Maxillary mass/swelling was the most common chief complaint.  The mean gap between initial symptoms and consult was 6.77 months.  Initial biopsies were obtained from the maxillary sinus in 16 patients, with 1 patient noted to have undergone malignant transformation from a prior intranasal squamous papilloma.  Staging was advanced (Stage IVA in 16, IVB in 4, and III in 2), with no patients with Stage I or II disease.  Sixteen (16) patients underwent surgery and radiotherapy, while 6 patients received radiotherapy (RT) with or without chemotherapy.  Regional and distant metastases were uncommon.</p> <p><strong>Conclusion:</strong> In this series, maxillary sinus SCC occurs more in males, with a maxillary mass as the most common chief complaint.  Delay in treatment is common, with a mean gap of 6 months between initial symptoms and consult.  Neck node metastasis is uncommon, and most patients undergo surgery with radiotherapy as treatment.</p> <p> </p> <p><strong>Keywords:</strong> <em>maxillary sinus cancer; paranasal sinus cancer; squamous cell carcinoma</em></p> <p> </p>}, number={1}, journal={Philippine Journal of Otolaryngology Head and Neck Surgery}, author={Hernandez, Anna Kristina M. and Cabungcal, Arsenio Claro A.}, year={2019}, month={Jun.}, pages={34–37} }
