Background

Acoustic neuroma is the most common extra-axial primary cerebellopontine angle tumor in adults. A plethora of studies have been published on acoustic neuroma, but none of the previous works have highlighted the most influential articles. Our objective was to perform a bibliometric analysis of the 50 most-cited articles on acoustic neuroma.

Methods

We performed a title-specific search on the Scopus database using the following search terms: “acoustic neuroma,” “vestibular schwannoma,” and “cerebellopontine angle.” We recorded the 50 most-cited articles and reviewed them.

Results

The 50 most-cited articles had an average of 175 citations per article. All articles were published between 1980 and 2006, with 1997 the most prolific year, when 7 articles were published. The journals Neurosurgery and Laryngoscope published 10 and 8 of these articles, respectively. The most common study categories were nonsurgical management (17/50) and surgical management (13/50). Studies were predominantly published by otolaryngologists (22/50) and neurosurgeons (14/50). Douglas Kondziolka was the author with the highest number of contributions, with 7 publications. The majority of the articles were produced in the United States (64%).

Conclusions

Identifying articles on acoustic neuroma with the most impact provides an important overview of the historical development of treatment methods and publication trends related to this condition. A finalized, comprehensive list of the most important works represents an excellent tool that can serve as a guide for evidence-based clinical practice.

Introduction

Acoustic neuroma is a benign, slow-growing neoplasm arising from the nerve sheath of the vestibular branch of the vestibulocochlear nerve. It is the most common tumor of the cerebellopontine angle and the internal auditory canal,1, 2 with an incidence of 0.6–0.8 per 100,000 persons per year.3, 4, 5 The first case of acoustic neuroma was reported in 1777 by Sandifort.5 In 1894, Ballance performed the first successful resection of acoustic neuroma.6 In 1925, the surgical mortality rate was 67%–84% according to Walter Dandy, whereas Harvey Cushing reported that the mortality rate was only 11%.7 In 1951, radiosurgery was introduced as a treatment option by Lars Leksell8 and, over the following 20 years, the outcome of radiosurgery improved significantly.

Today, the available management options for acoustic neuroma are microsurgical resection, stereotactic radiosurgery, and observation of patients using imaging surveillance.9, 10 The continuous expansion of the scientific literature to achieve a multidisciplinary overview compelled us to highlight the most important work to help guide future practice.11 Although bibliometric analyses have been conducted in many fields, such as neurosurgery,12, 13, 14, 15 orthopedic surgery,16 otolaryngology–head and neck surgery,17 radiology,18 and anesthesiology,19 no such analyses have been performed solely on acoustic neuroma. We aimed to conduct a bibliometric analysis of the 50 most-cited works on acoustic neuroma and to provide this as a guide for health care providers in that field.

Search Strategy

In April 2017, we conducted a title-specific search of the Scopus database to identify highly cited works on acoustic neuromas. In our search, we used the following keywords: “acoustic neuroma,” “vestibular schwannoma,” and “cerebellopontine angle.” The search results were arranged in descending order, with the article with the highest citation count (CC) positioned at the top. We then collected and analyzed the 50 most-cited articles.

Data

The following significant data were collected: article

Article Analysis

Our search query returned 5171 articles. Of these, the 50 most-cited articles were identified with the following data recorded: CC, CY (rank), first author, title, year of publication, and publishing journal (Table S1). Overall, the 50 most-cited articles had an average of 175 citations per article. All articles were published between 1980 and 2006, with 19 articles published between 1995 and 1999, which represents the peak period of acoustic neuroma publication (Figure 1). The most prolific

Discussion

Bibliometric studies do not necessarily prove the quality of the articles examined; however, the research value and importance an article has in the medical literature can be roughly determined by the number of citations it has received. In addition, analysis of the myriad number of published articles in the field of acoustic neuroma highlights the accumulation of knowledge that has occurred over time. Therefore, we undertook analysis of the top 50 most-cited articles on acoustic neuroma.

Conclusions

Using the Scopus database, we identified the 50 most-cited articles on acoustic neuromas. Most of the 50 articles were written by neurosurgeons and otolaryngologists, and the majority were published in the journals Neurosurgery and Laryngoscope. Furthermore, most of the articles focused on the use of nonsurgical interventions, such as stereotactic radiosurgery and microsurgical resection, for the treatment of acoustic neuromas. This bibliometric analysis can serve as a guide for future research
