[The incidence of level I metastasis in laryngopharyngeal squamous cell carcinoma].

Objectives: We investigated the incidence of level I metastasis in patients with laryngeal and hypopharyngeal squamous cell carcinoma (SCC).

Patients And Methods: The records of 126 patients who underwent primary tumor excision with radical neck dissection (RND) or its modifications for laryngeal or hypopharyngeal SCC were retrospectively reviewed. Preoperative tumor and neck stages, the sites and the number of metastatic lymph nodes were recorded.
