Rhinitis is a common and frequent disease, which brings many inconveniences to the patients’ working life. In the past, traditional treatment is often ineffective, so our department proposes the technology of needle knife + pterygopalatine ganglion stimulation for rhinitis treatment based on the domestic and foreign rhinitis treatment technology, especially the technology of acupuncture of pterygopalatine ganglion by Professor Li Xinwu from the Department of Otorhinolaryngology of Beijing Tongren Hospital. This technique is less painful and more effective, and the preliminary clinical observation shows significant efficacy. The nasal vasodilation function is innervated by sympathetic and parasympathetic nerves. Sympathetic nerves can make the function of vasoconstriction, and thus can make the blood flow in the nasal mucosa and cavernous body become smaller and the secretion of glands decrease. The parasympathetic nerve, on the other hand, has a vasodilating function, which causes excessive congestion in the cavernous body, expansion of the nasal mucosa, and an increase in glandular secretions. In a healthy state they restrain each other to maintain the balance between the two. Due to inflammation and other pathologies, the balance of the pterygopalatine ganglion is disturbed and an imbalance of sympathetic and parasympathetic functions occurs. Usually the most common is nasal vascular congestion, expansion, mucosal swelling, turbinate hypertrophy, obstructed ventilation, a large increase in nasal mucus, which in turn affects the narrowing of the sinus opening or even blockage, poor drainage, long-term storage of pus in the sinus cavity, or due to differences in the human body, the local response to sensitive sources vary in severity, but mostly manifested as glandular expansion, pale edema of the nasal mucosa, sneezing, these are the above rhinitis, sinusitis or allergic These are the general pathological changes of rhinitis, sinusitis, or allergic rhinitis, i.e., parasympathetic overexcitation and sympathetic inhibition. Of course, the lesions can also lead to mucosal ischemia, smaller turbinates, reduced secretions and dry, crusty nasal passages, and symptoms of atrophic rhinitis, in which the sympathetic nerves are strong and the parasympathetic nerves are weak. The sympathetic nerve in the nose comes from the sympathetic plexus of the internal carotid artery and the deep rock nerve of the superior cervical sympathetic ganglion, the largest sympathetic ganglion in the neck; the parasympathetic nerve comes from the superficial rock nerve, a branch of the facial nerve, and the two synthesize the pterygopalatine nerve to the pterygopalatine ganglion, with postganglionic fibers distributed in the upper, middle and lower turbinates as well as the nasal septum and nasopharyngeal roof. The new technique of “acupuncture + pterygopalatine ganglion stimulation for rhinitis” is based on the technique of acupuncture of the pterygopalatine ganglion by Professor Li Xinwu of the Department of Otorhinolaryngology of Beijing Tongren Hospital, which integrates the advantages of acupuncture for rhinitis and targets the sympathetic and parasympathetic nerve pathways in the nose (one line) and the three key treatment sites in the neck, pterygopalatine ganglion and nose (three points). The “three points and one line” treatment plan can effectively regulate the balance of sympathetic and parasympathetic nerves in the nose, restore the health of the nasal mucosa, and achieve the purpose of treating rhinitis. Clinical observation shows that after treatment with the new technology of “acupuncture + pterygopalatine ganglion stimulation for rhinitis”, patients can feel better ventilation and breathe smoothly immediately. Generally, the effect lasts for a short time after the first two treatments, ranging from a few hours to two or three days, but after four treatments, the effect is more obvious, and the improvement time of ventilation, runny nose and sneezing symptoms is significantly longer. Some patients may experience a significant increase in runny nose after the first few treatments, which is a normal phenomenon and usually occurs in patients with combined sinusitis. A typical case is a patient with chronic rhinitis combined with chronic sinusitis. After the treatment, there is a large increase of nasal discharge compared with that before the treatment, and before the treatment, the sinus CT shows that the bilateral maxillary sinus and frontal sinus are full of soft tissue shadow. In general, the technique of “needle knife + pterygopalatine ganglion stimulation for rhinitis” has the best effect on chronic rhinitis, followed by allergic rhinitis, and can sometimes achieve very good results for chronic sinusitis. The “needle knife + pterygopalatine ganglion stimulation for rhinitis” technique is generally performed once a week, six times as a course of treatment, and those with poor results can undergo a second course of treatment 2 weeks to 4 weeks after the first course of treatment. The technique of “acupuncture + pterygopalatine ganglion stimulation for rhinitis” can play a good role in relieving and treating rhinitis, but it is still difficult to completely cure, especially for patients with allergic rhinitis, so patients must pay attention to avoid contact with allergens after treatment, pay attention to cold and warmth, avoid cold air stimulation, do not smoke, drink alcohol, in order to make the effect more durable. In order to make the therapeutic effect more lasting.
