Abstract Invention and improving the methods of ENT
examination are closely connected with the technological inventions of the
19th
and 20th centuries. The invention of the classical exam head mirror in 1861
and improvement of the manufacturing of compact and powerful sources of
light (filament lamps) at the time caused the researchers to create new
devices for ENT examination. In particular, a head-mounted electro-mirror
was created, the principle of which later became the basis for the
development of fiber-optic headlamps. The emergence of powerful halogen and
xenon light sources in the mid-20th century and the use of fiber-optics
technology led to the development of fundamentally new mirror less
headlamps. The traditional head-mounted reflector has gradually disappeared
from the practice of an otolaryngologist. For our part, we can see how
fiber-optic headlamps have been progressively replaced by heavy-duty LED
headlamps over the last nine years.
In order to determine the effectiveness of each available headlamp type and
to answer the question of whether there is a benefit in using and
maintaining a reflector headlamp, and to determine which current head-lamps
are effective, we conducted our own research.
Summing up the results, we came to the conclusion that despite its historic
role in the development of otorhinolaryngology, the headlamp reflector
through its low, in comparison with modern illuminators, characteristics
have lost its relevance and, apparently, nowadays can serve as a museum
exhibit.
The head-mounted LED illuminator, a 21st century device, is gaining in
popularity and is gradually becoming the standard for use in primary ENT
diagnosis and during otorhinolaryngological surgical interventions. Its
features such as full autonomy, lightweight, ease of use – especially the
alignment of the light beam with the surgeon's eye – long operating time
without recharging the battery (7 to 30 days) – depending on the
manufacturer and the workload of the device – is beyond competition with any
other head-mounted device for ENT organ examination. |
