“The ear is the gathering of the clan chakra.” The use of the auricle to diagnose diseases has long been recorded in the Yellow Emperor’s Classic of Internal Medicine. Ancient medicine has already noticed that by observing the position size, thickness form and color of the auricle to diagnose the function of internal organs. The theory of auricular acupressure is three-fold: one is the theory of Chinese medicine, which believes that most diseases are caused by disorders of labor and leisure, emotional and mental disorders, poor diet, or loss of nourishment after illness and disharmony in the stomach, and are related to the heart, liver, lungs, kidneys, and spleen. Ear acupuncture is used to treat diseases through the action of the meridians to run the qi and blood and regulate the yin and yang organs. The ear is closely related to the meridians, and the chapter on “The shape of the disease in the internal organs of the evil spirit” says: “The twelve meridians, three hundred and sixty-five loops, whose blood and qi all go up to the face and go to the empty orifices, whose essence and yang qi go to the eyes and are the eyes, and whose other qi goes to the ears and is the hearing.” The meridians that flow directly through the ear are: the foot Shaoyang Gallbladder meridian and the hand Shaoyang Sanjiao meridian, which both enter the ear from behind the ear and go to the front of the ear. The foot Yangming Stomach meridian, which follows the cheek carriage up to the front of the ear. Hand Sun Small Intestine meridian, enters the ear from the sharp canthus of the eye. The foot sun bladder meridian, from the top to the upper corner of the ear. The ear is also closely related to the internal organs. The “Spiritual Pivot – Pulse Degree Chapter” says: “Kidney Qi is connected to the ear. The Su Wen – the organ qi Fa Shi Lun said: “The liver disease, …… deficiency then the eyes do not see, the ears do not hear.” The Suwen – the organ qi Fa Shi Lun said: “The lung disease …… deficiency is less qi, can not report rest, deaf quarrel dry.” The second is the theory of holographic medicine. According to the theory of holographic medicine, all parts of the body can be expressed as the whole body, so the diseases of the whole body can also be reflected in a certain part of the body. The adjustment of this positive response point can treat certain diseases in the body. Third, Western medicine believes that the nerves in the ear are richly distributed, and that regular stimulation of the nerves in the ear (i.e., auricular acupuncture) can regulate the excitatory and inhibitory states and bring them into balance, thus achieving the effect of treating diseases. 1. Surface anatomy and distribution of the auricle 1. Anatomical position (1) Ear wheel: the part of the outer edge of the auricle that curls forward. (2) Nodule of the auricle: a slightly hypertrophic nodular protrusion above the outer part of the auricle, also known as Darwin’s node. (3) Pedicle of the ear wheel: the transverse protrusion of the ear wheel deep into the cavity of the earnail. (4) Para-auricular chakra: a bulge opposite to the auricular chakra, medial to the inner chakra. (5) Superior and inferior peduncles of the contralateral ear chakra: upward and downward branches of the contralateral ear chakra. (6) Triangular fossa: triangular depression between the upper and lower legs of the opposite ear wheel. (7) Ear boat: The concave groove between the ear chakra and the opposite ear chakra. (8) Ear screen: The flap-like protrusion in front of the auricle, also called the ear bead. (9) Opposite ear screen: the bulge on the upper part of the earlobe opposite to the earlobe. (10) Supraspinal notch: the depression between the upper edge of the ear screen and the foot of the ear chakra. (11) Inter-screen notch: the depression between the ear screen and the opposite ear screen. (12)Wheel screen notch: the depression between the opposite ear screen and the opposite ear wheel. (13)Earnail boat: The part of the earnail above the foot of the earwheel. (14) Earnail cavity: the part of the earnail below the foot of the earwheel. (15) Earlobe: the lowermost cartilage-free lobe of the auricle. 