ABSTRACT
BACKGROUND: The incidence of tinnitus has been increasing together with its patient impact and societal costs. Much research has been conducted in the field of tinnitus, especially on treatment modalities because there still is no cure. This study aims to analyze the evolutions and developments in the scientific output relating to tinnitus. METHODS: We analyzed the Science Citation Index Expanded featured articles in the Web of Science Core Collection relating to tinnitus from 1980 to 2020. The publications were analyzed by characteristics such as the countries and institutions, journals, the most cited articles and references, and the most frequently used words in the abstracts and keywords. RESULTS: In total, 8282 articles relating to tinnitus were identified in the Web of Science. The number of publications has been significantly increasing after the 1990s. Of the 8282 articles, a major part originated from the American and European institutions. Most articles originated from high-impact journals, which consequently also covered the most cited papers. A major interest was seen in areas about treatment and pathogenic mechanisms. CONCLUSION: This bibliometric analysis here indicated an increasing trend in tinnitus research from 1980 to 2020, particularly with the increase in tinnitus burden and the societal costs by it. Specific interest has been seen in the specific tinnitus pathophysiological mechanisms and treatment. Individual researchers and institutions will gain a new perspective on their future studies based on the bibliometric data in our paper.

OBJECTIVE: To compare the functional outcomes and complications of intratympanic gentamicin (ITG) versus intratympanic corticosteroids (ITC) in Menière's disease. DATA SOURCES: An electronic search was conducted in the Cochrane Library, PubMed, and Embase databases on February 3, 2019. Articles written in English, Dutch, German, French, or Turkish language were included. STUDY SELECTION: Study inclusion criteria were: 1) patients diagnosed with definite Menière's disease according to the criteria of the American Academy of Otolaryngology-Head and Neck Surgery, 2) treated with ITG or ITC in a comparison study, and 3) reported subjective and objective outcomes concerning Menière's disease. DATA EXTRACTION: The quality of eligible studies was assessed according to an adjusted version of the Cochrane Risk of Bias tool. The extracted data were study characteristics (study design, publication year, and number of relevant patients), patient's characteristics (sex and age), disease characteristics (uni or bilateral and duration of Menière's disease), treatment protocol, and different therapeutic outcomes (vertigo, tinnitus, aural fullness, and hearing loss). DATA SYNTHESIS: A total of eight articles were included for data extraction and analysis. For subjective outcomes, ITG was slightly favored compared to intratympanic corticosteroids. This was significant only in three studies (pâ<â0.05). For objective outcomes and complications, no significant differences were seen. CONCLUSIONS: The result of this systematic review shows some benefit of ITG over ITC for subjective outcomes and no difference regarding objective outcomes or complication rate. However, this superiority of ITG is rather weak. Both interventions can be effectively and safely used in controlling Menière's disease in acute situations.

OBJECTIVE: To evaluate the effectiveness of hyperbaric oxygen in the treatment of patients with idiopathic sudden sensorineural hearing loss (ISSHL). DATA SOURCES: An Embase, MEDLINE and Cochrane search were utilised to identify various clinical trials on the treatment of ISSHL. Studies that were published between 2002 and 2018 and written in the English, Dutch or German language were included. Search terms included synonyms for idiopathic sudden hearing loss. DATA SYNTHESIS: A total of 16 articles were identified regarding hyperbaric oxygen therapy. All patients were evaluated with pure-tone audiometry. A major part of the cases presented with unilateral hearing loss(bilateral hearing loss less than 5%). In several studies, the average of the mean hearing gain at five contiguous frequencies was significantly higher in the hyperbaric oxygen (HBO) therapy and systemic steroid (SS) group in patients with severe or profound hearing impairment. They recorded a significant treatment effect (p = 0.005) of HBO + SS therapy on patients with an initial hearing loss of ≥ 81 dB. CONCLUSIONS: On the whole group of ISSHL patients, no significant difference was demonstrated between the intervention and control group. However, in severe or profound hearing-impaired ISSHL patients, significant benefit was observed in the intervention group. These results likely indicate that adding HBO to steroid therapies might be of benefit in cases of severe and profound hearing impairment.
