    The Head Mirror

    The head mirror is a simple yet effective tool that has been used for over 150 years to illuminate the nose and throat during medical examinations. It consists of a small concave mirror with a central hole secured by a headband. The physician reflects light from a source behind the patient into their nose or mouth using subtle head movements to adjust the size and intensity of the beam. While some newer light sources are gaining popularity, the head mirror remains a symbol of the field of otolaryngology due to its long history and continued use.

    The head mirror, still in use with a design originally created more than 150 years ago, remains a

    symbol of ENT, Just like a stethoscope is for physicianss.

    The current design is credited to Dr. Johann Czermak ,who developed a prototype in Budapest in
    1857. Remarkably simple in design and effective in use, it has stood the test of time. The head
    mirror consists of a small concave mirror with a hole in the center of it, secured by a headband.
    When not in use the mirror is reflected upward. A light source is placed behind the patient’s head,
    the mirror is flipped down, and the light is then reflected into the patient’s nose or mouth. The
    intensity and size of the light beam reflected is adjusted by the physician moving his or her head
    back and forth. It takes a bit of practice to do this. The eye hole in the center of the mirror allows
    binocular vision by the examiner. The light is bright and without shadows. It frees up both hands for
    the examination since the doctor doesn’t have to hold a flashlight or penlight.

    Although otolaryngologists of a certain generation generally still use the head mirror, its use is slowly
    being replaced by either fiberoptic or LED headlights. These are currently used in most training
    programs.

    Bull's lamp: is a semi mobile source of illumination. It has a 100 watts milk white bulb which
    provide the source of illumination. This light is focussed with theplano convex lens placed in front
    of the bulb. Ideally the Bulls lamp is placed 6 inches above and behind the left shoulder of the
    patient, at the level of left ear of the patient.

    The examiner and the patient must be conveniently be seated on adjustable stools. While using a
    Bull's lamp the examiner must focus the light using a head mirror to illuminate the patient.

    The head mirror is a concave mirror. It has a hole in the centre. The approximate focal length of
    the mirror is about 10 inches. It has a plastic head band with a lever with 2 ball and socket
    joints. The joints are at right angles to each other.

    Focusing the light with head mirror: The art of focusing the light to the desired spot comes only
    with practice. But there are certain basic steps which must be followed.

    1. The patient sitting on the stool must be at the same level as the doctor.

    2. The patient's legs must be placed to one side of the examiner.

    3. The distance between the doctor and the patient must not be more than 8 inches (i.e. the focal
    length of the head mirror).

    4. The mirror is fixed over the right eye in such a way part of the mirror touches the nose.
    5. The mirror is adjusted in such a way that the right eye sees through the hole in the mirror. The
    mirror is adjusted while keeping the left eye closed and the right eye is kept open. Then both
    eyes are opened.

    Clair's head light provides mobile illumination. The source of light is from a small 9 volt bulb. It is
    placed in front of a adjustable concave mirror. The mirror and the bulb are held via a plastic
    adjustable head band. The power supply to the bulb is from a 9 volt transformer. The major
    advantage of this illumination is that it is freely mobile and the patient may be examined in
    various positions. This illumination is highly useful while performing operative procedures inside
    the theatre.
