Schwannoma is a type of benign neurogenic tumor which may derive from the nerve sheath. They can occur throughout anybody but rarely manifest in the nasal cavity, representing less than 4% of all head and neck schwannomas. A 68-year-old woman presented to our clinic with a complaint of a mass occupying the space of the maxillary sinus beyond the pterygopalatine fossa. This mass was discovered during a brain magnetic resonance imaging (MRI) test conducted at another hospital during a routine health checkup. Paranasal sinus computed tomography (CT ) and magnetic resonance imaging (MRI) revealed a heterogenous enhancing mass lesion measuring approximately 4.8×2.9×3.6 cm in size. We performed a mass excision via an endoscopic transnasal approach, and she was pathologically diagnosed with a cellular schwannoma. We present a didactic case report to highlight the minimal invasive technique and the absence of postoperative complications and recurrence, along with a relevant literature review.
