For the treatment of chronic hypertrophic rhinitis, in addition to etiological treatment, the following methods are applied to reduce the turbinates and relieve nasal congestion and other symptoms. 1.Inferior turbinate submucosal sclerotherapy injection is suitable for early hypertrophic rhinitis, commonly used drugs are 80% glycerin or 20% sulfathiazole, or 50% glucose solution, or 5% sodium cod liver oil. After surface anesthesia, the injection needle is stabbed into the submucosa from the anterior end of the inferior turbinate backward to near the posterior end of the inferior turbinate, then the needle is slowly withdrawn, and the sclerosing agent is injected while withdrawing the needle, and the injection volume is about 1ml. According to the contraction of the inferior turbinate 2 to 10 days after the injection can be repeated, generally 3 times as a course of treatment. Sclerosing agent injection should be noted: (1) the injection needle thickness is appropriate, too thick easily caused by bleeding, too thin oil drug is not easy to inject. Injections such as back to draw blood, should be changed to the injection site. (2) an injection volume is not too much, in order to make the mucosa white, so as not to cause mucosal necrosis. (3) If a systemic reaction occurs during injection, stop the injection immediately and make the patient lie down with the head slightly lowered. (4) To prevent blindness or visual impairment due to retinal artery spasm, a rapid vasodilator such as isoamyl nitrite should be prepared. (2) Submucosal electrocoagulation of inferior turbinate Use high-frequency current to coagulate hypertrophic tissue to produce scar contraction. After surface anesthesia, a fine needle is used to stab into the mucosa at the front end of inferior turbinate several times successively, reaching the posterior end of inferior turbinate from front to back without touching the bone, and then coagulate while retiring the needle. 3.Cryotherapy Place the head end of hyperbaric oxygen freezer (-50℃～-60℃) on the hypertrophic part of inferior turbinate for about 2 minutes; if liquid nitrogen freezer is used, the time should be shortened accordingly because the temperature can be lowered. Pay attention to complications such as pain, swelling, adhesions, etc. when freezing. 4.Simple inferior turbinate mucosal resection The patient is placed in sitting or semi-recumbent position, and 1% dicaine is used for nasal surface anesthesia, and 1% lidocaine containing a small amount of 1‰ epinephrine is injected under the inferior turbinate mucosa 1~2ml, and the diseased mucosa of the inferior turbinate is removed with turbinate scissors according to the booking range. Remove the excised hyperplastic tissue, stop the bleeding with epinephrine cotton, and then fill the nasal cavity with petroleum jelly gauze. 5.Excision of hypertrophic mucosa together with bone The method is more or less the same as the excision of simple mucosal lesion, but the difference is that part of the nasal turbinate bone will be excised. In principle, the resection area should not exceed 1/3 of the inferior turbinate. If too much is removed, secondary atrophic rhinitis may occur. Contraindications for partial inferior turbinate excision should be noted: (1) acute inflammation of the upper respiratory tract; (2) hemorrhagic diseases or hemorrhagic qualities; (3) menstruation; (4) serious systemic diseases such as hypertension, heart disease, liver cirrhosis, chronic nephritis, etc.
