The voice and yogurt PartII: Is yogurt is good for the high register?

This post is a continuation of Part 1.
As previously stated, yogurt can strengthen the mucosa because it is a non pathogenic bacteria which has is high source of Vitamin A and B2.
The vocal cord’s mucosa is important in successfully producing a falsetto register and also assists in the relaxation of the the vocal muscles. Production of the falsetto, vibrates only the ligamentous edges of the vocal folds while leaving each fold’s body relatively relaxed. The folds are covered on the surface by mucosa, which is supported deeper down underneath by the innermost fibers of the thyroartenoid muscle.
How much yogurt should a person eat before showing signs of improvement to the mucosa?
Though each persons weight and body type does play an important factor in the intake, for and average person I recommend 7oz per day. Roughly, 1 serving of yogurt.
You should keep eating yogurt every day,
Give it a try!
Note1: I got a lot of requests asking, “To document and perform tests, through a yogurt study.” Investigating the issue would be a challenge because the mucosa is very small and can only been seen telescopically. How would I test and observe the changes of the mucosa of vocal chords?
Examine a selected group, daily for 6 months
Examinee A:Eat 7oz yogurt (okay to spit serving at different meal times)
Examinee B:Eat 3/4oz
Examinee C:Eat no yogurt, or dairy products
—Observation Procedure—
(1)Quality of voice (reviewed by self and others)
(2)Visual examination using an optical fiber scope
(3)Snapshot of cross-section by MRI (Magnetic Resonance Imaging) which can  measure the thickness of the vocal mucosa
(4)Measure elasticity, using the method of palpation.
Note2:It would be interesting if several different brands of the most commonly purchased yogurt were tested, as to make it more convenient for consumers.


The voice and yogurt : vocal cord atrophy

There are many positive effects of yogurt for the body, such as beauty, prevention of influenza and even hay fever…  One of my clients recently reported that yogurt had helped their vocal cord atrophy.
When I worked at a clinic, the same client came in to see our otolaryngologist for a vocal cord atrophy diagnosis.
I saw him because he did not need surgery.I visually inspected, performed palpation, did an image inspection and ordered a blood flow ultrasonogram in order to investigate the status of larynx.
As a result, I discovered the space of the thyrohyoid bones were narrower and displayed poor blood flow on the superior laryngeal artery. I stretched the vertical axis of the larynx muscles by tugging, making the muscles flaccid by exclusive low-frequency waves focusing on the extrinsic laryngeal muscles and then spreading out the thyrohyoid bones by way of massage.
I saw the effects instantly on the muscles after I applied my techniques and healing methods, but his hoarse voice was not effected.
I then asked him, “Do you like yogurt? Yogurt is a non pathogenic bacteria that is good for the body and strengthens mucosa. So I recommend adding it to your daily food intake to treat your hoarse voice.”
One year later, the client informed me, he had been including yogurt in his diet and that his hoarse voice had in fact recovered. He stated,” I eat yogurt everyday now and agree it helps the voice.Thank you so much!” I said, “Yes, this is the power of yogurt!”

I’ve have treated so many patients who have been diagnosed with vocal chord atrophy or sulcus vocalis, and approximately 80% of them have recovered.
Vocal cord atrophy is commonly believed not to heal naturally by many in the field of medicine. As stated above 80% of the clients who applied my healing techniques did in fact recover from vocal chord atrophy.
Why did I recommend him yogurt?
Because yogurt is a good source of Vitamin A and B2, it strengthens the  mucosa.The vocal chord is composed of 2 layers,which are the mucosa and muscle.(Actually 5 layers if further classified)
Although it is still not known what causes vocal chord atrophy.
If the vocal chord atrophies, the glottis opens, the breath leaks and creates a hoarse voice. This does not mean you lose your voice, the voice is just constantly hoarse and hard to hear.
It’s not good for holding long conversations, and it also makes it hard to vocalize in high registers.
Yogurt truly does affect the mucosa, that’s why. But, if the tissue is reconstructed, the hoarse voice will and can recover.
In this case, I was not sure whether adding the yogurt to the daily diet or my applied massage techniques healed the vocal chord atrophy, so I do recommend trying both.

Note:This diagram features vocal chord atrophy and poor blood flow in the superior laryngeal artery. Furthermore, regarding the start of symptoms, I think that most of patients that suffer LDP(Larynx Deep Position) are more prone to suffering from vocal chord atrophy.
I’ve sketched this diagram about vocal chord atrophy.
Please note the edges of the vocal chords.

