title: Endoscopic modified Lothrop approach for the excision of bilateral frontal sinus tumors.
abstract: We describe the use of an endoscopic modified Lothrop approach for clearance of an extensive sinonasal-type hemangiopericytoma of the nasal cavity and paranasal sinuses with bilateral frontal sinus involvement in a 44-year-old woman. The modified Lothrop approach is conventionally used to treat sinusitis, but with some slight modifications to the technique, it can also be used for tumor excision.
