RESUMO
PURPOSE: Chronic rhinosinusitis (CRS) is a prevalent chronic disease observed on a global scale. The utilization of endoscopic sinus surgery (ESS) has gained significant recognition as an effective intervention for individuals with CRS and nasal polyps who have not responded to conventional treatments. The need (or not) for revision surgery frequently relies on the promotion of optimal wound healing. The impact of platelet-rich plasma (PRP) on tissue healing has been extensively examined in various surgical fields. METHODS: The present prospective study involved 30 patients suffering with nasal polyposis who underwent endoscopic sinus surgery. 15 patients were assigned to the PRP group, and 15 patients to the control group. The clinical follow-up of the patients took place at specific intervals, at weeks 1, 2, 3, 4, 8, and 12 after the surgical procedure. The evaluator identified the existence of adhesions, crusting, bleeding, granulation and infection using a visual analogue scale score. The patients also completed the SNOT 22 questionnaire prior to surgery and at each postoperative visit. RESULTS: The present study observed a lower incidence of adhesion, infection, hemorrhage and granulation in the PRP group. Furthermore, a statistically significant difference was detected between the groups. CONCLUSION: Based on the findings of the present investigation, it seems that platelet-rich plasma (PRP) is beneficial on wound healing during the early stages following the surgical procedure. The technique is characterized by its limited invasiveness, which contributes to its low risk profile and the achievement of clinically good outcomes.

Background: Platelet-rich fibrin is a second-generation platelet concentrate. It is rich in platelets, cytokines, growth factors and leukocytes. Compared to platelet-rich plasma, it releases growth factors for a more extended amount of time. Methods:A literature review was conducted on the applications of platelet-rich fibrin in otolaryngology. Only articles written in English were further considered for the study; all others were excluded. Also, articles relating to oral and maxillofacial surgery were removed. Results: Twenty-five studies were deemed appropriate for inclusion in the present review. Conclusion:Based on the current data, platelet-rich fibrin appears to be a safe, healing-promoting material. It is a cost-effective, autologous material with enormous therapeutic application potential in the future. However, further clinical research is required before conclusive conclusions can be drawn about its usefulness.
RESUMO
Background:Dizziness is a commonly referred symptom in emergency departments (EDs). The aim of this study is to describe the epidemiology of dizziness included acute vestibular syndrome (AVS) in the ED of the University Hospital of Ioannina, Grecce, during a six-month period. Methods:A total of 60 patients presenting with dizziness to the ED of our hospital during a short period of six months in 2021 were identified. Data were obtained through retrospective and prospective review of medical records. Statistical analysis was based on ÉBM-SPSS Statistics 26.0. Results:Among the 60 patients, 16.67% received the diagnosis of cerebellar stroke, 3.33% Meniere disease, 16.67% vestibular neuritis, 20% benign paroxysmal positional vertigo, 3.33% cardiovascular disease, and 1.67% had a neurological disease. Finally, 35% of patients left the ED undiagnosed. Conclusion:Benign paroxysmal positional vertigo was found to be the most common cause of dizziness in the ED, followed by cerebellar stroke and vestibular neuritis. A detailed neurological examination is recommended for the diagnosis of dizziness in the ED. Our data confirm the findings of previous studies in the GreeK population of patients presenting with dizziness to the ED of our hospital.
