CAMPOS, GUILLERMO. RECENT TECHNOLOGICAL ADVANCES IN DIAGNOSIS AND TREATMENT OF THE LARYNX AND UPPER AERODIGESTIVE TRACT. rev.fac.med [online]. 2012, vol.20, n.2, pp.65-81. ISSN 0121-5256.

Continuous technological developments in recent years have allowed a better understanding of the anatomy and physiology of the vocal folds and the upper digestive tract. Diagnostic techniques such as high speed laryngoscopy, videokymography, in office high resolution close up laryngoscopy and esophageal impedance with manometry are very important tools in modern day clinical practice. As far as treatment is concerned, development of laser equipments coupled to robotic systems, fibers to deliver different laser wavelengths to specific places, and instruments to be used through flexible scopes, broadened therapeutic possibilities and, in selected cases, have made it possible to perform minimally invasive procedures with no need for hospitalization. The purpose of this study is to review and analyze technological advancements for diagnosis and treatment of the diseases of the upper aerodigestive tract, their feasible applications and limitations. It is a descriptive study of literature review regarding the topic. A monograph and a revision of relevant literature accessible on indexed publications related to different currently available methods for studying the upper aerodigestive tract diseases, as well as new alternatives from the therapeutic point of view are presented. An analysis of important technical aspects of each option, either diagnostic or therapeutic is performed with the aim of elucidating their possible clinical applications, advantages, disadvantages and contraindications.

Keywords : Laryngoscopy; stroboscopy; manometry; kymography; impedance; transoral laser microsurgery.
