CO2 Microlaser Treatment For Post Operative Complication Following Radical Middle Ear Surgery

It has been difficult to treat chronic otorrhea of post-operative complication following middle ear surgery. Low power CO2 microlaser surgery was applied in 14 cases of infectious chronic otorrher assocoated with radical mastoidectomy of middle ear cholesteatoma. Laser was irradiated at the low level from 1 to 5 watts by defocused beam.Otorrhea was completely stopped in 7 cases and remarkedly decreased in 6 cases. This treatment showed remarkable improvement of infectious region in the middle ear cavity and induced good reepithelization within 3 weeks without any operative complication. This results indicated low power CO2 laser treatment was very safe and usefull for removal infectious soft tissue as well as wound healing in the opened middle ear cavity compared with conventional treatment.
