Introduction: Chronic rhinosinusitis (CRS) can be associated with tumors involving the maxillary sinus, but outcomes after undergoing maxillectomy with free flap reconstruction remain unclear.
Methods: A retrospective analysis of medical records was performed to evaluate evidence of CRS in patients who underwent maxillectomy with free flap reconstruction at a single tertiary care academic institution from 2013 through 2020.
Results: Eighty-four patients were assessed. Nineteen (22.6%) patients were diagnosed with CRS after surgery, 23 (27.4%) patients were treated for sinus symptoms, and 49 (58.3%) had radiographic evidence of sinus inflammation for more than 6 months. Risk factors for requiring sinus treatment included adjuvant or neoadjuvant chemotherapy (p = 0.002) and pre-operative use of sinus medication (p < 0.001). Radiographic evidence of sinusitis 6 months after surgery is also closely associated with sinusitis treatment (p = 0.051).
Conclusions: CRS may be underdiagnosed in patients undergoing maxillectomy with microvascular reconstruction. Further evaluation into patient sinus disease and symptoms following neoplastic surgery may lead to a higher quality of life in some long-term survivors.
