Methods: a total of 78 patients were selected in this study, who underwent nasal tip plastic surgery in our hospital from January 2021 to January 2022. They were randomly assigned into two groups according to the odd-even series method. The experimental group and the conventional group were treated with artificial dermis and silica gel nasal augmentation, respectively, to compare the surgical effects. Results: 97.44% of the patients in the experimental group had effective nasal tip plastic surgery, while only 84.62% of the patients in the conventional group had effective nasal tip plastic surgery, which was statistically significant (P < 0.05). After plastic surgery, the nasal tip protrusion, nasal length and nasal tip height in the experimental group were significantly higher than those in the conventional group, and the statistical significance was established (P < 0.05). In the experimental group, 5.13% of the patients had complications after nasal tip plastic surgery, the total incidence rate was lower than 20.51% in the conventional group, and the statistical significance was established (P < 0.05). 97.44% of the patients in the experimental group were satisfied with the nasal tip plastic surgery, while only 82.05% of the patients in the conventional group were satisfied, which was statistically significant (P < 0.05). Conclusion: in the process of nasal tip plastic surgery, the overall application effect of artificial dermis is better than that of silica gel nasal augmentation, which is more worthy of promotion and application in clinic.展开更多

We used a diode laser with a wavelength of （980 ±10）nm and average power of 10 W. The diode laser was operated in continuous wave （CW） and pulsed modes. In CW mode, the average laser radiation power was 10 W; in pulsed mode, the average laser radiation power was I0 W and the peak power was 20 W. Diode laser radiation was delivered to soft tissue （chicken meat） using a quartz optical fiber with either a clear distal end （clear tip） or a distal end containing an optothermal converter （hot tip）. Application of the diode laser in pulsed mode resulted in crater depths and areas of collateral damage in soft tissue about 1.6 times greater than those observed in CW mode at treatment with the clear tip. Significant differences in the crater depth and collateral damage width of chicken meat were not found after hot-tip treatment with the diode laser in CW and pulsed modes. Soft tissue treated with the hot tip showed crater depths about 3.4 times greater than those observed after treatment with the clear tip. Hot tip treatment further resulted in collateral damage widths about 2.7 times lower than those obtained after treatment with the clear tip.展开更多
