Antibiotic prophylaxis in clean and clean-contaminated ear surgery

Area of Science:

• Otolaryngology
• Infectious Disease Prevention
• Surgical Outcomes

Background:

• Ear surgery addresses conditions like chronic otitis media and tympanic membrane perforations.
• Postoperative complications include wound infections, middle ear infections, graft failure, and labyrinthitis.
• These complications increase patient morbidity and healthcare costs.

Purpose of the Study:

• To evaluate the efficacy of local and/or systemic antibiotics in preventing complications after clean or clean-contaminated ear surgery.
• Key complications assessed were postoperative discharge, graft failure, and labyrinthitis.

Main Methods:

• A systematic review of randomized or quasi-randomized trials was conducted.
• Searches included major databases (MEDLINE, EMBASE, CENTRAL) up to December 2002.
• Eleven studies were included, with data extracted and quality assessed by two independent reviewers.

Main Results:

• No significant differences were found between antibiotic prophylaxis and control groups.
• Antibiotics did not reduce postoperative infections, graft failures, or draining outer ear canals.
• Adverse drug effects were also not significantly different between groups.

Conclusions:

• There is insufficient evidence to support the routine use of prophylactic antibiotics in clean and clean-contaminated ear surgery.
• Current evidence does not demonstrate a benefit in reducing common postoperative complications.
• Further research may be needed to clarify the role of antibiotic prophylaxis.
