Robotic surgery has become the standard of care for many procedures outside of otolaryngology and now is gaining momentum within our specialty. The da Vinci (Intuitive Surgical, Sunnyvale, CA) robot has several advantages to human hands, including removal of tremor and better access to lesions because of increased degree of movement of the articulated instruments. The glottis has rarely been addressed using robotic surgery because access was previously thought to be difficult because of the limitations of currently used retractors, which include poor base of tongue and oral commissure retraction resulting in lack of exposure of the glottis in many patients and lack of space for the robotic instruments to occupy...

INTRODUCTION: Modifications of the temporomandibular joint position after mandible osteotomy are reluctantly accepted in orthognathic surgery. To tackle this problem, we developed a new navigation system using miniaturized electromagnetic sensors. Our imageless navigation approach is therefore optimized to avoid complications of previously proposed optical approaches such as the interference with established surgical procedures and the line of sight problem. MATERIAL AND METHODS: High oblique sagittal split osteotomies were performed on 6 plastic skull mandibles in a laboratory under conditions comparable to the operating theatre...

STUDY OBJECTIVE: To demonstrate a new approach for orthotopic human ovarian tissue transplantation via robot-assisted laparoscopic surgery. DESIGN: A step-by-step video explanation of the surgical technique (Canadian Task Force Classification-III). SETTING: Although still experimental, cryopreservation and subsequent transplantation of frozen-thawed ovarian tissue is currently the only available method for prepubertal girls and young women with cancer who are not eligible for established fertility preservation options such as the oocyte or embryo cryopreservation (1)...

J F Hamming, P J Marang-van de Mheen
All abdominal surgical procedures have a certain risk/benefit ratio. Recently, the way surgeons come to a decision whether to operate, or not, was discussed in the Annals of Surgery. First, the assessment of the decision for an operative versus a non-operative strategy was addressed on the basis of clinical vignettes. The perceptions concerning risk/benefit balance varied considerably between surgeons and these perceptions predicted the decision to operate. In a second paper, surgeons were randomized to either an arm in which they were exposed to a risk calculator or to a control arm...

Surgery using a robotic system has proven to have significant potential but is still a highly challenging task for the surgeon. An eye surgery assistant has been developed to eliminate the problem of tremor caused by human motions endangering the outcome of ophthalmic surgery. In order to exploit the full potential of the robot and improve the workflow of the surgeon, providing the ability to change control parameters live in the system as well as the ability to connect additional ancillary systems is necessary...

The field of insertable laparoscopic robotic camera is gaining increasing attentions from researchers, surgeons, and also patients. Although many insertable laparoscope prototypes have been introduced, few of them get rid of the encumbrance tethering cable. In this paper, we proposed a hardware architecture for a magnetic actuated robotic surgical (MARS) camera, which facilitates a cable-free fully insertable laparoscopic surgical robotic camera with adequate in-vivo mobility. Modular design and preliminary test of on-board functional payloads have shown feasibility of a cable-free insertable wireless laparoscopic surgical camera based on off-the-shelf electronics and industrial wireless standards operating in ISM frequency bands at 2...

The use of intraoperative MR and direct DBS targeting, relies on anatomical rather than functional data. Historical clinical outcome databases that have recorded stimulation location and magnitude of effect, can provide a useful adjunct in DBS targeting strategies. We present a method for generating clinical outcome topographies, and merging regions of effect onto a pre-operative MR, for surgical planning. The clinical outcome topographies are consistent with more intuitive strategies used by neurosurgeons...

Epileptic spike is an indicator of hyper-excitability and hyper-synchrony in the neural networks. The inhibitory effects of spikes on theta rhythms (4-8 Hz) might be helpful to understand the mechanism of epileptic damage on the cognitive functions. To quantitatively evaluate the inhibitory effects of spikes on theta rhythms, intracerebral electroencephalogram (EEG) recordings with both sporadic spikes (SSs) and spike-free transient period between adjacent spikes were selected in 4 patients in the status of rapid eyes movement (REM) sleep with temporal lobe epilepsy (TLE) under the pre-surgical monitoring...

