SPONSORED FEATURE Hi-tech lasers and robots bring ENT surgery to the next level Dr Vyas performing surgery using the The Medrobotics Flex System Surgical odyssey in space age For the most part of the 20th century, ENT surgery was fairly rudimentary in its application. Access to the ear, nose and throat was hindered by the lack of equipment that could illuminate these small and poorly visualisable orifices with an added feature of secretions such as saliva, mucus and in the surgical 40 MARCH 2020 context – blood and pus. In addition, there was always the challenge of an altered anatomy from the very pathology that was being treated. Given the intricacies surrounding the head and neck with its plethora of important nerves, arteries and structures, the need to be able to magnify the operative field and minimise the size of the instruments to fit into the field became the necessity that mothered these inventions. Lasers Nobel Laureate Albert Einstein postulated the ability to amplify light by the stimulation of radiation emissions (“laser” is an acronym for “light amplification by the stimulated emission of radiation”) almost a century ago. It was not until Theodore Maiman, an American engineer designed the progenitor of the laser – utilising microwaves instead of light (the “maser”) and thereafter using a crystal of ruby to create light amplification, that the first solid state laser was invented. Further development of lasers allowed for cheaper materials to be used as the media for light amplification. Indian scientist Dr Kumar Patel’s seminal work at Bell Laboratories in the United States resulted in the development of the now ubiquitous carbon dioxide (CO2) laser. GlobalHealthAndTravel.com T HE last five decades have witnessed several advances in otolaryngology (ear, nose and throat surgery). The development of a variety of highly specialised technologies, designed by engineers to be used by ENT surgeons to deliver better treatment for their patients, has been the driving force behind minimally invasive surgery for benign and malignant conditions requiring surgery with or without reconstruction of the head and neck. The impact these engineering feats have had are quite staggering on the reduction of disfigurement to the individual, concomitant collateral injury to structures uninvolved and, most importantly, quality of life. The ENT surgeon has, quite simply put, a rather important role in aiming to preserve bodily functions that are often taken for granted – such as breathing, speaking, swallowing and the majority of the “special senses” which include hearing, balance, smell and taste.
