Update on Rhinoplasty Research Trends: A Bibliometric Analysis

Comparative Study of the Effects of Clonidine and Tranexamic Acid on Intraoperative Bleeding in Rhinoplasty: A Clinical Trial

Introduction

The present study was conducted to compare the effects of clonidine and tranexamic acid on the volume of bleeding and quality of the surgical field in terms of bleeding in candidates who underwent rhinoplasty.

Methods

In this two-sided clinical trial, candidates eligible for rhinoplasty were randomly assigned to two treatment groups: tranexamic acid and clonidine. The first group received tranexamic acid at a dose of 700 µg/kg of body weight 2 hours before the surgical procedure, whereas the second group received clonidine orally at a dose of 2 mg/kg of body weight, 90 minutes before surgery. Subsequently, the volume of bleeding was calculated based on the amount of blood collected via suction and in blood-soaked gauze, which was previously weighed.

Results

Among the 92 patients who underwent rhinoplasty, 82% were women. The mean age and standard deviation (SD) of individuals who underwent rhinoplasty were 29.22 ± 8.50 years. There were no significant differences between the two treatment groups in terms of age, gender, and body mass index. The volume of blood collected via suction during rhinoplasty, categorized into surgery duration <63 minutes and ≤63 minutes, showed a significant difference between the 2 treatment groups.

Conclusion

The use of tranexamic acid, compared with clonidine, resulted in lesser intraoperative bleeding and better surgical field quality. Considering the superior effectiveness of tranexamic acid in reducing intraoperative bleeding, it is recommended to use tranexamic acid instead of clonidine in rhinoplasty.

Trends in Rhinoplasty Research in Saudi Arabia: A 30-Year Bibliometric Analysis

Rhinoplasty is one of the most commonly performed aesthetic surgeries. Saudi Arabia has a large number of rhinoplasty publications. Here, we aimed to assess the past, present, and future research output related to rhinoplasty in Saudi Arabia and compare it with global output. We performed a bibliometric analysis to evaluate rhinoplasty research productivity trends in Saudi Arabia from 1995 to 2021 in both cosmetic and reconstructive rhinoplasties. We considered all publications whose first authors were from Saudi Arabia or whose authors contributed significantly to a paper from Saudi Arabia, even though the first author was not from the Kingdom of Saudi Arabia. We evaluated the research quality of the articles using the impact factor of the journal in which the article was published. For each article, the number of authors, number of citations received, study design, region of the first author, and the level of evidence were collected. We gained several insights into the global trends of rhinoplasty in research and its position. We observed a significant increase in the number of publications on rhinoplasty in Saudi Arabia. Although there was no significant increase in the impact factor, most publications had a level of evidence of I or II.

Facial Rejuvenation: A Global Trend of Dermatological Procedures in the Last Decade

Background

We aimed to track the global trend of cosmetic treatment outcomes for facial rejuvenation and the differences in modalities used in East Asian and Western populations.

Methods

Articles reporting on facial rejuvenation procedures (invasive/noninvasive) were identified in PubMed from 2013 to March 2023 and bibliometrically analyzed for type of published document, citation frequency, authors with most articles, author's affiliation, and frequency distribution of keywords.

Results

From 553 articles, most were published in 2021 (n = 86, 15.6%). Western countries (n = 323, 58.4%) contributed more than East Asian (n = 230, 41.6%), with more invasive interventions (n = 355, 64.2%) than noninvasive techniques (n = 198, 35.8%). Numbers of invasive techniques in West versus East Asian countries were 225 (40.7%) versus 135 (24.4%). Main indications were the reduction of facial wrinkles and antiageing treatments. Hyaluronic acid, fillers, and botulinum toxin were the main hotspots for invasive treatments, whereas laser, platelet-rich plasma, and radiofrequency were for noninvasive treatments. Nasolabial folds (13.4%) and glabellar lines (12.4%) were the top research hotspots in the East Asian and Western regions. Common adverse events were pain, erythema, swelling, and bruising. Approximately, 89.3% of publications were from single countries, whereas 10.7% of publications were from international collaborations. Most articles (n = 387; 69.95%) presented their findings using level II evidence. Dermatological surgery (IF = 2.914) had the greatest number of publications (n = 109; 19.71%).

Conclusions

The main hotspots were antiaging and youthfulness. This study provides a trend and a new perspective on the future research directions in the field of facial rejuvenation.

The Research Trend of Soft Tissue Filler Injection from 2000 to 2022: A Bibliometric and Visualized Analysis

Background

The demand for soft tissue filler injections has experienced a significant increase in recent years. Therefore, this study used bibliometric analysis to identify prominent research areas and emerging trends within the field.

Methods

Publications concerning research on soft tissue filler injections were collected from the Web of Science Core Collection database. Subsequently, VOSviewer 1.6.18 and CiteSpace 6.2.R4 software were used to analyze the co-authorship, co-occurrence, and citations of countries, institutions, authors, hotspot keywords, and journals associated with these studies.

Results

A total of 1370 records pertaining to filler injection research conducted between 2000 and 2022 were identified. The United States (524 publications) emerged as the country with the highest number of publications in this field, with Mayo Clinic (37 publications) making the most substantial contribution. Dermatologic Surgery emerged as the leading journal in this field, publishing the highest number of research articles (151 publications) and also being the most frequently co-cited. Cotofana proved to be the most prolific author with 51 publications, and Lemperle emerged as the most frequently co-cited author with 628 citations (including total link strength: 6587). The most popular keywords, in descending order of popularity, were "dermal filler," "injection," "soft-tissue augmentation," "complications," and "hyaluronic acid."

Conclusions

The findings of this study offer a comprehensive overview of the main directions in filler injection research. Furthermore, they underscore the imperative of intensifying efforts to prevent complications linked to filler injections.
