Abstract：
OBJECTIVE: To report a single-centre experience in the endoscopic carbon dioxide laser-assisted approach to glomus tympanicum tumours.
METHODS: A retrospective case review was conducted of patients diagnosed with class A1 to B1 glomus tympanicum tumours who underwent exclusive transcanal endoscopic carbon dioxide laser surgery.
RESULTS: Seven patients fulfilled the inclusion criteria. All patients (100 per cent) were women, with a mean age of 65.4 years (standard deviation, 13.6). There were five A2 tumours, one A1 tumour and one B1 tumour. One patient presented with a delayed tympanic membrane perforation needing myringoplasty on follow up. There were no substantial post-operative complications. The mean hospitalisation time was 9.5 hours (standard deviation, 9.8). The mean follow-up period was 32.7 months (standard deviation, 13.1), with all cases having resolution of pulsatile tinnitus and no tumour recurrence.
CONCLUSIONS: The study provides further evidence on the safety and efficacy of endoscopic carbon dioxide laser surgery as a minimally invasive technique for treating early-stage glomus tympanicum tumours.

摘要：
目的：报告单中心在内镜下二氧化碳激光辅助方法治疗鼓室球瘤的经验。
方法：对诊断为A1级至B1级鼓室球肿瘤的患者进行回顾性病例分析，这些患者接受了独家经管内窥镜二氧化碳激光手术。
结果：7例患者符合纳入标准。所有患者（100%）均为女性，平均年龄为65.4岁(标准偏差，13.6)。有五个A2肿瘤，一个A1肿瘤和一个B1肿瘤。一名患者出现延迟的鼓膜穿孔，需要进行鼓膜成形术。术后无实质性并发症。平均住院时间为9.5小时(标准偏差，9.8).平均随访期为32.7个月(标准差，13.1),所有病例均有搏动性耳鸣消退，无肿瘤复发。
结论：这项研究为内镜下二氧化碳激光手术作为治疗早期鼓膜球肿瘤的微创技术提供了进一步的安全性和有效性的证据。
