In this paper, we propose an augmented reality (AR) assisted sinus surgery system, in which the surgical outcome is improved by providing a new way of visualization which embeds virtual environments into the real scene. Such an AR assisted system, with a preoperative CT scan registered and displayed throughout the surgery, would provide the surgeon visibility of the nearby structures surroundin...

A trend in abdominal surgery is the transition from open procedures to minimally invasive laparoscopic interventions, where visual feedback to surgical staff is only available through the laparoscope camera and direct palpation of organs is impossible. To successfully perform such sophisticated interventions, the provision of additional intraoperative feedback can be of great help to the surgic...

One of the recent design goals in Human Computer Interaction has been to extend the sensorymotor capabilities of computer systems to combine the real and the virtual in order to assist the user in his environment. Such systems are called Augmented Reality (AR). Although AR systems are becoming more prevalent we still do not have a clear understanding of this interaction paradigm. In this paper ...

In this case series study, we assessed the effects of recession-resection surgery augmented with botulinum toxin A chemodenervation for patients with chronic paralytic horizontal strabismus. In addition, we compared these effects with those of full tendon transposition (FTT) augmented with posterior intermuscular suture (PIMS). Ten patients who underwent strabismus surgery due to paralytic hori...

BACKGROUND Initial overcorrection after exotropia surgery has been considered as a desirable result. Recently, there had been several studies that reported better surgical results of augmented bilateral lateral rectus muscle recession procedure over the conventional procedure. OBJECTIVES To compare the long-term results of augmented unilateral lateral rectus recession-medial rectus resection ...
