RESUMO
Background The objective of this retrospective study was to investigate the seasonal patterns of idiopathic facial nerve paralysis, specifically Bell's palsy, in Riyadh, Saudi Arabia. The study aimed to determine if there is a correlation between cold weather and the incidence of Bell's palsy, as well as to examine the relationship between age, gender, comorbidities, and the development of the disease. Methodology Data were collected from King Abdulaziz Medical City in Riyadh, Saudi Arabia, between 2016 and 2021. Electronic medical records of adult patients diagnosed with idiopathic facial paralysis were reviewed. Patients with facial paralysis caused by known illnesses were excluded. Demographic information, clinical characteristics, and the course of the disease were analyzed using SPSS version 25 (IBM Corp., Armonk, NY, USA). Results The study included 136 Bell's palsy patients, with a mean age of 39.9 years. Males represented 58.1% (79) of the sample, and the right side of the face was more commonly affected in 71 (52.2%) patients. The majority of patients had House-Brackmann grade III (51, 37.5%). The monthly distribution showed a higher number of Bell's palsy cases during the winter months, particularly December, October, and November, but the seasonal distribution did not yield a statistically significant difference in incidence. Conclusions While this study observed a higher incidence of Bell's palsy during the winter months, it did not establish a statistically significant correlation between cold temperatures and the onset of Bell's palsy in Riyadh, Saudi Arabia. Furthermore, the study found that Bell's palsy predominantly affects middle-aged males, and comorbidities did not appear to be significant risk factors for the development of the disease. This research lays the groundwork for future investigations into the relationship between weather and the pathogenesis of Bell's palsy in the region.
RESUMO
BACKGROUND: Following rhinoplasty, external nasal splints are used to reshape the cartilage and reposition the nasal bone. Despite the popularity of using an external nasal splint in rhinoplasty procedures, there is still a lack of evidence of the effectiveness of using the external nasal splint post-rhinoplasty. This systematic literature review aimed to evaluate the evidence regarding the use of external nasal splints following rhinoplasty. METHODS: A systematic search of Cochrane, Medline, and Embase databases was conducted in September 2022. The literature was screened independently by two reviewers, and the data were extracted. Our search terms included septorhinoplasty, rhinoplasty, osteotomy, splinting, nasal splinting, and external nasal splinting. RESULTS: Initially, 1617 articles were identified, but only four articles were included in the final review. The included studies were all published between 2016 and 2021. The included studies recruited 2425 patients, 20 of whom used external splints and 2415 did not. Out of 2415 patients who did not use an external nasal splint, there were 151 patients with moderate periorbital edema and ecchymosis. There was a decrease in nasal width in 99% of the patients who did not use external nasal splinting postoperatively. CONCLUSION: According to our findings, nasal splinting should not be routinely used following rhinoplasty, but only in certain patients. There is no clear evidence that nasal splints reduce complications, and complications occurred among both patients with and without external nasal splints. Further studies need to be conducted to confirm this conclusion. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.
