Abstract
The clinical treatment with Nd-YAG laser was carried out on 140 cases in outpatients, during 1988 and 1997. They were treated with high power laser containing 44 leukoplakia, 23 haemangioma, 20 fibroma, 12 papilloma, 12 oral lichen planus, 5 malignant tumors and others.
The purpose of this study was to assess the clinical efficacy of Nd-YAG laser for oral and maxillofacial lesions.
The Nd-YAG laser surgery managed benign tumors, i. e., fibroma, papilloma, granuloma and haemangioma of which size was smaller than 30mm in diameter. However it wasn't able to manage for the case of which size was larger than them, and for some cases which were in the lip.
It showed a good control for leukoplakia within a definite period of time. However, 17 of 44 cases (38.6%) were recurred after laser surgery. Some cases in the site of tongue were changed malignancy, It suggested that we need special care for the cases on the tongue, because of their high malignant frequency. Therefore, we should carry out a biopsy before an operation.
Twelve of 16 cases (75%) with oral lichen planus were recurred, it suggested that the Nd-YAG laser wouldn't be able to manage them, and so we need to compare with the results which were treated with the other type of laser, or the other therapy.
