E.N.T. Specialist (oto-rhino-laryngologist):-
A doctor who specializes in diagnosing and managing diseases (by medicines or surgery) of Ear-Nose and throat.
Evaluation of the ear, nose and throat requires good source of light. Most important is, no doubt, skilled hands and experienced eyes.
Some instruments and common terms used in E.N.T. practice:
Head-mirror and bulls lamp: –
Bulls lamp placed above and behind the patient’s shoulder has got a bulb and Plano-convex lens to send focused light to head mirror.
Head mirror (I like to describe it as “naag-mani”), has special concave lens to reflect light from bull’s lamp. The examiner sees through the hole in the center of the mirror for binocular vision.
Some professionals use Head-light in place of bull’s lamp and head mirror.
Endoscopy unit: –
light source, camera and nasal endoscope are being used in a modern
ENT set-up for video demonstration of otherwise hidden- from patient’s-cavities.
Tongue depressor: –
To depress tongue and examine oral cavity.
Nasal speculum: –
Help in viewing inside of nose, procedure to inspect nasal cavity is called anterior rhinoscopy.
Laryngeal mirrors: –
Used to examine larynx and laryngo-pharynx. Doctor will hold your tongue and will see reflection of larynx in the mirror that is why it is called indirect laryngoscopy.
Video-laryngoscopy is routinely used now a days using telescope.
Postnasal mirror: -used to examine nasopharynx and posterior part of nasal cavity, a procedure called posterior rhinoscopy.
Inserted into ear to see inside of ear canal and ear drum.
It is battery operated device with magnifying glass, gives magnified view of ear drum.
Otoscope is most essential tool in the hands of otolaryngologist; I often use it to inspect ear, nose and throat of infant, child or bed-ridden patients or places (like rural-camps) where an equipped E.N.T. set-up is not present.
Siegel’s speculum: – It helps to test mobility of ear drum, a very essential part of ear examination.
Jobson-Horne’s probe: –
I call it “chhoti jadu ki chhadi” (tiny magic-stick). On the one end of the probe cotton can be applied and used to clean ears of any discharge. Other end has got ring like structure to remove wax, dried secretion and foreign body.
(Tilley’s or Hartman’s) for packing or grasping.
Eustachian catheter: – To see the patency of Eustachian tube.
Suction-apparatus: – To suck out discharge or blood from ear or nose for detailed examination.
Ear microscope (operating microscope): –
To examine the ear drum more precisely under magnification, a procedure called Examination under microscope (EUM).
It gives the doctor the freedom to use suction and other Instruments in the ear.
Microscopy is used to clean discharge, to inspect ear drum, middle ear or any pathology before surgery, and to remove impacted wax or foreign bodies from ear.
To roughly assess degree and type of hearing impairment.
Pure tone audiometer and impedance meter:-
To test degree and type of hearing-loss.
