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.

D009300	Nasal Septum	The partition separating the two NASAL CAVITIES in the midplane. It is formed by the SEPTAL NASAL CARTILAGE, parts of skull bones (ETHMOID BONE; VOMER), and membranous parts.	Nasal Septums,Septum, Nasal,Septums, Nasal
D009442	Neurilemmoma	A neoplasm that arises from SCHWANN CELLS of the cranial, peripheral, and autonomic nerves. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance.

D004724	Endoscopy	Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument through a small incision in the skin i.e., percutaneous; or through a natural orifice and along natural body pathways such as the digestive tract; and/or through an incision in the wall of a tubular structure or organ, i.e. transluminal, to examine or perform surgery on the interior parts of the body.
