Xiaojun Chen, Lu Xu, Xing Li, Jan Egger
Patient-specific cranial implants are important and necessary in the surgery of cranial defect restoration. However, traditional methods of manual design of cranial implants are complicated and time-consuming. Our purpose is to develop a novel software named EasyCrania to design the cranial implants conveniently and efficiently. The process can be divided into five steps, which are mirroring model, clipping surface, surface fitting, the generation of the initial implant and the generation of the final implant...

INTRODUCTION: The widespread adoption of laparoscopic surgery has put new physical demands on the surgeon leading to increased musculoskeletal disorders and injuries. Shoulder, back, and neck pains are among the most common complaints experienced by laparoscopic surgeons. Here, we evaluate the feasibility and efficacy of a non-intrusive progressive arm support exosuit worn by surgeons under the sterile gown to reduce pain and fatigue during surgery. METHODS AND PROCEDURES: This is a prospective randomized crossover study approved by the Internal Review Board (IRB)...

BACKGROUND: Previous studies have shown that the nasal passage plays an important role in manual face mask ventilation, but this has yet to be quantitatively assessed. We conducted a prospective randomized crossover clinical trial to compare the change in pressure-controlled face mask tidal volume with and without nasal airway occlusion. METHOD: Female patients undergoing elective surgery under general anesthesia served as study subjects. Patients were randomly assigned to face mask ventilation beginning either with or without nasal passage occlusion (achieved with a swimmer's nose clip), followed by removal or application of the nose clip, respectively...

Insulinoma is the most common functioning islet cell tumor of the pancreas, with an annual incidence of 4 cases/1 million individuals. It is treated by surgical methods. Open surgery was once considered the standard approach for the treatment of insulinoma. However, the procedure is traumatic and requires a large incision, which does not satisfy the growing expectations of minimally invasive management of small-sized tumors. Insulinomas are usually benign solitary tumors and mostly occur sporadically, which makes them suitable candidates for laparoscopic management...

PURPOSE: Epilepsy is potentially curable with resective surgery if the epileptogenic zone (EZ) can be identified. If non-invasive imaging is unable to elucidate the EZ, intracranial electrodes may be implanted to identify the EZ as well as map cortical function. In current clinical practice, each electrode trajectory is determined by time-consuming manual inspection of preoperative imaging to find a path that avoids blood vessels while traversing appropriate deep and superficial regions of interest (ROIs)...

Acoustic neuroma surgery is a procedure in which a benign mass is removed from the internal auditory canal (IAC). Currently, this surgical procedure requires manual drilling of the temporal bone followed by exposure and removal of the acoustic neuroma. This procedure is physically and mentally taxing to the surgeon. Our group is working on the development of an acoustic neuroma surgery robot (ANSR) to perform the initial drilling procedure. Planning the ANSR's drilling region using preoperative CT requires expertise and takes about 35 min...

BACKGROUND: Pancreatic texture is one of the key predictors of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). Currently, the "gold standard" for assessment of pancreatic texture is surgeon's subjective evaluation through manual palpation. AIM: To evaluate a new "durometer" that is able to assess quantitatively the pancreatic stiffness by measuring its elastic module (i.e., the resistance offered by the pancreatic stump when elastically deformed expressed in mPa)...

BACKGROUND: Modern signed languages of the deaf are fully expressive, natural human languages that are perceived visually and produced manually.The literature contains little data concerning human brain organization in conditions of deficient sensory information such as deafness. CASE DESCRIPTION: Here, we describe an original case of a deaf-mute patient with a left temporo-insular low-grade glioma that was operated. The patient underwent awake surgery with intraoperative electrical stimulation mapping, allowing for the first time in the literature, to directly study the cortical and subcortical organization of signed language...

The management of severe keratoconus requires corneal transplantation, for which the gold standard is deep anterior lamellar keratoplasty (DALK), preserving the healthy Descemet's membrane and endothelium. The safety and reproducibility of corneal cuts have been improved by the evolution of femtosecond lasers in refractive surgery, and femtosecond laser in DALK would seem to provide the same advantages over the manual method. In our retrospective study, we compare functional and anatomical results of femtosecond-assisted DALK versus manual trephination DALK in patients with keratoconus in stage 4 of the Krumeich classification...

The placenta accreta spectrum (PAS) is a complex obstetric complication associated with a high maternal morbidity. It is a relatively new disorder of placentation, and is the consequence of damage to the endometrium-myometrial interface of the uterine wall. When first described 80 years ago, it mainly occurred after manual removal of the placenta, uterine curettage or endometritis. Superficial damage leads primarily to an abnormally adherent placenta, and is diagnosed as the complete or partial absence of the decidua on histology...

BACKGROUND: Having one hand occupied with the endoscope is the major disadvantage for the surgeon when it comes to functional endoscopic sinus surgery (FESS). Only the other hand is free to use the surgical instruments. Tiredness or frequent instrument changes can thus lead to shaky endoscopic images. METHODS: We collected the pose data (position and orientation) of the rigid 0° endoscope and all the instruments used in 16 FESS procedures with manual endoscope guidance as well as robot-assisted endoscope guidance...

BACKGROUND AND OBJECTIVES: Measurements of the cyclotorsional movement of the eye are crucial in refractive surgery procedures. The planned surgery pattern may vary substantially during an operation because of the position and eye movements of the patient. Since these factors affect the outcome of an operation, eye registration methods are applied in order to compensate for errors. While the majority of applications are based on features of the iris, we propose a registration method which uses scleral blood vessels...
