A. Indications and contraindications for plasma treatment of rhinitis.
1, low-temperature plasma treatment for rhinitis is generally adapted to various types of rhinitis resulting in nasal obstruction, such as allergic rhinitis, chronic simple rhinitis, chronic hypertrophic rhinitis and other types of rhinitis. 2, low-temperature plasma treatment is beneficial for itchy nose, runny nose and sneezing caused by allergic rhinitis.
3, low-temperature plasma treatment of rhinitis is not suitable for those who have long-term rhinitis has appeared bony hypertrophy, (manifested as point ephedrine and other nasal drops after the nasal congestion can not improve, or improve after a short period of nasal congestion, such patients need surgery) 4, low-temperature plasma treatment of rhinitis if there is a significant septal deviation, or nasal polyps, should be performed at the same time septal deviation correction or nasal endoscopic nasal polyps excision. Low temperature plasma treatment of nasal polyps cannot control their recurrence.
5. Nasal congestion caused by atrophic rhinitis is mostly due to excessive nasal crust and dull nasal sensation. It is not suitable for low-temperature plasma treatment.
The basic principle of plasma treatment for rhinitis is low-temperature ablation, that is, the use of low-temperature plasma radiofrequency energy to ablate tissue at a lower temperature (40-70 degrees), thereby reducing the volume of tissue, so that the surface of the enlarged turbinates can be reduced with almost minimal trauma and improve nasal ventilation, greatly reducing the patient’s pain and shortening the recovery period. In contrast, traditional laser or microwave treatment for rhinitis uses high temperature of more than 150 degrees, which causes thermal damage to the surface of the nasal mucosa and destroys the normal physiological structure of the nasal mucosa. Low-temperature plasma system has been widely used in the field of otorhinolaryngology abroad in recent years for snoring, rhinitis (chronic rhinitis and allergic rhinitis) and tonsillitis, tonsillar hypertrophy, adenoid hypertrophy and other diseases, and has been proved to have good results and advantages.
III. Steps of low-temperature plasma treatment for rhinitis.
1 Before implementing local anesthesia, a vasoconstrictor and surface anesthetic spray are used and saline is injected with local anesthetic in a certain ratio under the mucosa of the inferior turbinate.
2 A Reflex 45 knife is inserted with a plasma knife along the long axis of the turbinate and the ablation pedal key is depressed, with the electrode portion being submucosal. Ablation is performed for 10 seconds at each treatment site.
3 Depending on the size of the turbinate, 1-3 orifices are made. The orifices should be at a certain distance from each other and should not overlap.
4 Each turbinate should have a maximum of 2-3 spots, and each spot can reduce the turbinate volume by about 200-300 mm3.
Four, low-temperature plasma treatment of rhinitis after the care and attention.
1, low-temperature plasma treatment of rhinitis that night or even after a few days after the nasal obstruction will be aggravated, some patients will be significantly increased nasal runny nose, which is mainly due to the inflammatory response of the nasal cavity to plasma energy, 3-10 days after this symptom will be significantly reduced and disappear.
2. There may be a small amount of bleeding after surgery, which is a normal phenomenon, do not be nervous. If there is more bleeding, you need to visit the hospital to deal with the treatment.
3.The first day after surgery should be semi-recumbent position.
4.If the effect of one treatment is not satisfactory, it can be treated again. (One excessive treatment may cause dryness of the nasal cavity, so splitting the treatment is not a bad thing.) V. Advantages of low-temperature plasma treatment of rhinitis.
1, reduce the damage to mucosal tissue, much less damage than the traditional laser and microwave treatment.
2, outpatient surgery, micro-invasive, easy and quick surgery, mild pain, fast recovery.
3, the indications are properly selected, the effect is ideal. Patients with poor results are mostly due to improper selection of indications, accompanied by deviated nasal septum, or nasal turbinate bony hypertrophy is obvious.
Six, low-temperature plasma treatment of rhinitis hospitals and costs.
Informal private hospitals should be wary of the treatment used is not cryogenic plasma equipment for treatment (hanging sheep’s head to sell dog meat), because the equipment is expensive imported equipment, choose a regular hospital to help avoid the price trap and suffer deception.
