There is increasing demand for surgical procedures which avoid visible scars while maintaining optimal functional and ideal cosmetic results, without compromising the safety or effectiveness of the procedure. Endoscopic techniques have been adapted to abdominal and pelvic surgery and increasingly employed over the past three decades. Although hampered by the absence of a natural cavity, endoscopic techniques have been adapted to surgery in the neck for the past 15 years, particularly for the thyroid gland. While earlier attempts at endoscopic thyroid surgery were performed through incisions in or near the midline of the neck, recent techniques have been developed to place the incisions and endoscopic ports extracervically, or at least away from the midline region of the neck, rendering the cosmetic result more acceptable. Most of these approaches are through the axilla, breast, chest wall or a combination of approaches. Visualization of the thyroid and rate of complications with these approaches are equal to those attained with older endoscopic approaches. Careful patient selection is important for endoscopic surgery. Complications unique to the endoscopic approach are mostly related to insufflation of cervical tissues with pressurized CO2.
