Frontal sinus cyst is a relative common disease; however, this disease is often difficult to manage clinically since recurrence sometimes occurs even if patients are treated with surgery. We retrospectively analyzed 30 cases of the frontal sinus cyst, treated with surgery in our hospital between 1994 and 2006. The most common symptom was forehead swelling, followed by forehead pain, exophthalmos, and double vision; however, 3 (10％) cases did not have any clinical symptoms. Of 30 cases, 16 (53.3％) were postoperative cysts, and 14 (46.7％) were idiopathic cysts. Thirteen (43.3％) cases were treated by an external approach, and 12 (40.0％) cases were treated by an external approach combined with endonasal sinus surgery (ESS). Five (16.7％) cases were treated by ESS without external incision. The overall postoperative patency rate was 72.4％. The patency rate treated by the external approach, external approach combined with ESS, and ESS alone was 66.7％, 75.0％, and 80.0％, respectively. Although the number of patients treated by ESS alone was small, the clinical outcome of ESS was favorable. In several endonasal approaches, the endoscopic modified Lothrop procedure has been performed, and the postoperative clinical course is good. Thus, a modified Lothrop procedure might be a useful approach for frontal sinus cysts. The findings of the present study suggest that ESS would be the first choice of surgical approach for frontal sinus cysts.
