Tumours of Nasal Septum: A Retrospective Study of 32 Patients

Objective: Tumours of the nasal septum are a rare and heterogeneous group of lesions in the sinonasal tract. The management of the different lesions of this site is debated. The aim of this study is to share our experience on a rare clinical condition and stimulate other centres to publish theirs. Methods: We retrospectively analysed the databases of sinonasal tumours treated at the Sections of Otolaryngology (ENT) of two University Hospitals (Palermo and Genova) between 2012 and 2020. Results: From the two databases, a cohort of 32 patients with tumours of nasal septum were selected. All patients underwent an endoscopic examination. Large tumours underwent preoperative computed tomography (CT) scan without contrast medium. In 22 (68.7%) cases, the preoperative radiologic evaluation also included magnetic resonance imaging (MRI) with gado-linium to obtain a better differentiation of the lesions and study the vascular pattern. All the large lesions were biopsied under endoscopic guidance using local anaesthesia; the same approach was used to remove the tumours and their attachment with safe resection margins. Conclusions: While malignant lesions require an excision of the mass with resection of all layers of the nasal septum, benign lesions must be typed according to histological considerations in order to plan the most appropriate type of surgical resection.
