Abstract
Background
Paranasal sinus malignancies are rare and frequently present at an advanced stage. The optimal management of the clinically or radiologically N0 neck remains controversial.Aims/objective
To evaluate cervical lymph node management based on preoperative radiological findings and long-term oncological outcomes in patients with advanced paranasal sinus malignancies.Material and methods
Thirty-four patients who underwent surgery for T3 or T4a paranasal sinus malignancies between 2014 and 2020 were retrospectively evaluated. Overall survival (OS) and disease-free survival (DFS) were estimated using Kaplan-Meier analysis, and survival curves were compared using the log-rank test.Results
Twenty-seven patients (79.4%) had T3 and seven (20.6%) had T4a disease. Eight patients (23.5%) had radiologically suspicious cervical lymph nodes and underwent neck dissection; two (25.0%) had pathological nodal metastasis. Cervical recurrence occurred in three patients (8.8%), and 14 (41.2%) experienced local or cervical recurrence. Five-year OS and DFS were 48.6% and 49.4%, respectively. T4a disease was associated with poorer DFS (p Conclusions and significance
Cervical nodal involvement was uncommon. Our findings do not provide evidence supporting routine elective neck treatment in radiologically N0 patients. T4a disease was associated with poorer DFS.
