An ENT (Ear, Nose, and Throat) expert witness focuses on diagnosing and treating diseases and disorders involving the ear, nose, and throat, often managing less invasive medical conditions. In contrast, a head and neck surgery expert witness specializes in surgical interventions involving both benign and malignant tumors, trauma repair, and complex reconstructive procedures within the head and neck region. While their fields overlap, the head and neck surgery expert tends to be more surgically focused and may address more complex anatomical and oncologic issues than an ENT specialist.
