It has two blades that open and allow the visualization of the internal structures of the nasal cavity and pharynx. The blades of the Killian's speculum are thin and straight, and the ends are rounded to allow for smooth insertion into the patient's nose or mouth. The instrument is adjusted to accommodate the width of the patient's nose or mouth, allowing for a more accurate and complete visualization of internal structures.
