Usefulness of Endoscopic Modified Lothrop Procedure for Osteoma of the Frontal Recess

Abstract

Osteoma is the most common bone tumor of the facial region. It is a benign, slowly growing neoplasm 
that generally arises from the frontal sinus. Symptomatic patients with chronic rhinosinusitis due to tumor 
obstruction, massive headaches or facial deformity should undergo operation. We report a case of osteoma of the frontal recess. The patient complained of a headache. This was probably due to obstruction of the natural drainage of the frontal sinus, which leads to chronic frontal sinusitis. The patient was treated successfully by the endoscopic modified Lothrop procedure that involved complete removal of the osteoma and wide opening 
of the frontal sinus.
