Stroboscopy and High-Speed Imaging of the Vocal Function, Second Edition presents a complete picture of the art and science of stroboscopy. This unique professional resource includes not only comprehensive coverage of the imaging process, but also the disease process that exists in benign lesions, cancer, and neuropathology. Comparisons of normal images with pathologies are included to enhance readers’ diagnostic skills, and the use of stroboscopic images before and after therapy to determine results enhances their clinical skills. The book also covers the entire range of laryngeal imaging for diagnostics, including rigid endoscopy, videostroboscopy, fiberoptic laryngoscopy, and high-speed imaging.
Written by a physician who works in a multidisciplinary environment, the book outlines the roles of the otolaryngologist, speech-language pathologist, voice scientist, and singing teacher in the clinical examination. Unparalleled full-color illustrations appear throughout.

From the Foreword
“Dr. Woo brings new information to the study of the voice through his expertise in stroboscopy, including the techniques to obtain the best video images and to interpret these images. He demonstrates that stroboscopy is one of the clinician’s most relevant working tool. More importantly, he combines the role of stroboscopy with how the tool is used for teaching, patient education, diagnosis, and research. Dr. Woo’s passion for the study of the voice, his unique expertise and talent for sharing his knowledge with others have allowed him to write a textbook that is enjoyable to read and provides a wealth of new visual information about the art and science of the larynx. Dr. Woo also stresses throughout the book that, thanks to the constant improvement in stroboscopy and the unique collaboration between the otolaryngologist and the speech-language pathologist, we have gained a better understanding of the voice and its disorders. Finally, he challenges us to continue to improve our understanding of the human voice by continually seeking innovative technologies, asking thought-provoking questions, and pursuing collaboration among voice professionals.”

Peak Woo Discusses Stroboscopy and High-Speed Imaging of the Vocal Function, Second Edition
“The number and quality of the endoscopic images is quite remarkable and do reflect the size of practice of the author. […]
As before, the second edition is divided into Basic Sciences (the Anatomy, Physiology and the physics of stroboscopic imaging) and then Disorders of the Larynx. In the former there is now extensive coverage of digital high-speed video endoscopy, or videokymography.
Throughout the book the illustrations of videostroboscopy are really well reproduced, but, even better, they are accompanied by a series of on-line examples. By definition, this is an exercise in dynamic movement and the videos are invaluable. Advances in chip-tip video (avoiding the need for fibres) and contact endoscopy and narrow band imaging also reflect recent advances.
In coverage of laryngeal pathology there are at least as many still endoscopic images as those of stroboscopy, making this a great atlas of disease and, so , of relevance to those with a general otolaryngology interest. Chapters cover such topics as Inflammatory, Autoimmune, Granulomatous, Neoplastic, Traumatic and Neurologic abnormalities.
I particularly appreciated a section entitled ‘Who is doing the Examination and what is the Stroboscopy Data Being Used for?’ (p137). This explains the different approaches to voice problems for the otolaryngologist and the Speech/Language Pathologist and the differing value of Stroboscopy for each of them.”

“This is another noteworthy release by Plural Publishing. In this comprehensive textbook, Peak Woo, MD focuses on stroboscopy and high-speed imaging of voice production regarding basic science and laryngeal disorders. Its predecessor, Stroboscopy, by the same author in 2010, can now be replaced with this second edition that introduces a chapter dedicated to high-speed imaging of the larynx that is becoming prevalent in the research of voice production. The volume also contains elaborate details quoting cur-rent research on imaging techniques, enhanced images, and a spectacular array of video files via a companion website hosted by the publisher. The foreword is penned by the author’s professional friend and collaborator, Thomas Murry, MD, who is an equally accomplished voice scientist, researcher, and clinician.
The textbook consists of two parts, “Basic Science” and “Laryngeal Disorders.” The first section deals with the history and principles of stroboscopy and high-speed video imaging. The chapters related to anatomy and physiology of the larynx, histological properties of vocal fold layers, and the effects of disorders on these layers help build the foundation for readers, especially phonosurgeons, to understand the importance of vocal fold imaging in successful diagnostics and intervention… The chapters related to normal and abnormal vocal fold vibration amplify the importance of understanding basic science in clinical intervention of voice.
One of the most valuable resources in this textbook are the chapters that acclimate new clinicians and laryngologists to the set-up, recording, and interpretation of videostroboscopy. Visual analysis, a subjective study, requires extensive training; one can-not be oversaturated with information or experience. The video examples of every parameter involved in stroboscopic evaluation will indeed help to not only increase visual accuracy of findings but also enhance interpretation. These chapters are written for both neophyte and expert. The author also specifies how findings and interpretation can differ between speech language pathologists and laryngologists. This is crucial for students and early stage clinicians in both these professions.
The second section of this textbook, “Laryngeal Disorders,” covers almost all disorders from muscle tension dysphonia to malignancy of the larynx. In addition to giving an overview of these functional, organic, and neurogenic disorders, these chapters also include histopathology as and when needed, stroboscopic findings and its relevance to diagnosis and treatment, including phonosurgery.
Overall, this is a definitive source for clinicians, voice teachers, and re-searchers in the field of speech science, vocal arts, and medicine.”

“When I was asked to review this book, I was really looking forward to receiving it…Needless to say, it did not disappoint. The author, Peak Woo, is well known in laryngology circles and this is the second edition of this very informative book. This 437-page book is organized into two roughly equal parts. The first part consists of 12 chapters and is a detailed account of basic sciences, anatomy, mechanics and introduction to stroboscopy. The latter part is specifically on laryngeal disorders. There are associated web pages that house the 4k videos accompanying the text – these really help to add context.
This book will appeal to ENT surgeons with an interest in laryngology, as well as speech and language therapists. It has incredibly clear descriptors and possibly the best explanation of stroboscopy that I have ever read. It even goes so far as giving a historical narrative to stroboscopy from its 19th century evolution, from slits in wheels and laryngeal mirrors to modern-day high-quality digital image capture.
The anatomy and physiology within the first part is detailed enough for the majority of ENT surgeons and those in training for their final exam. The images and diagrams are of very high quality and will further aid one’s understanding. I particularly enjoyed the chapter on videokymography, mainly because it is something new and not used in my everyday practice; although after reading this chapter, I wish it was. Part one concludes with some good practical information on how to set up stroboscopy, as well as interpreting the images.
Part two is more focused on laryngeal disorders and, whilst this text is not an atlas of laryngology, there are some very high-quality images. It focuses on more common laryngeal pathology that anyone with an interest in laryngology will encounter on a frequemt basis. There are lots of high-quality montages explaining the effect of this pathology on the cords. Where surgery is the management of choice for these conditions, there is a small operative note explaining the steps involved.
The section on vocal fold paralysis paresis is particularly useful and often debated at meetings; here, it is summed up in a few pages.
Overall, it is clear why Peak Woo is regarded as an expert laryngologist, and this book highlights Peaks’ passion to pass on the information for one generation to the next. I would give this book 5/5/ and would encourage anybody undertaking and laryngeal work/voice clinic to read it just to further aid their own understanding.”
