Background: 3D Virtual Reality (VR) offers new opportunities in vestibular science. It also presents new challenges and problems.

Aims/objectives: The study aimed to evaluate the effective factors in the 3D VR Subjective Visual Vertical (SVV) test and the impact of cybersickness on the test results.

Risk analysis in persistent cervical lymphadenopathies: Malignant or benign?

Objective: The objective of the study was to determine the parameters that can be used to predict malignancy in persistent cervical lymphadenopathies.

Methods: We retrospectively reviewed the files of 162 patients diagnosed with persistent cervical lymphadenopathy who underwent an excisional biopsy in our department between January 2011 and October 2019. Patient demographics and the size, side, duration, and localization of lymphadenopathy were recorded, and their relationship with histopathological results was investigated.
