Objective: To analyze the necessity and effectiveness of vestibular rehabilitation training instruction in the treatment of sudden deafness accompanied by vertigo. Methods: Sixty medical staff who learned the treatment methods for sudden deafness accompanied by vertigo (vestibular rehabilitation training) from January 2024 to February 2025 were selected as the research subjects. They were divided into two groups according to the time of study: the control group, who participated in the training teaching first, and the observation group, who participated later. Each group had 30 people. The control group received conventional training, while the observation group underwent continuous quality improvement. The effects and assessment results of different teaching methods were compared. Results: The theoretical and practical assessment scores of medical staff in the observation group were higher than those in the control group (p < 0.05); the satisfaction of medical staff in the observation group with the teaching mode was higher than that in the control group (p < 0.05). Conclusion: Vestibular rehabilitation training has significant effects on sudden deafness accompanied by vertigo. Training medical staff not only enhances their understanding of training methods but also enables them to provide specialized guidance to patients, improving their vertigo condition.
