Exploring trends and developments in cholesteatoma research: a bibliometric analysis.

ABSTRACT

PURPOSE: Examination of the scientific literature on cholesteatoma from past to present using bibliometric methods. METHODS: A total of 2353 articles on cholesteatoma between 1980 and 2023 were obtained from the Web of Science database and statistically analysed using bibliometric techniques. RESULTS: The journals with the highest number of contributions to the literature were Otology & Neurotology (n = 192), Acta Oto-Laryngologica (156) and Laryngoscope (149). The most impactful journals based on h-index and total citation (TC) counts were Laryngoscope (h36, TC 4241), Otology & Neurotology (29, 3141), and American Journal of Otology (26, 2071) respectively. The most prolific author was Kojima H. (n = 49). According to the findings of the Reference Publication Year Spectroscopy (RPYS) analysis, there has been a significant increase in academic interest in Cholesteatoma since its first description in 1959, particularly following the expansion of its definition in 1977. Subsequently, the trend of increased interest has risen rapidly in later years, with notable peaks in research intensity observed in 1989, 2006, and 2011. The highest academic trend occurred in 2006. In recent years, trending topics have included innovative approaches such as diagnostic and imaging methods particularly alongside technological developments, endoscopic surgery, recurrence and complications, prognosis and quality of life, artificial intelligence, and obliteration. CONCLUSION: In conclusion, the evolution of cholesteatoma and its research priorities reveal temporal shifts and emerging areas of interest over time. Primarily, diagnosis, treatment, and surgical approaches remain central. Additionally, research has expanded to encompass developments in surgical techniques, imaging modalities, cellular biology, pathology, and molecular mechanisms.
