    Abstract:
    OBJECTIVE: No study to date has assessed the anti-adhesive effect of new middle ear (ME) packing agents in. This study compared the anti-inflammatory and anti-adhesive effect of antibiotic-steroid containing packing agents in abraded mucosa of the ME inflammation. MATERIALS AND METHODS: Transbullar injection of a saline suspension of Pseudomonas aeruginosa lipopolysaccharide (LPS) induced otitis media. ME mucosa of guinea pigs was abraded using a pick 30 min after LPS inoculation. The animals were divided into four groups of 10 guinea pigs each. In group A, ME cavity was preserved without any packing. In group B, ME cavity was packed with soluble hyaluronic acid-carboxymethyl cellulose (HA-CMC). In group C, the ME cavity was packed with soluble HA-CMC. In group D, the ME cavity was packed with antibiotic-steroid containing soluble HA-CMC. Otoendoscopic examination, auditory brainstem responses (ABRs), and radiographic examination using computerized tomography (CT) were performed at 2 weeks post-surgery. Histopathological evaluation for ME mucosa was performed by light microscopy (LM) and scanning electron microscopy (SEM). RESULTS: Otoendoscopic findings and CT findings revealed that group D showed the best recovery of aeration in the ME compared to other groups. Recovery of ABRs threshold was significantly attenuated in group D. In LM and SEM findings, group D showed normalized mucosal thickening compared to other groups. CONCLUSION: ME packing by antibiotic-steroid containing soluble HA-CMC may be useful in the abraded mucosa of the ME inflammation.
