Prospective Observational Study of Sinonasal and Skull-base Tumours Management in a Tertiary Referral Otorhinolaryngology Service

Sinonasal tumours and tumours that involve the adjacent skull base are rare entities. However, their management necessitates a special knowledge of ENT areas and specifics of sinonasal anatomy and skull base. Due to the heterogeneity of pathological diagnoses of sinonasal and skull-base tumours, one of the main aims of this study is to provide epidemiological characteristics in our geographical area. Furthermore, to compare with other tertiary referral centres, we will analyse management results, which could improve the management of these diseases. Since the sinonasal area and skull base house several important neuroanatomical structures and senses, we aim to provide an analysis of the patient-reported quality of life.
