Filter by:Rhinoplasty is among the most accomplished aesthetic procedures in Plastic Surgery. The mastery of Alar Base modifications is essential for superior aesthetic results. The main indication is to reduce nasal width when it exceeds the intercanthal distance in Caucasian women. Other indications are the modification of the shape of the nostrils or to reduce alar flare in noses with too convex alar base. Since Wier's first description, a series of techniques has been developed with a common goal of making the basal view of the nose close to an equilateral triangle. The location and amount of tissue to be removed will be according to the preoperative or intraoperative indication due to changes in the alar base resulting from reductions in the projection of the nasal tip. One of the controversies in the literature is in the position of the incision in alar base modifications. Some authors prioritize incisions that do not violate the alar facial groove , since the groove region presents a greater number of sebaceous glands, leading to poor scarring results. Other authors have argued that incisions above the sulcus have caused more evident scars, anda that poor healing results would be more associated with aggressive resections of border and bad closing skin techniques. Due to divergence in the literature, the present study aims to compare, through a double blinded randomized clinical trial, two techniques of alar base modifications that will differentiate only by violating or not the alar facial groove.
Posterior wall osteotomy would be conducted to manage the old acetabular fracture. The outcome was reviewed to assess the feasibility of the surgical procedure.
CONTEXT AND AIMS: The aim of the study is to compare patients satisfaction of thoracic epidural and general anesthesia procedures in patients undergoing elective laparoscopic cholecystectomy. SETTINGS AND DESIGN: This comparative randomized study was conducted Abant Izzet Baysal University hospital between October 2012 and 2014.Forty-five patients who were under American Society of Anesthesiologists I-II classification and were scheduled for elective laparoscopic cholecystectomy were included in the study. SUBJECTS AND METHODS: All participant was separated, two group. In epidural anesthesia group(Group E), a catheter was installed and received 20 mg lidocaine hydrochloride, 15 mg bupivacaine, and 25 mg fentanyl citrate adjusted to 10 cc with normal saline to be injected by the epidural catheter. Bispectral index -controlled sedation was provided. In general anesthesia group(Group G), and induction was managed using 1.5 mg/kg fentanyl and 2 mg/kg propofol; 0.5 mg/kg rocuronium and sevoflurane in a 50% oxygen/air mixture was used. Blood gas analysis monitoring was performed in the 30th minute before and after pneumoperitoneum. Surgical satisfaction was recorded after pneumoperitoneum. After the operation, 75 mg diclofenac sodium was applied for patients with Numeric Rating Scale scores higher than 4. STATISTICAL ANALYSIS USED:Data analysis was performed using the Statistical Package for the Social Sciences version 18 software (SPSS, Chicago, IL, US). Descriptive variables, such as age, ASA classification, weight, height, mean arterial pressure (MAP), HR, and duration of surgery, are given as mean ± standard deviation, and an independent sample t-test (normal distribution) as well as a Mann-Whitney U test (not a normal distribution) were used for continuous variables. To compare the normal and abnormal distributions in the groups, simple t-test, and Wilcoxon test was used, respectively. The results were considered statistically significant at p-values <0.05.
The purpose of this study is to evaluate safety and efficacy of corneal cross-linking and photorefractive keratectomy for refractive correction in patients with bilateral asymmetric topography.
This is a prospective randomized study involving 80 patients. All participates will be given written information on 3D laparoscopy. They will be randomized according to computer-generated random sequence into two groups, 2D and 3D group. The operation will then be performed either using 2D or 3D laparoscopy. Surgeons are allowed to change to the other type of laparoscopy if difficulty encountered. After the operation, the surgeons will be required to fill in a questionnaire self-evaluating the performance using Global rating scale component of the intraoperative assessment tool (GOALS), any discomfort encountered, any need for change of laparoscopy and their preference on the type of laparoscopy. The level of complexity of the operation, duration of operation, blood loss and complications will be recorded.
This study will compare two commonly-used methods for assessing patient-reported quality of life. The first is to assess quality of life before surgery and again after surgery using the same validated scale (ie Veterans Rand 12). The second is simply to ask patients whether or not they think their post-operative quality of life is better, worse, or the same. The investigators hypothesize that the second method may be inaccurate due to cognitive bias.
The purpose of this study is to compare difference of displacement between Polyvinyl Chloride(PVC) and Silicon double-lumen endobronchial tubes(DLTs) during changing position from supine to lateral in thoracic surgery.
This is a multicentre, prospective, observational cohort study. Consecutive patients, operated in six University Hospitals in Sweden will be recruited following major surgical procedure. The length of patient recruitment period will be 12 weeks. The length of follow up will be 360 days . The objectives are to determine the postoperative morbidity (during the hospital stay), the survival (0-360 days), to identify risk factors for adverse outcomes and to identify risk factors that may potentially be influenced by any intervention in the future. Amendments: 1. The follow-up of mortality is extended to 3 years of the cohort 2. The mortality of the background population at 30 and 90 Days will be analyzed 3. Validation of the Surgical Outcome Risk Tool in the study cohort and in the background population are planned
Evaluation of Topical and Intravenous Tranexamic Acid in Surgical Treatment of Lumbar Degenerative Disease
Failure to recognise deterioration early is a major cause of preventable deaths amongst hospital patients. The investigators wish to study whether continuous monitoring of 'vital signs' (pulse rate, breathing rate, and blood oxygen saturations) with computer modeled alerting to detect patient deteriorations can reduce cardiac arrest rate and critical care readmissions from the wards by alerting staff to clinical deteriorations more effectively than current paperbased systems. Continuous monitoring of 'vital signs' can be achieved in two ways. Continuous monitoring of 'vital signs' has traditionally been restricted to the bedside because of the need for the patient to be connected by wires to the monitor. More recently, advances in telemetry (wireless technology) have allowed the development of wearable devices which allow patients to mobilise freely, whilst constantly monitoring these 'vital signs'.
