Effects of throat packs during orthognathic surgery: a double-blind randomized controlled clinical trial.

Throat packs are commonly used in maxillofacial surgeries. 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<0.001). There was no difference between the groups regarding postoperative nausea and vomiting (P=1.00). The results of this study indicate that throat packs as utilized here do not prevent postoperative nausea and vomiting and are associated with worse sore throats and postoperative dysphagia.
