglottis and then lifted with an upwards ...
Flexible Endoscopic Evaluation of Swallowing with Sensory Testing (FEESST), or laryngopharyngeal sensory testing, is a technique used to directly examine motor and sensory functions of swallowing so that proper treatment can be given to patients with swallowing difficulties to decrease their risk of aspiration (food and liquids going into the lungs instead of the stomach) and choking.
straight mirror for indirect laryngoscopy (seeing the larynx); structure seen are the base of tongue, vallecula, glossoepiglottic fold, epiglottis, pharyngo-epiglottic folds, aryepiglottic folds, epiglottis, interarytenoid region, pyriform sinus, inlet of larynx, supraglottic region, ventricular bands, vocal cord, subglottis and few rings of ...
This contrasts with traditional laryngeal speech, which involves oscillation of the vocal folds. In esophageal speech, pressurized air is injected into the upper esophagus and then released in a controlled manner to create the airstream necessary for speech. Esophageal speech is a learned skill that requires speech training and much practice.
Vocal cord nodules are bilaterally symmetrical benign white masses that form at the midpoint of the vocal folds. [1] Although diagnosis involves a physical examination of the head and neck , as well as perceptual voice measures, visualization of the vocal nodules via laryngeal endoscopy remains the primary diagnostic method.
