【摘要】 目的 了解老年门诊患者痴呆症的发生率及其相关危险因素。方法 对2007年7月—2009年5月,年龄≥60岁644例门诊患者进行简易智能表(MMSE简易评分)评价,并收集患者文化程度、吸烟、基础疾病、用药史进行危险因素相关分析。结果 样本人群老年痴呆症的发病率为16.0%。与老年性痴呆密切相龄、高血压、脑卒中史、听力受损和视力受损。结论 高龄、高血压、脑卒中是老年性痴呆主要的危险因素,当前的医疗卫生机构应该积极有效地采取措施,控制可变因素,减少老年性痴呆的发生。
Objective To summarize the effectiveness of the temporal island flap pedicled with the perforating branch of zygomatic orbital artery for repairing defects after periocular malignant tumor resection. Methods Between January 2015 and December 2020, 15 patients with periocular malignant tumors were treated. There were 5 males and 10 females with an average age of 62 years (range, 40-75 years). There were 12 cases of basal cell carcinoma and 3 cases of squamous carcinoma. The disease duration ranged from 5 months to 10 years (median, 2 years). The size of tumors ranged from 1.0 cm×0.8 cm to 2.5 cm×1.5 cm, without tarsal plate invasion. After extensive resection of the tumors, the left defects in size of 2.0 cm×1.5 cm to 3.5 cm×2.0 cm were repaired with the temporal island flap pedicled with the perforating branch of zygomatic orbital artery via subcutaneous tunnel. The size of the flaps ranged from 3.0 cm×1.5 cm to 5.0 cm×2.0 cm. The donor sites were separated subcutaneously and sutured directly. Results All flaps survived after operation and the wounds healed by first intention. The incisions at donor sites healed by first intention. All patients were followed up 6-24 months (median, 11 months). The flaps were not obviously bloated, the texture and color were basically the same as the surrounding normal skin, and the scars at recipient sites were not obviously. There was no complication such as ptosis, ectropion, or incomplete closure of the eyelids and recurrence of tumor during follow-up. Conclusion The temporal island flap pedicled with the perforating branch of zygomatic orbital artery can repair the defects after periorbital malignant tumors resection and has the advantages of reliable blood supply, flexible design, and good morphology and function.
