How is anterior rhinoscopy performed?

Generally, anterior rhinoscopy is a basic examination method in otolaryngology, primarily using a sidelight source reflected and focused by a head mirror to observe the internal structures of the nasal cavity. The specific procedure is as follows:

1. The patient should sit upright or lie slightly reclined, maintaining a comfortable position.

2. Apply simple topical anesthesia to the nasal cavity to minimize discomfort.

3. The examiner wears a head mirror and gently inserts the nasal speculum into the patient's nostril to examine the interior of the nasal cavity.

4. After completing the examination, slowly withdraw the speculum from back to front.

This procedure requires professional expertise. To ensure accurate results, it is recommended to visit a正规 hospital and undergo the examination under the guidance of a qualified physician. If any abnormalities are detected, prompt medical consultation is advised for appropriate diagnosis and treatment under a doctor's supervision.
