What is a cadaveric position?
The intermedian position of the vocal cords, forming a slight excavation, was called clinically as the cadaveric position of the vocal cords.
What is Semon’s law?
In 1881, Semon1 formulated his well known law stating that in. incomplete or partial recurrent laryngeal nerve paralysis there is. an isolated paralysis of the abductor function of the glottis. ‘ l’lus. proclivity to disease of the abductor over the adductor muscles.

What happens when the glottis is closed?
The narrowed glottis that Abercrombie refers to is meant to account for ‘whisper,’ (Film clip 3) which is noisier than ‘breath,’ and the closed glottis refers to the state known as a ‘glottal stop,’ (Film clip 4) when the passage is closed, allowing no air (either breath or voiced flow) to pass through.
What happens when your vocal cords are paralyzed?
Vocal cord paralysis happens when you can’t control the muscles that move your vocal cords. If your vocal cord doesn’t close, it leaves a space for food, fluids and saliva (spit) to enter into your windpipe and lungs. Problems with breathing, swallowing and speaking can result.

What is Paramedian position of a vocal cord?
The abnormal movement can be characterized as being paretic, meaning some movement is present, albeit reduced or paralyzed, with complete cessation of vocal fold movement. If a true vocal fold is paralyzed, it can be described as being paralyzed in a midline, paramedian, or lateral position.
What is askew position of glottis?
Askew position of glottis (anterior commissure rotated to healthy side). Shortening of vocal cord with loss of tension (wavy appearance of paralyzed vocal cord). Flapping of paralyzed vocal cord (sags down during inspiration and bulges up during expiration).
What is Microlaryngeal surgery?
Microlaryngeal surgery, also known as phonomicrosurgery, is a workhorse procedure that deals with a variety of laryngeal conditions, including benign vocal fold lesions, vocal fold paralysis, vocal fold scarring, vocal fold leukoplakia or cancer, and airway stenosis.
What causes sulcus Vocalis?
Causes of Vocal Fold Scarring Vocal fold scar and sulcus vocalis may form due to unhealthy or inefficient voice use, intubation related trauma (from a breathing tube), history of laryngeal (voice box) infection, or radiation therapy. Some cases of sulcus vocalis may be congenital (present at birth).
What is the position of glottis?
The glottis is the opening between the vocal folds in the larynx that is generally thought of as the primary valve between the lungs and the mouth; the states of the glottis are the positions generally considered to characterize the different possible shapes of this opening.
What is the difference between glottis and epiglottis?
Glottis vs Epiglottis Glottis opens into the windpipe and is responsible for the production of sound. While the epiglottis is a cartilaginous flap on top of the glottis that prevents the food from entering into the larynx. The main difference between glottis and epiglottis is their function and the structure.
What happens to your voice if you don’t talk for a long time?
In terms of long-term damage, you’d have to be not speaking for a very, very long time. Now, we know that the voice goes through changes as we get older, when the voice can actually get weaker, just like other parts of our body get weaker as we get older. And we have to make sure they stay – you know, it stays strong.
What is vocal fold Hypomobility?
Hypomobility is defined as a decreased mobility of the vocal fold in its adductory, abductory, or tensor functions, as evidenced by sluggish adduction or abduction, vocal fold bowing, limited vocal fold lengthening with voluntary increase in pitch, or axial rotation of the larynx.
What is vocal fold immobility?
When one vocal cord does not move properly (unilateral vocal cord immobility), it can lead to a weak, breathy voice, inability to raise the volume of the voice and the sensation of running out of air while speaking. Problems with swallowing and a weak cough are common as well.
What is RLN palsy?
Recurrent laryngeal nerve (RLN) palsy occurs in 5% to 11% of patients following thyroidectomy and is the second most common early complication. Unilateral RLN injury produces abductor vocal cord paralysis. The affected vocal cord assumes a paramedian position. Patients often present with postoperative hoarse voice.
What is Dlscopy?
A direct laryngoscopy allows visualization of the larynx. It is used during general anesthesia, surgical procedures around the larynx, and resuscitation. This tool is useful in multiple hospital settings, from the emergency department to the intensive care unit and the operating room.
Why is a Microlaryngoscopy done?
Microlaryngoscopy is a surgical technique used in the evaluation and removal of various lesions of the vocal folds, including (but not limited to): cancer, cysts, papilloma, polyps, and Reinke’s edema. A surgeon looks through through the operating microscope and uses fine microinstruments to remove a vocal fold polyp.
What is Pseudosulcus?
Pseudosulcus is infraglottic laryngeal edema that is thought to be secondary to LPR. All patients were evaluated with dual-channel pH probe 24-hour monitoring to evaluate for the presence of laryngopharyngeal reflux.
Can sulcus vocalis be cured?
The surgical procedure with supplementary injection laryngoplasty of the vocal folds is a good treatment option for pathological sulcus vocalis. The post-treatment self-assessment indicates the significant improvement in VHI, just as perceptual–acoustic evaluation of voice does.
What is Carina?
A ridge at the base of the trachea (windpipe) that separates the openings of the right and left main bronchi (the large air passages that lead from the trachea to the lungs). Also called tracheal carina.
What is gullet and glottis?
Gullet also called as oesophagus is long tubular structure through which food passes from mouth to stomach. Glottis is the opening of the wind pipe (trachea). It is covered by a flap of skin called epiglottis that prevents entry of food into wind pipe.
What is the difference between epiglottis and uvula?
The uvula is a soft tissue structure that is wedge-shaped while the epiglottis is a cartilaginous flap that is leaf-shaped [3]. While the uvula is located at the base of the tongue, the epiglottis on the other hand is situated on the cranial portion of the laryngeal prosthesis.
Can mute people whisper?
If you listen to someone whispering you ll notice that sounds like s are much louder than the other sounds because they aren t affected by the open vocal folds. So, if someone has trouble talking because they have damage to the vocal folds in their larynx, they should still be able to whisper.
What is Pharyngectomy?
(FAYR-in-JEK-toh-mee) Surgery to remove all or part of the pharynx (throat). The pharynx is the hollow tube inside the neck that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes to the stomach). A pharyngectomy may be done to treat certain types of throat cancer.
