What is cricothyroid approximation?
Cricothyroid approximation was one of the most common surgeries of the past 20 years used to change the relaxed pitch of the voice. Your original voice in falsetto will sound the same after surgery as before surgery, so you can test out what your voice will sound like by speaking in falsetto.
Which muscle brings the vocal folds into approximation?
Thyroarytenoid muscle: extends from angle of the thyroid cartilage to arytenoid cartilage. They pull the arytenoid anteriorly, relaxing the vocal folds. They also approximate the vocal folds.
What is reduction Glottoplasty?
Laser reduction glottoplasty is a relatively new surgical procedure for voice feminization on transgender women. This study aims to determine long-term voice results of glottoplasty on transwomen.
What does the Cricothyroid muscle do?
The cricothyroid muscle pulls the arch of the cricoid cartilage upwards. In doing so, it pulls the arytenoid cartilages backwards, making the vocal folds longer and tighter.
Where is the Cricothyroid joint located?
larynx
The cricoarytenoid and cricothyroid joints are the two sets of paired joints located in the larynx. These synovial joints act simultaneously to modulate the movements of the vocal cords.
How does voice feminization work?
Your speech-language pathologist will work with you to help prevent vocal misuse and vocal damage. Surgeries for voice feminization focus on raising habitual speaking pitch by reducing the ability to produce a low-pitched voice. This means that surgery will reduce the overall pitch range of your voice.
What is Cricothyroid ligament?
The cricothyroid ligament connects the cricoid and thyroid cartilage. The cricothyroid membranes link the cricoid, thyroid, and arytenoid cartilage. Articulation (joint movement) is performed by the thyroid and cricoid cartilage with the help of synovial joints, which are moved by the cricothyroid ligament.
What is laser reduction Glottoplasty?
Abstract. Objectives: Laser reduction glottoplasty is a relatively new surgical procedure for voice feminization on transgender women. This study aims to determine long-term voice results of glottoplasty on transwomen. Methods: Nonrandomized, retrospective, cohort.
What is Medialization Thyroplasty?
Medialisation Thyroplasty (MT) is a procedure in which one of both of the vocal folds is/are augmented by placing an implant into the vocal fold. If both vocal folds are augmented this is called a bilateral medialisation thyroplasty.
What happens if cricothyroid muscle is damaged?
Damage to this nerve results in an inability to attain the high registers of voice and singing, impaired pitch regulation, and vocal weakness or fatigue, although a normal speaking voice is often present.
How big is the cricothyroid membrane?
The size of the cricothyroid membrane in the western population is reported as 7.5 mm–10.5 mm in female cadavers and 10.0 mm–13.0 mm in male cadavers 4-6. A study examining the south Indian population found the cricothyroid membrane to be much smaller, at 3.0 mm–8.4 mm in female and 3.0 mm–10.0 mm in male cadavers 7.