Loss of voice, due to a cold or singing too much

So you have lost your voice due to overuse through singing or from a severe cough during a cold – You can recover and take treatment in the otological hospital or just rest your throat. Your throat is then better, and almost back to normal, but for some reason you cannot sing or speak like before.
Some people cannot recover completely when they lose their voice. After the voice returns it sounds different than before, it is harder to let out a high pitch, or still sounds hoarse. Why?
It is because the muscles have been strained and cannot go back to their original state before the damage from overuse or severe coughing was done. This issue is consistent with the intrinsic laryngeal muscle, including the vocal chords and the extrinsic laryngeal muscle used for phonation. The intrinsic laryngeal muscles are responsible for controlling sound production. Whereas the extrinsic laryngeal muscles support and position the larynx within the trachea.
If you have lost your voice due to a cold or singing too much, you do not only do damage to the intrinsic laryngeal muscle, but also the extrinsic laryngeal muscle.
I’ll show you an example of what to expect from the cases I have seen:

In the case of sing or cough too long
◆People who do not have LDP:
●This issue can be recognized visually by observing a fine scratch that’s located on the membrane of the posterior cricoarytenoid muscle and the lateral cricoarytenoid muscle. A metabolic disturbance of the cricothyroid muscle and also, mild inflammation (myofascitis or laryngitis).

◆People who have LDP:
●In addition to the above symptoms, you would observe another fine scratch on the membrane of the omohyoid muscle, the sternohyoid muscle and the thyrohyoid muscle.

In the case of a loud cough or voice
◆People who do not have LDP:
●The fascia of the stylopharyngeus muscle and the stylohyoid muscle ruptures
●The laryngx twists due to an imbalance between the left and right muscles.

◆People who have LDP:
●In addition to the above symptoms, damage of the pharyngeal constrictors can be observed (this symptom is caused by the outer edge of the thyroid cartilage and the front cervical spine applying pressure to the pharyngeal constrictors)
●The fascia of the omohyoid muscle,the sternohyoid muscle and the thyrohyoid muscle ruptures
●In rare cases of deformation, depending on the damage severity, the stylohyoid ligament and cricoid cartilage can tear.

The red circle is an example of a scar at the bottom of the posterior cricoarytenoid muscle.

Singing comfortably is different than a ”weak” or ”soft” voice

A student was instructed by his vocal trainer to, ”Be more effortless when singing a song.” Consequently, his voice got quieter when he was supposed to sing louder and more powerful. Relaxation and being comfortable play a major role in the delivery of the sound produced.
“Effortless” was referring to, that you should focus on only relaxing unnecessary muscles for phonation, not the whole laryngeal muscle. “Singing louder and more powerful” is different than a “weak voice” or “small voice.”
The average person has approximately 630 muscles (mainly voluntary muscles) in the body. Most of the muscles can detect the hardness and movements when produced. The muscles of the throat cannot detect the hardness or movements.
For instance,when you say “pa” or “i”, do you know to what degree of strength you are using in your muscle, exactly?
–  or when you vocalize tone “C” or “A”, do you know to what degree of strength you are using with those muscles?
No, because, it is impossible to determine.
The thought is planted and movements are followed through by the brain, but simultaneous awareness of the amount of strength being issued to each specific muscle group at the time of the movement is something that has to be learned through practicing, focusing and vocal training.
Therefore, if you act too loose or comfortable while singing … for example,  completely relaxed, all the muscles relating to phonation will get flaccid, and it is harder to vocalize and/or control the movements.
Let’s compare the vocal movement to a body movement such as jumping. If you want to jump high, you have to bend the knee and use the muscles in the thigh and leg region. You cannot jump without stretching out your legs.
So, if your knee is hardened or the muscles are tense, you cannot jump. That is why, you have to soften the movement around the knee to jump high.This does not mean that the muscle is relaxed in the thigh and leg region.
Which muscle should be relaxed and focused for phonation?
First, relax the pharyngeal constrictors, (especially the superior, middle and annular part) then the stylopharyngeus muscle, the stylohyoid muscle, the digastric and the omohyoid muscle. Simultaneouly, and constantly move the cricothyroid muscle, the posterior cricoarytenoid muscle and the lateral cricoarytenoid muscles. The former relates to the environment of the movement and the latter relates to the pure natural movements such as expanding the vocal chords (for high pitch) or closing vocal chords (glottic closure).
It becomes possible to make your voice more loud and rich if you can control this, and utilize this technique correctly.
I would like you to practice and learn to relax your throat properly, which will in turn make your voice better.

