The Effects of Music Therapy in Patients Undergoing Septorhinoplasty Surgery Under General Anesthesia

INTRODUCTION: Music has been used for several years as a relaxation method to reduce stress and anxiety. It is a painless, safe, inexpensive and practical nonpharmacologic therapeutic modality, widely used all over the world. OBJECTIVES: We aimed to evaluate the effect of music therapy on intraoperative awareness, patient satisfaction, awakening pain and waking quality in patients undergoing elective septorhinoplasty under general anesthesia. METHODS: This randomized, controlled, prospective study was conducted with 120 patients undergoing septorhinoplasty within a 2 months period. The patients were randomly selected and divided into two groups: group music (music during surgery) and control group (without music during surgery). All patients underwent standard general anesthesia. Patients aged 18-70 years who would undergo a planned surgery under general anesthesia were included. Patients who had emergency surgery, hearing or cognitive impairment, were excluded from the study. RESULTS: A total of 120 patients were enrolled, and separated into two groups. There were no statistically significant differences between the groups in terms of demographic characteristics, anesthesia and surgery durations (p\u3e0.05). In the music group, sedation agitation scores were lower than those in the control group at the postoperative period (3.76±1.64 vs. 5.11±2.13; p\u3c0.001). In addition; in patients of the music group, the pain level (2.73±1.28 vs. 3.61±1.40) was lower (p\u3c0.001), requiring less analgesic drugs intake. CONCLUSION: Music therapy, which is a nonpharmacologic intervention, is an effective method, without side effects, leading to positive effects in the awakening, hemodynamic parameters and analgesic requirements in the postoperative period. It is also effective in reducing the anxiety and intraoperative awareness episodes of surgical patients

Influence of Cavity Design on Stress Distribution in Second Premolar Tooth Using Finite Element Analysis

The objective of this study is, using finite element analysis, to design cavity geometry, to minimize risk of the fraction and cracking in second premolar tooth. To avoid possible tooth fracture, proper cavity geometry can be designed, to reduce the effect of masticatory forces. Premolar tooth was chosen due to its least strength in comparison to other type of teeth. In literature, there was insufficient study on using finite elements methods to investigate restorated premolar teeth. A healthy premolar tooth was scanned to obtain 3D model of it, to perform finite elements analysis. The validation was performed based on existing experimental data. According to stress distribution, three different cavity geometries were designed using composite resin and ceramic as a restoration material. It is observed that the amount of stress acting on tooth is diminishable with regard to analysis results. Hence, proper cavity geometry and material were found to minimize the risk of tooth fracture
