A 19-year-old Hispanic nullipara experienced the rapid growth of an oral lesion on the right lower gingiva which she had first noticed at 29 weeks gestation. The lesion interfered with oral hygiene and eating. At surgery, the lesion measured 3.5 x 2.5 x 2.0 cm. Biopsy confirmed a pyogenic granuloma ("granuloma gravidarum"). Panorex films showed no bony invasion. The lesion was excised using the Nd:YAG laser under general anesthesia when the patient had reached 36 3/7 weeks gestation. We chose the Nd:YAG laser over the CO2 laser for the removal of this very vascular lesion, because of its superior coagulation characteristics. This technique results in removal of the lesion with less danger of bleeding than with any other surgical technique. The patient did well postoperatively, delivered a healthy 3,884 g infant at 40 6/7 weeks gestation, and has had no recurrence after 15 months of follow-up.
一名19岁未生育的西班牙裔女性，在妊娠29周时首次发现右下牙龈有一处口腔病变迅速生长。该病变影响口腔卫生和进食。手术时，病变大小为3.5×2.5×2.0厘米。活检确诊为化脓性肉芽肿（“妊娠性肉芽肿”）。全景片显示无骨质侵犯。当患者妊娠36 3/7周时，在全身麻醉下使用Nd:YAG激光切除病变。由于其出色的凝血特性，我们选择Nd:YAG激光而非CO2激光来切除这个血管丰富的病变。与其他任何手术技术相比，该技术切除病变时出血风险更低。患者术后恢复良好，在妊娠40 6/7周时产下一名健康的3884克婴儿，随访15个月后无复发。
