supraomohyoid neck dissection steps

The consensus decision was to call modified radical neck dissection those procedures that preserve some of the nonnodal structures that were excised during the classic procedure. If the surgery is performed with other procedures that are more complex and prolonged, a Foley catheter is inserted for better control of urine output. This type of neck dissection is indicated in the surgical management of the neck in patients with large T2, T3, and T4 squamous cell carcinomas of the oral cavity in whom the cervical lymph nodes are either clinically negative (NO) or single, discrete, and less than 3 cm in diameter (N1).
