Correlation Between Air-Bone Gap and Vestibular Aqueduct Size in Enlarged Vestibular Aqueduct Syndrome: A Systematic Review.

The purpose of this review was to evaluate the air-bone gap with vestibular aqueduct size in enlarged vestibular aqueduct syndrome. According to the PRISMA guidelines we conducted a systematic review of the literature. Published international articles in English from 2000 to 2022 were screened, checking for studies that evaluated the air-bone gap of patients affected by enlarged vestibular aqueduct syndrome and the size of vestibular aqueduct. Data related to the hearing assessment and imaging investigation of enrolled participants were extracted. The chosen primary outcome measure was the correlation between air-bone-gap and vestibular aqueduct size. The database search allowed us to screen 485 articles and to select 5 articles discussing this topic for a total of 349 patients. Two studies showed a positive correlation between air-bone gap and vestibular aqueduct size, one only a trend and two no correlation. To date, it is not possible to draw conclusions whether or not there is a positive correlation between air-bone gap and vestibular aqueduct size in enlarged vestibular aqueduct syndrome. Higher quality studies would be conducted with standardized outcome measures to clarify the specific research question.