BACKGROUND: Robotic surgery for rectal resection presents some advantages compared with the traditional technique; however, it also presents some limitations, especially due to the multiple changes of surgical fields. We describe a new technique to perform low-anterior resection using single docking with the rotation of the third arm and our perioperative results. MATERIALS AND METHODS: A total of 31 patients who underwent low-anterior rectal robotic resection with single-docking technique using robotic daVinci SI (Surgical Intuitive System) were included in the study...

BACKGROUND: Since the inception of robotic mitral valve repair (MV) in 2007 at our institution, it has become an acceptable surgical option with proven efficacy and safety. The objective of this study is to analyze the early and long-term clinical outcomes of patients undergoing robotic MV repair. METHODS: A total of 310 patients (aged 48.4±13.7 years, 201 males) undergoing robotic MV repair using the da Vinci system (Intuitive Surgical, Inc., Sunnyvale, CA) between August 2007 and December 2015 in our institution were evaluated...

BACKGROUND: In the past two decades, the introduction of robotic technology has facilitated minimally invasive cardiac surgery, allowing surgeons to operate endoscopically rather than through a median sternotomy. This approach has facilitated procedures for several structural heart conditions, including mitral valve repair, atrial septal defect closure and multivessel minimally invasive coronary artery bypass grafting. In this rapidly evolving field, we review the status of robotic cardiac surgery in Europe with a focus on mitral valve surgery and coronary revascularization...

Critical illness increases the probability of a neurologic complication. There are many reasons to consult a neurologist in a critically ill patient and most often it is altered alertness with no intuitive plausible explanation. Other common clinical neurologic problems facing the intensive care specialist and consulting neurologist in everyday decisions are coma following prolonged cardiovascular surgery, newly perceived motor asymmetry, seizures or other abnormal movements, and generalized muscle weakness...

REVIEW

BACKGROUND: Endoscopic sphenopalatine artery ligation is widely accepted as effective and safe for acute spontaneous epistaxis that is unresponsive to conservative management. As with many new procedures, it has been progressively adopted as common practice, despite a limited evidence base for its efficacy. Early reviews called for comparative trials to support its adoption, but subsequent literature largely consists of case series and narrative reviews. These have attempted to derive an algorithm to establish its place in management, but consensus is still lacking...

Transoral thyroid surgery allows the surgeon to conceal incisions within the oral cavity without significantly increasing the amount of required dissection. TORT provides an ideal scarless, midline access to the thyroid gland and bilateral central neck compartments. This approach, however, presents multiple technical challenges. Herein, we present our experience using the latest generation robotic surgical system to accomplish transoral robotic thyroidectomy (TORT). In two human cadavers, the da Vinci Xi surgical system (Intuitive Surgical, Sunnyvale, CA, USA) was used to complete TORT...

BACKGROUND: Utilization of the robotic approach to pyeloplasty continues to grow in the field of pediatric urology. Adoption in the infant population has perhaps been the slowest because of the limited operative domain and relatively large instruments. METHOD: In this video, we demonstrate key steps in performing an infant robotic pyeloplasty using the smallest instruments currently available for the da Vinci S and Si systems (Intuitive Surgical, Sunnyvale, California)...

OBJECTIVE: Most trainees begin learning robotic minimally invasive surgery by performing inanimate practice tasks with clinical robots such as the Intuitive Surgical da Vinci. Expert surgeons are commonly asked to evaluate these performances using standardized five-point rating scales, but doing such ratings is time consuming, tedious, and somewhat subjective. This article presents an automatic skill evaluation system that analyzes only the contact force with the task materials, the broad-bandwidth accelerations of the robotic instruments and camera, and the task completion time...
