Abstract

Objectives

To evaluate the thermal changes and histologic alterations produced in ex vivo and in vivo specimens of oral mucosa by the quantum molecular resonance (QMR) scalpel.

Materials and methods

Using electronic probes positioned within the mandibles of pigs, we measured temperature changes induced in the mucosa during incisions made with (1) a conventional cold blade; (2) a QMR blade; (3) a Nd:YAG laser (1064 nm); (4) an Er:YAG laser (2940 nm). We also evaluated the epithelial, connective, and vascular tissue modifications in 49 biopsy specimens of benign fibrous oral lesions collected with these same surgical instruments.

Results

The QMR blade was the instrument that produced the smallest increases in temperature and the mildest histologic artifacts (0.9 °C; 22.8 μm).

Conclusions

The QMR blade is a useful tool in oral surgery.

用量子分子共振手术刀切开粘膜的实验研究:生物物理和组织学评估

目的评价量子分子共振(QMR)手术刀对离体和体内口腔黏膜热变化和组织学改变的影响。材料和方法使用电子探针放置在猪的下颌骨内，我们测量了在使用(1)传统冷刀片切开时粘膜引起的温度变化;(2) QMR叶片;(3) Nd:YAG激光器(1064 nm);(4) Er:YAG激光器(2940 nm)。我们还评估了用相同手术器械采集的49例良性口腔纤维病变活检标本的上皮、结缔组织和血管组织改变。结果QMR刀片温度升高最小，组织伪影最轻(0.9°C;22.8μm)。结论QMR刀片是口腔外科的一种有效工具。
