Topical analgesia for acute otitis media

Area of Science:

• Otolaryngology
• Pain Management
• Evidence-Based Medicine

Background:

• Acute otitis media (AOM) is a common childhood illness characterized by significant pain.
• Antibiotic efficacy for AOM is increasingly questioned, prompting research into alternative treatments.
• Topical analgesia offers a potential non-systemic approach to managing AOM-related pain.

Purpose of the Study:

• To evaluate the effectiveness of topical analgesic ear drops for pain relief in acute otitis media.
• To synthesize findings from randomized controlled trials comparing analgesic ear drops with placebo or other treatments.

Main Methods:

• A systematic search of multiple databases (CENTRAL, MEDLINE, EMBASE, LILACS) was conducted.
• Inclusion criteria focused on double-blind randomized controlled trials of otic preparations with analgesic effects (excluding antibiotics) in AOM patients without perforation.
• Data extraction and quality assessment were performed independently by multiple authors.

Main Results:

• Four trials met the inclusion criteria, involving a total of 328 participants.
• One trial showed a 25% pain reduction with anesthetic ear drops compared to placebo at 30 minutes.
• Three trials comparing anesthetic drops with naturopathic herbal drops favored the herbal preparation in pain reduction.

Conclusions:

• The current evidence from four randomized controlled trials is insufficient to determine the effectiveness of topical analgesic ear drops for AOM.
• Further high-quality research is needed, particularly addressing the primary effectiveness of analgesic preparations.
