目的：探讨XL-射频皮肤治疗仪消融微切泪小点和周围肿物的疗效。

方法：采用射频消融微切治疗7例7眼泪小点和周围肿物患者，其中皮内痣3例，交界痣1例，混合痣伴炎性肉芽肿1例，炎性肉芽肿1例，鳞状上皮乳头状瘤1例。采用分层、点状、片状等治疗方法祛除。术后随访2～6mo，未祛除干净的残留物再次射频消融祛除，随访观察6～60mo。

结果：治疗后患者6例6眼为1次治愈，1例1眼为1次治疗后残留少部分，2次治疗痊愈。患者术后愈合好，无复发，未见瘢痕，无睑缘变形，无泪小点狭窄或闭塞，无溢泪。XL-射频皮肤治疗仪消融祛除泪小点和周围肿物精准性高，不出血，不损伤泪小管结构，不溢泪，无瘢痕，手术时间短，无需住院，治疗后反应轻，患者痛苦小。

结论：XL-射频皮肤治疗仪消融微切泪小点和周围肿物是一项精准度高、疗效显著的治疗技术。

METHODS: XL-radiofrequency ablation skin apparatus was performed on 7 cases(7 eye lesions)of lacrimal punctum neoplasm including 3 intradermal nevus, 1 boundary nevus, 1 mixed nevus with inflammatory granuloma, 1 inflammatory granuloma, and 1 squamous papillary cell tumor by separating layer, point and flake removing methods. The clinical effect was investigated 2-6mo postoperatively and leftover was removed by twice. The postoperative follow-up durations ranged from 6 to 60mo.

RESULTS: Totally 6 cases(6 eye lesions)were cured successfully by once but 1 case by twice. They were all without recurrence, cicatrix, palpebral margin deformity, obstruction of lacrimal punctum, stenosis of lacrimal punctum or epiphora. Micro-resecting the lacrimal punctum neoplasm using the XL-radiofrequency ablation skin apparatus had several advantages, such as high accuracy, no cicatrix, no bleeding, no epiphora, no damage to the structure of lacrimal canaliculus, short operation time, little pain during the procedure, without hospitalization, slight inflammation reaction after procedure.

CONCLUSION: The efficacy of XL-radiofrequency ablation skin apparatus is significantly more evident and highly accurate in micro-resecting lacrimal punctum neoplasm.
