Background and Objectives: The implementation of intraoperative imaging in the procedures performed under the guidance of the same finds its history dating back to the early 1990s. This practice was abandoned due to many deficits and practicality. Later, fluoroscopy-dependent techniques were developed and have been used even in the present time, albeit with several disadvantages. With the recent advancement of several complex surgical techniques, which demand higher accuracy and are in conjunction with the existence of radiation exposure hazard, C-arm-free techniques were introduced. In this review study, we aim to demonstrate the various types of these techniques performed in our hospital. Materials and Methods: We have retrospectively analyzed and collected imaging data of C-arm-free, minimally invasive techniques performed in our hospital. The basic steps of the procedures are described, following with a discussion, along with the literature of findings, enlisting the merits and demerits. Results: MIS techniques of the thoracolumbar and lumbar spine that do not require the use of the C-arm can offer excellent results with high precision. However, several disadvantages may prevail in certain circumstances such as the navigation accuracy problem where in the possibility of perioperative complications comes a high morbidity rate. Conclusions: The accustomedness of performing these techniques requires a steep learning curve. The increase in accuracy and the decrease in radiation exposure in complex spinal surgery can overcome the burden hazards and can prove to be cost-effective. Full article

Repeated exposure to aesthetic design results in consumers experiencing satiation because of sensory satiety. In other words, being consistently exposed to aesthetic stimuli activates consumers’ sensory satiety, defined as the drop in sensory pleasure, and the resulting reduction of their value of aesthetic products ultimately leads to switching intentions. That is, sensory satiety reduces functional and emotional benefits. Furthermore, consumers are unlikely to recall every item they have consumed, and are instead likely to focus on a particular option. Thus, this study predicts that consumers can recover from satiation over time. This research proposes that both satiation and accustomedness negatively affect functional benefit. As an empirical study, the research uses a multiple regression model for two purposes: The first is to test the impact of sensory satiety on perceived benefits, and the second is to observe the change in sensory satiety over time. We find that satiation and accustomedness, as sub-dimensional scales of sensory satiety, reduce perceived benefits. The results showed that it is clear that only satiation reduced functional benefits, whereas both satiation and accustomedness reduced emotional benefits. In addition, our study confirms the change in sensory satiety over time. Consumers who have been continuously exposed to, and used, aesthetic products become accustomed to them and feel satiated. Based on these results, this study will be useful for the sustainability of the product life cycle. Full article
