Objective:
We aimed to perform a systematic review and meta-analysis of myringoplasty outcomes following platelet concentrates application in patients with chronic otitis media (COM).
Data Sources:
We searched MEDLINE, Embase, and Cochrane Central register of Controlled Clinical Trials (CENTRAL). We also performed a manual search in Google Scholar and reference lists.
Review Methods:
Eligible for inclusion were randomized controlled trials on COM patients undergoing myringoplasty with platelet concentrates (platelet-rich plasma or platelet-rich fibrin) compared to myringoplasty alone. The primary outcomes were graft uptake and air-bone gap (ABG) gain, while the secondary outcome was complication rate. We used odds ratio (OR) and standardized mean difference (SMD) to represent dichotomous and continuous outcomes, respectively.
Results:
Thirteen trials (n = 1179) were deemed eligible. Platelet concentrates significantly improved graft uptake after 6 months (OR: 2.45, 95% confidence interval [CI]: 1.34-4.47, P = .004, I2 = 0%, high certainty), ABG gain (SMD: 0.36, 95% CI: 0.17-0.55, P = .0002, I2 = 0%, moderate certainty), and complication rate (OR: 0.38, 95% CI: 0.18-0.82, P = .01, I2 = 0%, low certainty).
Conclusion:
Our results showed that platelet concentrates may improve graft uptake and ABG gain and reduce complications in COM patients undergoing myringoplasty. Caution is warranted given to the relatively small sample size, as well as inconsistent reporting across included trials.

Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
