An evaluation of factors which affect recurrence and malignancy of sinonasal papillomas.

OBJECTIVE

Sinonasal papillomas are rare benign tumors. They challenge otorhinolaryngologists due to their high recurrence rate and malignant transformation. The aim of this study was to investigate the clinical and demographic factors associated with recurrence and/or malignancy of sinonasal papillomas.

METHODS

This retrospective study included 49 patients who were operated on between 2014 and 2020. Clinical and demographic characteristics of the patients were retrieved from the patients' records.

RESULTS

The recurrence rate was determined to be 12.2% and the malignancy rate was 8.2%. Recurrence was significantly higher in females, the advanced stage (T3 and T4), and papillomas located in the maxillary sinus. The recurrence rate was significantly lower in patients treated with the endoscopic surgery. Factors affecting malignancy were the presence of dysplasia and extension out of the paranasal sinuses.

CONCLUSIONS

The results of this study showed that the factors affecting recurrence were gender, papilloma stage, type of surgery performed, and whether the tumor extended to the paranasal sinuses.
