Benign sinus tumors are a diverse group that may have similar clinical presentations. Common presenting symptoms include nasal obstruction, nosebleeds, tearing, runny nose, and recurrent sinusitis. Patients may also be asymptomatic, presenting with lesions discovered as incidental findings on imaging studies ordered for non-rhinologic purposes. While several of these lesions may have characteristic presentations, as well as endoscopic and radiographic findings, final diagnosis rests on pathological analysis of a biopsy specimen.
In general, these benign sinonasal neoplasms can be divided into several various categories: inverting papillomas, fibro-osseous lesions, neural-related tumors, hamartomas, and vascular tumors. The management of these tumors can vary from complete surgical resection to conservative observation with serial imaging studies such as CT scans. Those tumors that warrant surgical resection can usually be managed with minimally invasive procedures and approaches involving endoscopic or combined endoscopic/open techniques.
