Pääpeiliä

Pääpeiliä is a Finnish term that translates to "head mirror" in English. It refers to a concave mirror used by medical professionals, particularly in specialties like otolaryngology (ENT) and ophthalmology. This mirror is typically worn on the forehead by the user, allowing for hands-free illumination and visualization of cavities within the body, such as the ear canal, nasal passages, or throat.

The design of a pääpeiliä involves a central opening through which the user looks. The mirror itself is angled to reflect a beam of light, often from an external light source like a lamp or a dedicated head mirror light, into the area being examined. The concave shape of the mirror magnifies the reflected image, providing a clearer and larger view of the target anatomy. This magnification is crucial for diagnosing conditions and performing delicate procedures.

Historically, head mirrors were an essential tool before the widespread availability of modern endoscopic equipment. While advanced endoscopes offer more detailed imaging and greater access, the pääpeiliä remains a valuable and cost-effective instrument in many clinical settings, particularly in resource-limited environments or for routine examinations where its simplicity and effectiveness are sufficient. Its use requires skill and practice to direct the light beam and interpret the reflected image accurately.
