Nose Air Passage 'Non-Valve' New Criteria for Stenosis Diagnosis are Announced

The nasal nasal nasal valve (INV) refers to a narrow passage through which air flows from the nose. Narrow sinus valve (INV) stenosis, which narrows this space, is one of the main causes of nasal congestion. This study proposes an indicator that can objectively evaluate the stenosis through CT, acoustic nasal airway test, and strain coattles test. The research by Professor Lee Kun-hee's team was recently published in the journal 『Clinical and Experimental Otorhinolaryngology』.
The nasal nasal nasal valve (INV) refers to a narrow passage through which upper air flows from the inside of the nose. Narrowing this passage is called nasal nasal nasal valve (INV) stenosis, and usually occurs when the septum is bent or the sidewall of the nose is weakened. When nasal sinus valve (INV) stenosis occurs, the air passage narrows, increasing air resistance, resulting in nasal congestion.
If nasal nasal nasal valve (INV) stenosis continues, not only simple nasal congestion but also the risk of various breathing-related diseases increases. As the air passage narrows, symptoms of suffocation during sleep appear repeatedly, which can lead to sleep apnea. In addition, if nasal congestion persists, inflammation in the nose can occur, and if it gets worse, sinusitis can become chronic. If the air does not pass through smoothly, asthma or allergic rhinitis can also worsen.
In the past, angle measurement using CT scans was mainly used to diagnose nasal nasal nasal valve (INV) stenosis. However, there was a problem that errors could occur depending on the patient's anatomy or mucosal condition. Professor Lee Kun-hee's team at Gangdong Kyunghee University Hospital proposed objective evaluation criteria in this study to overcome these limitations.
The research team analyzed data from 93 patients (a total of 186 non-valves) who underwent nasal valve stenosis at Gangdong Kyunghee University Hospital. The subjects of the study were adult patients over the age of 18, except for those with chronic sinusitis or nasal polyps, and the exact cross-sectional area of nasal nasal valve (INV) was measured with three tests: strain coil test, acoustic nasal airway test, and CT test.
The modified coil test is a test to check whether the nasal congestion is relieved by allowing the patient to breathe in while the medical staff uses a cotton swab to support the nasal nasal valve (INV). If you feel that nasal congestion has been improved through this test, this indicates that the nasal nasal nasal valve (INV) has been constricted.
The acoustic nasal airway test is an acoustic nasal measurer that generates sound waves into the nose and checks the cross-sectional area and structural changes of the nasal cavity through reflected acoustic signals. The mean value measured three times for each patient was recorded, which was used as a useful indicator for objectively grasping the actual internal structure of the nose and diagnosing stenosis. The area, volume, angle, and sidewall thickness of the nasal nasal nasal valve (INV) were measured on 3D CT images and used as objective indicators for stenosis diagnosis.
The research team objectively evaluated nasal nasal nasal valve (INV) stenosis through deformation coil test, acoustic nasal airway test, and CT test results, and statistically analyzed the difference between the stenosis patient group and the non-stenosis group.
As a result of the study, it was confirmed that patients with stenosis had a smaller nasal nasal valve (INV) area measured on the CT axis plane and a smaller minimum cross-sectional area of the acoustic nasal meter compared to the non-stenosis group. This reveals that the cross-sectional area of the nasal nasal valve (INV) and the minimum cross-sectional area obtained by acoustic nasal measurements can be a more objective and reliable criterion for evaluation.
More standardized evaluation indicators for the diagnosis of nasal nasal valve (INV) stenosis are expected to not only increase the accuracy of treatment, but also affect the preparation of insurance coverage standards. This is of great significance in helping standardize related treatments in the future by providing a basis for objectively proving the necessity of nasal nasal vial (INV) surgery.
Professor Lee Kun-hee said, "By more accurately diagnosing nasal nasal valve (INV) stenosis through a modified coatle test and an acoustic nasal meter, we are expected to be able to establish a treatment plan suitable for the patient."," he said.
