Abstract

Inverted papilloma of the nasal cavity and paranasal sinuses is a relatively uncommon benign tumor. Because of the aggressive nature and risk of recurrence of the tumor, complete resection is essential.<BR>We report a patient with a massive inverted papilloma of the maxillary sinus who was surgically treated by a collaborative medical team approach, including otorhinolaryngology specialists and oral surgeons. The patient was a 50-year-old woman who consulted an otorhinolaryngologist at a primary care center in early June 2010 because of left nasal obstruction. A left nasal polyp was resected. The histopathological diagnosis was an inverted papilloma.<BR>In early July 2010, she was referred to the Division of Otolaryngology at Ebina General Hospital. Computed tomography revealed a mass of different density in the left maxillary sinus and nasal cavity. The clinical diagnosis was a suspected massive inverted papilloma of the left maxillary sinus.<BR>In mid-July 2010, otorhinolaryngology specialists were consulted and resection of the tumor was considered difficult by endoscopic sinus surgery （ESS） alone. In September 2010, the patient underwent tumor resection combined with the Caldwell-Luc operation under general anesthesia in collaboration with our department. The histopathological diagnosis was an inverted papilloma.<BR>No recurrence has occurred as of 36 months after the operation.
