Objective:
The purpose of this study was to describe our experience in the surgical treatment of frontal sinus osteomas.
Methods:
This study involved 18 patients who underwent surgery for frontal sinus osteoma between January 2016 and December 2019. Demographic characteristics, site and size of osteoma, presenting symptoms, frontal sinus osteoma grading system, presence of frontal sinusitis, surgical methods, treatment outcome, operation time, and complications were reviewed.
Results:
The endoscopic approach was performed in all patients except one. Among patients who underwent an endoscopic approach, endoscopic sinus surgery was performed in ten patients and endoscopic-modified Lothrop procedure was performed in seven patients. The mean size of the frontal sinus osteoma was 1.5 ± 0.7 cm. According to the frontal sinus osteoma grading system, grade III (n = 9, 50.0%) was the most common, followed by grade II (n = 4), grade I (n = 3), and grade IV (n = 2). The size of the osteoma and frontal osteoma grading system exhibited statistical significance with the operation time (p < 0.05). There were no major surgical complications or recurrence.
Conclusion:
The operation time was prolonged when the frontal sinus osteomas were more than 1.5 cm or in grade III and IV frontal osteomas.
