Abstract
Ultrasound and nanomaterials are becoming flexible and revolutionary approaches to diagnosing cancer, especially head and neck cancers. This review explores the synergistic combination of nanomaterials that improve diagnostic accuracy with ultrasonography. Despite the head and neck's complex anatomy, functionalized nanoparticles as contrast agents improve ultrasound resolution and tissue differentiation. Multifunctional nanomaterials go beyond imaging to give targeted drug administration, treatment monitoring, and real-time tumor visualization. They can additionally serve both diagnostic and therapeutic functions. Due to its versatility, the ultrasound-nanomaterial platform is particularly attractive for comprehensive cancer management. Future research must focus on optimizing the design of nanoparticles by enhancing their surface modification for improved biocompatibility and controlled drug-loading capacity, which are crucial for effective targeted delivery in oncology. The development of biodegradable nanoparticles with optimized pharmacokinetics will play a pivotal role in reducing systemic toxicity. This review systematically examines the integration of nanomaterials with ultrasound imaging techniques, particularly ultrasound-guided theranostics, which have the potential to enable real-time monitoring of tumor response to therapy. These advancements in nanoparticle design and ultrasound-based diagnostics can significantly improve the accuracy of early detection, precise drug delivery, and the customization of treatment strategies for head and neck cancers, ultimately enhancing patient outcomes.
