History of the ENT ImageViewer

Introducing the ENT ImageViewer

The American Academy of Otolaryngology—Head and Neck Surgery Foundation is pleased to announce the release of the ENT ImageViewer. This application provides an accessible and easily searchable collection of otolaryngology-head and neck surgery related images.

The ENT ImageViewer would not have been possible without the generosity and vision of Eiji Yanagisawa, MD and his family. The application was initially conceived of and developed specifically to house Dr. Eiji Yanagisawa’s extensive library of Ear, Nose and Throat images. Since then, the Academy received and added a large collection of histopathology images donated by D. Gregory Farwell, MD and his colleagues at UC:Davis. The Academy hopes the application will continue to expand its offerings in the years to come.

Members can ensure the ongoing success of the ENT ImageViewer by actively using the site, promoting it to otolaryngology – head and neck surgery residents and donating images from their practice. Contact the Department of Education to learn more about making a donation.

Launch the ENT ImageViewer.


Dr. Yanagisawa has shared with the Academy his experiences with image-based learning, how he developed his image library and his hopes for the future. Read Dr. Yanagisawa’s words.

undefinedWhen I was an ENT resident at Yale 50 years ago, Dr. John A. Kirchner, then Chief of Otolaryngology, and Dr. Howard W. Smith, then my chief resident, stimulated my interest in clinical photography. Since then, I have tried numerous methods of still photography, cinematography, videography and digital imaging to document the anatomy and pathology of otorhinolaryngological structures.

My interest in clinical documentation began in 1975 when I purchased my first home video color camera (Magnavox CV440). I quickly realized that this video camera could be used for videography of the microsurgery of the larynx and decided to apply this technique of videographic documentation to other areas of otorhinolaryngology. I came to realize that videographic documentation is the most practical and effective means of obtaining a precise ENT diagnosis.

I subsequently published my early works on videolaryngoscopy in 1981, 1983, and 1985; videorhinoscopy in 1986; video-otoscopy in 1987; stroboscopic videolaryngoscopy in 1987 and 1993; and finally videonasopharyngoscopy in 1989. My works were published in 2 books – Color Atlas of Diagnostic Endoscopy in Otorhinolaryngology (1997) and Atlas of Rhinology (2000).

In the spring of 2000, Dr. Jonas T. Johnson, then Coordinator of the Continuing Education Advisory Committee of the American Academy of Otolaryngology–Head and Neck Surgery, asked me if I would be willing to donate my visual library so that the Academy membership would have the opportunity to benefit from this comprehensive digital collection. My answer was an enthusiastic “Yes!” He then proposed that the Academy establish the Yanagisawa Image Library. Owing to the tremendous efforts of Dr. Johnson and Dr. David Eibling, then Chair of the Core Otolaryngology Education Faculty, the Academy agreed to provide financial support for this project.

The Yanagisawa Image Library consists of three volumes : Volume I : The Ear, Volume II : The Nose and Paranasal Sinuses, and Volume III : The Larynx. Each volume consists of both anatomy, and pathology. The anatomy section describes the endoscopic anatomy of the ear, nose and paranasal sinuses, and larynx. The pathology section, the main portion of the collection, describes congenital, degenerative, infectious, inflammatory, neoplastic, iatrogenic, traumatic, neurologic, and miscellaneous lesions. The miscellaneous lesions include high jugular bulb, Schwarze’s sign, cerumen, tympanosclerosis, otosclerosis, foreign bodies, burns, mastoid-cutaneous fistula, keratosis obturans, CSF otorrhea; nasal septal lesions, adenoids, nasopharyngeal mass; amyloidosis, lingual tonsils and dysphonia plicae ventricularis.

The Yanagisawa Image Library is the culmination of my 25 years of personal experience in videographic documentation of Otorhinolaryngology. I have recorded all the interesting and educational images of the ear, nose and throat, both in the office and the operating room. The unique feature of this collection is that most of the pictures were digitized from prerecorded ¾ inch videotapes. I then selected and compiled the best digital images from over 15,000 cases of ENT endoscopy.

The purpose of this library is to provide Academy members with digital images of common and uncommon diseases of the ear, the nose and paranasal sinuses, and the larynx so that Academy members can utilize these images for teaching purposes. It is my sincere hope that these digital images will serve as a useful guide and reference to the understanding of the anatomy and pathology of otorhinolaryngological structures.

I would like to thank Dr. John A. Kirchner, Dr. Howard W. Smith and Dr. Ken Yanagisawa for providing me with some of their valuable images. My special thanks go to my son, Ray Yanagisawa, for his tireless efforts and perseverance in producing superb digital stills from my original video images. This Library would have never materialized without his computer knowledge and skill.

In closing, I would like to thank Dr. Jonas Johnson and Dr. David Eibling for their guidance, encouragement, and vision for bringing this valuable project to completion.