2.Distribution The distribution of the ear points on the front of the auricle is like an inverted fetus in the womb, with the head facing downward and the arms and legs facing upward, and the distribution of the organs of the internal organs and limbs have a certain regularity. Earlobe: equivalent to the face; ear screen: equivalent to the nasopharynx; opposite ear screen: equivalent to the head; opposite ear wheel: equivalent to the trunk; opposite ear wheel upper foot: equivalent to the lower extremity; opposite ear wheel lower foot: equivalent to the buttocks; ear boat: equivalent to the upper extremity; earnail cavity: equivalent to the thoracic cavity; earnail boat: equivalent to the abdominal cavity; ear wheel foot: equivalent to the septum; trigeminal fossa: equivalent to the pelvic cavity; interscalene cut: equivalent to the endocrine. Second, the operation method of auricular pressure 1, auricular visualization The ear and the meridians, internal organs not only have correlation, but also have relative specificity. Diseases in the meridians and internal organs will produce a reaction in the corresponding part of the auricle, which can be used to diagnose diseases. Observation of discoloration, deformation, papules, vascular changes, and flaking of the auricular skin is an effective method of auricular diagnosis. Acute inflammatory diseases can be seen as patchy congestion, redness, white in the middle, redness at the edge, capillary expansion, bright red color, seborrhea and luster; chronic organic diseases can be seen as dotted or patchy white elevation or depression, white papule, no seborrhea and luster, swelling can be seen; various skin diseases can be seen as bran-like desquamation, papule, thickening of skin texture, thickening, dark brown; tumor can be seen as nodular elevation or dotted dark gray. The general principle of auricular trial rule: acute phase color is more red, chronic phase color is white or sunken, easy to rub flaking is inflammation, squamous combined with dermatosis, surgical scars white stripes or crescent-shaped, dark gray nodular elevation see cancer. 2.Operation and technique Operation method: (1) Probing ear points: find positive reaction points, carry out identification and typing, make clear diagnosis and determine treatment plan and point selection formula. (2) Disinfection: use 75% ethanol cotton balls or iodine volts to clean and disinfect the auricle, so that the adhesive tape and pressure can be easily applied. (3) Pressure: fix the auricle with the left hand and hold the adhesive tape with the right hand to the auricular point, or use the pressure probe to hold the prepared adhesive tape on the auricle and press it firmly for a few moments. (4) Course of treatment: Each time the pressure is applied to one side of the ear point, the two ears in rotation, 3 to 7 days to change once, or both ears can be pressed at the same time. For acute diseases, the duration can be slightly shorter, while for chronic diseases, it can be slightly longer. Patients can apply pressure and knead 4~5 times a day, 1~2 minutes per point, every 5 times a course of treatment, with 3~4 days rest between treatments. 3, pressure techniques: (1) the pressure method. With the thumb and index finger on the front and back of the auricle, relative pressure on the auricular point of the paste, the thumb and index finger can be pressed while moving left and right or do circular movement, looking for the obvious location of inflation. Once the “sensitive spot” is found, continue to press for 20-30 seconds to make the pressed area feel sunken, heavy, swollen and painful. The amount of stimulation is even greater when the pressure is applied on the front and back of the auricle. The pressure is applied 3 to 5 times a day. This method is a strong stimulation technique and belongs to the diarrhea method. It has a good analgesic and anti-inflammatory effect on real evidence, young force-like people, visceral spasmodic pain, somatic pain and acute inflammation. (2) Direct pressure method. Use the fingertips to press the patch vertically until the patch produces a feeling of distension and pain. Continuous pressure for 20~30 seconds, with little interval, repeat the pressure, 4~6 times per acupuncture area, 3~5 times per day. This method is also a strong stimulation technique, the intensity is weaker than the pair of pressure method. (3) point pressure method. Use the fingertips to press the ear point with one pressure and one release, intermittently, at intervals of 0.5 seconds each. This method should not be too heavy, to the pressure to feel swollen and slightly tingling, each point can be point pressure 20 ~ 30 times each time, 3 ~ 5 times a day, this method is also a tonic method. (4) kneading method. Use the finger belly to gently compact the patch, and then clockwise drive the patch skin rotation, to the patch at the swelling, soreness, pain or a slight tingling. Each time each point is gently rubbed for 4~5 minutes, 3~5 times a day. This method is a tonic method.
