Summary

This study compares giving a single dose of antibiotics during rhinoplasty (nose surgery) versus a full course of antibiotics after surgery. The goal is to see if the single dose works just as well at preventing infections. Over 800 adults having nose surgery will take part, and researchers will track infection rates between the two groups.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
cephalexin or clindamycin (antibiotics)
What this could lead to
If successful, this could show that a single antibiotic dose during surgery is enough to prevent infections, reducing the need for post-surgery antibiotics.
What could go wrong
This is a large trial, but it only looks at infection rates in rhinoplasty. Results may not apply to other surgeries, and the best antibiotic approach may still depend on individual patient factors.
