ABSTRACT
The presence of cervical metastasis has substantial negative impact on survival of patients with laryngeal cancer. Bilateral elective selective neck dissection of levels II, III and IV is usually the chosen approach in these patients. However, there is significant morbidity associated with level IV dissection, such as phrenic nerve injury and lymphatic fistula. The objective of the present study was to evaluate the frequency of metastatic nodes in level IV in clinically T3/T4N0 patients with laryngeal cancer. The pathological reports of 77 patients with clinically T3/T4N0 laryngeal squamous cell carcinoma were reviewed. Patients underwent bilateral lateral neck dissection from January 2007 to November 2012. The surgical specimens were subdivided in levels before evaluation. There were 12 patients with neck metastasis (15.58%). In 3 cases (3.89%), there were metastatic lymph nodes in level IV, all T4 and with ipsilateral metastasis. In conclusion, the incidence of level IV metastasis was 3.89%, an in all patients was staged as T4.
