- Abstract
Although rare, sinonasal malignancies (SNM) can be lesions of immense importance. Approximately 60-70% of sinonasal malignancies (SNM) occur in the maxillary sinus and 20-30% occurs in the nasal cavity itself. The lymphatic drainage of the sinuses and nasal cavity include levels I-III as well as the parapharyngian nodes. Elective regional lymph node dissections became controversial because of overtreatment of the many patients without lymph node metastases. Lymphatic metastasis is the most important mechanism of spread in sinonasal squamous cell carcinoma considering the vast network of vessels in this area. The indications and type of neck dissection to be performed in the positive node neck and management of the N0 neck remain controversial. The sentinel lymph node concept is based on the Halsted theory that stressed the importance of locoregional cancer treatment because of the far site spread. Each patient with head and neck malignancies, including sinonasal carcinoma have about 2-3 sentinel lymph nodes of which up to 40% of them contain metastases.
