Abstract
Chronic maxillary sinusitis is one of the common disease in the rhinological field. Recently, severe cases of chronic sinusitis have decreased during the past decade but cases requiring surgical treatment are still frequently encountered. So, we have developed Nd-YAG Laser antrostomy using a flexible fiberscope for maxillary sinusitis. Nd-YAG Laser antrostomy were carried out in 76 cases during the years 1983 to 1985. The results were that 57 cases or 75% of the patients were markedly improved, 17 cases or 22.4% of the patients showed moderatly improved while only 2 cases or 2.6% of the patients showed no improvement. This new operation has been designed which produced minimal surgical injury, and takes into consideraton the physiological anatomy of nose and paranasal sinuses.
