It can literally involve taking the face and neck apart, including major tissue transplants, and the removal and replacement of cancerous bone, teeth, eyes, and muscle.<\/p>\n<p>A rise in the incidence of head and neck cancers presents a challenging roster of surgical procedures, and I now regularly employ the use of 3-D technology in major reconstructive surgery.<\/p>\n<p>This technology was originally developed in the film industry by pioneering special effects directors such as Steven Spielberg and James Cameron, and its crossover employment in medical science has great potential.<\/p>\n<p>You\u2019d be hard pressed to find another surgeon citing <em>Toy Story<\/em> or <em>Jurassic Park<\/em> as seminal influences, but these groundbreaking special effects have proved inspirational, if unorthodox, reference points in my work as a surgeon.<\/p>\n<p>The technology accurately maps 3-D &#8220;before and after&#8221; models of patients\u2019 heads allowing me to view objects such as tumours from any number of angles, as well conduct &#8220;virtual&#8221; surgery.<\/p>\n<p>Images are initially gathered via CT and MRI scans and then uploaded into an over the counter software package.<\/p>\n<p>The benefits include greater preoperative planning, reduced theatre times, and the ability to calculate various measurements and incisions involving the removal and replacement of damaged bone and tissue.<\/p>\n<p>I am lucky enough to have honed my computer skills over the years from my initial efforts as a teenager modelling 3-D furniture and fruit to my first surgically applied application repairing a fractured cheekbone.<\/p>\n<p><a href=\"https:\/\/blogs.bmj.com\/bmj\/2013\/09\/30\/kavin-andi-pioneering-the-use-of-3-d-computer-imagery-to-rebuild-patients-faces\/ann_facial_reconstruction\/\" rel=\"attachment wp-att-29169\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-29169\" alt=\"ann_facial_reconstruction\" src=\"https:\/\/blogs.bmj.com\/bmj\/files\/2013\/09\/ann_facial_reconstruction.jpg\" width=\"160\" height=\"130\" \/><\/a>One of the most recent procedures captured the media\u2019s attention when, during two seven hour operations, myself and a fellow surgeon removed a large tumour including a portion of a patient\u2019s jaw, left eye, and numerous teeth before beginning the painstaking work of reconstructing the damaged area.<\/p>\n<p>This included removing a portion of leg bone and re-sculpting it into the jaw as well as prepping the jaw for the latter inclusion of dental implants.<\/p>\n<p>The advantage of pre-operative planning meant we could determine the position of the implants in the patient\u2019s iliac crest, scapula, or fibula in virtual space, which saved a lot of guesswork on the operating table.<\/p>\n<p>The next leap in technology will be the use of 3-D surgical glasses with the ability to see through tissues. This will help surgeons to see the microscopic spread of cancerous cells allowing us to more accurately remove affected areas.<\/p>\n<p>I am also hopeful that St George\u2019s Hospital, Tooting, pioneering use of robotic surgery in urology will be expanded to include maxillofacial procedures in the next year.<\/p>\n<p>This, of course, requires considerable training and the challenge for surgeons is finding both the time and technological appetite for more study. It\u2019s always demanding working on the edge of your comfort zone, but that\u2019s where the real change takes place.<\/p>\n<p><em>Kavin Andi is a consultant maxillofacial and specialist microvascular reconstructive plastic surgeon at St George\u2019s Hospital, Tooting, London.<\/em><\/p>\n<p>Competing interests: KA has nothing to disclose.<\/p>\n<p>Patient consent obtained.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Some of us are driven by personal conviction about our career choice while others succumb to the subtle and not to subtle influence of peer pressure or well meaning parents.
