Abstract

Objectives: To describe the clinical and paraclinical characteristics of rhinosinusitis in patients with arch cancer after radiation therapy. Methods: descriptive study of the cluster of cases. Results: Among 50 nasopharyngeal carcinoma patients after radiotherapy at the Central Otolaryngology Hospital participating in the study, there were 64% male, 36% female, the average age of the study subjects was 46.7 ± 13.6 years old. After radiation therapy, 48% of patients had advanced rhinosinusitis. Among patients with rhinosinusitis before radiation therapy, 57.7% worsened after radiation therapy. Functional symptoms include nasal discharg (80.0%), nasal blockage (78.0%), smell disorder (22.0%), craniofacial pain (14.0%). Physical symptoms include: facial swelling (6.0%), canine pain score (10.0%), Grunwald pain score (2.0%), Ewing pain score (2.0%). Among 29 nasal sinus fluid samples (pus) cultured to identify bacteria, only 2 samples were negative, accounting for 6.9%. Among 27 positive samples, Staphylococcus aureus bacteria were found the most, accounting for 44.8%.  Conclusion: The rate of rhinosinusitis in nasopharyngeal cancer patients after radiation therapy is high, so there should be measures to prevent rhinosinusitis in this group of patients.
