Advances in Skin Ultrasonography for Malignant and Benign Tumors of the Head and Neck: Current Insights and Future Directions

Abstract

Ultrasound imaging has become an indispensable diagnostic tool across various medical fields. In recent years, there has been growing interest in the use of ultrasonography for the evaluation of skin lesions. However, scientific reports detailing the precise role of ultrasound in determining the morphology of malignant skin tumors still remain limited. Malignant skin lesions, particularly in the head and neck region-their most common location-pose significant challenges due to the complex anatomy of these areas. The primary treatment for non-melanoma skin cancers, including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), is surgical excision. Mohs micrographic surgery is considered the gold standard due to its tissue-sparing approach and high cure rates. However, it is a time-consuming and resource-intensive procedure that is not always widely accessible. In contrast, standard surgical excision, while more widely available, often results in incomplete tumor removal, necessitating subsequent surgical radicalization or the use of adjuvant therapies. Routine ultrasound evaluation of both benign and malignant skin lesions could enhance early detection and facilitate timely treatment. However, the current body of evidence for the usage of skin ultrasound in presurgical evaluation is poor and lacks standardization. Given these challenges, in this review, we aim to highlight the potential value of preoperative skin ultrasonography in accurately assessing benign and malignant skin lesion dimensions and morphology.

Keywords: Mohs surgery; basal cell carcinoma; high-frequency ultrasonography; melanoma; squamous cell carcinoma.