Mixed voice! The solution of a mystery…

When comparing vocal chords to a music instrumental, the shared goal is to make sound and control/change the pitch of the sound .
The important thing is that the sound is just a fundamental tone, not producing an alluring voice or beautiful high notes.
For example, If you only pick the strings of a a guitar without the body, it would sound so small and poor. But, you can change the small/poor sound by using the hollow space of the body to be able to create an echo and produce an overtone of sound.
Take that concept, and apply it to the human voice, this is the resonance chamber. And it is composed of :                                                                       1.laryngeal ventricle 2.piriform recess 3.pharyngeal cavity 4.oral cavity 5.nasal cavity
There are some people who think that the chest and belly are also resonance chambers but that is not a fact. The reason is, because the voice expels the sound and the sound is created through a vibration of air.
The air (exhaled) is made by picking the vocal chord. Never get in chest or the abdominal cavity(of course not!) Again, this is only the path for the air inhaled and exhaled.
If you feel a resonance in chest,abdominal, head,shoulder,knee or elbow, I think that’s vibration but not resonance.
Previously,some vocal coach believed that the sound come from knee of elbow.
It’s probably possible to feel that the organ which is near by the vocal tract vibrates but I wonder whether knee and elbow also resonate or not.
Let talk more about the structure of vocal chord.
I think what I can get some idea about good voice and singing.
I talked about the cross of the vocal chords before: click here link
If I sketch out the role of good voice or singing to require for vocal chord as fundamental tone,that is the natural voice ,falsetto and mix voice.
It does not include tone color such as beautiful voice because the tone is made in resonance chambers.
By the way, what is the natural voice ,falsetto and mix voice?
I tested before,and I asked young great mimic who copied a bunch of voices which were chosen by me, and ask them(who is singer,voice actor,actor,people have no interest in voice)to listen his voice.
Which one do you think natural ,falsetto or mix voice?
As a result, surprisingly every answer was different…
Especially about sensitive mix voice, elite singer even could not figure out which is exact one
such as ”This voice is mix voice but close to natural voice” ”no,close to falsetto” ”no,exact falsetto” ,i.e….
Therefore, there is no exact definition.
How natural ,falsetto and mix voice is generated?
If you know this correctly,you can understand why every voice sounded different for everyone.
I mentioned that the natural voice is made by vibrating the vocal mucosa and muscle, falsetto is made by only vibrating vocal mucosa, and mix voice is made by changing the hardness of vocal muscle and the vibration rate so far. This is rough explanation and let me explain more detail.
It’s easy to know what happens on the natural voice,and the muscle is weighty, and if the whole muscle can vibrate correctly, it makes the clear voice.
In the case of falsetto voice, the part of vocal mucosa outside the vocal ligament only vibrates.
This means that’s stratified squamous non-keratinizing epithelium and Reinke’s space.
Be aware of two things about this.
How does the muscle move during singing falsetto?
I’ve looked into the status of vocal chord through the fiber scope before when producing the natural,falsetto,mix,edge,whistle or death voice and so on.
In the case of falsetto voice,I did not see any vibration on vocal muscle,which is far from glottis because the muscle is rigid.
The vocal muscle is the skeletal muscle but not visceral muscle, which moves involuntarily.
The skeletal muscle has some features. It shrinks and gets rigid,and this mechanism makes the falsetto voice.
I know that someone cannot come out the falsetto due to the rigid vocal muscle by constitution.
Next one is that the vibration changes depends on the status of loose connective tissue in Reinke’s space.
There is collagen fiber relating to the hyaluronan and the collagen in Reinke’s space.
The loose connective tissue bears the nonkeratinized stratified squamous epithlium which has a lot of fluid element. That’s why,the vibration is changed by gel.
If this fluid becomes less,the vocal fold contracts, hard to make falsetto or cases the vocal cord atrophy in the worst case.
The peoples who had the vocal cord atrophy have improved partially by hyaluronic acid injection before.
The last is talking about mix voice!
The point is what you give the vocal muscle flexibility and power,moisturize the vocal muscle if I roughly talk about how to control the hardness of vocal muscle and moisturize the vocal fold,and it’s important that is the vocal ligament and the elastic cone,ligament generally bonds between bones.
The vocal ligament bonds the processus vocalis cartilaginis arytenoidei and anterior commissure of thyroid cartilage,this does not make the arthroplasty for indented usage. The larynx is really unclear part in human body.
The vocal ligament also has a big roll with the arytenoid cartilage rotating and sliding.
The vocal ligament is required to provide plenty of support the vocal muscle for getting move better,and there is the elastic cone between the vocal ligament and the arch of cricoid cartilage.
This means that the elastic cone also supports the vocal ligament.
If the vocal ligament and the elastic cone are not steady,that degrades the motion performance of vocal muscle.
Furthermore, it would be a waste not to use the elastic cone, this connects to vocal fold closely.
If you could make it suitable vibration,you can make a wider sound.
After I tried using the artificial arytenoid cartilage and cricoid cartilage which made by paper clay, I’ve figured out the relation between the movement of the vocal muscle,the vocal ligament and the elastic cone.
Although, this is still during the experiment and hypothesis, I’m willing to continue investigating this.
The people is good at using mix voice who sounds really good singing.
Note:The hardness of vocal muscle is changed by muscular excitation and relaxation, expansion and contraction by moving the arytenoid cartilage and blood pressure change(not disease),and the above 3 points.

