The question "How to check DNS nose?" is unclear. It seems to be a misspelling of "How to check in your nose?". This response assumes that the question is about how a doctor might examine the inside of your nose.
How a Doctor Checks Inside Your Nose
A doctor can visually inspect the inside of your nose to check for any abnormalities. Here's how they typically do it:
- Visual Examination: The doctor will use a bright light to see inside your nasal passages.
- Nasal Speculum: According to the provided reference, "the doctor will use a bright light and sometimes an instrument designed to spread open your nostrils." This instrument is called a nasal speculum. It helps to widen the nostrils, providing a better view.
- Endoscopy: For a more thorough examination, "the doctor will check farther back in your nose with a long tube-shaped scope with a bright light at the tip." This procedure is called nasal endoscopy. The scope allows the doctor to see areas that are not visible with a standard examination.
Tools Used for Nasal Examination
| Tool | Description | Purpose |
|---|---|---|
| Bright Light | A light source, often a headlamp or handheld light. | Illuminates the nasal passages for better visibility. |
| Nasal Speculum | An instrument used to gently widen the nostrils. | Provides a wider field of view inside the nose. |
| Nasal Endoscope | A thin, flexible tube with a light and camera at the end. | Allows visualization of deeper nasal structures, such as the sinuses and the back of the nasal cavity. |
