The book by Dr. Vasant Oswal and his colleagues is thoroughly written and covers a very wide and expansive breath of knowledge. The overall format of the book is superb, starting from the basic background information on the development of lasers and how they work to their applications in complex procedures. Figures and illustrations are appropriate and informative. The use of end-of-chapter quizzes to reinforce the topic adds to the book, making it more interactive for the reader. In addition, the book includes dedicated chapters on the use of lasers in the pediatric population, an area where laser use is commonly overlooked. Furthermore, the book includes information on other light-based therapies, including photodynamic therapy for the treatment of oral and head/neck pathology. Moreover, future developments using lasers in otorhinolaryngology are discussed and in-office procedures are elaborated. In turn, the book provides a comprehensive and complete overview of lasers and associated techniques that would be useful for a wide audience, from residents to practicing physicians.
