Background: Sinonasal malignancies are a rare, heterogeneous group of tumors that o en present at an advanced stage and require multimodal therapy. The presence of high-grade toxicity and sinonasal complications a er treatment can negatively impact quality of life. In this study we aim to describe pos reatment morbidity in patients with sinonasal malignancy.
Methods:A retrospective analysis of all patients treated for sinonasal malignancy was conducted from 2005 to 2018 at a tertiary referral institution. A total of 129 patients met the inclusion criteria. Primary outcomes were treatment details, pathology, pos reatment complications, and radiation toxicity. Fisher's exact test, chi-square test, and Student t test were used for statistical analysis.Results: Mean age was 58.4 (median, 61; range, 19-94) years. A er diagnosis, 24 patients had surgery alone, 46 had surgery with radiation alone, 47 had surgery with chemoradiation, and 14 received definitive chemoradiation. Overall, 10.4% (n = 12) of patients had postoperative complications, and 21.0% (n = 22) had high-grade (grade 3-5) radiation toxicity. A er radiation, 20% (n = 21) of patients had chronic sinusitis requiring functional endoscopic sinus surgery and 20% (n = 21) had symptomatic nasal obstruction requiring operative debridement.
Conclusion:Sinonasal complications, including nasal obstruction and chronic sinusitis, occur frequently a er definitive treatment of sinonasal malignancy and should be addressed when considering quality of life in survivors. These complications occur more frequently in patients who undergo chemoradiation as opposed to surgery alone. C 2020 ARS-AAOA, LLC.
