Voice therapy consists of techniques and procedures that target vocal parameters, such as vocal fold closure, pitch, volume, and quality. This therapy is provided by speech-language pathologists and is primarily used to aid in the management of voice disorders, [1] or for altering the overall quality of voice, as in the case of transgender voice therapy.
Further treatment or revision surgery might be needed for some patients with serious unresolved sound hoarseness after extended periods of recovery. [16] If the vocal cords heal with asymmetrical tension, laser treatment is generally required to correct the defect.
Thyroplasty is a phonosurgical technique designed to improve the voice by altering the thyroid cartilage of the larynx (the voice box), which houses the vocal cords in order to change the position or the length of the vocal cords.
Stroboscopy allows the visualization of vocal cord movement, which vibrate too quickly for human eye to perceive. [15] When assessing the vocal cords, the most common finding in MTD is a posterior glottic gap. [2] Other findings include increased movement of the vocal folds towards one another, and changes in the angles of the vocal fold ...
The site for the cordotomy is determined at the preoperative examination. If any one of the vocal fold seems to have a slightest degree of motion, then cordotomy is performed on the other one. Using CO 2 laser with a spot size of 0.2 mm and power of 3-5 Watts, a cordotomy is performed 1-2mm anteriorly to the vocal process. This is then carried ...
The purpose of the puncture is to restore a person’s ability to speak after the vocal cords have been removed. This involves creation of a fistula between the trachea and the esophagus, puncturing the short segment of tissue or “common wall” that typically separates these two structures. A voice prosthesis is inserted into this puncture.
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.
The paralyzed vocal cord may rest close to or far from the midline. An extremely laterally positioned vocal cord can result in a large posterior glottal gap - an opening between the two vocal cords even when the functioning vocal cord is fully medialized. Vocal cord injection is ineffective for closing a large glottal gap. [6]
