Abstract: Parotid gland diseases are highly diverse, including neoplastic lesions, inflammatory diseases, autoimmune diseases, and etc. Owing to the complex anatomical structure of the parotid gland and its involvement with vital structures such as the facial nerve, accurate preoperative diagnosis directly influences the making of surgical plans and prediction of the prognosis of patients. High-frequency ultrasound(HFUS), as the preferred imaging examination method for parotid gland diseases, plays a crucial role in disease diagnosis, treatment decision-making, and follow-up due to its advantages of real-time imaging, non-invasiveness, and high resolution. In recent years, with the development of new technologies like elastography, contrast-enhanced ultrasound, and interventional ultrasound, the application value of HFUS in the diagnosis and treatment of parotid gland diseases has been significantly enhanced. This article reviewed the technical advantages of HFUS, elaborated on its applications in the diagnosis of parotid gland diseases, the differentiation of benign and malignant tumors, and the anatomical assessment of the parotid gland (determining the positional relationship between tumors and facial nerve), and discussed the technical strengths, weaknesses, and future development directions of this technology.

Key words: Parotid gland diseases, High-frequency ultrasound, Elastography, Contrast-enhanced ultrasound, Imaging diagnosis
