The laser and the nasal septum--a histological study.
We studied the histopathological effects of CO2 laser use on the nasal septum of nine rabbits. In the rabbits irradiated with no more than three bursts at four watts, healing was prompt and complete; more than three bursts caused cartilage necrosis. The CO2 laser, using appropriate settings, is safe and effective in treating anterior septal lesions. These settings can be established only after histological examination of the lesions.
