The estimation of material properties is important for scene understanding, with many applications in vision, robotics, and structural engineering. This paper connects fundamentals of vibration mechanics with computer vision techniques in order to infer material properties from small, often imperceptible motion in video. Objects tend to vibrate in a set of preferred modes. The frequencies of these modes depend on the structure and material properties of an object. We show that by extracting these frequencies from video of a vibrating object, we can often make inferences about that object's material properties...

Trans-oral laporascopic thyroidectomy is a innovative technique that incoporated the concept of natural orifice transluminal endoscopic surgery. Compare to other endoscopic thyroidectomy, trans-oral laporascopic thyroidectomy is characterised with no scar in the body surface, better cosmetic results and conforms to the concept of minimally invasive surgery. At present, trans-oral laporascopic thyroidectomy is still in the initial stages of clinical application and gains a great deal of attention from surgeons all over the world...

The majority of head and neck cancers arise from the oral cavity and oropharynx. Many of these lesions will be amenable to surgical resection using transoral approaches including transoral robotic surgery (TORS). To develop and control TORS tools, precise dimensions of the oral cavity and pharynx are desirable. CT angiograms of 76 patients were analyzed. For the oral cavity, only the maximum length and width were measured, while for the pharynx, the width, length, and areas of the airway were all measured and the volume calculated...

In the current era of the early diagnosis of prostate cancer (PCa) and the development of minimally invasive surgical techniques, erectile dysfunction (ED) represents an important issue, with up to 68% of patients who undergo radical prostatectomy (RP) complaining of postoperative erectile function (EF) impairment. In this context, it is crucial to comprehensively consider all factors possibly associated with the prevention of post-RP ED throughout the entire clinical management of PCa patients. A careful assessment of both oncological and functional baseline characteristics should be carried out for each patient preoperatively...

OBJECTIVES/HYPOTHESIS: Transoral surgery (TOS) is commonly performed in a supine patient with an oral retractor. Paradoxically, this strategy can create difficulty with visualizing and accessing pathology at the base of tongue, inferior pharynx, and larynx. We investigate the feasibility of TOS with the patient in the seated position. STUDY DESIGN: Pilot study. METHODS: TOS utilizing the da Vinci Robotic Surgical Xi and Si systems (Intuitive Surgical, Sunnyvale, CA) was performed on a fresh cadaver placed in both the traditional supine position and the seated position...

OBJECTIVE: In Robot-assisted radical prostatectomy (RARP) patients, preoperative bowel preparation and intraoperative fluid restriction may cause dehydration and electrolyte imbalance. In these patients, laboratory results that are considered "normal" in the pre-anaesthesia clinic may be misleading, and cardiac arrhythmia due to hypokalaemia and hypocalcaemia, as well as problems, such as prolonged non-depolarising blockade and delayed recovery from anaesthesia, may be observed during anaesthesia practice...

This study describes a novel exposure technique for base of tongue trans-oral robotic surgery (BOT TORS) and early experience with it. The technique discussed involves placement of a suture through the mobile tongue with distraction and suspension of the tongue to the operating table. TORS is then performed per previously described techniques. In our series, 13 patients with either benign or malignant mass lesions involving the tongue base were treated with TORS at a tertiary academic medical center. We reviewed the rates of adequate exposure, console time, adequacy of resection (in malignant cases), complication rates, and costs associated with this technique...

Coblation tongue surgery and Trans-oral robotic surgery (TORS) proved to be the most published therapeutical options for the treatment of patients affected by obstructive sleep apneas (OSAHS). A systematic review of the literature and an analysis of the data are presented. The mean rates of failure were 34.4 and 38.5 %, respectively in TORS and Coblation groups. Complications occurred in 21.3 % of the patients treated with TORS and in 8.4 % of the patients treated with Coblation surgery. TORS seems to give slightly better results, allowing a wider surgical view and a measurable, more consistent removal of lingual tissue...

The rapid improvement of next-generation sequencing performance now enables us to analyze huge sample sets with more than ten thousand specimens. However, DNA extraction can still be a limiting step in such metagenomic approaches. In this study, we analyzed human oral microbes to compare the performance of three DNA extraction methods: PowerSoil (a method widely used in this field), QIAsymphony (a robotics method), and a simple boiling method. Dental plaque was initially collected from three volunteers in the pilot study and then expanded to 12 volunteers in the follow-up study...

In Ivor Lewis operation, anastomosis site leakage is a critical complication. Interventional approach utilizing covered metal stent has been introduced for the management of this complication. This patient was diagnosed as esophageal cancer and underwent robot-assisted Ivor Lewis operation. Due to symptoms suggesting anastomosis site leakage, video-assisted thoracoscopic surgery exploration was performed without identification of gross leakage site. On esophagogastroduodenoscopy, anastomosis site leakage was detected and esophageal stent was placed...

Malignant sublingual gland neoplasms are rare, early-stage neoplasms presenting as painless non-ulcerated masses in the antero-lateral floor of the mouth. The majority of patients present with advanced disease, with symptoms of pain or anaesthesia of the tongue. Malignant minor salivary gland neoplasms are more common, the majority (>80%) of which present in the oral cavity, most frequently in the palatal area, as painless masses or as obstructive symptoms in the head and neck region. The most frequent pathologies are adenoid cystic carcinoma and mucoepidermoid carcinoma (>85%), with the majority presenting at an advanced stage (III/IV)...
