Epidemioclinical, Histopathological and Therapeutic Aspects of Nasosinus Tumours at the Brazzaville University Hospital

Objective: To describe the epidemiological, clinical, histopathological and therapeutic aspects of nasosinus tumours at Brazzaville University Hospital.

Materials and Methods: We carried out a retrospective descriptive study over a period of 05 years on cases of nasosinus tumours diagnosed in patients over 6 years of age at the Brazzaville University Hospital and for which anatomopathological results were available.

Results: During the study period, 52 patients suspected nasal and/or sinus tumours (maxillary and/or ethmoidal), representing a frequency of 5.09%. The average age was 50 ± 12.5, with a sex ratio of 2.1. Diabetes (21.1%) and hypertension (17.3%) were the main antecedents. The most common socio-professional category was blue-collar (44.2%), and the most common functional sign was epistaxis (32.7%). According to histological type, benign nasosinus tumours were more frequent, with 37 cases (71.1%); malignant nasosinus tumours with regional extension were first biopsied and then possibly treated with additional radiotherapy; however, all benign nasosinus tumours were operated on.

Conclusion: NSTs are relatively rare and can be diagnosed at any age. They are dominated by benign tumours, notably inverted papilloma. Surgery remains the treatment of choice in our context.
