Abstract
Objectives: To evaluate the effectiveness of ofloxacin ear drops versus no intervention in the repair of traumatic tympanic membrane (TM) perforations from randomized controlled trials (RCTs). Data Sources: Medline/PubMed, CENTRAL, Clinical Trials.Gov, and Google Scholar. Study Selection: Inclusion criteria: (1) English language; (2) RCT studies; (3) reported the outcomes on the application of ofloxacin and outcomes of spontaneous healing. Exclusion criteria: (1) studies without a control group; (2) patient with severe otologic disease such as chronic suppurative otitis media or ossicular disruption or patients with craniocerebral injury; (3) studies with no pretreatment values or single-arm clinical studies. Data Extraction: Country, year of publication, number of participants in each arm, patient characteristics such as age, sex, intervention details, laterality, cause of TM perforation, position of perforation, follow-up time, hearing gain, rate of TM closure, and closure time. Results: A total of 6 RCTs studies were analyzed. A total of 502 participants were included; the relative risk for closure rate of ofloxacin treatment was 1.18 [95% confidence interval (CI), 1.08 to 1.28, P < .001] and the mean difference (MD) for healing time was -18.4 (95% CI, -19.96 to -16.82, P < .001), suggesting ofloxacin has a significant effect on closure of TM perforations. However, no clinically significant effect in hearing (SMD: 0.21, 95% CI, 0.02 to 0.40, P = .03) was seen in ofloxacin group. Also, patients in the ofloxacin group were associated with a 13% reduction in the risk of infections compared to their observation-assigned counterparts, but this estimate was not statistically significant. Conclusion: Ofloxacin use in patients with traumatic TM perforation is effective in reducing healing time and increasing rate of TM perforation closure. No evidence of increased risk of hearing loss or infection rates are encountered when ofloxacin is prescribed to patients with traumatic TM perforation.

Collagen Matrix to Restore the Tympanic Membrane: Developing a Novel Platform to Treat Perforations. Polymers (Basel) 2024; 16:248.

Abstract
Modern otology faces challenges in treating tympanic membrane (TM) perforations. Instead of surgical intervention, alternative treatments using biomaterials are emerging. Recently, we developed a robust collagen membrane using semipermeable barrier-assisted electrophoretic deposition (SBA-EPD). In this study, a collagen graft shaped like a sponge through SBA-EPD was used to treat acute and chronic TM perforations in a chinchilla model. A total of 24 ears from 12 adult male chinchillas were used in the study. They were organized into four groups. The first two groups had acute TM perforations and the last two had chronic TM perforations. We used the first and third groups as controls, meaning they did not receive the implant treatment. The second and fourth groups, however, were treated with the collagen graft implant. Otoscopic assessments were conducted on days 14 and 35, with histological evaluations and TM vibrational studies performed on day 35. The groups treated with the collagen graft showed fewer inflammatory changes, improved structural recovery, and nearly normal TM vibrational properties compared to the controls. The porous collagen scaffold successfully enhanced TM regeneration, showing high biocompatibility and biodegradation potential. These findings could pave the way for clinical trials and present a new approach for treating TM perforations.

Abstract
Perforation is the most common illness of the tympanic membrane (TM), which is commonly treated with surgical procedures. The success rate of the treatment could be improved by novel bioengineering approaches. In fact, a successful restoration of a damaged TM needs a supporting biomaterial or scaffold able to meet mechano-acoustic properties similar to those of the native TM, along with optimal biocompatibility. Traditionally, a large number of biological-based materials, including paper, silk, Gelfoam®, hyaluronic acid, collagen, and chitosan, have been used for TM repair. A novel biopolymer with promising features for tissue engineering applications is cellulose. It is a highly biocompatible, mechanically and chemically strong polysaccharide, abundant in the environment, with the ability to promote cellular growth and differentiation. Bacterial cellulose (BC), in particular, is produced by microorganisms as a nanofibrous three-dimensional structure of highly pure cellulose, which has thus become a popular graft material for wound healing due to a number of remarkable properties, such as water retention, elasticity, mechanical strength, thermal stability, and transparency. This review paper provides a comprehensive overview of the current experimental studies of BC, focusing on the application of BC patches in the treatment of TM perforations. In addition, computational approaches to model cellulose and TM are summarized, with the aim to synergize the available tools toward the best design and exploitation of BC patches and scaffolds for TM repair and regeneration.
