Objective: To determine the morbidity and mortality and the risk factors associated with cervical lymphadenectomy. Method: Cross-sectional study; patients undergoing cervical lymphadenectomy were included in any of its variants, secondary to the recurrence of some neoplastic entity; from January 2011 to November 2016. Results: 311 patients were included of which 65.3% were women and 49 ± 17.2 years old. The most frequent diagnoses were thyroid cancer 194 (62.4%) and recurrent laryngeal cancer 22 (7.1%). Asymptomatic patients had 53.4% of the patients and 119 (38.3%) presented masses or nodules in the neck, with level III being the most affected with 276 (88.7%) patients. Overall morbidity was 17% and mortality was 5.8%. The factors related to mortality were: present symptomatology (p = 0.006), involvement of level I (p = 0.005), extensive lymph node dissection (p = 0.01), and vascular complications (p = 0.0001) and the wound (p = 0.01). Conclusions: Due to the lymphatic dissemination pattern of head and neck tumors, selective lymphadenectomy plays a crucial role in the treatment of these neoplasms. We have opted to perform more conservative surgeries, as long as the main oncological objectives are preserved.