LDP causes hoarseness

LDP stands for “Larynx Deep Positioning.” That is when the muscles of the throat stiffen, and the hyoid bone, the thyroid cartilage and the cricoid cartilage move towards the cervical spine a few millimeters.

The thyroid lies deep in the throat, the arytenoid cartilage moves toward the cervical vertebrae and finally, the arytenoid cartilage is forcibly rotated by pressuring the corniculate cartilage, and the back of vocal chord slightly opens.
Surprisingly, the voice is not significantly influenced by this because the arytenoid cartilage is located behind the vocal process.
Furthermore, if you go to see the ear, nose and throat doctor, known as an Otolaryngolist, it’s hard to visually see the symptoms through the laryngo fiber scope.This is not a disease, it is a condition.
If you do not have an ear for music, you probably would not immediately recognize a hoarse, mildly cracking voice.
This does not matter to Karaoke hobbyists or normal conversationalists but it is a problem for career singers.
If you care about this issue, I’d like you to check the position of your larynx.
This worry is going to be wiped away – if you can detect and fix this LDP problem.
The photo of model A:
The finger is pointing the part of the cartilago corniculata, it’s pressured by the front of cervical spine.
The photo of model B:
The finger is pointing to the back of the vocal chord, and this part is opened forcibly by the rolling arytenoid cartilage.
This figure suggests that the vocal chord is opened by pressing the hard material to the cartilago corniculata.


You might have LDP?

If you experience sensations in your throat, shortness of breathe, find it hard to swallow (make abrasive grinding sounds when swallowing), or feel pressure in your throat? You may have LDP.
LDP stands for: Larynx Deep Positioning

LDP is when the muscles of the throat stiffen, and the hyoid bone, the thyroid cartilage and the cricoid cartilage move towards the cervical spine a few millimeters.

I reference this term as ‘Larynx Deep Positioning,’ because the larynx is located in a deeper position than normal.

If you cherish your voice, this should be a big deal!

LDP is a condition not disease, which means it can be controlled and treated.
It is not classified as a disease, even if you go to an Otolaryngologist.
An Otolaryngologist is an ear, nose and throat professional. I am an experienced Japanese Voice Care Specialist who is here to guide and educate you from my research and experience in helping treat individuals with LDP.

If you have a problem with losing your voice or swallowing food, a doctor will more than likely diagnose this as a disease and advise further testing and discuss treatment options. However, if it determined that the issues don’t interfere with your normal life, a Doctor will more than likely say “Let’s wait and give it some time to further progress” or “You do not need to worry about this issue right now, it may resolve itself.” Both of which, if an individual is suffering are difficult to accept or hear.
If you are persistent about this problem, a Doctor will eventually refer you to a Specialist. Finally, the individual suffering gives up and starts to explore hollistic approaches, oriental medicine, meditation, over the counter topicals, all in desperation … which in the end do not resolve the problem.

