Background:
Corticosteroids are widely used to treat voice change after thyroidectomy. In this study, we evaluated the effect of a single dose of intravenous dexamethasone after thyroidectomy using a metaanalysis.
Methods:
Relevant studies were identified by searching the following databases: Medline, Embase, and Cochrane through February 2017. We followed PRISMA guidelines. The following search terms were used: "thyroidectomy," "voice," "steroid." Random-effects models were used to estimate standardized mean differences (SMDs) and 95% confidence intervals.
Results:
Our search yielded one retrospective cohort study involving 122 thyroidectomy patients and 3 randomized controlled studies involving 242 thyroidectomy patients. The pooled SMD for voice quality after thyroidectomy was -0.80 (P < .05). Subgroup analysis showed significant voice quality change 1 day after administration of dexamethasone.
Conclusions:
Single-dose intravenous dexamethasone after thyroidectomy significantly improves subjective voice quality on day 1. The effect was not different significantly after day 1.
Level Of Evidence:
Level 2a.

Cable Subjected to Its Own Weight
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...
Quality Control
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
