You might have LDP?

If you experience sensations in your throat, shortness of breathe, find it hard to swallow(make abrasive grinding sound when swallowing),or feel pressure in your throat? This might be LDP,
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.
I refererence this term, Larynx Deep Position, because the larynx is located in a deep position.
LDP is a condition is not disease, which means it can be controlled and treated.
It is not classified as a disease, even if you go to an otolaryngologist, which is an ear, nose and throat professional.

If you have a problem with loosing 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 does not interfere with your normal life, they will probably say ”Let’s  wait and give it some time to further progress” or ”You do not need to worry about this issue right now”.
If you are persistent about this problem, they will eventually refer you to a specialist.
Finally, they give up and explore hollistic approaches, oriental medicine, meditation, all which do not resolve the problem. .
I have an evaluation guidelines/alternate approach to understand this condition.
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 thyroid cartilage.
2.Make clicking sounds: If the thyroid cartilage moves from side to side without pushing(glide), or if it makes an abrasive grinding or crunchy sound.
3:Measure the muscle hardness 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 look over this, becisause the symptoms are minor.
5:Individual variances: I have a lot of tests focusing on the individual’s situation, that determine whether LDP is the condition suffered .
(I do not decide disease names or diagnose conditions)

So, LDP heals naturally or not?
If it’s minor or short term symptoms, it can be recovered sufficiently by deep breaths, relaxing, stretching of the neck, resting or sleep. With minor cases most are unaware they even have LDP.
If the symptoms are long term, LDP becomes chronic and most are very aware.
This is caused by the muscles constricting, tiring and/or swelling of the muscles which in turn makes it difficult to extend by itself. This can be observed and diagnosed by the severity of inflammation.
For example, when the muscle contracts (tightens), and then returns to extend again, with LDP it becomes rigid from the contracting. 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, and if you shift or strain muscles in your throat, in some cases it causes  the larynx to be pulled to a deeper position.
Eating disorders, suffered daily, also causes swelling of the throat muscles. Due to the overextending and constriction of the muscles, can also 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 hyoid bone. It loses the resonance and changes the sound of the voice significantly.
(2)It’s narrow between a thyroid cartilage and a 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.
If you cherish your voice, this should be a big deal!

LDP Observation
(The latest anatomical result)
Removed the larynx with constrictor muscle of the pharynx.
It seems to be LDP through the condition of muscle.
I edited the photo to the rough sketch (This a conducted autopsy by a doctor)

Note1:The doctor states that ”there is no problem” ”maybe this issue is due to stress” or ”abnormal sensation syndrome of throat”
Note2:I’ve seen many cases involving LDP and believe this kind of damage is caused by the long term chronic sufferers of LDP, but in rare cases can be caused by extreme tension and stress.
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.
