An Aural Speculum is a conical, hollow instrument used to gently widen and straighten the external auditory canal for clear visual examination of the ear canal and tympanic membrane. It is commonly used by ENT specialists, general physicians, audiologists, and veterinarians. The speculum attaches to an otoscope, microscope or headlight system, enabling illumination and magnification during diagnostic and minor surgical procedures. Reusable types are generally made of surgical-grade stainless steel, while disposable versions are made from medical-grade plastic.

Q1. What is an Aural Speculum (AS)?

It is a cone-shaped instrument used to widen the ear canal for examination of the eardrum and ear structures.

Q2. What is the difference between Reusable Aural Speculum (RAS) and Disposable Aural Speculum (DAS)?

Reusable models are stainless steel and autoclavable; disposable models are plastic and intended for single use.

Q3. What sizes are used for children and adults?

Children generally require 2–4 mm sizes, while adults use 4–7 mm sizes depending on canal width.

Q4. Can Aural Speculum (AS) be used for animals?

Yes, veterinarians use them to examine ear canals of dogs, cats, rabbits, and other animals.

Q5. How is a Reusable Aural Speculum (RAS) sterilised?

It is cleaned with enzymatic detergent, then autoclaved at 121–134°C and stored in sterile packaging.
