The Effect of Using Ofloxacin Ear Drops in Traumatic Tympanic Membrane Healing: A Systematic Review and Meta-Analysis

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.

Alternative Wound Management: Translating Science into Practice

GENERAL PURPOSE

To present a scoping review of preclinical and clinical trial evidence supporting the efficacy and/or safety of major alternative wound care agents to summarize their effects on validated elements of wound bed preparation and wound management paradigms.

TARGET AUDIENCE

This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care.

LEARNING OBJECTIVES/OUTCOMES

After participating in this educational activity, the participant will:1. Differentiate the effectiveness of the topical wound care agents included in this review.2. Compare the preventive efficacy of intravenous agents administered to trauma and surgical patients.3. Select the effectiveness of products in this review that are left in place after surgical procedures.4. Identify an oral agent that can be helpful in mitigating the effects of COVID-19.

A Systematic Review of Nonautologous Graft Materials Used in Human Tympanoplasty

OBJECTIVES

Nonautologous graft materials may solve several dilemmas in tympanoplasty by obviating the need for graft harvest, facilitating consistent wound healing, and permitting graft placement in the clinical setting. Prior studies of nonautologous grafts in humans have shown variable outcomes. In this systematic review, we aim to 1) summarize clinical outcomes and 2) discuss limitations in the literature regarding nonautologous grafts for tympanoplasty in humans.

METHODS

A literature review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The study size, etiology and duration of perforation, type of nonautologous graft, and postoperative closure rate were assessed.

RESULTS

The PRISMA approach yielded 61 articles, including 3,247 ears that met inclusion criteria. Studies evaluated nonautologous grafts including paper patch, gelatin sponge, growth factors, porcine small-intestinal submucosa, among others. Traumatic perforations (62.3%) were most commonly studied, whereas postinfectious perforations (31.9%) and other etiologies (5.8%) comprised a minority of cases. Acute perforations of <8 weeks duration constituted just over half of all treated ears. Overall closure rate was 82.1%, with significantly higher closure rates in acute (89.9%) versus chronic perforations (64.9%, P < .01), regardless of material. A median postoperative air-bone gap of 5.6 dB was found in the 23% of studies reporting this metric.

CONCLUSIONS

The majority of publications reviewing nonautologous materials in tympanoplasty evaluate acute or traumatic perforations, and few rigorously report hearing outcomes. Given available data, porcine submucosa and basic fibroblast growth factor may hold promise for chronic perforation closure. Future studies should report closure rates and hearing outcomes in perforations >8 weeks duration. Laryngoscope, 131:392-400, 2021.