The following is my evaluation guide and alternative approach in understanding and determining the condition of LDP

1) Start with a visual examination of the Larynx: Check its location depth, see if the laryngeal prominence seems hidden, and if you can see a concave area along the edge of the thyroid cartilage.
2) Make clicking sounds: If the thyroid cartilage moves from side to side without pushing (gliding), or if it makes an abrasive grinding or crunchy sound.
3) Measure the muscle hardness using a meter: LDP…40-80Tone – Normal…20-30Tone –  Good condition…10-20Tone
4) Choking often: If you choke a lot, even when you do not have a cold or bronchitis, this can also be considered an important symptom resulting from LDP. Most people overlook this, because the in most cases the symptoms are very minor.
5)Be mindful of slight individual variances: I use several different tests with my patients, focusing on the individual’s situation and variance degrees which in turn determine whether LDP is in fact the condition suffered.

(scroll down to view photos of a normal larynx and one with LDP)

So, does LDP heal naturally or not?
If the individual displays minor or short term symptoms they can possibly recover naturally by taking deep breaths, relaxing, stretching the neck muscles often, combined with taking a sufficient amounts of rest and/or sleep. With minor cases most are unaware they even have LDP.
If the symptoms are long term, LDP becomes chronic and most people start to become aware that they do have some sort of throat condition. Long term LDP, means (for more than a few months) the individual did not heal naturally due to the degree of their LDP or even lifestyle habits. In these cases, treatment is necessary for any means of symptom relief and recovery.

The Mechanics of LDP are muscles constricting, tiring and/or swelling of the muscles, making it difficult to extend by themselves. This can often be observed and diagnosed by the severity of inflammation present.
For example, when the muscles contract (tighten), and then return to extend again, with LDP those muscles become rigid from the contracting action. The antagonistic moves to the opposite direction and pulls the other muscle, similar to a seesaw. This action is what prevents the muscles from contracting normally. Soreness, coarseness, tightness, and swelling follow.

Another important factor, is if there is no distinct antagonistic observed around the larynx. Most muscles have a vector of direction leading vertical to the cervical spine. Unfortunately, if you shift or strain the muscles in your throat, it causes the larynx to be pulled to a deeper position than normal.
Eating disorders, especially when suffered daily, also causes swelling of the throat muscles. Due to the overextending and constriction of the muscles, most always lead to LDP and affect the voice. Be mindful, if you keep having these symptoms, it will result in a poor voice quality, and could even cause permanent damage.

The phenomenon is as follows:
(1)When the throat is deep-set,the resonance chamber narrows, especially the pharyngeal resonance chamber in the back of the hyoid bone. It loses resonance and changes the sound of the voice significantly.

(2)It’s narrow between the thyroid cartilage and the hyoid bone, creating poor blood circulation, causing lack of oxygen, making it difficult to disperse nutrition and fluids to the vocal chords. Consequently, stamina runs out easily for phonation and dryness will occur. (It’s easier to catch a cold or the flu when the throat is dry because the mucosa is more vulnerable)

(3) Suprahyoid muscles are negatively affected, which make it difficult to produce the sound of speech, when the associated muscles are stiff.

(4)The arytenoid cartilago corniculata is pressured, forcibly moved and rotated to the outside and glottis is opened. Noticeably, the voice will crack and sound coarse.

LDP Observation

Note1:It is all too common when seeking a diagnosis of LDP that many Doctors state that, ‘there is no obvious problem with your throat ‘ and ‘maybe this issue is due to stress or recent lifestyle changes’ or is sometimes misdiagnosed as ‘abnormal sensation syndrome of throat.’ Although, I have seen in some rare cases that LDP was ’caused’ by extreme stress and or muscle tension, but it’s form is obviously much more than just that.
Note2:As a Voice Care Specialist I have seen many cases involving LDP over the years. I started this blog to educate people, share my experiences in cases and studies, and help those suffering who are looking for answers.
Note3:If you feel like choking often, due to stress, reflux esophagitis, or any of these chronic symptoms, please seek a Medical Diagnosis to avoid any further damage. After a diagnosis is found please seek treatment, as if it is LDP it can be managed and recovery/relief is possible.

I have many other posts on this blog relating to research as well as individual cases involving Larynx Deep Positioning (LDP).
My purpose is to make a difference in the Medical world as well as individuals, who wish to learn more about the condition and treatment options for those who have LDP.
