Open surgery revealed a better long-term survival rate than the hybrid procedure at 5 and 10 years surgical, 82%, 65.7%; hybrid, 53%, 35.1%, respectively (p=0.0452). The rate of freedom from aortic events was significantly better with open surgery than a hybrid procedure at 5 and 10 years surgical, 96%, 85%; hybrid, 83%, 41.3%, respectively (p=0.0082). Surgery for an entire shaggy aorta was frequently associated with embolic complications such as stroke, paraplegia, renal failure, and bowel necrosis. However, open surgical repair may produce better early and late outcomes and freedom from aortic events compared with hybrid repair.

However, the evidence to support the benefits of their use is controversial. The aim of this study was to evaluate the effectiveness of throat packs in preventing postoperative nausea and vomiting, and their influence on the incidence of sore throat and dysphagia in patients undergoing orthognathic surgery. This was a prospective double-blind randomized study with 54 patients, who were randomized to two groups with throat pack (n=27) and without throat pack (n=27). Fifty patients (25 in each group) were included in the analysis; 66% female and 34% male, mean age 29.44±8.53 years. Postoperative nausea and vomiting (Kortilla scale), sore throat (visual analogue scale), and dysphagia were evaluated. Statistically significant differences in favour of the without-pack group were found for the variables throat pain at 24hours (P=0.002) and dysphagia at 2 hours (P=0.007) and 24 hours (P less then 0.001). There was no difference between the groups reg
