    Area of Science:

    • Otolaryngology
    • Medical Photography
    • Laryngology

    Background:

    • Microlaryngoscopy requires specialized photographic techniques for documentation.
    • Existing methods may be complex or require specialized equipment.

    Purpose of the Study:

    • To describe an uncomplicated, routine photographic technique for microlaryngoscopy.
    • To enable adoption by users of the Zeiss surgical microscope.

    Main Methods:

    • Utilized a Zeiss surgical microscope with specific settings (9.5 A, 7.6 V bulb, shutter 22, magnification 16x or 25x).
    • Employed Kodak Ektachrome HS film (125 ASA) with a 1/4 second exposure time.
    • Focused on aligning the microscope's optical axis with the laryngoscope's central axis in relaxed, intubated patients.
