1.1 clinical data. June 2004-July 2005 by a total of my diagnosis and treatment of nasal valve stenosis area with 58 cases. Men and 36 cases, 22 cases of women aged 20 to 69 years old, an average of 44.5 years. History are more than two years, drug therapy ineffective. A stuffy nose for the main symptoms, some accompanied by chest tightness, Bieqi. Of which 15 cases had surgery to the nasal septum, nine cases had to sinusitis surgery, but still left after varying degrees of nasal obstruction. Before nose-and nasal endoscopy: Top nose outer threshold of 12 cases of sudden, small nose-mast after the lower part of 11 cases, nose before the end of the soft tissue swelling Fu-convex 24 cases, inferior turbinate hypertrophy front of 11 cases. All cases are to raise the nasal tip and Cottle positive test positive sign and diagnosis. The patients, except for the back-end and the free margin of inferior turbinate hypertrophy, nasal septum deviation, sinusitis and other causes of the nasal cavity caused by nasal obstruction.
1.2 treatment. Local anesthesia 0 ° Endoscopic nose threshold in the top of the wall in the process, small nose-under after the mast, the front end of inferior turbinate before the end of the nose and soft tissue swelling convex Fu-1 to choose the needle 2:00, 8 W power , Radiofrequency ablation treatment. See in the ablation of the Organization volume was gradually reduced, white, nasal valve area of expansion, the patient is feeling at that time to improve ventilation in the nasal cavity. With only a little or no bleeding. Tu after partial to 0.5 percent chlortetracycline eye ointment. After the first two days and patients can have a stuffy nose-T, check with district local swelling and Jiaodong kind exudation. After three to five days exudation of gradually falling, T-reduction, swelling receded, stuffy nose reduce. Exudation about two weeks of shedding clean. Four weeks after the nasal valve area become stable and the symptoms completely disappear.
1.3 Clinical Evaluation criteria. All patients were followed for more than one year. Preoperative and postoperative year by 10 cm visual analogue score evaluation of patients with nasal subjective feeling. Stata statistical software used to t-test. All the cases as radiofrequency ablation treatment, nasal symptoms, no adverse reactions. VAS score from preoperative after 8.33 ± 0.12 to 2.15 ± 0.64, P 0.01, a significant difference.
Nose nasal valve area is the narrowest part. The traditional sense refers to the nasal cavity and the cartilage of the mutual connection and the transition region. On its side on the nose for the lateral cartilage margin, before the bottom of the inside of the nasal septum , the bottom end of the pear-shaped hole and inferior turbinate front. Nasal valve area is not difficult to narrow the diagnosis, with their hands raised in Normal to pull the nasal tip or nose, nasal symptoms in patients with the diagnosis can be eased. The key is to raise awareness of the region and attention. Previously, the nasal valve area and more attention to a narrow nose threshold top wall, nose and small, in the lower part of inferior turbinate after the front end, etc., at the end of the nose with soft tissue swelling convex Fu less attention. But in our cases, such anomalies are more. Narrow nasal valve area of traditional treatment methods primarily through nasal valve surgery to expand the District cross sectional area to achieve therapeutic purposes. Top outer threshold of the prominent nose, because there are too many surgical resection, a suction when nasal dorsum of the collapse, with the nose and small-mast after the lower part of the same complex surgical operation. Radiofrequency ablation technology through Biaoceng Xia effective organization reduction nasal valve area to expand cross sectional area, nasal discharge valve narrow to achieve therapeutic purposes. As a relatively low temperature to avoid laser, microwave treatment, such as the vice injury. Radiofrequency ablation technology obstructive disease of the good and safety of treatment has been widely recognized. The patients mainly due to soft tissue abnormalities in patients with narrow nasal valve area, due to nasal septum lateral cartilage or bone before the bottom of the deviation caused by a narrow nasal valve area, we still advocate using the traditional method to resolve. In order to prevent scar cartilage narrow or liquefaction, our experience is narrow at the same time multi-site, using intermittent catheter ablation and staging ablation approach, and in accordance with the situation, control of needle depth, shorten the single needle ablation time, reducing the radius of ablation .
