Nasal endoscopy is mainly used to observe the structural abnormality of nasal cavity, proliferative diseases of nasal cavity and inflammatory diseases of nasal cavity.
1. Structural abnormalities of nasal cavity: for example, nasal septal deviation shows the deviation of nasal septum bone and cartilage, the occurrence of curved deviation, the formation of spines and cristae; nasal septal perforation can be seen in the perforation of the crust, the edge of the perforation of the vesicle, easy to bleed.
2. Proliferative diseases of nasal cavity: nasal capillary hemangioma can be seen on the mucosal surface of the anterior end of the nasal septum and the anterior end of the inferior turbinate, which is small and has a tip, with bright red or dark red color, round or oval shape, mulberry-like, soft and elastic, easy to bleed. Nasal meningoencephalocele: the examination can see the smooth surface of the nasal cavity or nasopharyngeal mass; nasal polyps, nasopharyngeal fibroangiomas and other hyperplasia and occupational disease.
3. Nasal inflammatory disease characteristics: such as atrophic rhinitis can be seen in the nasal mucosa and bone atrophy, nasal space is larger, mucosal dryness, there may be yellow crust attached; chronic hypertrophic rhinitis can be seen in the inferior turbinate mucosal hypertrophy, chronic congestion, secretion viscous; allergic rhinitis can be seen in mucosal pallor and edema, a lot of watery mucus performance.
4. Nasopharyngeal condition: you can observe whether there are adenoid enlargement in nasopharynx; as well as tumors, necrosis, hemorrhage; pharyngeal tube, round pillows and so on. Nasopharyngeal biopsy can be performed under nasal endoscopy when necessary.
When it is necessary to do nasal endoscopy, you can consult the receiving doctor to fully understand the purpose, significance and precautions of the examination.
