Although nearly half of all schwannomas involve the head and neck region, nasal and paranasal sinus presentations are quite rare in the literature. Two of the latter cases are presented in this report. In the first, the tumor originated from the nasal septum and was completely excised under local anesthesia. In the second, the schwannoma arose from the left frontal and anterior ethmoidal sinuses. This lesion was totally removed through a combined endoscopic intranasal and external frontoethmoidectomy approach. The patients have shown no tumor recurrence in 6 years and 18 months of follow-up, respectively. The extreme rarity of nasal and paranasal sinus schwannoma is the basis for discussion of these cases.
