Trends in Rhinoplasty Research: A 20-Year Bibliometric Analysis

Overview

This study catalogued 20 years of rhinoplasty publishing to see where the research comes from, what it covers, and how strong it is. The authors built a database from the top 15 plastic surgery and otolaryngology journals, classified by impact factor, geography, study design, evidence level, and topic.

Sections of note

• 1,244 rhinoplasty articles from 1994 to 2013 across the top 15 journals by impact factor.
• Mean impact factor among those journals rose from 0.75 in 1994 to 1.90 in 2013, p below 0.001.
• 91.0 percent of publications were clinical in study design.
• Evidence levels were predominantly weak: level IV 42.4 percent, level V 33.2 percent.
• Publication volume and productivity index by region: United States 37.9 and 41.2 percent, Asia 29.1 and 28.2 percent, Western Europe 18.8 and 18.2 percent.
• Topic split: 60.4 percent aesthetic, 30.6 percent reconstructive, with a significant increase in the aesthetic proportion per year, p 0.009.
• The United States has been consistently most productive but its lead has diminished over the 20 years. Level of evidence III.

What it means for a patient

• Three quarters of rhinoplasty research falls into the two weakest evidence categories, meaning case series and expert opinion.
• Research has shifted toward cosmetic topics and away from reconstructive ones.
• Publication is increasingly distributed beyond the United States, with Asia close behind.
• Limits: this counts and classifies publications; it does not assess whether their conclusions are correct, and it covers only the top 15 journals.

Why this paper matters

The literature's evidence level sets a ceiling on how well grounded standard rhinoplasty practice can be, and this quantifies that ceiling across two decades. The authors call for stronger study designs. The analysis stops in 2013, so it does not show whether evidence quality has since improved.

Terms

• Bibliometric analysis: Counting and classifying publications to measure a field.
• Impact factor: A score reflecting how often a journal's articles are cited.
• Level of evidence: A ranking of study designs; level IV is case series, level V expert opinion.
• Productivity index: A measure of a region's research output relative to expectation.
• Reconstructive rhinoplasty: Nose surgery to repair damage or a birth difference rather than for appearance.
