Youri P A Tan, Philippe Liverneaux, Jason K F Wong
Surgical robots have the potential to provide surgeons with increased capabilities, such as removing physiologic tremor, scaling motion and increasing manual dexterity. Several surgical specialties have subsequently integrated robotic surgery into common clinical practice. Plastic and reconstructive microsurgical procedures have not yet  benefitted significantly from technical developments observed over the last two decades. Several studies have successfully demonstrated the feasibility of utilising surgical robots in plastic surgery procedures, yet limited work has been done to identify and analyse current barriers that have prevented wide-scale adaptation of surgical robots for microsurgery...

This case report describes the novel use of transoral robotic surgery (TORS) with delayed transoral laser microsurgery (TLM) for residual disease in the resection of a pediatric neurofibroma with supraglottic and parapharyngeal space extension. Postoperatively, the patient had excellent functional outcomes. This case demonstrates that pediatric TORS is feasible, safe, and complementary to TLM. Neurofibroma is just one of the diverse pathologic processes of the pediatric airway that can be managed via transoral surgery, and applications of TORS with TLM will continue to broaden as our experience develops...

Men have most likely been affected by varicocele since the assumption of the upright position. In De Medicina, written during the first century AD, Celsus credits the Greeks with the first description of a varicocele, and he recorded his own acute observation: "The veins are swollen and twisted over the testicle, which becomes smaller". Celsus himself is credited with the distinction between varicocele (dilation of surface veins) and "cirsocele" (dilation of deep veins). There has been a long history of treatment attempts and failures, some of which are remarkably strange, that have sometimes culminated in tragedy, as in the case of French professor Jacques-Mathieu Delpech (1772- 1832)...

Marina Roizenblatt, Thomas L Edwards, Peter L Gehlbach
Vitreoretinal microsurgery is among the most technically challenging of the minimally invasive surgical techniques. Exceptional precision is required to operate on micron scale targets presented by the retina while also maneuvering in a tightly constrained and fragile workspace. These challenges are compounded by inherent limitations of the unassisted human hand with regard to dexterity, tremor and precision in positioning instruments. The limited human ability to visually resolve targets on the single-digit micron scale is a further limitation...

Maura Power, Alex J Thompson, Salzitsa Anastasova, Guang-Zhong Yang
Microscale robotic devices have myriad potential applications including drug delivery, biosensing, cell manipulation, and microsurgery. In this work, a tethered, 3D, compliant grasper with an integrated force sensor is presented, the entirety of which is fabricated on the tip of an optical fiber in a single-step process using 2-photon polymerization. This gripper can prove useful for the interrogation of biological microstructures such as alveoli, villi, or even individual cells. The position of the passively actuated grasper is controlled via micromanipulation of the optical fiber, and the microrobotic device measures approximately 100 µm in length and breadth...

Background: Robot-assisted surgery has revolutionized many surgical subspecialties, mainly where procedures have to be performed in confined, difficult to visualize spaces. Despite advances in general surgery and neurosurgery, in vivo application of robotics to ocular surgery is still in its infancy, owing to the particular complexities of microsurgery. The use of robotic assistance and feedback guidance on surgical maneuvers could improve the technical performance of expert surgeons during the initial phase of the learning curve...

Robot-assisted surgery is more and more widely used in urology, general surgery and gynecological surgery. The interest of robotics in plastic and reconstructive surgery, a discipline that operates primarily on surfaces, has yet to be conclusively proved. However, the initial applications of robotic surgery in plastic and reconstructive surgery have been emerging in a number of fields including transoral reconstruction of posterior oropharyngeal defects, nipple-sparing mastectomy with immediate breast reconstruction, microsurgery, muscle harvesting for pelvic reconstruction and coverage of the scalp or the extremities...

REVIEW
Özgül Topal
Open partial or total laryngectomies with or without radiotherapy (RT) or chemoradiotherapy (CRT) are the only mainstays in the treatment of laryngeal carcinomas. However, minimally invasive procedures such as transoral endoscopic carbondioxide laser microsurgery (TLM) or transoral robotic surgeries (TRS) are now being increasingly used in selected patients. The laryngeal framework is not disturbed in these procedures; therefore, the postoperative swallowing function improves more rapidly, and routine tracheotomy is not usually required...

Microsurgery is a technically demanding field with long learning curves. Robotic-assisted microsurgery has the ability to decrease these learning curves. We, therefore, sought to assess the feasibility of robotic-assisted microvascular surgery in a rat model, and whether this could be translated into a worthwhile skills acquisition exercise for residents. Twenty-eight rats underwent microvascular anastomosis. Procedures were performed by a trained microvascular surgeon with no robotic experience (n = 14), or a trained robotic surgeon with no microvascular experience (n = 14)...

Chronic orchialgia is one of the most common complaints seen in the urologists office and has traditionally been considered a very difficult diagnostic and therapeutic challenge for the clinician. First line management of chronic orchialgia is conservative treatment; however, in men who fail conservative therapy, surgical intervention may be indicated. Microsurgery has been the mainstay for surgical treatment of chronic orchialgia, but the implementation of robotics to microsurgery lends itself particularly to surgical treatment of chronic orchialgia...
